通过钉钉考勤接口获取员工考勤信息

第一步.获取接口token

import org.json.JSONObject;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
import java.util.List;
import java.util.Map;

public class 获取钉钉token {
    public static void main(String[] args) throws IOException {
        String result = "";
        BufferedReader in = null;
        try {
            String urlNameString = "https://oapi.dingtalk.com/gettoken?appkey="+
"+&appsecret=";
            URL realUrl = new URL(urlNameString);
            // 打开和URL之间的连接
            URLConnection connection = realUrl.openConnection();
            // 建立实际的连接
            connection.connect();
            // 获取所有响应头字段
            Map> map = connection.getHeaderFields();
            // 定义 BufferedReader输入流来读取URL的响应
            in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            while ((line = in.readLine()) != null) {
                result += line;
            }
            JSonObject a = new JSonObject(result);
            result=a.getString("access_token");
            System.out.println(result);
        } catch (Exception e) {
            System.out.println("发送GET请求出现异常！" + e);
            e.printStackTrace();
        }
        // 使用finally块来关闭输入流
        finally {
            try {
                if (in != null) {
                    in.close();
                }
            } catch (Exception e2) {
                e2.printStackTrace();
            }
        }

    }
}

第二步.获取数据(先要通过另一个接口获取列id   假期没有列id需要调另外的接口)

import org.json.JSONObject;

import java.io.*;
import java.net.*;
import java.text.SimpleDateFormat;
import java.util.Calendar;


public class 获取考勤信息 {
    public static void main(String[] args) throws IOException {
        String token = "356fd847296a3d21a48e303b29e80d2a";
        JSonObject data = new JSonObject();
        String userData = "45074443952701";//设置用户名


        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");//新建日期
        //获取前月的第一天
        Calendar cal_1 = Calendar.getInstance();//获取当前日期
        cal_1.add(Calendar.MONTH, -1);
        cal_1.set(Calendar.DAY_OF_MONTH, 1);//设置为1号,当前日期既为本月第一天
        String firstDay = (String) format.format(cal_1.getTime());
        //获取前月的最后一天
        Calendar cale = Calendar.getInstance();
        cale.set(Calendar.DAY_OF_MONTH, 0);//设置为0号,则为当前月份的前一天
        String lastDay = (String) format.format(cale.getTime());

//        data.put("leave_names","事假,婚假,产假,病假");
        data.put("from_date", firstDay);
        data.put("to_date", lastDay);
        data.put("userid",userData);
       data.put("column_id_list", "17509665,17509663,157862036,17509674,17509677");//需要的列的id

        URL onePersonURL = new URL("https://oapi.dingtalk.com/topapi/attendance/getupdatedata?access_token=" + token);
        URL getattcolumnsURL = new URL("https://oapi.dingtalk.com/topapi/attendance/getattcolumns?access_token=" + token);
        URL getcolumnval = new URL("https://oapi.dingtalk.com/topapi/attendance/getcolumnval?access_token=" + token);
        URL getjiaqi= new URL("https://oapi.dingtalk.com/topapi/attendance/getleavetimebynames?access_token=" + token);
        HttpURLConnection conn = (HttpURLConnection) getcolumnval.openConnection();
        conn.setRequestMethod("POST");
        conn.setDoInput(true); // 设置该连接可输入
        conn.setDoOutput(true); // 设置该连接可输出
        conn.setUseCaches(false);//不可使用缓存
        conn.setConnectTimeout(10000);//最长响应时间
        conn.setReadTimeout(10000);//最长读取时间
        conn.setRequestProperty("Content-type", "text/plain");//设定传送的内容类型是可序列化的java对象
        conn.setRequestProperty("accept", "text/plain");//设置接收类型

        DataOutputStream dos = new DataOutputStream(conn.getOutputStream());//输出参数
        dos.writeBytes(data.toString());
        dos.flush();
        dos.close();


        BufferedReader Reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));//默认调用connect
        String line, resultStr = "";//接收结果
        while (null != (line = Reader.readLine())) {
            resultStr += line;
        }
        Reader.close();


        System.out.println(resultStr);

    }
}
