python3 grpc client 调用go grpc server的一种方式

第一步：安装依赖包

googleapis-common-protos==1.54.0
grpcio==1.42.0
grpcio-tools==1.42.0
protobuf==3.19.1
six==1.16.0

pip3.9 install grpcio  
pip3.9 install grpcio-tools
pip install googleapis-common-protos

第二步：写client

# coding=utf-8

ixxxort json



ixxxort grpc



from x'x'x ixxxort xxx_pb2_grpc, xxx_pb2




def run():

# 连接rpc服务器,insecure(不安全的)

"""

'xxx-xxx-grpc.xxx.test:xxx' 为服务端起的端口

"""

channel = grpc.insecure_channel('xxx-xxx-grpc.xxx.test:xxx')



# 调用rpc服务

"""

SecurityStub就是生成的xxx_pb2_grpc.py中的类class SecurityStub(object)，

而Security就是grpc协议文档xxx.proto中的service Security，然后拼接成SecurityStub



stub.xxx就是xxx.proto中的rpc xxx，

xxx_pb2.RequestSecurity就是 rpc xxx(RequestSecurity)中的请求"RequestSecurity"，

参数就是app_id=12345678就是 uint32 app_id = 1 定义的参数名app_id，



response获取响应的结果 xxx.proto的message ResponseSecurity

"""



stub = xxx_pb2_grpc.SecurityStub(channel)

request_data = xxx_pb2.RequestSecurity(xxx =12345678, xxx ="小米")

print(type(request_data))

print(request_data)

response = stub.xxx(request_data)

print(type(response))

print(response)

print(response.trace_id)

res = response.res

print(type(res))

print(res)

print(res[3].words)

print(res[2].words)

for k in response.res:

print(k)

print(type(k))

print(response.res[k])




if __name__ == '__main__':

run()

第三步：右键run client
