0，前端vue，后端java

1，问题截图

2，通过 npm install weixin-js-sdk 安装 jssdk，然后通过 import wx from 'weixin-js-sdk' 进行引入到页面

3，wx.config 按照官方要求，传 appId，timestamp，nonceStr，signature 四个参数，jsApiList配置如下

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',
            'openAddress',
            'sendChatMessage',
            'openUserProfile',
            'getCurExternalContact',
            'getCurExternalChat'
          ]

4，wx.ready 里面调用 wx.agentConfig 传入 corpid，agentid，timestamp，nonceStr，signature，jsApiList配置如下

jsApiList: ['openUserProfile', 'getCurExternalContact', 'getCurExternalChat', 'sendChatMessage'],

5，聊天工具栏分享消息到会话

wx.invoke('sendChatMessage', {
    msgtype:"text", //消息类型，必填
    text: {
        content:"你好", //文本内容
    },
    function(res) {
      if (res.err_msg == 'sendChatMessage:ok') {
      }
   }
})

按道理说一步步按照官方文档来做，应该是不会出错的，但是我们点击发送按钮触发 sendChatMessage接口的时候，无法成功，同时 preVerifyJSAPI:fail 这个错误只触发了一次之后就没有任何触发了。
