备注： 在外链中，不能直接调起小程序原生客服（wx.openCustomerServiceChat）。

解决方法： 小程序里新增一个原生的过渡页面。外链跳转到过渡页面，在过渡页面添加点击事件，打开原生客服

在外链中劫持跳转，并跳转到原生的小程序页面

// 检测是否是微信环境var isWeChat = /micromessenger/i.test(navigator.userAgent);if (isWeChat && qywx_company_id) {console.log("当前是微信环境");jWeixin.miniProgram.navigateTo({url: "/pageE/transitionPage/transitionPage?corpId="+qywx_company_id+"&extInfoUrl="+data_info.cs_link})} else {console.log("当前不是微信环境");window.location.href = data_info.cs_link}

当外链打开过渡页面时，注意过渡页面的生命周期执行顺序，

created() {setTimeout(() => {// 打开微信客服// #ifdef MPif (this.$Route.query.corpId || this.$Route.query.extInfoUrl) {this.goChat()}// #endif}, 0)},

// 企业微信idgetQywxCs() {let _this = thisreturn new Promise((resolve, reject) => {this.$api.buy.getQywxCs().then(res => {if (res.code == 0) {this.qywx_company_id = res.data.qywx_company_idresolve(res.data)}})})},// 去客服goChat() {let _this = thisuni.showModal({title: '微信客服',content: '您即将进入客服对话框。',complete(res) {if (res.confirm) {if (!_this.$Route.query.corpId && !_this.qywx_company_id) {_this.getQywxCs().then((res) => {wx.openCustomerServiceChat({extInfo: {url: _this.$Route.query.extInfoUrl},corpId: res.qywx_company_id,success(res) {console.log(res, 'success');},fail(err) {console.log(err, 'err');},complete(res) {setTimeout(()=>{uni.navigateBack()},1000)}})}).catch(err=>{console.log(err);})} else {wx.openCustomerServiceChat({extInfo: {url: _this.$Route.query.extInfoUrl},corpId: _this.$Route.query.corpId||_this.qywx_company_id,success(res) {console.log(res, 'success');},fail(err) {console.log(err, 'err');},complete(res) {setTimeout(()=>{uni.navigateBack()},1000)}})}} else {uni.navigateBack()}}})},
