网站接入QQ登录最新2020 java版本

1.首先先注册账号,然后填资料审核,等个三四天吧大概

https://connect.qq.com/

2.审核通过后点击创建应用,把备案号什么的都填(这个审核两天之内一般)

!!! 这里有个重点,网站地址只能填一下,回调地址随便填一个,通过后可以随便改的

3. 整理java代码
我的是springBoot项目 先导入依赖,官网好像没有java版本的jar包了,我是找个网上坐标

     <!--QQ登录的包sdk-->
        <dependency>
            <groupId>net.gplatform</groupId>
            <artifactId>Sdk4J</artifactId>
            <version>2.0</version>
        </dependency>

然后编写创建一个配置文件 qqconnectconfig.properties 名字建议一致,改完了以后复制粘贴即可

app_ID = 填成自己的ID 
app_KEY = 填成自己的KEY
redirect_URI = 填成自己的回调地址
grant_type=authorization_code
scope = get_user_info,add_topic,add_one_blog,add_album,upload_pic,list_album,add_share,check_page_fans,add_t,add_pic_t,del_t,get_repost_list,get_info,get_other_info,get_fanslist,get_idollist,add_idol,del_ido,get_tenpay_addr
baseURL = https://graph.qq.com/
getUserInfoURL = https://graph.qq.com/user/get_user_info
accessTokenURL = https://graph.qq.com/oauth2.0/token
authorizeURL = https://graph.qq.com/oauth2.0/authorize
getOpenIDURL = https://graph.qq.com/oauth2.0/me
addTopicURL = https://graph.qq.com/shuoshuo/add_topic
addBlogURL = https://graph.qq.com/blog/add_one_blog
addAlbumURL = https://graph.qq.com/photo/add_album
uploadPicURL = https://graph.qq.com/photo/upload_pic
listAlbumURL = https://graph.qq.com/photo/list_album
addShareURL = https://graph.qq.com/share/add_share
checkPageFansURL = https://graph.qq.com/user/check_page_fans
addTURL = https://graph.qq.com/t/add_t
addPicTURL = https://graph.qq.com/t/add_pic_t
delTURL = https://graph.qq.com/t/del_t
getWeiboUserInfoURL = https://graph.qq.com/user/get_info
getWeiboOtherUserInfoURL = https://graph.qq.com/user/get_other_info
getFansListURL = https://graph.qq.com/relation/get_fanslist
getIdolsListURL = https://graph.qq.com/relation/get_idollist
addIdolURL = https://graph.qq.com/relation/add_idol
delIdolURL = https://graph.qq.com/relation/del_idol
getTenpayAddrURL = https://graph.qq.com/cft_info/get_tenpay_addr
getRepostListURL = https://graph.qq.com/t/get_repost_list
version = 2.0.0.0

前端代码 这里的话 根据自己的实际情况

  <a href="/qqLogin" onclick="layer.msg('正在通过QQ登入', {icon:16, shade: 0.1, time:0})" >
     <img class="avatar size-S" src="img/qq.jpg" title="登陆">登陆
 </a>

后端java 跳转代码 这个直接复制粘贴记性

    //QQ登录的跳转
    @GetMapping("/qqLogin")
    public String qqLogin(HttpServletRequest request, HttpServletResponse response) throws Exception {
        response.setContentType("text/html;charset=utf-8");
        try {
            String authorizeURL = new Oauth().getAuthorizeURL(request);
            return "redirect:" + authorizeURL;
        } catch (Exception e) {
            return null;
        
    }

这个时候网页是可以用的

然后编写java的回调代码
Crotroller类

    //QQ登录的回调
    @GetMapping("/qqLoginBack")
    public String  qqLoginBack(HttpServletRequest request, HttpServletResponse response,HttpSession session) throws Exception {
            String code = request.getParameter("code");
            //获取到了用户信息
            Member member = QqService.LoginBack(code);
        return "redirect:/";
    }

services类,可能是jar版本太老了,jar的方法都不生效了,我就自己看着官方api文档发请求写了一个

@PropertySource("classpath:qqconnectconfig.properties")
@Service
public class QQServiceImpl {
    @Value("${app_ID}")
    private String appID;
    @Value("${app_KEY}")
    private String appKEY;
    @Value("${redirect_URI}")
    private String redirectURI;
    @Value("${grant_type}")
    private String grantType;
    @Resource
    private MemeberMapper memeber;

    //根据code查询
    public Member LoginBack(String code)  {
        Member member = new Member();
        //获取accessToken
        String  urlAccessToken = HttpUtil.get("https://graph.qq.com/oauth2.0/token?grant_type=" + grantType + "&client_id=" + appID + "&client_secret=" + appKEY + "&code=" + code + "&redirect_uri=" + redirectURI);
        //截取accessToken
        String accessToken = StrUtil.subBetween(urlAccessToken, "access_token=", "&expires_in");
       if(!StrUtil.isBlank(accessToken)){
           //获取openId
           String  urlOpenId = HttpUtil.get("https://graph.qq.com/oauth2.0/me?access_token="+accessToken);
           //截取openId
           String openId = StrUtil.subBetween(urlOpenId, "openid\":\"", "\"}");
           if(!StrUtil.isBlank(openId)){
               try {
                   //访问用户资料
                   String userMessage = HttpUtil.get("https://graph.qq.com/user/get_user_info?access_token=" + accessToken + "&oauth_consumer_key="+appID+"&openid=" + openId);
                   JSONObject jsonObject = JSONUtil.parseObj(userMessage);
                   //获取用户姓名
                   String nickname = (String)jsonObject.get("nickname");
                   //获取QQ头像
                   String nickImg = (String)jsonObject.get("figureurl_qq_1");
                    //获取QQ性别
                   String gender= (String)jsonObject.get("gender");
                 	//这里的随便怎么写
               }catch (Exception e){
                   System.out.println(e);
               }
           }
       }
        return  member;
    }


}

说一下QQ的执行流程吧

https://wiki.connect.qq.com/%E4%BD%BF%E7%94%A8authorization_code%E8%8E%B7%E5%8F%96access_token

主要的执行流程:
QQ页面登录后 ===> 会往回调函数里面穿一个code值, => 根据code值获取accessToken值 =>再根据accessToken值>获取openId值
再拿openId值去访问接口获取基本信息,这个我得注释写的很清楚了哈,具体的流程就是这样

问题一:,填了回调接口以下,只能回调到服务器上,回调不到本地?
答案:使用 第三方的映射工具,把本地的服务映射成域名.就可以.我在这里用的是小米球映射工具

问题二:QQ登录界面出现回调地址校验通知错误?
答案:在本地电脑上host目录里面配置一下
