if((!user.openid || (user.expires_in || Date.now()) < (Date.now() + 600))&&(!userInfo.nickName)){
wx.login({
success: function(res) {
if (res.code) {
//发起网络请求获取openid
// console.log(res.code)
wx.request({
url: ';+res.code+'&grant_type=authorization_code',
method: 'GET', // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT
// header: {}, // 设置请求的 header
success: function(res){
var obj={};
obj.openid=res.data.openid;
obj.expires_in=Date.now()+res.data.expires_in;
// console.log(obj);
wx.setStorageSync('openid', obj);//存储openid
