二、在App.vue文件中加载微信的sdk
<script>
export default {
globalData: {
weixinObj: undefined,
},
onLaunch: function() {
console.log('App Launch');
//初始化页面时加载微信js-sdk
if (uni.getSystemInfoSync().platform != 'ios') {
getApp().globalData.weixinObj = jWeixin;
} else {
getApp().globalData.weixinObj = wx;
}
},
}
</script>
将获取的的js-sdk放到全局变量中缓存
三、在要调用扫一扫的页面加载企业微信接口

export default {

onShow() {
console.log("刷新页面")
},
created() {

const _this = this;
this.$nextTick(function () {

});
