Front-end page

 

<script type=text/javascript>       wx.config({           debug: false,           appId: 'wx9a46bbc1613c1b6b',           timestamp: '<%= timestamp %>',           nonceStr: '<%= nonceStr %>',           signature: '<%=signature %>',           jsApiList: [        'checkJsApi',        'onMenuShareTimeline',        'onMenuShareAppMessage',        'onMenuShareQQ',        'onMenuShareWeibo',        'hideMenuItems',        'showMenuItems',        'hideAllNonBaseMenuItem',        'showAllNonBaseMenuItem',        'translateVoice',        'startRecord',        'stopRecord',        'onRecordEnd',        'playVoice',        'pauseVoice',        'stopVoice',        'uploadVoice',        'downloadVoice',        'chooseImage',        'previewImage',        'uploadImage',        'downloadImage',        'getNetworkType',        'openLocation',        'getLocation',        'hideOptionMenu',        'showOptionMenu',        'closeWindow',        'scanQRCode',        'chooseWXPay',        'openProductSpecificView',        'addCard',        'chooseCard',        'openCard'      ]       });   </script>

If an error occurs, use the official signature verification tool www.bkjia.com to verify that the signature algorithm is correct. Officially, the signed url is easy to cause invalid signature. Therefore, the url is replaced by Request. Url. AbsoluteUri. ToString (), and the problem persists.

 

The above js Code was originally placed in a js file. Later, the wx. config was cut out and placed on the page, and the problem was solved.
