API和组件 小程序 Bug onShareAppMessage(Object) 客户端 6.6.7 2.0.4

分享时,使用onShareAppMessage,var that=this时console.log(this)    中可以打印出来已经获取到的详情页数据,但是分享出去却是空的,空白页显示未获取到数据

代码如下:

var server = require('../../../utils/server');

var WxParse = require('../../../wxParse/wxParse.js');


Page({

data: {

goods: {},

sc: [],

status: 0,

current: 0,

tabStates: [true, false, false],

tabClasss: ["text-select", "text-normal", "text-normal"],

galleryHeight: getApp().screenWidth,

tab: 0,

goods_num: 1,

textStates: ["view-btns-text-normal", "view-btns-text-select"],

article: '<div>我是HTML代码</div>',


},


onLoad: function (options) {


var goodsId = options.objectId;


var user_id = getApp().globalData.userInfo.user_id




var that = this


server.getJSON('/Goods/goodsInfo/id/' + goodsId + '/user_id/' + user_id, function (res) {


var goodsInfo = res.data.result;


var sc = res.data.result.sc;


that.setData({

goods: goodsInfo,

sc: sc,

name: res.data.result.goods.goods_name,

objectId: res.data.result.goods.goods_id,//增加分享添加

});

console.log(res.data.result.goods.goods_id)

that.checkPrice();

WxParse.wxParse('article', 'html', that.data.goods.goods.goods_content, that, 5);

});

console.log('onLoad-options.objectId:' + options.objectId);
