Discussion on technical solutions for realizing real-time location sharing by docking with DingTalk interface

With the rapid development of mobile Internet, real-time location sharing has become a common function for many applications. For companies and teams, understanding the location of members in real time can help them work better together and improve work efficiency. As a very popular enterprise-level office software, DingTalk provides a rich API interface, which can be easily integrated by developers into their own applications. This article will explore a technical solution based on DingTalk interface docking to achieve real-time location sharing function, and provide corresponding code examples.

First of all, we need to understand several key interfaces provided by DingTalk: obtain AccessToken interface, obtain user userid interface and send work message interface.

Get AccessToken interface is used to obtain the Token required when calling other DingTalk interfaces. The Token is valid for 2 hours. We can use HTTP GET request method to call this interface, and the request URL is as follows:

GET https://oapi.dingtalk.com/gettoken?appkey=APP_KEY&appsecret=APP_SECRET

Among them, APP_KEY and APP_SECRET require the developer to be on the DingTalk developer platform Get it after registering the app.

After obtaining the Token through the AccessToken interface, we can send location messages to the specified user through the Send Work Message interface. Location messages need to set latitude (latitude), longitude (longitude) and title (location name). The sample request URL is as follows:

POST https://oapi.dingtalk.com/topapi/message/corpconversation/asyncsend_v2?access_token=ACCESS_TOKEN

Before sending location messages through the send work message interface, we need to obtain the user's userid . The user userid interface allows users to scan the DingTalk QR code within the enterprise to log in and return user information. The sample request URL is as follows:

GET https://oapi.dingtalk.com/user/getuserinfo?access_token=ACCESS_TOKEN&code=CODE

where CODE is the temporary authorization code returned after the user scans the QR code to log in.

Let’s implement a Java-based sample code to show how to call the DingTalk interface to achieve real-time location sharing:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class DingTalkApiUtils {

    private static final String APP_KEY = "YOUR_APP_KEY";
    private static final String APP_SECRET = "YOUR_APP_SECRET";
    private static final String ACCESS_TOKEN_URL = "https://oapi.dingtalk.com/gettoken?appkey=" + APP_KEY + "&appsecret=" + APP_SECRET;

    public static String getAccessToken() throws IOException {
        URL url = new URL(ACCESS_TOKEN_URL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("GET");
        int responseCode = connection.getResponseCode();
        if (responseCode == 200) {
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            StringBuilder response = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();
            return parseAccessToken(response.toString());
        }
        return null;
    }

    private static String parseAccessToken(String response) {
        // 解析JSON字符串获取AccessToken
        // 返回AccessToken
    }

    public static String getUserid(String code) throws IOException {
        String accessToken = getAccessToken();
        String url = "https://oapi.dingtalk.com/user/getuserinfo?access_token=" + accessToken + "&code=" + code;
        // 发送HTTP GET请求，获取用户userid
        // 返回userid
    }

    public static void sendLocationMessage(String accessToken, String userid, double latitude, double longitude, String title) throws IOException {
        String url = "https://oapi.dingtalk.com/topapi/message/corpconversation/asyncsend_v2?access_token=" + accessToken;
        // 构造发送位置消息的请求参数
        // 发送HTTP POST请求，发送位置消息
    }

    public static void main(String[] args) {
        try {
            String accessToken = getAccessToken();
            String code = "SCANNED_CODE";
            String userid = getUserid(code);
            double latitude = 31.12345;
            double longitude = 121.12345;
            String title = "公司总部";
            sendLocationMessage(accessToken, userid, latitude, longitude, title);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

This sample code demonstrates how to use Java to call the DingTalk interface. Implement real-time location sharing functionality. In the main method, we first obtain the AccessToken, then obtain the user userid based on the temporary authorization code returned by scanning the QR code to log in, and finally send the location message to the specified user.

To sum up, through the interface provided by DingTalk, we can realize the docking with DingTalk and conveniently realize the real-time location sharing function. Developers can further improve this function based on their own needs and specific business scenarios to make it more consistent with actual usage needs. We hope that the code examples in this article can provide some reference and help for developers who are new to the DingTalk interface.
