本文實例為大家分享了Java模擬實現QQ三方登錄的具體代碼，供大家參考，具體內容如下

本次例子模擬這樣的情況：

一共有2個spring boot應用：

一個是某公司的web，第二個是QQ服務端。

某公司的應用為127.0.0.1:8082

QQ服務端為127.0.0.1:8081

演示如下：

點擊使用QQ登錄：

在彈出的界面輸入數據點擊登錄后：

關鍵代碼如下：

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標準化 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服務端：

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); } }
