完美解决微信js-sdk在IOS系统报 wx.config报 realAuthUrl invalid signature的问题

App.vue中增加

 mounted:function(){
            uni.setStorage({
			        key: 'WxCodeUrl',
			        data:location.href
			    });
        },

再增加一个方法

 getSignUrl:function(){
                var signLink = ''
                var ua = navigator.userAgent.toLowerCase();
                if (/iphone|ipad|ipod/.test(ua)) {
                    signLink =uni.getStorageSync('WxCodeUrl');
                    if(!signLink)signLink = location.href
                } else {
                    signLink = location.href
                }
                return signLink;
            },

然后在需要验签的时候调用传给后台处理

app.globalData.getSignUrl()
