Currently, when a service party provides a service to a user through a CDN, a fee needs to be delivered to the CDN service provider according to rules, but the cost of each service department on the CDN cannot be determined according to the actual usage of each service currently, which is not favorable for statistics and cost control.

In view of the foregoing problems, embodiments of the present application provide a cost query method for a CDN and a related device, and the following describes the embodiments of the present application in detail with reference to the accompanying drawings.

Referring to fig. 1a, fig. 1a is a schematic diagram illustrating an architecture of a fee inquiry system according to an embodiment of the present disclosure. As shown in fig. 1a, the fee inquiry system 10 includes a client device 101, a catalog generation server 102, a catalog acquisition server 103, a fee inquiry server 104, a first electronic device 105, and a second electronic device 106. The client device 101 is configured to send resource request information and display the obtained service resources, and the directory generation server 102 is configured to generate a new directory according to the resource request information from the client device, so that the client device 101 can initiate a request to a CDN service provider, that is, the first electronic device 105, according to address information in the generated directory, and the first electronic device 105 returns corresponding service resources to the client device 101 according to a resource acquisition request of the client device 101. When the service provider needs to perform CDN cost query, the cost query information may be sent to the cost query server 104 through the second electronic device 106, and the cost query server 104 determines the cost according to the directory in the directory acquisition server 103 and the log information in the first electronic device 105.

The catalog generation server 102, the catalog acquisition server 103, and the fee inquiry server may be located in the same server cluster, and the structures of these servers may be as shown in fig. 1b, where fig. 1b is a schematic structural diagram of a server provided in this embodiment of the present application. The server 110 comprises a processor 120 memory 130, a communication interface 140, and one or more programs 131, wherein the one or more programs 131 are stored in the memory 130 and configured to be executed by the application processor 120, and the one or more programs 131 comprise instructions for performing any of the steps of the method embodiments described below. In a specific implementation, the processor 120 is configured to perform any one of the steps performed by the electronic device in the method embodiments described below, and when performing data transmission such as sending, optionally invokes the communication interface 140 to complete the corresponding operation. Here, the configurations of the client apparatus 101, the first electronic apparatus 105, and the second electronic apparatus 106 may be the same as the configuration of the server 110.

Referring to fig. 1c, fig. 1c is a schematic diagram of a framework of a fee inquiry system according to an embodiment of the present disclosure. As shown, the fee inquiry system includes an access layer, a service layer, and an infrastructure layer. The access stratum includes an operations platform and a directory generation server, which may also be referred to as a cost-accounting Software Development Kit (SDK). The service layer comprises a directory acquisition server and a cost query server, wherein the directory acquisition server can also be called a CDN cost accounting server, and the cost query server can also be called a CDN cost synchronization server, and is used for providing the capacity of counting CDN cost of each dimension according to different services and different attributes, exposing a query interface outwards and querying related service parties. The base device layer comprises a database, a CDN server and a message queue server, wherein the CDN server is used for providing CDN service.

The directory generation server and the directory acquisition server may include multiple servers, and each of the directory generation server and the directory acquisition server may be deployed at a location of the CDN server to achieve global multi-activity, thereby ensuring high availability of services and security of privacy. The expense query server can be deployed at a preset address, and the availability of the interface is ensured by reading the slave node data of the databases of all the local machine rooms and using the fragmentation function of the databases. For example, as shown in fig. 1d, fig. 1d is a deployment architecture diagram of a fee inquiry system according to an embodiment of the present application. Fig. 1d includes three directory generation servers deployed at different locations, where the directory generation servers at address a and address B share the directory acquisition server and the database at address a, and address C includes a separate directory acquisition server and database, where the directory generation servers at address a and address B send generated addresses to the directory acquisition server a, the directory acquisition server a stores the acquired directory in the database 1A, the directory generation server at address C sends the generated directory to the directory acquisition server C and stores the generated directory in the database C through the directory acquisition server C, and the cost inquiry server is located at a specific address, which may be any one of address a, address B, or address C, or a new address. For example, the fee inquiry server in this example is located in address a, and through the database sharding function, the fee inquiry server obtains information such as directories from database shard 1A and database shard C, and then stores the processed and obtained data into data 2A.

Referring to fig. 2a, fig. 2a is a schematic flowchart illustrating a cost query method for a CDN according to an embodiment of the present disclosure. As shown in the figure, the cost query method for the CDN is applied to a cost query system, where the cost query system includes a directory generation server, a cost query server, a directory acquisition server, a client device, a first electronic device, and a second electronic device, and the method includes the following steps:

step 201, the catalog generation server obtains resource request information from the client device.

Wherein the resource request information includes a service type of the service resource requested by the client device. In a specific implementation, the client may send Resource request information to a Resource distribution server of the CDN service provider, and the Resource distribution server performs Resource information detection according to the Resource request information to obtain attribute information of the Resource information, such as information of a service type, an original Uniform Resource Locator (URL), a version, and the like. The resource distribution server transmits the attribute information to the directory generation server.

In one possible example, before the directory generation server obtains the resource request information from the client device, the method further includes: the directory generation server acquires attribute configuration information from the directory acquisition server; caching the attribute configuration information.

After the service provider accesses the directory generation server, the directory generation server first queries attribute-related configuration and caches the acquired service attribute configuration. Particularly, the directory generation server may obtain the information of the attribute-related configuration from the directory acquisition server, and when the directory acquisition server is started, the directory acquisition server may pull the attribute configuration configured in advance by the service personnel and cache the attribute configuration locally. For example, as shown in fig. 2b, fig. 2b is a timing chart for acquiring a configuration according to an embodiment of the present application. The charge inquiry system can also comprise a configuration center, service personnel configure the service attribute information in advance and store the service attribute information in the configuration center, so that the directory acquisition server can pull the service attribute configuration information of the configuration center when being started and load the service attribute configuration information into a local cache, and the directory generation server can acquire the service attribute configuration from the directory acquisition server and cache the service attribute configuration.

Therefore, in the embodiment, the directory generation server can acquire the service attribute configuration information in advance, so that the efficiency and the accuracy of directory generation are improved when the directory is generated according to the service type.

Step 202, the directory generation server generates identification information according to the service type;

step 203, the catalog generation server generates a catalog according to the resource request information and the identification information, wherein the catalog includes address information of the service resource.

Wherein the address information includes the identification information. That is, after the directory generation service acquires the resource request information, it generates a corresponding unique identifier according to the service type, and then generates a directory according to the identifier, so that the directories generated by the same resource request are the same, and the directory includes address information, that is, a URL, so that the address information also includes the identifier information corresponding to the service type, that is, the identifier information and the address information can be spliced to obtain a new URL with a service type attribute.

In one possible example, the generating the identification information by the directory generation server according to the service type includes: determining target configuration information from the attribute configuration information according to the service type; generating the identification information according to the target configuration information; the directory generation server generates a directory according to the resource request information and the identification information, and the directory generation method includes: acquiring an original catalog according to the resource request information; and generating the catalog according to the original catalog and the identification information.

Wherein, the original directory includes original address information of the service resource corresponding to the resource request information. The target configuration information includes service type information, so that the address information included in the newly generated directory may be obtained by concatenating the original address information and the identification information.

As can be seen, in this example, the directory is generated according to the identification information, so that when querying the CDN cost, a specific service type can be located.

In one possible example, after the catalog generation server generates the catalog according to the resource request information and the identification information, the method further includes: the directory generation server determining whether the directory has been cached; if not, the directory generation server sends the directory to the directory acquisition server and caches the directory.

For example, as shown in fig. 2c, fig. 2c is a sequence diagram of directory mapping provided in the embodiment of the present application. As shown in the figure, after the directory is generated, it may be determined whether the directory is cached locally, if so, it may be indicated that the directory has been reported to the directory retrieval server, and if the directory is not cached locally, it means that the directory has not been reported to the directory retrieval server, so that the directory needs to be reported, and after reporting, the directory is written into the local cache. The directory acquisition server also consumes the directory information from the message queue server.

Therefore, in this example, whether to report the directory to the directory acquisition server is determined according to whether the directory exists in the local cache, so that occupation of system resources can be reduced.

In one possible example, the fee inquiry system further includes a message queue server, and the directory generation server sends the directory to the directory acquisition server, including: sending a registration request to the message queue server; and after the registration is successful, the directory is sent to the message queue server, so that the directory acquisition server acquires the directory from the message queue server.

For example, as shown in fig. 2b, after the business party accesses the directory generation server, the business party further obtains a Message Queue (MQ) and registers the MQ producer, so that after the directory generation server generates a directory and locally caches the directory, the directory generation server may encapsulate the directory into MQ messages and send the MQ messages to the directory acquisition server. The directory acquisition server is used as a consumer of the MQ, the MQ message of the directory generation server can be read, and then the directory information is written into the database after the operations of parameter verification, structure conversion and the like are carried out.

Therefore, in the embodiment, the flexibility and the stability of the system can be improved by sending and acquiring the message through the message queue.

Step 204, the directory generation server sends the address information to the client device;

step 205, the client device sends a resource obtaining request to the first electronic device according to the address information;

step 206, the first electronic device sends the service resource to the client device according to the resource obtaining request, and generates a query log.

The first electronic device is an electronic device of the CDN service provider.

In a possible example, before the first electronic device sends the target resource to the client device according to the resource obtaining request, the method further includes: the client device sends the resource obtaining request to a target CDN server in the CDN servers; the target CDN server determines whether to cache the service resource according to the resource acquisition request; if yes, the target CDN server sends the service resource to the client equipment; if not, the target CDN server determines source returning information according to the resource acquisition request; the target CDN server deletes information related to the service type in the source returning information to obtain target source returning information; the target CDN server sends the back source information to a higher-level CDN service server, wherein the higher-level CDN server is a CDN server in the CDN servers; the target CDN server acquires the service resources from the upper CDN server; and the target CDN server sends the service resource to the client equipment.

The target CDN server is used for providing CDN service, each CDN server can be located in different places, when the client device requests resources through the CDN, resource request information can be sent to the CDN server located at the same address as the client device, and if corresponding service resources are cached in the target CDN server, the service resources can be returned to the client device. If the local cache does not store the corresponding service resource, the resource is requested from a higher-level CDN server of the target CDN server, namely, the resource is returned to the source. The target CDN server may be a server at a primary node, and the upper CDN server may be a server at a secondary node or a source station server. When the CDN returns to the source, the directory encapsulated by the SDK is removed, that is, the directory when returning to the source does not include information related to the service attribute, so that transparent operation on the service party can be implemented.

Therefore, in this example, the CDN leaves the extra directory when returning to the source, and when the client device accesses the resource, the CDN leaves the spliced extra directory to take the actual path of the resource, so that the service side does not perceive it.

Step 207, the second electronic device sends the fee inquiry information to the fee inquiry server.

The query information includes a target service type, and the second electronic device is an electronic device of a service provider. The query information may also include a client device-defined query dimension, which may include time period-based CDN cost statistics, time period-based or domain name-based CDN traffic or broadband usage statistics, and so on. That is, all resources may be service-divided, and the capability of querying CDN traffic or cost according to a domain name is provided, and for an access cost accounting SDK, that is, a service party of a directory generation server, each service party is also supported to perform CDN traffic and cost query by customizing a query dimension.

Step 208, the expense query server determines a target directory from the directory acquisition server according to the target service type;

step 209, the fee inquiry server determines target identification information according to the service type;

step 210, the fee inquiry server obtains at least one target inquiry log from the first electronic device according to the fee inquiry information and the target identification information;

step 211, the fee inquiry server determines a target fee corresponding to the target service type according to the target directory and the at least one target inquiry log;

step 212, the fee inquiry server sends the target fee to the second electronic device.

The first electronic device records relevant logs each time the resource of the client device requests, and the logs can also carry corresponding identification information, so that the cost query server obtains the catalogue stored by the server according to the logs and the catalogue provided by the first electronic device to perform cost query, and the CDN cost of the daily active catalogue can be pulled to provide CDN data query capability for visual display.

In this example, the directory generation server generates identification information according to the resource request information of the client, then generates a directory according to the resource request information and the identification information, and then sends the address information in the directory to the client, so that the client can send a resource acquisition request to the first electronic device according to the address information, so that the first electronic device generates log information according to the resource acquisition request, so that a service provider can determine the cost of each service according to the log information and the directory when querying the CDN cost through the cost query server, so that the CDN cost can be distributed to each service department according to the use condition, and the service provider can perform cost control and service planning conveniently.

Referring to fig. 3, fig. 3 is a schematic flowchart of another fee query method for a CDN according to an embodiment of the present disclosure, where as shown in the figure, the fee query method for a CDN is applied to a directory generation server of a fee query system, where the fee query system includes the directory generation server, the fee query server, a client device, and a first electronic device, the method includes the following steps:

s301, acquiring resource request information, wherein the resource request information comprises the service type of the service resource requested by the client equipment;

s302, generating identification information according to the service type;

s303, generating a directory according to the resource request information and the identification information, wherein the directory comprises address information of the service resource, and the address information comprises the identification information;

s304, send the address information to the client device, where the address information is used to indicate a resource obtaining request of the client device for the first electronic device, the resource obtaining request is used to indicate a query log of the first electronic device, the query log includes the identification information, the directory and the query log are used to jointly indicate the cost in the cost query server, and the first electronic device is an electronic device of a CDN service provider.

In one possible example, the fee inquiry system further includes a catalog retrieval server, and before retrieving the resource request information, the method further includes: acquiring attribute configuration information from the directory acquisition server; caching the attribute configuration information; the generating of the identification information according to the service type includes: determining target configuration information from the attribute configuration information according to the service type; generating the identification information according to the target configuration information; the generating a directory according to the resource request information and the identification information includes: acquiring an original catalog according to the resource request information; and generating the catalog according to the original catalog and the identification information.

Therefore, in this example, the directory generation server caches the configuration information in advance, so that after the resource request information is obtained, the identification information can be quickly generated according to the configuration information, and a new directory is generated according to the identification information and the original directory corresponding to the resource. Therefore, the efficiency of generating the directory can be improved, and when subsequent client equipment uses the address information in the directory to acquire resources, the log information generated by the first electronic equipment can include attribute information related to the service type, so that the subsequent fee inquiry according to the service type is facilitated.

In one possible example, after the generating the directory according to the original directory and the identification information, the method further includes: determining whether the directory has been cached; if not, the directory is sent to the directory acquisition server, and the directory is cached.

Therefore, if the newly generated directory is cached, the directory is not sent to the directory acquisition server any more, and system resources can be saved.
