node.js请求的时候出现错误socket hang up

node.js请求的时候出现错误socket hang up
我请求带 ip+port这种就会出错，直接请求就不会报错，下面是我的代码，
大家帮忙看下
比如访问http://192.168.1.157:8400/api/v2/login 这种就会报错
http://www.test.com/api/v2/login%E6%AD%A3%E5%B8%B8

_request (proxy, uReq, uRes) {
const u = url.parse(uReq.url)

const socksAgent = new socks.Agent({
  proxy,
  target: { host: u.host, port: u.port }
})

const options = {
  hostname: u.hostname,
  port: u.port || 80,
  path: u.path,
  method: u.method || 'get',
  headers: u.headers,
  agent: socksAgent
}

const pReq = http.request(options)
pReq.on('response', pRes => {
  pRes.pipe(uRes)
  uRes.writeHead(pRes.statusCode, pRes.headers)
  this.emit('request:success')
}).on('error', e => {
  uRes.writeHead(500)
  uRes.end('Connection  error\n'+e.message)
   this.emit('request:error', e)
})

uReq.pipe(pReq)

}
