如何使用grpc的boringssl函数来处理nodejs程序

npm install @grpc/grpc-js @grpc/proto-loader

syntax = "proto3";

package hello;

service Greeter {
  rpc SayHello (HelloRequest) returns (HelloReply) {}
}

message HelloRequest {
  string name = 1;
}

message HelloReply {
  string message = 1;
}

protoc --js_out=import_style=commonjs,binary:. --grpc_out=grpc_js:. --plugin=protoc-gen-grpc=path/to/protoc-gen-grpc-js hello.proto

const grpc = require('@grpc/grpc-js');
const protoLoader = require('@grpc/proto-loader');
const path = require('path');

const PROTO_PATH = path.join(__dirname, 'hello.proto');
const packageDefinition = protoLoader.loadSync(PROTO_PATH, {
  keepCase: true,
  longs: String,
  enums: String,
  defaults: true,
  oneofs: true
});
const helloProto = grpc.loadPackageDefinition(packageDefinition).hello;

function sayHello(call, callback) {
  callback(null, { message: 'Hello ' + call.request.name });
}

function main() {
  const server = new grpc.Server();
  server.addService(helloProto.Greeter.service, { sayHello: sayHello });
  server.bindAsync('0.0.0.0:50051', grpc.ServerCredentials.createInsecure(), () => {
    server.start();
    console.log('Server running at http://0.0.0.0:50051');
  });
}

main();

const grpc = require('@grpc/grpc-js');

  const user = process.argv.length >= 3 ? process.argv[2] : 'world';
  client.sayHello({ name: user }, (err, response) => {
    console.log('Greeting:', response.message);

}

main();
