# QQ互联注册一个账号
网站地址:https://connect.qq.com/,添加一个应用,具体怎么申请以及需要填写的信息,腾讯官网有详细文档。注册并完成相应信息填写后,可以在应用管理中查到应用的APP ID和APP Key。(注,这个申请还是比较麻烦的,注意,域名必须备案,而且名称必须与备案名称相同)成功后如下图:
还需要添加一个回调地址(域名地址按照你的项目而定),如下图:
加入jar包

Controller编写
package com.gbq.boot.web.controller; import cn.hutool.core.util.StrUtil; import com.alibaba.fastjson.JSONObject; import com.gbq.boot.web.bean.User; import com.gbq.boot.web.comment.qqLoginComment.AuthComment; import com.gbq.boot.web.service.UserService; import org.springframework.web.bind.annotation.*; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.support.RedirectAttributes; import javax.annotation.Resource; import javax.servlet.http.HttpServletResponse; /** * 登录Controller * @author 阿前 * 2019年1月4日09:48:21 */ @RestController @RequestMapping("/login") public class LoginController { @Resource private UserService userService; @Resource private AuthComment authComment; @RequestMapping("/index") public ModelAndView index(@ModelAttribute("user") User user) { return new ModelAndView("/shop/index","user",user); } @RequestMapping("/login.html") public ModelAndView toLogin() { return new ModelAndView("login"); } @RequestMapping("/qqLogin") public void qqLogin(HttpServletResponse response)throws Exception{ //随机产生字符串 String state = StrUtil.uuid(); String url = authComment.getAuthUrl(state); System.out.println(url); //重定向 response.sendRedirect(url); } @GetMapping("/redirect") public ModelAndView getData(@RequestParam(value = "code") String code, RedirectAttributes model){ //获取token String accessToken = authComment.getAccessToken(code); System.out.println("accessToken"+accessToken); //获取openId String openId = authComment.getOpenId(accessToken); System.out.println("openId"+openId); //获取用户信息 JSONObject userInfo = authComment.getUserInfo(accessToken, openId); String myName = userInfo.getString("nickname"); User user = new User(null, "","111111",myName, System.currentTimeMillis(),"是", userInfo.getString("figureurl_2"), userInfo.getString("gender") ,1,1,"", "", openId); //通过openId查询 User usr = userService.findUsrByOpenId(openId); if (null != usr){ user.setId(usr.getId()); userService.updateById(user); }else { userService.insert(user); } model.addFlashAttribute("user", user); //重定向 return new ModelAndView("redirect:/login/index"); } }
AuthComment类编写
package com.gbq.boot.web.comment.qqLoginComment; import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONObject; import org.springframework.stereotype.Component; import java.io.IOException; import java.io.InputStream; import java.net.HttpURLConnection; import java.net.URL; import java.util.regex.Matcher; import java.util.regex.Pattern; import static org.apache.commons.io.IOUtils.toByteArray; @Component public class AuthComment { //QQ 登陆页面的URL private final static String AUTHORIZATION_URL = "https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id=%s&redirect_uri=%s&scope=%s"; //获取token的URL private final static String ACCESS_TOKEN_URL = "https://graph.qq.com/oauth2.0/token?grant_type=authorization_code&client_id=%s&client_secret=%s&code=%s&redirect_uri=%s"; // 获取用户 openid 的 URL private static final String OPEN_ID_URL = "https://graph.qq.com/oauth2.0/me?access_token=%s"; // 获取用户信息的 URL,oauth_consumer_key 为 apiKey private static final String USER_INFO_URL = "https://graph.qq.com/user/get_user_info?access_token=%s&oauth_consumer_key=%s&openid=%s"; // 下面的属性可以通过配置读取 // QQ 在登陆成功后回调的 URL,这个 URL 必须在 QQ 互联里填写过 private static final String CALLBACK_URL = "http://127.0.0.1:8080/login/redirect"; // QQ 互联应用管理中心的 APP ID private static final String APP_ID = "你的id"; // QQ 互联应用管理中心的 APP Key private static final String APP_SECRET = "你的key"; /** * QQ 登陆页面的URL * @param scope * @return */ public String getAuthUrl(String scope) { return String.format(AUTHORIZATION_URL, APP_ID, CALLBACK_URL, scope); } /** * 获取Access Token值 */ public String getAccessToken(String code){ String ur = String.format(ACCESS_TOKEN_URL, APP_ID, APP_SECRET,code, CALLBACK_URL); String compile = "access_token=(\\w*)&"; String result = this.getUrl(ur); return this.getMatcher(result,compile); } /** * 获取openId * @param accessToken * @return */ public String getOpenId(String accessToken) { String url = String.format(OPEN_ID_URL, accessToken); String compile = "openid\":\"(\\w*)\""; String result = this.getUrl(url); return this.getMatcher(result,compile); } /** * 获取qq用户信息 * @param accessToken * @param openId * @return */ public JSONObject getUserInfo(String accessToken, String openId) { String url = String.format(USER_INFO_URL, accessToken, APP_ID, openId); String result = this.getUrl(url); return JSON.parseObject(result); } private String getMatcher(String result,String compile) { //使用正则表达式解析网址 Pattern p = Pattern.compile(compile); Matcher m = p.matcher(result); m.find(); return m.group(1); } //解析url private String getUrl(String ur) { try { URL url = new URL(ur); HttpURLConnection conn = null; conn = (HttpURLConnection) url.openConnection(); conn.setConnectTimeout(5 * 1000); conn.setRequestMethod("GET"); InputStream inStream = conn.getInputStream(); byte[] data = toByteArray(inStream); String result = new String(data, "UTF-8"); System.out.println(result); return result; } catch (IOException e) { e.printStackTrace(); } return null; } }
此处不再编写userService
成功会返回json串
其中主要需要的是,nickname——qq名称,figureurl_qq_x——不同尺寸的qq头像,等等等等!

feemarker配置
注意我使用的是freemarker模板,给大家贴上freemarker配置,已经mvc配置
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-freemarker</artifactId> </dependency>freemarker: template-loader-path: classpath:/templates/ # 是否启用模板缓存。 suffix: .ftl cache: false # 模板编码。 charset: UTF-8 # 是否检查模板位置是否存在。 check-template-location: true content-type: text/html #是否启用freemarker enabled: true mvc: view: prefix: /templates/ suffix: .html static-path-pattern: /static/**
