用户登录业务
单点登录(Single Sign On),简称SSO. 用户只需要登陆一次就可以访问所有相互信任的应用系统
单点登录三种常见方式
- session广播机制实现
- 使用redis+cookie实现
- 使用token实现
session广播机制实现
其实就是session复制，从一个模块登录后，存入session复制到其他模块中，但是复制会消耗资源
适合模块数小的项目
使用redis+cookie实现
在项目中任何一个模块登录后，把数据存放到两个地方
1.redis 在key：生成唯一随机值(is,用户id等等),在value：用户数据
2.cookie：把redis里面生成key值放到cookie里面
访问项目其他模块，发送请求带着cookie进行发送，获取cookie值，拿着cookie做事，
把cookie获取值，到redis进行查询，根据key进行查询，如果查询到数据就是登陆
使用token实现
在项目某个模块进行登陆，登陆后，按照某种规则生成字符串，把登陆之后用户包含到生成字符串里面，把字符串返回
1.可以把字符串通过cookie返回
2.可以把支持通过地址栏返回
在去访问项目其他模块，每次访问在地址栏都带着生成字符串，在访问模块你获取地址栏字符串，根据字符串获取用户信息，如果获取到就是登陆

在utils下的request.js添加拦截器，用于传递token信息
前端拦截器
// http request 拦截器
service.interceptors.request.use(
config => {
//判断cookie里面是否名称有guli_token
if (cookie.get('guli_token')) {
//把获取cookie值放到header里面
config.headers['token'] = cookie.get('guli_token');
}
return config
},
err => {
return Promise.reject(err);
})注意第四步哪里老师是写的this.loginInfo = response.data.data.userInfo;但是会报json解析错误，可以加个JSON.stringify
//登录的方法
submitLogin() {
//第一步 调用接口进行登录，返回token字符串
loginApi.submitLoginUser(this.user).then((response) => {
//第二步 获取token字符串放到cookie里面
//第一个参数cookie名称，第二个参数值，第三个参数作用范围
cookie.set("guli_token", response.data.data.token, {
domain: "localhost",
});
//第四步 调用接口 根据token获取用户信息，为了首页面显示
loginApi.getLoginUserInfo().then((response) => {
//this.loginInfo = response.data.data.userInfo;
//获取返回用户信息，放到cookie里面
cookie.set(
"guli_ucenter",
JSON.stringify(response.data.data.userInfo),
{ domain: "localhost" }
);
//跳转页面
window.location.href = "/";
});
});
},修改layouts中的default.vue页面
//创建方法，从cookie获取用户信息
showInfo() {
//从cookie获取用户信息
var userStr = cookie.get("guli_ucenter");
// 把字符串转换json对象(js对象)
if (userStr) {
this.loginInfo = JSON.parse(userStr);
}
},default.vue页面显示登录之后的用户信息

},OAuth2
令牌机制，按照一定规则生成字符串，字符串包含用户信息
OAuth2主要解决两个问题
- 开放系统间授权
- 分布式访问问题
开放系统间授权的三种方式
方式一：用户名密码复制
适用于同一公司内部的多个系统，不适用于不受信的第三方应用
方式二：通用开发者key
适用于合作商或者授信的不同业务部门之间
方式三：办法令牌
接近OAuth2方式，需要考虑如何管理令牌、颁发令牌、吊销令牌，需要统一的协议，因此就有了OAuth2协议
微信登录
准备工作
1、注册
2、邮箱激活
3、完善开发者资料
4、开发者资质认证
准备营业执照，1-2个工作日审批、300元
5、创建网站应用
提交审核，7个工作日审批
6、熟悉微信登录流程
参考文档：https://open.weixin.qq.com/cgi-bin/showdocument?action=dir_list&t=resource/res_list&verify=1&id=open1419316505&token=e547653f995d8f402704d5cb2945177dc8aa4e7e&lang=zh_CN
后端
配置
P201 微信扫码 redirect_url报错的解决方案如下（解决方法引自尚硅谷公众号）
★ 第一 修改项目启动端口号为 8160
★ 第二步 把回调地址改为 wx.open.redirect_url=http://localhost:8160/api/ucenter/wx/callback
★★ 说明：目前微信登录回调可以直接请求localhost地址了，所以修改了回调配置就是http://localhost:8160

# 微信开放平台 重定向url
wx.open.redirect_url=http://localhost:8160/api/ucenter/wx/callback创建util包，创建ConstantWxUtils工具类
package com.atguigu.educenter.utils;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component
public class ConstantWxUtils implements InitializingBean {
@Value("${wx.open.app_id}")
private String appId;
@Value("${wx.open.app_secret}")
private String appSecret;
@Value("${wx.open.redirect_url}")
private String redirectUrl;
public static String WX_OPEN_APP_ID;
public static String WX_OPEN_APP_SECRET;
public static String WX_OPEN_REDIRECT_URL;
@Override
public void afterPropertiesSet() throws Exception {
WX_OPEN_APP_ID = appId;
WX_OPEN_APP_SECRET = appSecret;
WX_OPEN_REDIRECT_URL = redirectUrl;
}
}创建controller生成登录二维码
注意这个controller要使用@Controller，因为不是要返回json字符串，还是要返回二维码
也要注意nginx的配置文件
要对redirect_url进行url编码
//生成微信扫描二维码
@GetMapping("login")
public String getWxCode(){
//固定地址，后面拼接参数
String url = "https://open.weixin.qq.com/connect/qrconnect" +
"?appid=%s" +
"&redirect_uri=%s" +
"&response_type=code" +
"&scope=snsapi_login" +
"&state=%s" +
"#wechat_redirect";
//对redirect_url进行编码
String redirectUrl=ConstantWxUtils.WX_OPEN_REDIRECT_URL;
try {
redirectUrl= URLEncoder.encode(redirectUrl, "utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
String finalurl = String.format(url, ConstantWxUtils.WX_OPEN_APP_ID, redirectUrl, "atguigu");
//重定向到请求微信地址里面
return "redirect:"+finalurl;
