源代码位置

1. 下载官方示例

git clone git@github.com:grpc/grpc-node.git

• 复制examples\helloworld\static_codegendemo

2. 得到如下目录

• 安装项目依赖

npm i @grpc/grpc-js
npm i google-protobuf
npm i minimist

2.1 安装工具依赖

npm install -g grpc-tools

2.2 编译 .proto 文件

cd ./pb
grpc_tools_node_protoc.cmd --js_out=import_style=commonjs,binary:./ --grpc_out=grpc_js:./ helloworld.proto

• 这里根据官方给的grpc_tools_node_protoc --js_out=import_style=commonjs,binary:./ --grpc_out=grpc_js:./ helloworld.proto得不到helloworld_pb.js文件; 详情请看helloworld_pb.js file is not generated #2600

3. 修改官方示例

// greeter_server.js

  - server.addService(services.GreeterService, {sayHello: sayHello});
  + server.addService(services['helloworld.Greeter'], {sayHello: sayHello});

// greeter_client.js
- var client = new services.GreeterClient(target,
                                          grpc.credentials.createInsecure());

+ var GreeterClient = grpc.makeGenericClientConstructor(services['helloworld.Greeter']);

+ const client = new GreeterClient(target, grpc.credentials.createInsecure())

4.运行

node .\greeter_server.js
node .\greeter_client.js
