• Objective
  Due to the separation of the company back and forth, here is mainly about the background of the implementation of logic and process, the front-end related to a bit. Front-end we are using the QR code embedded in our web page.

The process is as follows:

1. Login nail Backstage Create an enterprise app

2. Obtain Access_token according to AppID and App_secret

• The Access_token is valid for 2 hours and can be cached on its own.

    /**     * 获取access token 有效期2 个小时，有效期获取，值不变，时间延长     * @return     */    public static DdResult getAccessToken(String appid, String secret){        String requestUrl = "https://oapi.dingtalk.com/sns/gettoken?appid=APPID&appsecret=APPSECRET";        requestUrl = requestUrl.replace("APPID", appid).replace("APPSECRET", secret);        String accessTokenResult = HttpClientUtil.doGet(requestUrl);        log.info("------->> >> -------->> request ding ding access token result:{}", accessTokenResult);        if (StringUtils.isNotBlank(accessTokenResult)) {            return JSON.parseObject(accessTokenResult, new TypeReference<DdResult>(){});        }        return new DdResult();    }

3. Get Persistent Code Persistent_code

• Based on the code returned from the front end and the Access_token obtained in the previous step get Persistent_code, the persistent code has no expiration time temporarily.

    /**     * 根据code与accessToken获取用户的持久授权码     * @param code 临时码，只能使用一次     * @param accessToken 有效期，2个小时     * @return     */    public static DdResult getPersistentCode(String code, String accessToken){        String requestUrl = "https://oapi.dingtalk.com/sns/get_persistent_code?access_token=" + accessToken;        HashMap<String, String> params = Maps.newHashMap();        params.put("tmp_auth_code", code);        String accessTokenResult = HttpClientUtil.doPostJson(requestUrl, JSON.toJSONString(params));        log.info("------->> >> -------->> ding ding persistent token result: {}", accessTokenResult);        return JSON.parseObject(accessTokenResult, DdResult.class);    }

4. Get the user authorization code Sns_token

• Based on the Openid,persistent_code obtained in the previous step, get the sns_token with the Access_token obtained in 2 steps

    /**     * 获取sns token     * @param accessToken     * @param openId     * @param persistentCode     * @return     */    public static DdResult getSnsToken(String accessToken, String openId, String persistentCode) {        HashMap<String, String> params = Maps.newHashMap();        params.put("openid", openId);        params.put("persistent_code", persistentCode);        String snsTokenRequestUrl = "https://oapi.dingtalk.com/sns/get_sns_token?access_token=" + accessToken;        String result = HttpClientUtil.doPostJson(snsTokenRequestUrl, JSON.toJSONString(params));        log.info("------->> >> -------->> request ding ding sns token result:{}", result);        return JSON.parseObject(result, new TypeReference<DdResult>(){});    }

5. Get user Information

• Gets the user information based on the Sns_token obtained in the previous step.

    public static DdResult getUserInfo(String snsToken) {        String userInfoRequestUrl = "https://oapi.dingtalk.com/sns/getuserinfo?sns_token=" + snsToken;        String result = HttpClientUtil.doGet(userInfoRequestUrl);        log.info("------->> >> -------->> >> request ding ding sns token result:{}", result);        if (StringUtils.isBlank(result)) {            return null;        }        return JSON.parseObject(result, new TypeReference<DdResult>() {});    }

To get the user's information, you can do the login operation.
