Java模拟实现QQ三方登录(单点登录2.0)
本文实例为大家分享了Java模拟实现QQ三方登录的具体代码,供大家参考,具体内容如下
本次例子模拟这样的情况:
一共有2个spring boot应用:
一个是某公司的web,第二个是QQ服务端。
某公司的应用为127.0.0.1:8082
QQ服务端为127.0.0.1:8081
演示如下:
点击使用QQ登录:
在弹出的界面输入数据点击登录后:
关键代码如下:
某公司web端:
MyController.java
package cn.it1995.login.controller; import cn.it1995.login.util.CookieUtil;import cn.it1995.login.util.Result;import com.alibaba.fastjson.JSON;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.http.ResponseEntity;import org.springframework.util.LinkedMultiValueMap;import org.springframework.util.MultiValueMap;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.client.RestTemplate; import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.util.Map;import java.util.concurrent.ConcurrentHashMap;import java.util.concurrent.ConcurrentMap; @RestControllerpublic class MyController { @Autowired private RestTemplate restTemplate; private static final String USER_KEY='user_key'; private ConcurrentMap<String, Object> user = new ConcurrentHashMap<>(); @GetMapping('/getUser') public Object getUser(HttpServletRequest request, HttpServletResponse response){ String loginCookie = CookieUtil.getLoginCookie(request, response); Object o = user.get(loginCookie); return Result.success(o); } @PostMapping('/loginByQQ') public Object loginByQQ(String token, HttpServletResponse response, HttpServletRequest request){ MultiValueMap<String, Object> paramMap = new LinkedMultiValueMap(); paramMap.add('token', token); ResponseEntity<Object> objectResponseEntity = restTemplate.postForEntity('http://127.0.0.7:8081/getLoginInfo', paramMap, Object.class); Object body = objectResponseEntity.getBody(); String uuid = CookieUtil.setLoginCookie(request, response); //json标准化 String newJson = body.toString().replace('=', ':'); System.out.println(newJson); Map map = JSON.parseObject(newJson, Map.class); Map data = JSON.parseObject(map.get('data').toString(), Map.class); user.put(uuid, data); return Result.success(); }}
QQ服务端:
UserController.java
package cn.it1995.qqServer.controller; import cn.it1995.qqServer.util.JwtUtil;import cn.it1995.qqServer.util.Result;import com.alibaba.fastjson.JSON;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.*; import java.util.HashMap;import java.util.Map;import java.util.UUID; @Controllerpublic class UserController { @ResponseBody @RequestMapping('/login') public Object login(@RequestParam('username') String username, @RequestParam('password') String password){ Map<String, Object> map = new HashMap<>(); map.put('username', username); map.put('password', password); String jwt = JwtUtil.createJWT(UUID.randomUUID().toString(), JSON.toJSONString(map), 3600 * 24); return jwt; } @ResponseBody @RequestMapping('/getLoginInfo') public Object getLoginInfo(String token){ String subject = JwtUtil.parseJWT(token).getSubject(); return Result.success().data(subject); } }
