小程序链接内网电脑
电脑端开TCP 端口号为60000的端口 ,server端口。小程序 可以连接
端口 ,但不能发数据?请问问什么?
var app = getApp(); var SocketTask = false ; var socketOpen = false ; var socketMsgQueue = [] Page({ data: { inputValue: '123' , returnValue: '1' , }, onLoad: function (options) { }, onReady: function () { wx.connectSocket({ url = "ws://172.20.20.21:60000" }) wx.onSocketOpen( function (res) { socketOpen = true ; for ( var i = 0; i < socketMsgQueue.length; i++) { sendSocketMessage(socketMsgQueue[i]) } socketMsgQueue = []; }) function sendSocketMessage(msg) { if (socketOpen) { wx.sendSocketMessage({ data: msg }); } else { socketMsgQueue.push(msg) } } } }) //通过 WebSocket 连接发送数据,需要先 wx.connectSocket,并在 wx.onSocketOpen 回调之后才能发送。 function sendSocketMessage(data) { console.log( '通过 WebSocket 连接发送数据' ) if (socketOpen) { SocketTask.send({ //data: JSON.stringify(data) data: data }, function (res) { console.log( '已发送' , res) }) } else { socketMsgQueue.push(msg) } } |
