return true, so the filter will take effect for all requests. In practice we can use this function to specify the effective range of the filter.Run: The specific logic of the filter. Here we use Ctx.setsendzuulresponse (false) to make Zuul filter the request, do not route it, and then set its return error code via CTX.SETRESPONSESTATUSCODE (401). Of course, we can also further optimize our return, for example, by Ctx.setresponsebody (body) to return the body content to edit and so on.After impl

I. Background Under the microservices architecture, our systems are split into multiple, single-duty microservices based on business. Each service has its own set of APIs to provide to other service calls, so how to ensure security. It is not that you want to invoke the call, we must have the authentication mechanism, is the request from our internal service, we can call our interface. Note that we are tal
