In this specification, after the proxy service is registered as a microservice consumer of the second microservice system, the proxy service may invoke microservice provided by a microservice provider in the second microservice system.
Continuing the example from the above example, referring to steps S2-S6 shown in fig. 4, after proxy service a1 is the microserver of microserver system SystemB, proxy service a1 may invoke the microserver provided by microserver P2 in microserver system SystemB.

In this specification, after receiving the call request, the proxy service acquires a call response corresponding to the call request from the second microservice system in response to the call request.
Continuing the example from the above example, referring to steps S5 to S6 shown in fig. 4, after receiving a call request that C1 wants to call a service interface corresponding to the P2 microservice, the proxy service a1 continues to call the microservice provided by the P2 corresponding to the call request from the microservice system SystemB; and acquiring a call response corresponding to the microservice provided by the P2.
