为什么我用了wx.getShareInfo返回解密后没有openGId

为什么我用了wx.getShareInfo返回解密后没有openGId,只有如下json

{"openId":null,"nickName":null,"gender":null,"city":null,"province":null,"country":null,"avatarUrl":null,"unionId":null,"watermark":{"appid":"XXX","timestamp":"1534411759"}}


app.js代码如下

App({

onLaunch: function (options) {

//this.checkLogin(options.shareTicket);  

this.globalData.shareInfo = null;

if (options.scene == 1044) {

that.getShareInfo(options.shareTicket);

}

},

onShow: function (options) {

this.checkLogin(options.shareTicket);

},

checkLogin: function (shareTicket) {

var that = this;

wx.checkSession({

success: function () {

if (!that.globalData.session) {

that.login(shareTicket);

}

else

{

if (shareTicket) {

that.getShareInfo(shareTicket);

}

};

},

fail: function () {

that.login(shareTicket);

}

})

},

//登录  

login: function (shareTicket) {

var that = this

wx.login({

success: function (r) {

if (r.code) {

that.decodeSession(r.code, shareTicket);

}

wx.getUserInfo({

success: function (res) {

that.globalData.userInfo = res.userInfo;

}

})

}

})

},

//解密session信息  

decodeSession: function (code, shareTicket) {

var that = this;

wx.request({

url: 'https://weixin.wlstock.com/Haogudao/GetOpenIdByCode',//向后端发起换取session_key请求的URL  

data: {

code: code

},

success: function (re) {

if (re.data != null && re.data.openid != null && re.data.openid != '') {

that.globalData.session = {

openid: re.data.openid,

key: re.data.session_key

};

if (shareTicket) {

that.getShareInfo(shareTicket);

}

}

else {

that.globalData.session = null;

}

},

fail: function (res) {

console.log(res);

}

})

},

//获取群信息  

getShareInfo: function (shareTicket) {

var that = this;

console.log('去获取getShareInfo');

wx.getShareInfo({

shareTicket: shareTicket,

success: function (res) {

console.log('去获取shareinfo');

wx.request({

url: that.globalData.APIUrl +'/DataHandle/Decrypt',//向后端发起解密请求的URL  

data: {

encryptStrOfBase64: res.encryptedData,

encryptSessionKey: that.globalData.session.key,

iv: res.iv

},

success: function (re) {

console.log('shareInfo');

console.log(re);

/*

           var msg = '';

           if (re.data.Status == 0) {

             that.globalData.shareInfo = JSON.parse(re.data.Data);

             

             msg = '来自群转发';

           }

           else {

             that.globalData.session = null;

             msg = re.data.Message;

           }

           wx.showToast({

             title: msg,

             duration: 5000

           })

           */

}

})

},

fail: function (res) {

console.log('fail');

console.log(res.errMsg);

wx.showToast({

title: 'fail:' + res.errMsg,

duration: 5000

})

}

});

},

globalData: {

userInfo: null,

session: null,

shareInfo: null,

APIUrl: "https://XXX"

}

})


index.js代码如下

var app = getApp()

Page({

data: {

ShIndex:"",

UpColor:"#04B235",

IconImg:"icon-down"

},

onShow: function () {

var that = this;

//wx.showToast({ title: '加载中', icon: 'loading', duration: 10000 })//设置加载模态框

that.GetShIndex(function (d) {//回调函数,根据数据设置页面data,更新到视图

//wx.hideToast();//隐藏加载框

console.log(d.data);

console.log(app.globalData.userInfo)

var upcolor = "#04B235";

var iconImg = "icon-down";

if (d.data.UpRatio>=0)

{

upcolor = "#f02f2f";

iconImg = "icon-up";

}

that.setData({ ShIndex: d.data, UpColor: upcolor, IconImg:iconImg })//更新数据,视图将同步更新

})

},

onLoad: function() {

wx.showShareMenu({

withShareTicket: true

});

},

//转发  

onShareAppMessage: function () {

return {

title: '转发小帮来猜',

path: '/pages/index/index',

success: function (res) {

// 转发成功  

var shareTickets = res.shareTickets;

var shareTicket = shareTickets;

wx.getShareInfo({

shareTicket: shareTicket,

success: function (res) {

console.log('success');

console.log(res);

//console.log(res);  

wx.showToast({

title: '转发成功',

duration: 5000

})

},

fail: function (res) {

console.log('fail');

console.log(res);

wx.showToast({

title: 'fail:' + res.errMsg,

duration: 5000

})

}

});

},

fail: function (res) {

// 转发失败  

}

}

} ,

GetShIndex: function (fn) {

wx.request({//请求服务器,类似ajax

url: app.globalData.APIUrl + '/DataHandle/GetSZIndex',

data: { roundId: 0},//和风天气提供用户key,可自行注册获得

header: { 'content-type': 'application/x-www-form-urlencoded; charset=UTF-8'  },

success: function (res) {

console.log(res.data);

console.log(app.globalData.openId);

fn(res.data);

}//成功后将数据传给回调函数执行

})

}

})
