WinForm调用钉钉获取考勤结果

2022-07-13 21:28:04

关注点：

1、钉钉AccessToken的获取和防止过期

2、使用TPL并行编程调用钉钉接口

需求详解

公司前台有个大屏，领导想显示全部员工的考勤结果统计情况和车间的实时监控视频，还有车间的看板。简单说就是把大屏分割成几个区域。现在遇到的难题是钉钉获取考勤结果的api是只有明细记录，比如你公司1000人，那么可能回给你2000条考勤结果。分别是上班考勤和下班考勤的。没有整个公司的，我就需要这么一条数据就行了。但人家没有这样的接口提供。卷起袖子，干！

趟坑过程

考勤打卡数据开放

业务场景

该接口仅限企业接入使用，用于返回企业内员工的实际打卡结果。比如，企业给一个员工设定的排班是上午9点和下午6点各打一次卡，即使员工在这期间打了多次，该接口也只会返回两条记录，包括上午的打卡结果和下午的打卡结果

考勤打卡数据开放

请求说明（ISV无调用权限）
如果你是ISV（应用服务商，将开发的应用上架到钉钉应用市场，提供给钉钉其他企业用户使用），则无调用权限
如果你是企业内部开发者（将自己公司的HR、OA、客户管理、业务管理等系统接入钉钉），有权限调用
2017-10-16更新：新增用户userId列表参数(userIdList)和分页参数(offset,limit)，提升接口稳定性。

Https请求方式: POST

https://oapi.dingtalk.com/attendance/list?access_token=ACCESS_TOKEN

请求包结构体

{

    "workDateFrom": "yyyy-MM-dd hh:mm:ss",

    "workDateTo": "yyyy-MM-dd hh:mm:ss",

    "userIdList":["员工UserId列表"],    // 必填，与offset和limit配合使用，不传表示分页获取全员的数据

    "offset":0,    // 必填，第一次传0，如果还有多余数据，下次传之前的offset加上limit的值

    "limit":1,     // 必填，表示数据条数，最大不能超过50条
}

参数说明

参数	参数类型	必须	说明
access_token	String	是	调用接口凭证
workDateFrom	String	是	查询考勤打卡记录的起始工作日
workDateTo	String	是	查询考勤打卡记录的结束工作日
userIdList	List	是	员工在企业内的UserID列表，企业用来唯一标识用户的字段
offset	Long	是	表示获取考勤数据的起始点，第一次传0，如果还有多余数据，下次获取传的offset值为之前的offset+limit
limit	Long	是	表示获取考勤数据的条数，最大不能超过50条

1)获取AccessToken

钉钉的服务器很牛X可以并行访问的。但是获取回来的数据集有点乱，其中有个关于分页的参数需要顺序读取，就是“hasMore”还有没有下一页。所以最终没有使用TPL。

        /// <summary>
        /// 获取AccessToken
        /// </summary>
        /// <returns></returns>
        private AccessToken GetAccessToken()
        {
            string URL_GetToken = "https://oapi.dingtalk.com/gettoken?corpid={0}&corpsecret={1}";
            string fileName = AppDomain.CurrentDomain.BaseDirectory + "AccessToken.xml";
            if (!System.IO.File.Exists(fileName))
            {
                string respon = Program.HttpGetRequest(string.Format(URL_GetToken, Program.CorpId, Program.CorpSecret));
                DingTalkRespond obj = JsonConvert.DeserializeObject<DingTalkRespond>(respon);
                if (obj != null && obj.errcode == 0)
                {
                    var result = new AccessToken
                    {
                        access_token = obj.access_token,
                        expires_in = GetCurrentTimeStamp()
                    };
                    SerializerHelper.SerializerToXML(fileName, result);
                    return result;
                }
                else
                    return new AccessToken
                    {
                        access_token = obj.access_token,
                        expires_in = GetCurrentTimeStamp()
                    };
            }
            else
            {
                var fileResult = SerializerHelper.LoadFromXML<AccessToken>(fileName);
                long ts = (GetCurrentTimeStamp() - fileResult.expires_in) / 1000;
                if (ts >= 7200)
                {
                    string respon = Program.HttpGetRequest(string.Format(URL_GetToken, Program.CorpId, Program.CorpSecret));
                    DingTalkRespond obj = JsonConvert.DeserializeObject<DingTalkRespond>(respon);
                    if (obj != null && obj.errcode == 0)
                    {
                        fileResult.access_token = obj.access_token;
                        fileResult.expires_in = GetCurrentTimeStamp();
                        SerializerHelper.SerializerToXML(fileName, fileResult);
                    }
                }
                return fileResult;
            }
        }

2)获取企业总人数

/// <summary>
        /// 获取公司总人数
        /// </summary>
        /// <returns></returns>
        private int GetFactoryEmployeeCount(AccessToken token)
        {
            int result = 0;
            string url = string.Format("https://oapi.dingtalk.com/user/get_org_user_count?access_token={0}&onlyActive=0", token.access_token);
            string jsonObj = Program.HttpGetRequest(url);
            var objResult = JsonConvert.DeserializeObject<DingTalkRespond>(jsonObj);
            if (objResult != null && objResult.errcode == 0)
                result = objResult.count;
            return result;
        }

3)获取全体员工的考勤结果

  /// <summary>
        /// 获取指定页的考勤结果
        /// </summary>
        /// <param name="offset"></param>
        /// <returns></returns>
        private void GetAttendance(AccessToken token)
        {
            EmployeeAttendanceList.Clear();
            string url = string.Format("https://oapi.dingtalk.com/attendance/list?access_token={0}", token.access_token);
            int offset = 0;
            bool bHasMore = true;
            while (bHasMore)
            {
                var request = new AttendanceRequest
                {
                    workDateFrom = DateTime.Now.ToString("yyyy-MM-dd") + " 00:00:00",
                    workDateTo = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"),
                    limit = 50,
                    userIdList = null,
                    offset = offset * 50
                };
                string jsonRequest = JsonConvert.SerializeObject(request).Replace("null", "[]");
                string jsonResult = Program.PostJsonData(url, jsonRequest);
                var objResult = JsonConvert.DeserializeObject<DingTalkRespond>(jsonResult);
                if (objResult != null && objResult.errcode == 0)
                {
                    foreach (var item in objResult.recordresult)
                    {
