如何在Python中进行异步gRPC调用？

pip install grpcio grpcio-tools

syntax = "proto3";

package example;

service ExampleService {
  rpc ExampleMethod (ExampleRequest) returns (ExampleResponse) {}
}

message ExampleRequest {
  string message = 1;
}

message ExampleResponse {
  string reply = 1;
}

python -m grpc_tools.protoc -I. --python_out=. --grpc_python_out=. example.proto

import asyncio
import grpc
import example_pb2
import example_pb2_grpc

async def make_grpc_call():
    channel = grpc.aio.insecure_channel('localhost:50051')
    stub = example_pb2_grpc.ExampleServiceStub(channel)
    request = example_pb2.ExampleRequest(message='Hello')
    response = await stub.ExampleMethod(request)
    print(response.reply)

if __name__ == '__main__':
    asyncio.run(make_grpc_call())
