这是我的测试地址：http://ecapex.top/wx/sample/php/sample.php

以下是我的前端代码：

      // 所有要调用的 API 都要加到这个列表中
        'updateAppMessageShareData',
        'updateTimelineShareData',
        'onMenuShareAppMessage',
        'onMenuShareTimeline'
    ]
  });

  //将分享的数组组成json数组
  window.share_config = {
      "share": {
          "imgUrl": "http://ecapex.top/upload/partertalents/min/20180629202242.jpg",//分享图，默认当相对路径处理，所以使用绝对路径的的话，“http://”协议前缀必须在。
          "desc" : "你真是太棒了",//摘要,如果分享到朋友圈的话，不显示摘要。
          "title" : '你真是非常的棒',//分享卡片标题
          "link": 'http://ecapex.top',//分享出去后的链接，这里可以将链接设置为另一个页面。
          "success":function(){//分享成功后的回调函数
          },
          'cancel': function () {
              // 用户取消分享后执行的回调函数
          }
      }
  };

  wx.ready(function () {
    // 在这里调用 API
      //判断当前客户端版本是否支持指定JS接口
      wx.checkJsApi({
          jsApiList: [

              // 如：{"checkResult":{"chooseImage":true},"errMsg":"checkJsApi:ok"}
          }
      });

  });

      wx.onMenuShareAppMessage(share_config.share);
  }

有没有大佬告诉下，到底是怎么回事啊？我的接口权限、js安全域名都是OK的，方便的话可以加我QQ指点下我825114245
