Electron中TCP Socket阻塞问题：是否源于渲染进程异常？

在Electron模板中使用TCP Socket时出现阻塞情况，怀疑该问题与Electron渲染进程有关。

Socket测试代码 #

var net = require('net')
const ctime = new Date().getTime()
console.log(ctime)
this.client = new net.Socket()
this.client = net.connect({ port: 29999, host: '127.0.0.1' }, function() {
  console.log('Connected:')
  console.log(' local= %s:%s', this.localAddress, this.localPort)
  console.log(' remote= %s:%s', this._remoteAddress, this._remoteAddress)
  this.setTimeout(500)
  this.setEncoding('utf8')
  this.on('data', function(data) {
    console.log(' From Server:' + data.toString())
    this.end()
  })
  this.on('end', function() {
    console.log('Client disconnection')
  })
  this.on('error', function(err) {
    console.log('Socket Error:' + JSON.stringify(err))
  })
  this.on('timeout', function() {
    console.log('Socket Timed Out')
  })
  this.on('close', function() {
    console.log('Socket Closed')
  })
})
console.log('连接成功')
this.client.write('aaa')

问题现象 #

1. 启动上述函数时，程序出现阻塞：
   

2. 当页面渲染一个表格时，Socket能成功连接并打印相关信息：
   

3. 清空页面后，使用以下仅含测试按钮的组件代码，点击测试按钮时程序仍然阻塞：

<template>
  <div>
    <el-button type="success" round @click="test">测试</el-button>
  </div>
</template>

<script>

var net = require('net')

export default {
  methods: {
    test() {

      const ctime = new Date().getTime()
      console.log(ctime)
      this.client = new net.Socket()
      this.client = net.connect({ port: 29999, host: '127.0.0.1' }, function() {
        console.log('Connected:')
        console.log(' local= %s:%s', this.localAddress, this.localPort)
        this.setTimeout(500)
        this.setEncoding('utf8')
        this.on('data', function(data) {
          console.log(' From Server:' + data.toString())
          this.end()
        })
        this.on('end', function() {
          console.log('Client disconnection')
        })
        this.on('error', function(err) {
          console.log('Socket Error:' + JSON.stringify(err))
        })
        this.on('timeout', function() {
          console.log('Socket Timed Out')
        })
        this.on('close', function() {
          console.log('Socket Closed')
        })
      })
      console.log('连接成功')
      this.client.write('aaa')
    }
  }
}
</script>
