获取企业微信userid JAVA

在企业内部使用企业微信作为通讯工具时，有时候我们需要通过编程的方式获取企业微信用户的userid，以便进行一些自动化操作，比如发送消息、获取用户信息等。本文将介绍如何通过JAVA代码来获取企业微信的userid。

前提条件

在开始之前，您需要拥有企业微信的企业账号，并且拥有相应的权限来获取用户信息。另外，您还需要在企业微信后台获取到对应的CorpID和Secret，用于进行接口调用。

代码示例

下面是一个简单的JAVA代码示例，演示了如何通过CorpID和Secret获取企业微信用户的userid。

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONException;
import com.alibaba.fastjson.JSONObject;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class GetUserId {

    public static void main(String[] args) {
        String corpId = "your_corp_id";
        String corpSecret = "your_corp_secret";
        String accessToken = getAccessToken(corpId, corpSecret);

        if(accessToken != null) {
            String userId = getUserId(accessToken, "user_name");
            System.out.println("User ID: " + userId);
        } else {
            System.out.println("Failed to get access token.");
        }
    }

    public static String getAccessToken(String corpId, String corpSecret) {
        String accessToken = null;
        try {
            String url = " + corpId + "&corpsecret=" + corpSecret;
            HttpURLConnection conn = (HttpURLConnection) new URL(url).openConnection();
            conn.setRequestMethod("GET");
            conn.setConnectTimeout(5000);
            conn.setReadTimeout(5000);

            BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            StringBuffer response = new StringBuffer();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();

            JSONObject json = JSON.parseObject(response.toString());
            accessToken = json.getString("access_token");
        } catch (Exception e) {
            e.printStackTrace();
        }

        return accessToken;
    }

    public static String getUserId(String accessToken, String userName) {
        String userId = null;
        try {
            String url = " + accessToken + "&userid=" + userName;
            HttpURLConnection conn = (HttpURLConnection) new URL(url).openConnection();
            conn.setRequestMethod("GET");
            conn.setConnectTimeout(5000);
            conn.setReadTimeout(5000);

            BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            StringBuffer response = new StringBuffer();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();

            JSONObject json = JSON.parseObject(response.toString());
            userId = json.getString("userid");
        } catch (Exception e) {
            e.printStackTrace();
        }

        return userId;
    }
}
