WeixinJSBridge.invoke 不走回调函数原因

不要直接去调用这个方法，通过demo的方式去调用

paymentWxMpPay({ orderId: res['data'].data }).then(value => {if (value['data'].status == 200) {let params = {"appId": value['data'].data.appId,     //公众号名称，由商户传入     "timeStamp": value['data'].data.timeStamp,         //时间戳，自1970年以来的秒数     "nonceStr": value['data'].data.nonceStr, //随机串     "package": value['data'].data.package,"signType": value['data'].data.signType,         //微信签名方式：     "paySign": value['data'].data.paySign //微信签名 }// 支持回调必要方法startif (typeof WeixinJSBridge == "undefined") {if (document.addEventListener) {document.addEventListener('WeixinJSBridgeReady', function () { this.onBridgeReady(params, res['data'].data); }, false);} else if (document['attachEvent']) {document['attachEvent']('WeixinJSBridgeReady', function () { this.onBridgeReady(params, res['data'].data); });document['attachEvent']('onWeixinJSBridgeReady', function () { this.onBridgeReady(params, res['data'].data); });}} else {this.onBridgeReady(params, res['data'].data);}} else {Taro.showToast({title: value['data'].message,icon: 'none',duration: 2000})}})

//微信公众号支付onBridgeReady(Data,id) {const _this = thisWeixinJSBridge.invoke('getBrandWCPayRequest',Data,function (res) {// Taro.showToast({title:JSON.stringify(res),icon:'none',duration:50000})if (res.err_msg == "get_brand_wcpay_request:ok") {_this.payResult({ payLogId: id })} else {Taro.showToast({title:'支付失败',icon:'none',duration:50000})// window.location.href = '&payStatus=cancel';}});}
