把这段server的配置添加到Nginx的http段里,配置和启动好Nginx之后,然后把cal_client.py里的channel = grpc.insecure_channel('localhost:50051')一行的连接地址替换为Nginx提供的地址就可以了。执行结果是一样的,就不再做一遍了。 接着往下挖掘gRPC的HTTP2.0接口细节的话,可

import grpc from protos import hello_pb2, hello_pb2_grpc 主功能 继续添加一个run使用以下代码调用的新函数: : def run(): with grpc.insecure_channel('localhost:50051') as channel: stub = hello_pb2_grpc.GreeterStub(channel) response = stub.SayHello(hello_pb2.HelloRequest(name='John Doe', ...

import grpc 1. 接下来就是调用模块中的方法来进行grpc接口的连接、测试了。如果服务端起在本地的50051端口,完整实现的代码如下: import helloworld_pb2import helloworld_pb2_grpcimport grpcdef run(): # 连接 rpc 服务器 channel = grpc.insecure_channel('localhost:50051') # 调用 rpc 服务 stub = hellowo...

get_rpc_channel(host, port, is_aio) stub = xxxe_pb2_grpc.xxxStub(channel) return stub 可以看出,aio的客户端实现方式(grpc.aio.insecure_channel)也只比原来的方式(grpc.insecure_channel)多了一步获取aio的对象进行连接而已,这里做简单的案例采用未认证的insecure_channel方式,生产环境建议使用secure_...

recommendations_channel = grpc.insecure_channel("localhost:50051") 现在您想要连接到recommendations:50051。但是,您可以从环境变量中加载它,而不是再次对其进行硬编码。用以下两行替换上面的行: recommendations_host = os.getenv("RECOMMENDATIONS_HOST", "localhost") recommendations_channel = grpc.insecure_channel...
