授权流程讲解
我们在使用微信中的小程序时，都会要我们进行授权，例如下面这样
那么这样的用户授权时怎么实现的呢，这一篇主要就是讲解用户授权登录的流程！！！
图片说明：
1.客户端调用 wx.login() 获取临时登录凭证code，通过 wx.request() 发起网络请求，将 code 传给服务端
2、服务端使用 code + appid + appsecret 向微信换取 （调用 auth.code2Session 接口）用户唯一标识openid 和 会话密钥session_key
3、服务端自定义 登录状态token（与openid、session_key关联）返回客户端
4、客户端将 登录状态token 存入 缓存storage（推荐使用 wx.setStorageSync(‘key’, ‘value’) 同步存储）
5、客户端wx.request() 发起请求时，携带登录状态token （推荐使用 wx.getStorageSync(‘key’) 同步获取）
6、服务端通过 登录状态token 查询到对应 openid 和 session_key
7、验证成功后，返回业务数据给客户端
一.用户信息授权登录
其中有两种方法，第一种方法是点击登录之后便直接获取了用户的个人信息，而第二种会询问用户是否同意授权，这样的话，会更具安全性
1.wx.login
这个方法主要用于获取用户的登录凭证（code）。在用户进入小程序时，前端会调用wx.login来获取这个code，然后将这个code发送给后台服务器。后台服务器再向微信发送请求，通过这个code来获取用户的唯一标识（openid）以及本次登录的会话密钥（session_key）。之后，后台服务器将这两个信息传回前台，用于自定义登录状态和用户唯一标识
2.wx.getUserProfile
这个方法主要用于获取用户的更多详细信息，如昵称、头像等。在使用这个方法之前，需要先调用wx.authorize接口来发起授权请求，请求用户授权提供这些信息。如果用户同意授权，就可以通过调用wx.getUserProfile方法来获取这些详细信息
3.代码
WXML
<!--pages/index/index.wxml--> <view> <button wx:if="{{canIUseGetUserProfile}}" type="primary" class="wx-login-btn" bindtap="getUserProfile">微信直接登录1</button> <button wx:else open-type="getUserInfo" type="primary" class="wx-login-btn" bindgetuserinfo="wxLogin">微信直接登录2</button> <image mode="scaleToFill" src="{{userInfo.avatarUrl}}" /> <text>昵称:{{userInfo.nickName}}</text> </view>JS
// 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; } }, /** * 生命周期函数--监听页面初次渲染完成 */ onReady() { }, /** * 生命周期函数--监听页面显示 */ onShow() { }, /** * 生命周期函数--监听页面隐藏 */ onHide() { }, /** * 生命周期函数--监听页面卸载 */ onUnload() { }, /** * 页面相关事件处理函数--监听用户下拉动作 */ onPullDownRefresh() { }, /** * 页面上拉触底事件的处理函数 */ onReachBottom() { }, /** * 用户点击右上角分享 */ onShareAppMessage() { } })用户授权登录后，后台便会保存用户的信息
二.用户信息授权登录之后台交互
前期准备
①准备数据接口
②密钥以及appid
后端代码

三.手机号授权登录之后台交互
手机号授权登录的流程与用户信息授权登录流程是一样的，只不过向微信调用的接口有所不同
后端代码
