生成到grpc的文件

服务端编写

客户端编写

源码

// Filename: lwz_model.proto
 
syntax="proto3";
package lwz_example;
service model{
    rpc lwz_show(lwz_Request) returns (lwz_Response){}
}
 
 
message lwz_Request {
    string index = 1;
    string name = 2;
    int64 age = 3;
}
 
message lwz_Response{
    string stu_class = 1;
    int64 grade = 2;
}

服务端

#!/usr/bin/env python
# coding:utf-8
import grpc
import time
from concurrent import futures
import lwz_model_pb2_grpc, lwz_model_pb2
 
_ONE_DAY_IN_SECONDS = 60 * 60 * 24
_HOST = 'localhost'
_PORT = '6060'
 
class model(lwz_model_pb2_grpc.modelServicer):
    #### 随意定义-封装好的函数 #####
    def serch_student_class(self, index):
        if index == '201801':
            student_class = '5'
            return student_class
 
    def serch_student_grade(self,name ,age):
        if name =='lwz' and age == 100:
            student_grade = 100
            return student_grade
 
    ##### 真正重要的-输出函数 #####
    def lwz_show(self, request, context):
        index = request.index
        name = request.name
        age = request.age

客户端

def run():
    conn = grpc.insecure_channel(_HOST + ':' + _PORT)

    response = client.lwz_show(lwz_model_pb2.lwz_Request(index = '201801',name = 'lwz',age = 100))
    print("received: " + response.stu_class)
    print("received: " + str(response.grade))
 
if __name__ == '__main__':
    run()
