Fig. 1 schematically illustrates an application scenario of an embodiment of the present disclosure. As shown in fig. 1, an internet service provider 101 may provide various service interfaces for an internet service user 102. The internet service user 102 requests one or more service interfaces from the internet service provider 101 to obtain the required service according to his actual needs. The internet service provider 101 may provide a desired service to a plurality of internet service consumers 102. In an embodiment of the present disclosure, an internet service provider 101 interacts with an internet service consumer 102 via an internet service gateway 103. According to an embodiment of the present disclosure, the internet service user 102 transmits a request for a web service to the internet service gateway 103, and the internet service gateway 103 obtains response data from at least one service interface of the internet service provider 101 according to the received request and provides the corresponding web service to the internet service user 102 based on the obtained response data.
Fig. 2 schematically shows a flow chart of a method 200 of providing network services according to an embodiment of the present disclosure. As shown in fig. 2, the method 200 for providing network services includes the following steps:
in step S210, a request for a network service is received.
In step S220, a plurality of service interfaces for providing the network service are determined according to the request.
In step S230, dependencies between the plurality of service interfaces are determined.
In step S240, an access priority of each of the plurality of service interfaces is determined according to the dependency relationship.
In step S250, a plurality of service interfaces are accessed to provide a network service according to the access priority.
Specifically, in step S210, information about the requested network service or related service interface information may be included in the request for the network service. Different network services may be provided based on a received request for a network service.
Next, in step S220, after receiving the request for the network service, a plurality of service interfaces for providing the network service are determined according to information included in the request for the network service. The service interface for providing the network service may be one service interface or a plurality of service interfaces. The disclosed embodiments are generally directed to scenarios in which network services are provided through multiple service interfaces. According to an embodiment, a plurality of service interfaces for providing a network service may be determined based on whether data transmission is performed between each other in providing the network service.
Next, in step S230, determining the dependency relationship between the plurality of service interfaces includes determining a specific data transmission relationship between the service interfaces. According to an embodiment, the specific data transmission relationship between the service interfaces may include which service interfaces need to receive data from and output data to which service interfaces in the plurality of service interfaces in the process of providing the network service.
Next, in step S240, a data source required by the service interface to provide a service may be determined according to the dependency relationship between the service interfaces, and therefore, at least one service interface of the plurality of service interfaces providing the data source for the service interface needs to be accessed to obtain required data before the service interface provides the service, and therefore, the access priority of the at least one service interface providing the required data for the service interface is higher than the access priority of the service interface.
Next, in step S250, accessing the plurality of service interfaces according to the access priority may include sequentially accessing the service interfaces and concurrently accessing the service interfaces. According to the embodiment, the service interfaces with the dependency relationship are accessed according to the determined access priority sequence, and the service interfaces with the same access priority are accessed in parallel under the condition that the requirement of the access priority is met.
Conventional internet service gateways simply aggregate the individual service interfaces used to provide web services. When different service interfaces are requested, only sequential requests can be made. The access mode not only has complex interface access, but also has low access efficiency. Especially for large systems with large network delay, such as Internet Data Center (IDC), the user experience of Internet service users is seriously affected by the low access speed caused by sequentially accessing each Data interface.
According to the embodiment of the disclosure, the access priority of the service interfaces is determined according to the dependency relationship between the service interfaces, and the service interfaces are accessed sequentially or parallelly according to the access priority, so that the access capability of the service interfaces is improved. The method for providing the network service can solve the problem that the sequential access throughput cannot be improved and broken through due to network delay and network faults, so that the sequential access throughput of the whole system is not influenced by IDC and network topology, the utilization rate of the system to resources is greatly improved, and meanwhile, the network communication cost is effectively reduced.
In an embodiment of the present disclosure, for each of a plurality of service interfaces as a target service interface, a dependency relationship between the plurality of service interfaces is determined according to a data transmission direction between the target service interface and other service interfaces of the plurality of service interfaces. Fig. 3 schematically illustrates a process of determining a dependency relationship between a plurality of service interfaces according to an embodiment of the present disclosure, which is described below in conjunction with fig. 3.
As shown in fig. 3, with a service interface B as a target service interface, the relationship between the service interface B and other service interfaces includes: a service interface that provides data to service interface B, such as service interface a shown in fig. 3, and a service interface that receives data from service interface B, such as service interface C in fig. 3.
It should be noted that the service interface B may only provide data to other service interfaces, and not receive data from any other service interface. The example shown in fig. 3 illustrates the complete relationship between service interface B and service interface a and service interface C for ease of illustration only.
As shown in fig. 3, the dotted lines above the service interface a, the service interface B, and the service interface C indicate the data transmission direction between the service interface a, the service interface B, and the service interface C, and the dotted lines between the service interface a, the service interface B, and the service interface C indicate the data transmission direction between the service interfaces. Between the service interface A and the service interface B, data is transmitted from the service interface A to the service interface B, and the service interface (service interface A) providing data to the target service interface (service interface B) is determined as a superior service interface of the target service interface. Between the service interface B and the service interface C, data is transferred from the service interface B to the service interface C, and the service interface (service interface C) that receives data from the target service interface (service interface B) is determined as a service interface subordinate to the target service interface.
It is easily understood that the service interface B may not only receive data from one service interface, but also may output data to one service interface only. In the case where data is provided to the service interface B by a plurality of service interfaces, all the service interfaces providing data are determined as upper-level service interfaces of the service interface B. In a case where the service interface B outputs data to a plurality of service interfaces, all service interfaces that receive data are determined as lower-level service interfaces of the service interface B.
According to an embodiment of the present disclosure, the above-described operation may be performed for each of the plurality of service interfaces so as to determine an upper level service interface and a lower level service interface of each of the plurality of service interfaces, thereby determining a dependency relationship between the plurality of service interfaces.
In an embodiment of the present disclosure, an access priority of an upper level service interface of a target service interface is determined to be higher than an access priority of the target service interface, and an access priority of a lower level service interface of the target service interface is determined to be lower than the access priority of the target service interface.
The service interface a, the service interface B and the service interface C shown in fig. 3 are still taken as examples. Service interface a is a superior service interface to service interface B, and thus the access priority of service interface a is higher than that of service interface B. Service interface C is a lower-level service interface of service interface B, and thus the access priority of service interface C is lower than that of service interface B.
According to the embodiment, when the service interface A and the service interface B are accessed, the service interface A needs to be accessed first, and after the service interface A is accessed, the service interface B needs to be accessed. If service interface B has two or more superior service interfaces, then access to all superior service interfaces needs to be completed before access to service interface B. According to the embodiment, when accessing the service interface B and the service interface C, the service interface B needs to be accessed first, and after the access to the service interface B is completed, the service interface C needs to be accessed. If the service interface B has two or more lower level service interfaces, access to all the lower level service interfaces needs to be performed after access to the service interface B.
Further, in the embodiment of the present disclosure, a target service interface having no superior service interface is determined to have the highest priority. If the target service interface does not have the upper service interface, the target service interface does not need to wait for access after the access of other service interfaces is completed, namely, the target service interface can be accessed before the other service interfaces are accessed.
Further, in the embodiment of the present disclosure, a target service interface without any upper service interface and lower service interface is determined to have an arbitrary priority. And no dependency relationship exists between the target service interface without any upper service interface and lower service interface and other service interfaces. The access of the target service interface is not restricted by other service interfaces and has no influence on other service interfaces. Thus, such service interfaces can be accessed at any access phase. According to an embodiment, the access order of such service interfaces may be set at a certain access phase, for example, an access to a service interface with an arbitrary priority is set at a phase of accessing a service interface with the highest priority. According to the embodiment, according to the determined priorities of the plurality of service interfaces, the access to the service interface with any priority can be set at the stage where the service interfaces accessed at the same time are the least.
Further, in the embodiment of the present disclosure, in a case that a plurality of upper service interfaces of a target service interface have different access priorities, an upper service interface with a lowest access priority among the plurality of upper service interfaces is determined, and the access priority of the target service interface is determined to be lower than that of the upper service interface. Fig. 4 schematically shows the above-described process of determining the access priority of a service interface, which is described below in conjunction with fig. 4.
As shown in fig. 4, service interface a is an upper level service interface of service interface B, service interface B and service interface D are upper level service interfaces of service interface C, and wherein service interface a and service interface D do not have an upper level service interface. The case where the access priority of the service interface is determined for service interface B is: service interface a needs to be accessed before service interface B and service interface B needs to be accessed before service interface C. The case where the access priority of the service interface is determined for service interface C is: service interface B and service interface D need to be accessed before service interface C. Next, the access priorities of the service interface a, the service interface B, the service interface C, and the service interface D are jointly determined. Since service interface a and service interface D do not have an upper level service interface, i.e., service interface a and service interface D have the same highest access priority, service interface a and service interface D can be accessed first and in parallel. Service interface B may be accessed after access to service interface a is completed, according to the order of access priority. After access to service interface D is completed, service interface C may be accessed. However, since the service interface B is simultaneously an upper-level service interface of the service interface C, the service interface B and the service interface C cannot be accessed in parallel. This situation can be determined from a plurality of upper level service interfaces of the service interface C. Service interface B and service interface D are both superior service interfaces to service interface C, and service interface D has the highest access priority, referred to herein as the first access priority. And service interface B acts as a lower level service interface with service interface a having the highest access priority, having the next highest access priority, referred to herein as the second access priority. That is, upper service interfaces B and D of target service interface C have different access priorities. According to an embodiment, a service interface with a low access priority, i.e. a service interface B with a second access priority, among the upper service interfaces B and D is first determined, and then the target service interface C is determined to have a lower priority than the service interface B, e.g. the target service interface C is determined to have a third access priority.
In embodiments of the present disclosure, new service interfaces may be generated for different requests for network services, respectively, e.g., a configuration service interface for receiving requests is created prior to receiving requests for network services. The configuration service interface masks the service interfaces (also referred to as internal service interfaces) used to provide network services. When the internet service user requests the network service, the internet service user only needs to send a request to the configuration service interface, and does not need to separately request each internal service interface.
Fig. 5 schematically shows a block diagram of a configuration service interface according to another embodiment of the present disclosure.
As shown in fig. 5, the configuration service interface mainly includes a processing entity 501 for processing the operation of the configuration service interface to implement the configuration service interface function. The processing entity 501 comprises information 502 of the configuration service interface itself and a list 503 of plug-ins on which the configuration service interface is mounted. In embodiments of the present disclosure, configuring the service interface may orchestrate access to the internal service interface according to requests for network services to provide network services to internet service consumers.
According to an embodiment, the orchestration of access to the internal service interface is achieved through a plug-in. As shown in fig. 5, a plurality of plug-ins such as plug-in 1, plug-in 2, plug-in 3, and the like are included in the plug-in list 503. Each plug-in may implement different functions. According to an embodiment, the plug-in may implement at least one of the three methods before, access, and after, respectively. The method before is executed before requesting the internal service interface, and is used for judging whether to access the service interface. For example, a determination of whether to initiate access to a service interface may be based on whether the required data is received. The method access is used to access the service interface. The method after completes the access to the service interface, is used for interpreting the returned data result and storing the data result for the service interface of the lower level to use.
According to an embodiment, the configuration service interface may obtain information of a plurality of internal service interfaces related to providing the network service from a superior configuration center. As shown in fig. 5, when a service is initialized, the initialization plug-in init issued from the upper-level configuration center is used to obtain the global service interface list and the specific configuration information of each service interface in the multiple internal service interfaces. According to the embodiment, when the internal service interface is changed, the configuration service interface can also obtain the information of the internal service interface after the change from the upper-level configuration center. As shown in fig. 5, after a new internal service interface is added or configuration information of an original internal service interface is updated, configuration information of the newly added internal service interface is added or configuration information of the original internal service interface is updated through a plug-in onChange.
The configuration service interface pair according to the embodiment of the disclosure can determine the access priority of each internal service interface based on the dependency relationship among the internal service interfaces, and access the internal service interfaces based on the access priority sequence or in parallel, thereby improving the access speed of the internal service interfaces.
The following describes a process of determining an access priority of each of the plurality of service interfaces according to a dependency relationship between the plurality of service interfaces and accessing the plurality of service interfaces according to the access priority to provide a requested service, in conjunction with an example of pulling a product review list.
The following is an example of a pull item review list service for providing a list of displayed item reviews to users who purchase items. In this case, a request for a service of obtaining a product review list issued by a user may be received through the configuration service interface. In this example, the configuration between the plurality of service interfaces for providing the network service is as follows:
as can be seen from the above dependency relationship, the service interfaces related to the pulled commodity comment list service include 12 service interfaces, which are a1, a2, A3, a4, a5, A6, a7, A8, a9, a10, a11, and a 12. Among the above service interfaces, the service interfaces a1, a2, A3, a4, a5, a6, and a7 provide data for them independently of other service interfaces, that is, these 7 service interfaces do not have a superior service interface. The service interfaces A8, A9, A10, A11 and A12 have dependency relationships with other service interfaces, and the upper service interface and the lower service interface of each service interface can be determined according to the dependency relationship list.
For example, for service interface A8, it relies on service interfaces a1, a2, A3, and a4 to provide data for it, and thus service interfaces a1, a2, A3, and a4 are superior service interfaces to service interface A8. Meanwhile, the service interface A8 also exists in the dependency list of the service interfaces a9, a10 and a11, i.e. the service interface A8 needs to provide data for the service interfaces a9, a10 and a11, and thus the service interfaces a9, a10 and a11 are subordinate service interfaces of the service interface A8. A hierarchy of access priorities as shown in fig. 6 may be established based on the resulting dependencies between the plurality of service interfaces.
FIG. 6 is a diagram schematically illustrating a hierarchy of access priorities among a plurality of service interfaces according to an embodiment of the present disclosure. As shown in fig. 6, it may be determined that the service interfaces a1, a2, A3, a4, a5, a6, and a7 have the highest access priority, determined as the first access priority. Service interfaces a1, a2, A3, a4, a5, a6, and a7 may be accessed in parallel in the first stage. Next, the service interface A8, which is a lower-level service interface of the service interfaces a1, a2, A3, and a4, has the next highest access priority lower than the highest access priority, and is determined as the second access priority. The A8 may be accessed in the second phase after completing access to the service interfaces a1, a2, A3, and a 4. It should be noted here that although the service interfaces a9, a10, and a11, which are lower-level service interfaces of the service interfaces a5 and A6, should have the second access priority before being adjusted, since the upper-level service interface A8, which is also the service interfaces a9, a10, and a11, is the second access priority, the access priorities of the service interfaces a9, a10, and a11 are adjusted to be lower than the access priority of the service interface A8, and determined as the third access priority. I.e. in parallel access to the service interfaces a9, a10 and a11 in the third phase. Finally, service interface a12 is determined to be the fourth access priority and accesses service interface a12 in the fourth phase. In addition, the service interface a7 is a service interface with an arbitrary priority, which is incorporated in the first-phase access here.
In a conventional internet service gateway, it is necessary to sequentially access each service interface. For the 12 service interfaces in this example, each service interface needs to be requested individually in sequence, and the access efficiency is very low, thereby resulting in a low speed of providing network services. According to the method disclosed by the embodiment of the disclosure, access to 12 service interfaces is completed only by four access stages, and the access time is only 1/3 of the original access time, so that the access efficiency is greatly improved, and better service experience can be provided for users.
