java代码创建钉钉工单后再获取钉钉工单改怎样实现

您可以通过DingTalk OpenAPI来实现Java代码创建钉钉工单并获取钉钉工单。首先，您需要在钉钉开发平台注册并为您的应用程序创建一个应用程序实例，然后获取该实例的相关信息，例如AppKey和AppSecret。您应该使用AppKey和AppSecret添加OAuth2.0支持，然后使用getAccess Token生成令牌。通过使用令牌，您可以调用DingTalk OpenAPI以执行创建和获取工单等操作。具体步骤可以参考DingTalk开发者文档。

java代码创建钉钉工单的实现代码

好的，您可以参考以下Java代码实现钉钉工单的创建：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.nio.charset.StandardCharsets;
import java.util.Base64;

public class CreateDingTalkTicket {

    public static void main(String[] args) {
        String accessToken = "Your_Access_Token"; // 钉钉应用的ACCESS_TOKEN
        String secret = "Your_Secret"; // 钉钉应用的SECRET
        String url = "https://oapi.dingtalk.com/topapi/v2/workrecord/add"; // 钉钉API接口URL

        try {
            // 获取当前时间戳（单位：毫秒）
            long timestamp = System.currentTimeMillis();

            // 构造请求参数
            String data = "{\"userid\":\"your_userid\",\"create_time\":\"" + timestamp + "\",\"title\":\"Your_Ticket_Title\",\"content\":\"Your_Ticket_Content\",\"url\":\"Your_Ticket_Url\"}";
            String signature = getSignature(secret, timestamp); // 获取签名
            String authHeader = "Signature " + accessToken + ":" + signature; // 构造认证头部

            // 发送POST请求
            HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Content-Type", "application/json");
            connection.setRequestProperty("Authorization", authHeader);
            connection.setDoOutput(true);
            OutputStream outputStream = connection.getOutputStream();
            byte[] dataBytes = data.getBytes(StandardCharsets.UTF_8);
            outputStream.write(dataBytes);
            outputStream.flush();
            outputStream.close();

            // 读取响应数据
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            StringBuilder response = new StringBuilder();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();
            System.out.println(response.toString()); // 打印响应数据

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    // 获取签名
    private static String getSignature(String secret, long timestamp) {
        try {
            String stringToSign = timestamp + "\n" + secret;
            byte[] hmacSHA256Bytes = hmacSha256(stringToSign.getBytes(StandardCharsets.UTF_8), secret.getBytes(StandardCharsets.UTF_8));
            return Base64.getEncoder().encodeToString(hmacSHA256Bytes); // Base64编码
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    // HMACSHA256加密
    private static byte[] hmacSha256(byte[] data, byte[] key) throws Exception {
        javax.crypto.spec.SecretKeySpec signingKey = new javax.crypto.spec.SecretKeySpec(key, "HmacSHA256");
        javax.crypto.Mac mac = javax.crypto.Mac.getInstance("HmacSHA256");
        mac.init(signingKey);
        return mac.doFinal(data);
    }
}

其中，您需要根据自己的情况修改以下几个参数：

- Your_Access_Token：钉钉应用的ACCESS_TOKEN，可以在钉钉开发者后台获取。
- Your_Secret：钉钉应用的SECRET，可以在钉钉开发者后台获取。
- your_userid：创建工单的用户ID。
- Your_Ticket_Title：工单的标题。
- Your_Ticket_Content：工单的内容。
- Your_Ticket_Url：工单关联的URL。

注意，此代码仅供参考，具体实现需要根据您的实际情况进行调整。

java代码创建钉钉工单的实现

好的，您可以参考以下Java代码实现钉钉工单的创建：

import java.util.HashMap;
import java.util.Map;

        HttpURLConnection con = (HttpURLConnection) obj.openConnection();
        con.setRequestMethod("GET");
        con.setRequestProperty("User-Agent", "Mozilla/5.0");
        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();
 
        while ((inputLine = in.readLine()) != null) {

        String postJsonData = "{\"userid\":\"" + paramMap.get("userid") + "\",\"create_time\":" + paramMap.get("create_time") + ",\"title\":\"" + paramMap.get("title") + "\",\"content\":\"" + paramMap.get("content") + "\"}";
        
        con.getOutputStream().write(postJsonData.getBytes("UTF-8"));

}

请注意，您需要替换代码中的 `appkey`、`appsecret`、`agent_id`、`userid`、`title` 和 `content` 参数为您的实际值。另外，此代码中使用的是钉钉 OA API 2.0 版本，如果您使用的是旧版本的 API，可能需要做一些修改。
