采用aio的实现方式,只需要使用1.35.0版本及以上的grpcio库,在创建服务端的时候将grpc.server()改为aio.server(),服务启动的类方法采用async和await的方式即可完成。 注:服务端开启了aio的支持,是既可以支持阻塞式的客户端请求,也支持客户端非阻塞式请求的,所以对于旧版本客户端是直接兼容的。 客户端 服务端增加了...
async def main(): conn = grpc_client_connection(svc = "blue") stub = IamStub(conn) resp = await stub.WhoAmI(WhoAmIRequest()) print(resp) 其中服务名称为 。但是,如果我尝试连接到其他服务来请求如下数据:blue from alphausblue.connection.conn import grpc_client_connection ...
生成Python代码:使用grpc_tools.protoc编译Protobuf文件,生成Python代码。 实现服务:在Python中定义并实现服务类,使用async def定义异步方法。 启动服务器:创建并启动gRPC异步服务器。 实现客户端:定义并实现客户端类,使用异步方法调用服务。 示例代码: 定义Protobuf文件(greeter.proto): protobuf syntax = "proto3";...
