2、OAuth 2.0

是目前最流行的授权机制，用来授权第三方应用，获取用户数据。

应用场景

在APP或者网页接入一些第三方应用时，时常会需要用户登录另一个合作平台，比如QQ，微博，微信的授权登录,第三方应用通过oauth2方式获取用户信息

第三方平台QQ互联

1、根据sdk4j生成授权链接地址
2、执行回调地址
3、两种场景：
1、数据库查询不到openid，
获取accessToken
然后根据accessToken得到openid，
会跳转进入另一个登入地址，
生成token，数据库存入生成的openid
2、数据库能查询到openid，
获取accessToken
然后根据accessToken得到openid，
返回用户信息，获取token令牌
4、进入首页

平台互联调用步奏：

控制层：

 // 生成qq授权登录链接
    @RequestMapping("/locaQQLogin")
    public String locaQQLogin(HttpServletRequest reqest) throws QQConnectException {
        String authorizeURL = new Oauth().getAuthorizeURL(reqest);
        return "redirect:" + authorizeURL;

    }
    //回调地址
    @RequestMapping("/qqLoginCallback")
    public String qqLoginCallback(HttpServletRequest reqest, HttpServletResponse response,HttpSession httpSession) throws QQConnectException {

        // 1.获取授权码COde
        // 2.使用授权码Code获取accessToken
        AccessToken accessTokenOj = new Oauth().getAccessTokenByRequest(reqest);
        if (accessTokenOj == null) {
            reqest.setAttribute("error", "QQ授权失败");
            return "error";
        }
        String accessToken = accessTokenOj.getAccessToken();
        if (accessToken == null) {
            reqest.setAttribute("error", "accessToken为null");
            return "error";
        }
        // 3.使用accessToken获取openid
        OpenID openidOj = new OpenID(accessToken);
        String userOpenId = openidOj.getUserOpenID();
        // 4.调用会员服务接口 使用userOpenId 查找是否已经关联过账号
        ResponseBase openUserBase = memberService.findByOpenIdUser(userOpenId);
        if(openUserBase.getCode().equals(Constants.HTTP_RES_CODE_201)){
            // 5.如果没有关联账号，跳转到关联账号页面
            httpSession.setAttribute("qqOpenid", userOpenId);
            return QQRELATION;
        }
        //6.已经绑定账号  自动登录 将用户token信息存放在cookie中
        LinkedHashMap dataTokenMap = (LinkedHashMap) openUserBase.getData();
        String memberToken=(String) dataTokenMap.get("memberToken");
        setCookie(memberToken, response);
        return INDEX;
    }

    // 没有关联openid，进行登录请求具体提交实现
    @RequestMapping(value = "/qqRelation", method = RequestMethod.POST)
    public String qqRelation(UserEntity userEntity, HttpServletRequest request, HttpServletResponse response, HttpSession httpSession) {
        // 1.获取openid
        String qqOpenid=(String) httpSession.getAttribute("qqOpenid");
        if(StringUtils.isEmpty(qqOpenid)){
            request.setAttribute("error", "没有获取到openid");
            return "error";
        }

        // 2.调用登录接口，获取token信息
        userEntity.setOpenid(qqOpenid);
        ResponseBase loginBase = memberService.qqLogin(userEntity);
        if (!loginBase.getCode().equals(Constants.HTTP_RES_CODE_200)) {
            request.setAttribute("error", "账号或者密码错误!");
            return LOGIN;
        }

        LinkedHashMap loginData = (LinkedHashMap) loginBase.getData();
        String memberToken = (String) loginData.get("memberToken");
        if (StringUtils.isEmpty(memberToken)) {
            request.setAttribute("error", "会话已经失效!");
            return LOGIN;
        }
        // 3.将token信息存放在cookie里面
        setCookie(memberToken, response);
        return INDEX;
    }
