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

<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) {debuggerconsole.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

①准备数据接口

②密钥以及appid

const api = require('../config/api.js');/*** Promise封装wx.checkSession*/
function checkSession() {return new Promise(function(resolve, reject) {wx.checkSession({success: function() {resolve(true);},fail: function() {reject(false);}})});

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
