And the flow control rule storage service is configured by the current limiting control platform and is used for storing the current limiting rule configured by the current limiting control platform and waiting for the call of the current limiter.
In order to solve the technical problems described in the background art, the present invention provides the following groups of embodiments:
a first embodiment;
referring to fig. 1, there is provided a traffic access control method for a scenario of SAAS multi-tenant traffic access control, the method including the steps of:
s101, the flow restrictor receives access flow with an access request, the access flow is sent by a service calling end, hijacked by a flow agent and forwarded to the flow restrictor.
In this step, firstly, the service calling end initiates an access request to the multi-tenant management service, the flow proxy hijacks the access flow and forwards the access flow to the current limiter, and the current limiter judges whether to allow the access flow to access or not according to the current limiting rule.
S102, the current limiter judges whether the access request is available according to a current limiting rule in the current script file, and if the access request is unavailable, an unavailable result is returned to the flow proxy; if the flow agent is available, returning an available result to the flow agent; the current script file is the latest script file called by the current limiter from the flow control rule storage service, the flow control rule storage service is configured for the flow limiting control platform and is used for storing executable script files configured for the flow limiting control platform, and the script files contain corresponding flow limiting rules.
In this step, the current limiter judges the access request according to the current limiting rule in the current script file, and returns an unavailable result to the flow proxy if the current limiting rule does not allow the access request to pass; if the current flow limiting rule allows the access request to pass through, an available result is returned to the flow agent.
Referring to fig. 2, several sets of flow limiting rules are shown below:
the first one is: and matching the POST request of the/v 1/ratelimiit/test 2 interface under the http path, wherein the header of the http contains X-H3-Engineer code and the http request with the value of C000157 (tenant number) is matched, and a token bucket algorithm is adopted for limiting the correct matching, and the access frequency is limited to 2 times per second.
A second bar: and matching the HTTP requests of the/v 1/ratelimit/test3 interface under the http path, wherein the header of the http contains X-H3-Engineer code and the value of the HTTP requests needs to be C000175 (tenant number), and if the HTTP requests are matched correctly, limiting the access times to 1 time per second by adopting a sliding window algorithm.
And a third: and matching all the requests of the/v 1/ratelimit interface under the http path, and adopting a token bucket algorithm to limit the access times to 1 time per second if the requests are matched correctly.
In this implementation, the unavailable result is marked on the returned http status code, e.g., the returned 429 status code indicates that the request was denied. If no 429 status code is returned, the request is allowed.
In this embodiment, the traffic broker uses google open source component isio implementation, and within the isio, it uses Envoy (Envoy is an open source traffic control component and provides plug-in development) component to perform traffic brokering. The following provides a set of examples of the process of hijacking access traffic from the traffic broker to the restrictor until the processing restrictor returns the access result:
(1) the traffic broker hijacks the http request using the envoyFilter (the plug-in is loaded by the Envoy to realize hijacking the access traffic to the restrictor), wherein the EnvoyFilter internally configures the IP address and the port number of the restrictor.
(2) For a hijacked http request, it is forwarded to the restrictor.
(3) And obtaining a result returned by the current limiter, if the returned result is equal to 429, indicating that the request is rejected, directly returning 429 an error code to the service calling terminal, and not sending the request to the multi-tenant management service, otherwise, allowing the request, and enabling the access flow to enter the multi-tenant management service.
In this embodiment, the current script file in the current limiter is the latest script file stored in the called flow control rule storage service, and the current script file includes the corresponding current limiting rule. The flow control platform configures a flow control rule storage service first, and the flow control rule storage service is used for storing executable script files. As an optional implementation manner, the flow-limiting control platform converts a flow-limiting rule pre-configured according to an actual flow situation into a script file with a corresponding script language through a Freemarker, then stores the converted script file in a flow-control rule storage service, and waits for the invocation of a flow limiter; wherein freemaker is a tool that is based on template files and current limiting rules and used to generate output text (HTML, email, configuration files, source code, etc.). The current limiter calls the latest script file stored by the flow control rule storage service, and then the current limiting rule in the script file is used as the current limiting rule of the current limiter based on the language interpreter of the current limiter, so that the current flow control is realized.
In the method, a flow control platform first configures a flow control rule storage service capable of storing an executable script file, where the script file includes a flow limit rule configured by the flow control platform according to an actual situation, and a flow restrictor can call a latest script file from the flow control rule storage service at any time and perform flow control according to the flow limit rule. The method uses the script language to realize the flow control, does not need to be translated into various realization languages, reduces the maintenance cost, and can dynamically configure and update the script file by the flow limiting control platform, so that the flow control of the scene is more accurate; the method does not need to maintain various fluid controllers sdk, and can greatly reduce the pressure of developers.
It should be noted that, in the present embodiment and the subsequent embodiments, a scenario of SAAS multi-tenant traffic access control is taken as an example, but the method of the present embodiment is not only applicable to SAAS multi-tenant flow control management, but also applicable to flow control management of general services. Therefore, taking the scenario of SAAS multi-tenant traffic access control as an example, the scope of protection of the present application cannot be limited.
