1.小程序登录微信登录接口演示
推荐使用 wx.getUserProfile 获取用户信息，开发者每次通过该接口获取用户个人信息均需用户确认
// pages/index/index.js
Page({
data: {
userInfo: {},
canIUseGetUserProfile: false,
},
onLoad() {
// if (wx.getUserProfile) {
// this.setData({
// canIUseGetUserProfile: true
// })
// }
},
getUserProfile(e) {
console.log('getUserProfile')
// 推荐使用 wx.getUserProfile 获取用户信息，开发者每次通过该接口获取用户个人信息均需用户确认
// 开发者妥善保管用户快速填写的头像昵称，避免重复弹窗
wx.getUserProfile({
desc: '用于完善会员资料', // 声明获取用户个人信息后的用途，后续会展示在弹窗中，请谨慎填写
success: (res) => {
console.log(res);
this.setData({
userInfo: res.userInfo,
hasUserInfo: true
})
}
})
},
wxLogin: function(e) {
debugger
console.log('wxLogin')
console.log(e.detail.userInfo);
this.setData({
userInfo: e.detail.userInfo
})
if (e.detail.userInfo == undefined) {
app.globalData.hasLogin = false;
util.showErrorToast('微信登录失败');
return;
}

2.小程序授权登录理论
小程序：小程序对应的项目，自己写的前端
临时的code，是一个临时的字符串
开发者服务器;小程序后台接口，自己写的后端
appid：是指小程序相对于微信软件的唯一标识
微信接口服务：微信的接口服务器，不是我们自己写的代码（看成阿里云的短信服务）
session_key：指的是当前的登录请求，指的是一次会话
openid：登录的用户（javaxl），相当于微信小程序这款软件的唯一标识
storage：看成vue中vuex

}4.微信表情包存储问题
工具->多账号调试->测试号（熊猫）->个人中心->点击登录->微信直接登录->允许(直接这样会报错，需要将MySQL安装的地方，将里面my.ini的utf8修改为utf8mb4,并且重启服务里的mysql)->重新尝试登录
