小程序

onLoad: function () {
    console.log('开始');
    var that = this
    var url = 'ws://127.0.0.1:9501';
    wx.connectSocket({
      url: url,
    });
    wx.onSocketMessage((res) => {
      console.log(res)
      var text = res.data + "\n"; //通过\n实现换行再重新赋值

      wx.showModal({
        title:'消息提示',
        content:text,
        success:function(res){

        }
      })
    })
  }
