我试图测试我的grpc客户端连接使用下面的代码。我有。net核心grpc服务器和使用节点js grpc客户端连接。但得到“未能连接到所有地址”错误。但无法连接。net grpc服务器到。net grpc客户端。任何帮助非常感谢。
不确定IM是否丢失了下面grpc客户端代码中的任何内容。

'use strict';
//Same as the other projects we import fs for reading documents, in this case employees.js json
const fs = require('fs');

//Importing GRPC and the proto loader
const grpc = require('grpc');
const loader = require('@grpc/proto-loader');


//reads the proto
const packageDefinition = loader.loadSync('Repository.proto', {
  keepCase: false,
  longs: String,
  enums: String, 
  defaults: true,
  oneofs: true
});


//Loads the proto file to be used in constant pkg
const pkg = grpc.loadPackageDefinition(packageDefinition);

//Creates server
const PORT = 5001;

//console.log(pkg);

const client = new pkg.repository.Repository('localhost:5001', grpc.credentials.createInsecure());

 client.GetUpdates({}, function (err, response) {
    console.log("----Response error----");
    if (err) {
    
      console.log(err);
  } else {
      console.log(response);
  }
});

我得到下面的错误:

{ Error: 14 UNAVAILABLE: failed to connect to all addresses

  code: 14,
  metadata: Metadata { _internal_repr: {}, flags: 0 },
  details: 'failed to connect to all addresses' }

有人能帮我解决这个问题吗?

当我尝试按照官方文档中的gRPCnodejs教程学习时,遇到了同样的问题
根本原因(对我而言):端口50051是从主文档使用的默认端口,当我检查我的笔记本电脑上正在使用的端口列表时,转出端口50051由“NVIDIA Web helperiderexe”使用。
我是如何发现这一点的:我尝试将端口稍微更改为50052,并将错误记录到console.log中,结果显示为预期的
