方法2

onLoad() {const socketTask = uni.connectSocket({url: 'ws://127.0.0.1:8000/ws/stat/realTimeStat/',success: (res) => {console.log('connect success', res);}});socketTask.onOpen(function (res) {console.log('WebSocket连接已打开！');socketTask.send({data: JSON.stringify({'username': 'realTimeStat', 'msg': 'stat'}),success: (res) => {console.log('send success', res);}});});socketTask.onMessage(function (res) {console.log('收到服务器内容：' + res.data);})socketTask.onError(function (res) {console.log('WebSocket连接打开失败，请检查！');});socketTask.onClose(function (res) {console.log('WebSocket 已关闭！');});},
