Question

我用电子开发了一个应用程序。我将此应用程序用作文件传输服务。但是当我使用socket.io-stream时，会出现一些问题。

服务器端工作正常。它接受来自另一个的流快递项目。
在fs = this.electronService.remote.require('fs');中，我认为问题是“烟斗”，但我该怎么办？

请帮助我。

带有Express的服务器端代码

var express = require('express');  
var app = express();  
var server = require('http').createServer(app);  
var ios = require('socket.io')(server);
var ss=require('socket.io-stream');
var fs=require('fs');
var redisAdapter = require('socket.io-redis');
ios.adapter(redisAdapter({ host: '127.0.0.1', port: 6379 }));
var io = ios.of('/test');

app.use(express.static(__dirname + '/node_modules'));  
app.get('/', function(req, res,next) {  
  res.send('Hello 3000!');
});

io.on('connection', function(socket) {  
   let room=socket.handshake.query.room;
   socket.join(room);

   ss(socket).on('client2serverfile', function(stream) {
      stream.pipe(fs.createWriteStream('c:/temp/X1.txt'));
      stream.on('end',()=>{
         console.log('File saved'); 
      })
   });
});

server.listen(3000, () => console.log('Example app listening on port 3000!'))

电子和角度为5的客户端代码

import { Component,OnInit } from '@angular/core';
import {ElectronService} from 'ngx-electron';
import * as io from 'socket.io-client';
import * as ss from 'socket.io-stream';

@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})

export class AppComponent {
   constructor(private electronService: ElectronService){};
   socket = io('http://localhost:3000'+ '/test',{query:"room=myroom"});
   fs = this.electronService.remote.require('fs');

   streamTransfer(){//triger button
     let stream= ss.createStream();
     ss(this.socket).emit('client2serverfile',stream);
     this.electronService.fs.createReadStream('c:/temp/x2.txt').pipe(stream);
     stream.on('end',()=>{
        console.log('OK')
     })
   }
}

请忽略代码中的错别字。运行代码时，出现以下错误。

如何将socket.io-stream与electron.js一起使用？
