java 发送一个post请求 用form-data格式 请求头的requestType-Content设置为ModelingStand

ard

可以使用Java的HttpURLConnection类来发送POST请求，并设置请求头为ModelingStandard。以下是示例代码：

import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;

public class PostFormDataExample {
    public static void main(String[] args) throws IOException {
        // 设置请求URL
        URL url = new URL("https://example.com/api");

        // 创建连接对象
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("POST");

        // 设置请求头
        conn.setRequestProperty("requestType-Content", "ModelingStandard");
        
        // 设置请求正文
        String requestBody = "name=John&age=30";
        conn.setDoOutput(true);
        try (OutputStream os = conn.getOutputStream()) {
            byte[] input = requestBody.getBytes("utf-8");
            os.write(input, 0, input.length);
        }

        // 发送请求并获取响应
        int responseCode = conn.getResponseCode();
        System.out.println("Response Code: " + responseCode);
        try (BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(), "utf-8"))) {
            StringBuilder response = new StringBuilder();
            String responseLine = null;
            while ((responseLine = br.readLine()) != null) {
                response.append(responseLine.trim());
            }
            System.out.println("Response Body: " + response.toString());
        }
    }
}
