经研究发现，网关在获取到应用请求后，仅利用应用请求中的路由特征信息进行请求调度。具体的，网关利用路由特征信息确定可接收应用请求的服务器，再将应用请求调度至服务器，即实现了应用请求的调度。但仅依赖路由特征信息进行请求调度，存在请求调度的粒度较粗，调度效果较差的问题。After research, it was found that after obtaining the application request, the gateway only uses the routing feature information in the application request to schedule the request. Specifically, the gateway uses the routing feature information to determine the server that can receive the application request, and then schedules the application request to the server, thereby realizing the scheduling of the application request. However, relying only on routing feature information for request scheduling has the problem of coarser granularity of request scheduling and poor scheduling effect.

基于上述研究，本公开提供了一种请求调度方案，通过在第一请求中提取请求上下文信息的方式，可以得到多条能够用于请求调度的请求特征信息，进而依赖包含丰富信息的请求上下文信息进行请求调度，能够实现细粒度的请求调度，提高请求调度的准确性。利用预先配置的路由配置信息中配置的请求处理信息，对请求上下文信息进行处理，能够实现将请求上下文信息修改为满足配置信息的目标上下文信息，实现了对目标上下文的细粒度更新。再通过目标上下文信息生成第二请求，并将所述第二请求发送至目标服务器进行处理的方式，第二请求对应于第一请求，利用目标服务器对第二请求处理，也即实现了对第一请求进行及时地调度处理。最后，基于请求处理信息，对目标服务器针对第二请求反馈的第一响应内容进行修改，实现了细粒度地将第一响应内容修改为满足配置信息的第二响应内容，也即得到了更准确且更符合预期的响应结果。Based on the above research, the present disclosure provides a request scheduling solution. By extracting the request context information in the first request, multiple pieces of request feature information that can be used for request scheduling can be obtained, and then rely on the request context information containing rich information. Request scheduling can achieve fine-grained request scheduling and improve the accuracy of request scheduling. Using the request processing information configured in the preconfigured routing configuration information to process the request context information, the request context information can be modified to the target context information that satisfies the configuration information, and fine-grained updates to the target context can be achieved. Then generate a second request through the target context information, and send the second request to the target server for processing. The second request corresponds to the first request, and the target server is used to process the second request, that is, the second request is processed. A request is dispatched and processed in a timely manner. Finally, based on the request processing information, the first response content fed back by the target server for the second request is modified, achieving fine-grained modification of the first response content to the second response content that satisfies the configuration information, that is, a more accurate And more consistent with the expected response results.

请求上下文信息包括多种请求特征信息，不同的请求特征信息用于表征第一请求中的不同特征。具体的，请求特征信息可以包括方法特征信息(method)、路由特征信息、请求头信息(header)、主体信息(body)、客户端地址信息等，其中，路由特征信息可以包括请求域名信息(host)和访问路径(path)，请求头信息中还可以包括cookie信息。The request context information includes a variety of request feature information, and different request feature information is used to characterize different features in the first request. Specifically, the request characteristic information may include method characteristic information (method), routing characteristic information, request header information (header), body information (body), client address information, etc., wherein the routing characteristic information may include request domain name information (host ) and access path (path), the request header information can also include cookie information.

具体实施时，功能网关在接收到应用客户端发送的第一请求之后，可以对第一请求进行特征提取，从中提取出method、header、body、host、path、cookie、客户端地址等多种请求特征信息，之后，可以将提取的上述多种请求特征信息存储为第一请求对应的请求上下文信息。During specific implementation, after receiving the first request sent by the application client, the function gateway can perform feature extraction on the first request, and extract multiple requests such as method, header, body, host, path, cookie, client address, etc. Feature information, and then the extracted multiple request feature information can be stored as request context information corresponding to the first request.

S102：基于获取的预先配置的路由配置信息和请求上下文信息中的路由特征信息，确定第一请求对应的目标服务器和请求处理信息。S102: Determine the target server and request processing information corresponding to the first request based on the obtained preconfigured routing configuration information and the routing feature information in the request context information.

这里，路由配置信息可以预先配置在功能网关中。路由配置信息中可以包括多条路由配置，每条路由配置对应于一个请求域名(host)、该请求域名下的预设访问路径(path)，以及预设访问路径对应的配置信息。一个请求域名下的预设访问路径可以包括一个或多个，不同的预设访问路径可以对应于不同的配置信息。配置信息中可以包括预设访问路径对应的服务器端口信息和IP地址信息，以及请求处理信息(filter列表配置)。请求处理信息用于对请求上下文信息进行处理，根据服务器端口信息和IP地址信息可以确定预设访问路径对 应的服务器，服务器端口信息和IP地址信息统称为upstream。Here, routing configuration information can be pre-configured in the functional gateway. The routing configuration information may include multiple routing configurations, each routing configuration corresponding to a request domain name (host), a preset access path (path) under the request domain name, and configuration information corresponding to the preset access path. The preset access paths under a requested domain name may include one or more, and different preset access paths may correspond to different configuration information. The configuration information may include server port information and IP address information corresponding to the preset access path, as well as request processing information (filter list configuration). The request processing information is used to process the request context information. The preset access path pair can be determined based on the server port information and IP address information. The corresponding server, server port information and IP address information are collectively called upstream.

一个请求域名下的各个预设访问路径为在访问该域名的情况下，可能访问的各个路径。Each preset access path under a requested domain name is each path that may be accessed when accessing the domain name.

目标服务器即为确定出的可以对第一请求进行处理的服务器。第一请求对应的请求处理信息，用于对第一请求对应的请求上下文信息进行处理。The target server is the determined server that can process the first request. The request processing information corresponding to the first request is used to process the request context information corresponding to the first request.

具体实施时，功能网关可以获取存储的最新的路由配置信息，以及可以从请求上下文信息中筛选出路由特征信息。然后，可以基于路由配置信息和路由特征信息，进行路由匹配，以确定出路由特征信息对应的配置信息。之后，可以确定配置信息中携带的upstream对应的服务器，将该服务器作为目标服务器，将配置信息中携带的请求处理信息作为第一请求对应的请求处理信息。During specific implementation, the function gateway can obtain the latest stored routing configuration information, and can filter out routing feature information from the request context information. Then, route matching can be performed based on the routing configuration information and the routing feature information to determine the configuration information corresponding to the routing feature information. Afterwards, the server corresponding to the upstream carried in the configuration information can be determined, the server is used as the target server, and the request processing information carried in the configuration information is used as the request processing information corresponding to the first request.

在一种实施例中，S102可以按照以下步骤实施：In one embodiment, S102 can be implemented according to the following steps:

S102-1：根据路由特征信息中的请求域名，从路由配置信息中获取在请求域名下的各个预设访问路径。S102-1: According to the requested domain name in the routing feature information, obtain each preset access path under the requested domain name from the routing configuration information.

具体实施时，路由配置信息中包括的多条路由配置可以以树状形式组织，其中，第一级为host，第二级为path。例如，请求域名为“example.com”，path分别为“/a”和“/b”时，以json语言表示对应的路由配置为“{"example.com":{"/a":data1,"/b":data2}}”。During specific implementation, multiple routing configurations included in the routing configuration information may be organized in a tree form, where the first level is host and the second level is path. For example, when the requested domain name is "example.com" and the paths are "/a" and "/b", the corresponding routing configuration expressed in json language is "{"example.com":{"/a":data1, "/b":data2}}".

具体实施时，可以确定路由特征信息中的host，然后根据该host，在路由配置信息中包括的多条路由配置中，确定在该host下的全部预设访问路径。例如，在host为“example.com”的情况下，确定出的全部预设访问路径可以包括“/a”和“/b”。During specific implementation, the host in the routing feature information can be determined, and then based on the host, all preset access paths under the host are determined among multiple routing configurations included in the routing configuration information. For example, when the host is "example.com", all determined preset access paths may include "/a" and "/b".

S102-2：从预设访问路径中，确定与路由特征信息中的目标访问路径相匹配的各个候选访问路径，候选访问路径对应的路径长度小于或等于目标访问路径的路径长度。S102-2: From the preset access paths, determine each candidate access path that matches the target access path in the routing feature information. The path length corresponding to the candidate access path is less than or equal to the path length of the target access path.

这里，目标访问路径为第一请求对应的路由特征信息中携带的path。Here, the target access path is the path carried in the routing feature information corresponding to the first request.

具体实施时，可以根据目标访问路径，确定目标访问路径对应的各个父级path。例如，在目标访问路径为“/a/b/c”的情况下，父级path可以为“/a/b/c”、“/a/b”、“/a”和“/”。During specific implementation, each parent path corresponding to the target access path can be determined based on the target access path. For example, in the case where the target access path is "/a/b/c", the parent paths can be "/a/b/c", "/a/b", "/a" and "/".

进而，可以将目标访问路径对应的各个父级path和目标访问路径，分别与在请求域名下的各个预设访问路径进行匹配，确定出各个候选访问路径。例 如，匹配出的候选访问路径可以为“/a/b”、“/a”和“/”。Furthermore, each parent path and target access path corresponding to the target access path can be matched with each preset access path under the requested domain name, and each candidate access path can be determined. example For example, the matched candidate access paths can be "/a/b", "/a" and "/".

S102-3：确定各个候选访问路径中，路径长度最长的候选访问路径对应的目标配置信息，并从目标配置信息中确定目标服务器和请求处理信息。S102-3: Determine the target configuration information corresponding to the candidate access path with the longest path length among each candidate access path, and determine the target server and request processing information from the target configuration information.

这里，目标配置信息即为路径长度最长的候选访问路径对应的配置信息。Here, the target configuration information is the configuration information corresponding to the candidate access path with the longest path length.

示例性的，在匹配出的候选访问路径为“/a/b”、“/a”和“/”的情况下，可以将路径长度最长的候选访问路径“/a/b”对应的配置信息作为目标配置信息。进而，可以从目标配置信息中提取出第一请求对应的upstream和请求处理信息(filter列表配置)，并基于upstream确定第一请求对应的目标服务器。For example, when the matched candidate access paths are "/a/b", "/a" and "/", the candidate access path "/a/b" with the longest path length can be configured accordingly. information as target configuration information. Furthermore, the upstream and request processing information (filter list configuration) corresponding to the first request can be extracted from the target configuration information, and the target server corresponding to the first request is determined based on the upstream.

S103：根据请求处理信息对请求上下文信息进行处理，得到处理后的目标上下文信息。S103: Process the request context information according to the request processing information to obtain processed target context information.

具体实施时，可以根据请求处理信息中携带的针对至少部分请求上下文信息的转换方式，对部分请求上下文信息进行转换，得到目标上下文信息。During specific implementation, the partial request context information may be converted according to the conversion method for at least part of the request context information carried in the request processing information to obtain the target context information.

示例性的，在灰度测试场景下，可以根据第一请求中携带的客户端标识，确定发起第一请求的应用客户端是否属于可进行灰度测试的目标用户，如果是，则可以对请求上下文信息中的method进行更改。For example, in a grayscale test scenario, it can be determined according to the client identifier carried in the first request whether the application client that initiated the first request belongs to the target user who can perform grayscale testing. If so, the request can be processed. method in the context information.

在一种实施例中，S103可以按照以下步骤实施：按照请求处理信息指示的、在第一处理阶段针对请求上下文信息的请求处理操作，对请求上下信息中的请求头信息和/或客户端地址信息进行修改，得到目标上下文信息。In one embodiment, S103 can be implemented according to the following steps: According to the request processing operation for the request context information in the first processing stage as indicated by the request processing information, process the request header information and/or client address in the request context information. The information is modified to obtain the target context information.

这里，请求处理信息即filter列表配置，可以指示有在多个处理阶段分别对应的处理操作。其中，多个处理阶段可以包括用于对请求上下文信息进行处理的第一处理阶段(也称before_request阶段)，对请求上下文信息进行检查的第二处理阶段(也称before_proxy阶段)，对服务器反馈的响应内容进行处理的第三处理阶段(也称response_header阶段)，以及在第一请求响应完毕后针对第一请求的第四处理阶段(也称response_end阶段)。Here, the request processing information, that is, the filter list configuration, can indicate corresponding processing operations in multiple processing stages. Among them, the multiple processing stages may include a first processing stage for processing request context information (also called before_request stage), a second processing stage for checking request context information (also called before_proxy stage), and a processing stage for server feedback. The third processing stage for processing the response content (also called the response_header stage), and the fourth processing stage for the first request after the response to the first request is completed (also called the response_end stage).

具体实施时，在确定filter列表配置后，可以执行filter列表配置指示的before_request阶段，并按照filter列表配置指示的before_request阶段对应的请求处理操作，对请求上下信息中的请求头信息和/或客户端地址信息进行修改，得到目标上下文信息。在得到目标上下信息的情况下，确定before_request阶段执行完成。During specific implementation, after the filter list configuration is determined, the before_request stage indicated by the filter list configuration can be executed, and the request header information and/or client in the request context information can be processed according to the request processing operations corresponding to the before_request stage indicated by the filter list configuration. The address information is modified to obtain the target context information. After obtaining the target context information, it is determined that the before_request phase is completed.

例如，获取请求头信息携带的会话标识(session id)，可以确定按照请求 处理操作对应的转换方式，将会话标识转换为用户标识，将携带用户标识的请求头信息以及未进行更改的其他请求特征信息，一起作为目标上下文信息。For example, by obtaining the session ID carried in the request header information, you can determine whether the Process the conversion method corresponding to the operation, convert the session ID into a user ID, and use the request header information carrying the user ID and other request feature information that has not been changed as the target context information.

又例如，获取客户端地址信息，按照请求处理操作对应的地址解析方式，对客户端地址信息进行解析，得到目标地址信息。之后，将目标地址信息和未进行更改的其他请求特征信息，一起作为目标上下文信息。For another example, obtain the client address information, parse the client address information according to the address resolution method corresponding to the request processing operation, and obtain the target address information. Afterwards, the target address information and other request characteristic information that have not been changed are used as the target context information.

需要说明的是，可以根据具体的开发需要对filter列表配置进行设置。在具体实施时，可以利用设置好的filter列表配置，对请求上下文信息中的任一请求特征信息进行更改，本公开实施例不进行限定。It should be noted that the filter list configuration can be set according to specific development needs. During specific implementation, the set filter list configuration can be used to change any request feature information in the request context information, which is not limited by the embodiments of the present disclosure.

可选的，如果请求上下文信息中的各个请求特征信息均满足预设特征条件，在执行before_request阶段时，可以不对请求上下文信息进行修改，直接将请求上下文信息作为目标上下文信息。Optionally, if each request feature information in the request context information satisfies the preset feature conditions, when executing the before_request stage, the request context information may not be modified and the request context information may be directly used as the target context information.

S104：根据目标上下文信息生成第二请求，将第二请求发送至目标服务器，并在获取目标服务器针对第二请求反馈的第一响应内容后，基于请求处理信息对第一响应内容进行处理，将处理后的第二响应内容作为第一请求的响应结果反馈给应用客户端。S104: Generate a second request based on the target context information, send the second request to the target server, and after obtaining the first response content fed back by the target server in response to the second request, process the first response content based on the request processing information, and The processed second response content is fed back to the application client as the response result of the first request.

这里，第二请求为功能网关根据目标上下文信息，构造的用于代理第一请求的请求。目标服务器反馈的针对第二请求的响应内容，可以作为第一请求对应的响应内容。处理后的第二响应内容为对第一响应内容进行处理后得到的响应内容。Here, the second request is a request constructed by the functional gateway based on the target context information for proxying the first request. The response content for the second request fed back by the target server can be used as the response content corresponding to the first request. The processed second response content is the response content obtained after processing the first response content.

具体实施时，功能网关可以根据目标上下文信息，构造第二请求并将第二请求发送至目标服务器。在另一种实施方式中，如果目标上下文为未修改的请求上下文信息，则功能网关也可以将第一请求直接作为第二请求转发至目标服务器。During specific implementation, the function gateway may construct the second request according to the target context information and send the second request to the target server. In another implementation, if the target context is unmodified request context information, the function gateway may also forward the first request directly to the target server as the second request.

之后，目标服务器可以对第二请求进行响应处理，得到第二请求对应的第一响应内容，并将第二响应内容反馈给功能网关。功能网关在得到第一响应内容后，可以获取第一响应内容中携带的响应头信息，并将响应头信息存储为响应上下文信息。或者，也可以直接将第一响应内容作为响应上下文信息。Afterwards, the target server can respond to the second request, obtain the first response content corresponding to the second request, and feed back the second response content to the functional gateway. After obtaining the first response content, the functional gateway may obtain the response header information carried in the first response content, and store the response header information as response context information. Alternatively, the first response content can also be directly used as the response context information.

然后，功能网关可以执行filter列表配置指示的response_header阶段，并按照response_header阶段对应的处理操作，对第一响应内容进行处理。例如，对响应内容中携带的页面颜色信息进行更改，对响应内容中携带的页面尺寸信 息进行修改等等。进一步的，可以将处理后的第一响应内容作为第二响应内容，并将第二响应内容作为第一请求对应的响应结果反馈给应用客户端。Then, the function gateway can execute the response_header stage indicated by the filter list configuration, and process the first response content according to the processing operations corresponding to the response_header stage. For example, change the page color information carried in the response content, change the page size information carried in the response content Modify the information and so on. Further, the processed first response content may be used as the second response content, and the second response content may be fed back to the application client as the response result corresponding to the first request.

在一种可选的实施方式中，也可以不配置response_header阶段，也即，也可以不对第一响应内容进行处理，将第一响应内容直接作为第一请求对应的响应结果并反馈给应用客户端。或者，在配置response_header阶段的情况下，如果第一响应内容符合标准，也可以不执行response_header阶段，也即可以不对第一响应内容进行处理，将第一响应内容直接作为第一请求对应的响应结果并反馈给应用客户端。In an optional implementation, the response_header stage may not be configured, that is, the first response content may not be processed, and the first response content may be directly used as the response result corresponding to the first request and fed back to the application client. . Alternatively, when the response_header stage is configured, if the first response content meets the standard, the response_header stage may not be executed, that is, the first response content may not be processed, and the first response content may be directly used as the response result corresponding to the first request. and feedback to the application client.

这样，通过在第一请求中提取请求上下文信息的方式，可以得到多条能够用于请求调度的请求特征信息，进而依赖包含丰富信息的请求上下文信息进行请求调度，能够实现细粒度的请求调度，提高请求调度的准确性。利用预先配置的路由配置信息中配置的请求处理信息，对请求上下文信息进行处理，能够实现将请求上下文信息修改为满足配置信息的目标上下文信息，实现了对目标上下文的细粒度更新。再通过目标上下文信息生成第二请求，并将所述第二请求发送至目标服务器进行处理的方式，第二请求对应于第一请求，利用目标服务器对第二请求处理，也即实现了对第一请求进行及时地调度处理。最后，基于请求处理信息，对目标服务器针对第二请求反馈的第一响应内容进行修改，实现了细粒度地将第一响应内容修改为满足配置信息的第二响应内容，也即得到了更准确且更符合预期的响应结果。In this way, by extracting the request context information in the first request, multiple pieces of request characteristic information that can be used for request scheduling can be obtained, and then relying on the request context information containing rich information for request scheduling can achieve fine-grained request scheduling. Improve the accuracy of request scheduling. Using the request processing information configured in the preconfigured routing configuration information to process the request context information, the request context information can be modified to the target context information that satisfies the configuration information, and fine-grained updates to the target context can be achieved. Then generate a second request through the target context information, and send the second request to the target server for processing. The second request corresponds to the first request, and the target server is used to process the second request, that is, the second request is processed. A request is dispatched and processed in a timely manner. Finally, based on the request processing information, the first response content fed back by the target server for the second request is modified, achieving fine-grained modification of the first response content to the second response content that satisfies the configuration information, that is, a more accurate And more consistent with the expected response results.

在一种实施例中，请求处理信息中可以携带有各种method在具有不同请求标识的应用客户端请求时，目标服务器对应的目标接收频率。目标接收频率例如可以为针对对应于method1和请求标识1的请求，每分钟可响应100个。请求标识可以为用户标识、客户端标识等。在将第二请求发送至目标服务器之前，还可以执行before_proxy阶段，以实现对第一请求的限流检查，确定目标服务器能否响应第一请求对应第二请求。In one embodiment, the request processing information may carry the target reception frequency corresponding to the target server when various methods are requested by application clients with different request identifiers. The target reception frequency may be, for example, 100 responses per minute for requests corresponding to method 1 and request identifier 1. The request ID can be a user ID, client ID, etc. Before sending the second request to the target server, the before_proxy stage can also be executed to implement a current limit check on the first request and determine whether the target server can respond to the first request corresponding to the second request.

具体的，可以基于目标上下文信息，确定第一请求对应的请求标识和请求方式，也即从目标上下文信息中，筛选出第一请求对应的method和method。并且，还可以基于请求处理信息，确定目标服务器针对第一请求对应的请求方式和请求标识的目标接收频率。Specifically, the request identifier and request method corresponding to the first request can be determined based on the target context information, that is, the method and method corresponding to the first request can be filtered out from the target context information. Furthermore, the request method corresponding to the first request and the target reception frequency of the request identifier by the target server may also be determined based on the request processing information.

然后，确定与第一请求对应的请求方式和请求标识均匹配的请求的当前接 收频率。这里，当前接收频率可以为与第一请求对应的请求方式和请求标识均匹配的请求，在目标接收频率指示的时间段内的接收数量。Then, determine the current interface of the request that matches both the request method and the request identifier corresponding to the first request. receive frequency. Here, the current reception frequency may be the number of requests received within the time period indicated by the target reception frequency for requests that both match the request mode and request identifier corresponding to the first request.

示例性的，第一请求对应的请求方式为method2，请求标识为标识2，目标接收频率为每分钟接收10次，在确定目标接收频率后确定的一分钟内已接收的、对应于method2和标识2的请求的数量为5，则可以确定当前接收频率为一分钟接收了5次。For example, the request mode corresponding to the first request is method2, the request identifier is identifier 2, the target reception frequency is 10 times per minute, and the data corresponding to method2 and identifier has been received within one minute after the target reception frequency is determined. If the number of requests for 2 is 5, it can be determined that the current reception frequency is 5 times per minute.

进一步的，可以执行请求处理信息指示的、在before_proxy阶段针对第一请求的限流检查操作，也即确定当前接收频率是否小于目标接收频率。如果是，则确定目标服务器能够响应第一请求对应的第二请求。继而，可以根据目标上下文信息，生成第二请求，并将第二请求发送至目标服务器。Further, the current limit check operation for the first request in the before_proxy stage as indicated by the request processing information can be performed, that is, it is determined whether the current reception frequency is less than the target reception frequency. If yes, it is determined that the target server can respond to the second request corresponding to the first request. Then, a second request can be generated according to the target context information, and the second request can be sent to the target server.

在另一种实施例中，在确定当前接收频率不小于目标接收频率的情况下，则说明目标服务器不能对第二请求进行响应，则可以获取请求处理信息中指示的第一备用服务器。其中，第一备用服务器为一个兜底的服务器，在任何时刻确定当前接收的请求不能被该请求对应的目标服务器响应时，均可以将该请求发送至第一备用服务器。In another embodiment, if it is determined that the current reception frequency is not less than the target reception frequency, it means that the target server cannot respond to the second request, and the first backup server indicated in the request processing information can be obtained. The first backup server is a back-up server. When it is determined that the currently received request cannot be responded to by the target server corresponding to the request at any time, the request can be sent to the first backup server.

然后，可以将第二请求发送至第一备用服务器，并获取第一备用服务器对第二请求进行响应处理后反馈的响应内容。之后，可以基于请求处理信息对该响应内容进行处理，得到处理后的内容，并将该处理后的内容反馈给应用客户端。或者，也可以将第一备用服务器对第二请求进行响应处理后反馈的响应内容，直接反馈给应用客户端。Then, the second request can be sent to the first backup server, and the response content fed back by the first backup server after processing the response to the second request can be obtained. Afterwards, the response content can be processed based on the request processing information to obtain the processed content, and the processed content can be fed back to the application client. Alternatively, the response content fed back by the first backup server after processing the response to the second request can also be directly fed back to the application client.

这样，通过在请求处理信息中设置兜底的第一备用服务器并利用第一备用服务器对第二请求进行响应的方式，可以保证在目标服务器不能对第二请求进行响应的情况下，第二请求也能够被及时响应，提高了请求响应的及时性。In this way, by setting a first backup server in the request processing information and using the first backup server to respond to the second request, it can be ensured that when the target server cannot respond to the second request, the second request can still be processed. Can be responded to in a timely manner, improving the timeliness of request response.

在一种实施例中，针对S104中基于请求处理信息对第一响应内容进行处理的步骤，还可以按照两种方式(方式一和方式二)中的任一方式实施：In one embodiment, the step of processing the first response content based on the request processing information in S104 can also be implemented in any of two ways (way one and way two):

方式一、在确定第一响应内容中携带的状态码指示响应异常的情况下，将第二请求转发至第二备用服务器，并接收第二备用服务器反馈的第三响应内容，利用第三响应内容对第一响应内容进行更新，得到第二响应内容。Method 1: When it is determined that the status code carried in the first response content indicates that the response is abnormal, forward the second request to the second backup server, receive the third response content fed back by the second backup server, and use the third response content Update the first response content to obtain the second response content.

这里，第一响应内容中可以包括响应头信息、状态码、响应日期、文件类型(图片、页面、视频等)、目标服务器标识等信息。响应头信息用于表征目 标服务器饭反馈的针对第二请求的反馈内容。例如，响应头信息可以为页面文件信息、功能响应信息等。状态码用于指示目标服务器是否正常响应了第二请求。例如，状态码可以为指示目标服务器响应异常的404、指示目标服务器响应成功的200、指示目标服务器不可用的503等。Here, the first response content may include response header information, status code, response date, file type (picture, page, video, etc.), target server identification and other information. Response header information is used to represent the purpose The feedback content of the second request provided by the server. For example, the response header information can be page file information, function response information, etc. The status code is used to indicate whether the target server responded to the second request normally. For example, the status code may be 404 indicating that the target server responded abnormally, 200 indicating that the target server responded successfully, 503 indicating that the target server is unavailable, etc.

第二备用服务器可以与第一备用服务器相同，也可以不同，此处不进行限定。利用第三响应内容对第一响应内容进行更新，得到第二响应内容的操作，具体可以为将第三响应内容直接作为第二响应内容的操作。The second backup server may be the same as the first backup server, or may be different, which is not limited here. The operation of updating the first response content with the third response content to obtain the second response content may specifically be the operation of directly using the third response content as the second response content.

具体实施时，可以执行response_header阶段，并按照response_header阶段对应的响应内容检查操作，对第一响应内容进行解析，获取第一响应内容中的状态码和响应头信息。之后，确定状态码是否指示目标服务器响应异常。如果是，则将第二请求转发至第二备用服务器，并接收第二备用服务器反馈的第三响应内容，将第三响应内容作为第二响应内容，并反馈给应用客户端。During specific implementation, the response_header stage can be executed, and the first response content can be parsed according to the response content checking operation corresponding to the response_header stage, and the status code and response header information in the first response content can be obtained. Afterwards, determine whether the status code indicates that the target server responded abnormally. If so, forward the second request to the second backup server, receive the third response content fed back by the second backup server, use the third response content as the second response content, and feed it back to the application client.

或者，在确定状态码指示响应异常的情况下，可以将默认的第二响应内容反馈给应用客户端。Alternatively, if it is determined that the status code indicates a response exception, the default second response content may be fed back to the application client.

方式二、在确定第一响应内容中携带的状态码指示响应正常的情况下，可以利用请求处理信息中携带的内容更新信息，对第一响应内容中的响应头信息进行更改，从而得到第二响应内容。Method 2: When it is determined that the status code carried in the first response content indicates that the response is normal, the content update information carried in the request processing information can be used to change the response header information in the first response content, thereby obtaining the second Response content.

在具体实施时，在请求头信息为响应上下文信息的情况下，例如可以利用请求处理信息中携带的页面内容更新信息，对响应上下文信息中的页面内容进行更新(例如置灰、更换颜色等)，从而得到更新后的响应上下文信息，基于更新后的响应上下文信息，可以生成第二响应内容，并将第二响应内容反馈给应用客户端。这样，通常对第一响应内容进行更改并反馈的方式，可以实现对第一请求的灵活反馈。In specific implementation, when the request header information is response context information, for example, the page content update information carried in the request processing information can be used to update the page content in the response context information (for example, graying out, changing colors, etc.) , thereby obtaining the updated response context information. Based on the updated response context information, the second response content can be generated, and the second response content can be fed back to the application client. In this way, flexible feedback to the first request can be achieved by usually changing the content of the first response and providing feedback.

在另一种实施方式中，也可以不对第一响应内容进行更改，直接将其反馈给应用客户端。In another implementation manner, the first response content may be directly fed back to the application client without changing it.

在一种实施例中，在将第二响应内容反馈给应用客户端之后，还可以执行filter列表配置指示的response_end阶段，基于第一请求、第二请求、第一响应内容和第二响应内容中的至少一个，生成第一请求对应的日志信息，并保存该日志信息。或者，也可以执行response_end阶段，释放处理第一请求时所使用的计算资源。例如，释放目标服务器中的计算资源，释放功能网关中的计算资 源。In one embodiment, after the second response content is fed back to the application client, the response_end phase indicated by the filter list configuration may also be executed, based on the first request, the second request, the first response content and the second response content. At least one of, generates log information corresponding to the first request, and saves the log information. Alternatively, the response_end phase can also be executed to release the computing resources used when processing the first request. For example, release computing resources in the target server, release computing resources in the functional gateway source.

在一种实施例中，本公开实施例还提供了预先配置路由配置信息的方法，具体的，可以按照以下步骤实施：In one embodiment, the embodiment of the present disclosure also provides a method for pre-configuring routing configuration information. Specifically, it can be implemented according to the following steps:

步骤一、获取配置中心发送的序列化处理后的路由配置文件；其中，路由配置文件为配置中心在获取针对应用客户端对应的应用的路由配置信息后，对其序列化处理得到的文件。Step 1: Obtain the serialized routing configuration file sent by the configuration center; the routing configuration file is a file obtained by the configuration center after obtaining the routing configuration information for the application corresponding to the application client and serializing it.

这里，配置中心即控制面，用户可以在配置中心设置针对各种应用的路由配置信息。Here, the configuration center is the control plane, and users can set routing configuration information for various applications in the configuration center.

本步骤在具体实施时，配置中心在获取到用户配置针对应用客户端对应的应用的路由配置信息后，可以对该最新的路由配置信息进行序列化处理，将该最新的路由配置信息序列化处理为功能网关能够存储的路由配置文件。之后，配置中心可以将该路由配置文件发送至功能网关。During the specific implementation of this step, after obtaining the routing configuration information configured by the user for the application corresponding to the application client, the configuration center can serialize the latest routing configuration information and serialize the latest routing configuration information. It is the routing configuration file that the functional gateway can store. The configuration center can then send the routing configuration file to the functional gateway.

步骤二、对路由配置文件执行反序列化处理操作，得到还原后的路由配置信息，并利用路由配置信息替换历史路由配置信息。Step 2: Perform deserialization on the routing configuration file to obtain the restored routing configuration information, and use the routing configuration information to replace the historical routing configuration information.

这里，功能网关也称为数据面。历史路由配置信息可以为功能网关中已存储的路由配置信息。Here, the functional gateway is also called the data plane. Historical routing configuration information can be routing configuration information stored in the functional gateway.

具体实施时，功能网关可以对获取的路由配置文件执行反序列化处理操作，得到还原后的路由配置信息。之后，可以将路由配置信息以结构体的形式存储在功能网关中，以实现对历史路由配置信息的替换。During specific implementation, the function gateway can perform a deserialization operation on the obtained routing configuration file to obtain restored routing configuration information. Afterwards, the routing configuration information can be stored in the functional gateway in the form of a structure to replace historical routing configuration information.

具体的，功能网关可以获取结构体对应的目标指针地址，然后，利用原子操作指令，将已存储的历史路由配置信息对应的指针地址替换为目标指针地址，也即实现了利用最新的路由配置信息替换历史路由配置信息。。这样，在后续接收到新的请求后，可以利用目标指针地址指示的最新的路由配置信息进行路由匹配。Specifically, the function gateway can obtain the target pointer address corresponding to the structure, and then use atomic operation instructions to replace the pointer address corresponding to the stored historical routing configuration information with the target pointer address, that is, utilizing the latest routing configuration information. Replace historical routing configuration information. . In this way, after receiving a new request subsequently, the latest routing configuration information indicated by the target pointer address can be used for routing matching.

这里，针对将已存储的历史路由配置信息对应的指针地址替换为目标指针地址的步骤，如果功能网关中存在已接受但未处理完的请求，则此类型的请求仍需使用已存储的历史路由配置信息进行路由匹配。因此在具体实施时，可以在利用已存储的历史路由配置信息，完成对此类型的请求的路由匹配后，再将历史路由配置信息对应的指针地址替换为目标指针地址。Here, regarding the step of replacing the pointer address corresponding to the stored historical routing configuration information with the target pointer address, if there is a request that has been accepted but not processed in the functional gateway, this type of request still needs to use the stored historical routing Configuration information for route matching. Therefore, during specific implementation, you can use the stored historical routing configuration information to complete route matching for this type of request, and then replace the pointer address corresponding to the historical routing configuration information with the target pointer address.

此时，如果在确定了目标指针地址之后，在将历史路由配置信息对应的指 针地址替换为目标指针地址之前，接收到了新的请求，该新的请求也将使用目标指针地址对应的最新的路由配置信息进行路由匹配。At this time, if after determining the target pointer address, the pointer corresponding to the historical routing configuration information is Before the needle address is replaced with the target pointer address, a new request is received, and the new request will also use the latest routing configuration information corresponding to the target pointer address for routing matching.

这样，由于功能网关不需要重启，通过将路由配置信息存储在功能网关中的方式，可以实现对应用对应的路由配置信息的热更新，相比现有技术中需要重启应用才可以实现路由配置信息的更新而言，本公开实施例提供的配置路由配置信息的方式，提高了路由配置信息更新的及时性和便利性。In this way, since the functional gateway does not need to be restarted, by storing the routing configuration information in the functional gateway, hot update of the routing configuration information corresponding to the application can be achieved. Compared with the existing technology, which requires restarting the application, the routing configuration information can be realized. In terms of updating, the method of configuring routing configuration information provided by the embodiments of the present disclosure improves the timeliness and convenience of updating routing configuration information.

如图2所示，为本公开实施例提供的一种请求调度方法的具体实施流程图，可以包括以下步骤：As shown in Figure 2, a specific implementation flow chart of a request scheduling method provided by an embodiment of the present disclosure may include the following steps:

S205：根据目标上下文信息生成第二请求，并将第二请求发送至第一备用服务器。S205: Generate a second request according to the target context information, and send the second request to the first backup server.

这里，执行S205后，可以获取第一备用服务器对第二请求进行响应处理后反馈的响应内容。在得到第一备用服务器反馈的响应内容后，可以直接反馈给应用客户端，也可以执行S208，并将在执行S208后得到的响应内容反馈给客户端。Here, after executing S205, the response content fed back by the first backup server after processing the response to the second request can be obtained. After obtaining the response content fed back by the first backup server, it can be directly fed back to the application client, or S208 can be executed, and the response content obtained after executing S208 is fed back to the client.

S208：按照请求处理信息指示的、在第三处理阶段(response_header阶段)对应的内容更新信息，对第一响应内容中的响应头信息进行更改，得到第二响应内容。S208: According to the content update information corresponding to the third processing stage (response_header stage) indicated by the request processing information, change the response header information in the first response content to obtain the second response content.

这里，在确定第一响应内容中携带的状态码指示响应正常的情况下，可以 执行本步骤。response_header阶段对应的内容更新信息，即为请求处理信息中携带的内容更新信息。Here, when it is determined that the status code carried in the first response content indicates that the response is normal, you can Follow this step. The content update information corresponding to the response_header stage is the content update information carried in the request processing information.

若在执行完S205后执行本步骤，可以内容更新信息对第一备用服务器反馈的响应内容中的响应头信息进行更改，并基于更改后的响应头信息，生成第二响应内容。If this step is performed after S205 is performed, the response header information in the response content fed back by the first backup server can be changed with the content update information, and the second response content is generated based on the changed response header information.

S209：将第二响应内容作为第一请求的响应结果反馈给应用客户端。S209: Feed back the second response content to the application client as the response result of the first request.

S210：执行请求处理信息指示的第四处理阶段(response_end阶段)，基于第一请求、第二请求、第一响应内容和第二响应内容，生成第一请求对应的日志信息；和/或，释放处理第一请求时所使用的计算资源。S210: Execute the fourth processing stage (response_end stage) indicated by the request processing information, and generate log information corresponding to the first request based on the first request, the second request, the first response content and the second response content; and/or release The computing resources used to process the first request.
