全网发布审核中，提交完小程序代码，体验中wx.getExtConfig为空，请问谁知道是怎么回事，开发工具都是可以的，appid=wxbb500227fb3e13a3

if (wx.getExtConfig) {

wx.getExtConfig({

success: function (res) {

console.log(res.extConfig)

console.log(res.extConfig.attr.host)

getApp().globalData.API_URL = res.extConfig.attr.host;

getApp().globalData.merchantId = res.extConfig.attr.merchantId;

getApp().globalData.appid = res.extConfig.attr.appid;

getApp().globalData.appSecret = res.extConfig.attr.appSecret;

}

})

console.log('&&&&&&'+that.globalData.API_URL)

}
