如果集算器做为 http 服务时，访问集算器 url 就是普通 url，比如：http://192.168.1.107:8503/test1.dfx()，那么 java 获取这个返回内容就和普通 java 获取常规 http url 内容一致，这个可以在网上搜索下，我做了个简单例子：

import java.io.*;
import java.net.*;

public class testHttp {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		StringBuffer buffer = new StringBuffer();
		URL url;
		try {
			url = new URL("http://192.168.1.107:8503/test1.dfx()");
        // http协议传输
        HttpURLConnection httpUrlConn = (HttpURLConnection) url.openConnection();
        httpUrlConn.setDoOutput(true);
        httpUrlConn.setDoInput(true);
        httpUrlConn.setUseCaches(false);
        // 设置请求方式（GET/POST）
        httpUrlConn.setRequestMethod("GET");
        if ("GET".equalsIgnoreCase("GET"))
            httpUrlConn.connect();
        // 将返回的输入流转换成字符串
        InputStream inputStream = httpUrlConn.getInputStream();
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

        String str = null;
        while ((str = bufferedReader.readLine()) != null) {
            buffer.append(str);
        }
        System.out.println("==="+buffer);
        bufferedReader.close();
        inputStreamReader.close();
        // 释放资源
        inputStream.close();
        inputStream = null;
        httpUrlConn.disconnect();
		} catch (Exception e) {
            e.printStackTrace();
        
		}
		
	}

}
