/**
     * Step 1: 重定向到sina微博登錄,請求授權碼CODE
     * 
 
https://api.weibo.com/oauth2/authorize?client_id=123050457758183&redirect_uri=http://www.example.com/response&response_type=code
     *
     * @param resp
     * @throws Exception
     */
    @RequestMapping("/weibo/login")
    public void weiboLogin(HttpServletResponse resp) throws Exception {
        String authorizeUrl 
 
= baseAuthorizeUrl + "?client_id=" + appKey + "&redirect_uri=" + redirectUri + "&response_type=code";
        resp.sendRedirect(authorizeUrl);
    }

/**
 * Step 2: 登錄回調，獲取Code
 *
 * @param req
 * 
 
@throws Exception
 */
@RequestMapping("/weibo/callback")
public String qqCallback(HttpServletRequest req) throws Exception {
    String code = req.getParameter("code");
    //獲取Access Token,並返回給頁面
    return getAccessToken(code);
}

3.通過 授權code獲取access_token

/**
 * Step 3: 通過code獲取access_token
 *
 * @param resp
 * @param code 認證碼
 * @return
 * @throws Exception
 */
private String getAccessToken(String code) throws Exception {
    //拼接請求URL
    String tokenUrl = baseTokenUrl + "?client_id=" + appKey + "&client_secret=" + appSecret + "&grant_type=authorization_code&code=" + code + "&redirect_uri=" + redirectUri;

    //發送post請求,獲取響應字符串
    String resp = RestHttpClient.sendHttpPostRequest(tokenUrl);

    return resp;
}

baseTokenUrl為 https://api.weibo.com/oauth2/access_token

4.通過token和uid調用微博api，例如查詢微博用戶信息

/**
 * Step 4: 根據Token和用戶ID獲取用戶信息
 * access_token:2.00AZrTrB5jlucE809b31fc07I9H_XC, uid:1706396054
 *
 * @param access_token
 * @param uid
 * @return
 * @throws Exception
 */
@RequestMapping("/weibo/userInfo")
public String getUserInfo(String access_token, String uid) throws Exception {
    //拼接請求URL
    String userInfoUrl = baseUserInfoUrl + "?access_token=" + access_token + "&uid=" + uid;
    System.out.println(userInfoUrl);

    //發送請求,獲取響應字符串
    String resp = RestHttpClient.sendHttpGetRequest(userInfoUrl);

    //返回響應字符串
    return resp;
}

baseUserInfoUrl為 https://api.weibo.com/2/users/show.json
