小程序setStorageSync()存储数据丢失问题

近期小程序出现问题，我们在 miniAction接口 获取openId，openId需要在多个页面跨页面用到，用setStorage存储起来，在需要用到openId的地方用 getStorage取，但是上线后，有部分用户反映小程序登录不上去，经查是openId在传输过程中丢失了，查资料，发现 setStorage存储 会出现有的用户丢失的问题。

通过global全局来跨页面共用数据

存储：

 获取：

js

export function login(index) {
global.globalData.ceshi = '测试'
mpvue.login({
success(res) {
wx.showLoading({
title: "疯狂加载中...",
mask: true,
});
wx.setStorageSync("code", res.code);
global.globalData.code = res.code
if (res.code) {
getOpenId(res.code);
}
},
// 处理登录失败
fail(res) {
index++;
console.log(index,'index+++++')
if (index <3) {
login(index);
} else {
wx.showModal({
title: "提示",
content: "登录失败，请检查您的当前网络。", //提示错误
confirmText: "确定",

export function setUserInfo(userInfo){
wx.setStorageSync('user_info',userInfo)
global.globalData.userInfo = userInfo

// 获取用户信息
export function getUserInfo(settings){
let userInfo = wx.getStorageSync('user_info') || global.globalData.userInfo || {}


return userInfo

console.log("fail.......");
mpvue.openSetting({
success(res) {
console.log(res.authSetting);
},
});
},
complete(res) {
console.log("complete");
},
});
},
注意：

在用global存储时，需要注意现在 main.js 定义 global,如下图

否则 直接用global.globalData.user_type 会报错 user_type is not definition
