Claims (10)
1. A method of flow control, the method comprising:
acquiring a service processing request comprising an authentication token, wherein the authentication token comprises at least one of user information and historical access times, and adding the authentication token into a preset user grade list according to the historical access times;
analyzing the service processing request to obtain a service interface of the micro service node;
when the resource usage amount of the service processing request is larger than a first current limiting threshold, receiving a user grade list and an interface grade list returned by the service interface to a local cache, wherein the interface grade list is determined according to the resource usage data parameters of each service interface in all preset micro service nodes;
and if the user information in the service processing request is matched with the user grade list, the service interface is matched with the interface grade list, and the service processing request is executed.
2. The method according to claim 1, wherein the method further comprises:
when the resource usage amount of the service processing request is larger than a second current limiting threshold, the service interface intercepts the service processing request and returns current limiting prompt information to the client.
3. The method according to claim 1, wherein the obtaining the interface class list includes:
calculating the interface weight of the service interface according to the resource use parameters of the micro service node and the service interface;
and sequencing the service interfaces according to the interface weights to obtain the interface grade list.
4. The method according to claim 1, wherein the method further comprises:
acquiring user information according to the authentication token, and acquiring access right information of a user through the user information, wherein the access right information comprises an interface address list which can be accessed by the user;
and if the service interface in the service processing request is not in the interface address list, the service interface intercepts the service processing request.
5. The method of claim 2, wherein the first current limit threshold and the second current limit threshold are determined based on a resource usage parameter of the serving node.
6. A flow control device, the device comprising:
the generation module is used for acquiring a service processing request comprising an authentication token, wherein the authentication token comprises at least one of user information and historical access times, and the authentication token is added into a preset user grade list according to the historical access times;
the analysis module is used for analyzing the service processing request to obtain a service interface of the micro service node;
the judging module is used for receiving a user grade list and an interface grade list returned by the service interface to a local cache when the resource usage amount of the service processing request is larger than a first current limiting threshold, wherein the interface grade list is determined according to the resource usage data parameters of each service interface in all preset micro service nodes;
and the matching module is used for executing the service processing request if the user information in the service processing request is matched with the user grade list and the service interface is matched with the interface grade list.
7. The apparatus of claim 6, wherein the apparatus further comprises:
and the interception module is used for intercepting the service processing request by the service interface and returning the flow limiting prompt information to the client when the resource usage amount of the service processing request is larger than a second flow limiting threshold.
8. A computer device comprising a memory and a processor, the memory storing a computer program, characterized in that the processor implements the steps of the flow control method of any one of claims 1 to 5 when the computer program is executed.
9. A computer readable storage medium having stored thereon a computer program, characterized in that the computer program, when executed by a processor, implements the steps of the flow control method of any of claims 1 to 5.
10. A computer program product comprising a computer program, characterized in that the computer program, when executed by a processor, implements the steps of the flow control method according to any one of claims 1 to 5.
