数据流形式参数 访问counter

下面是代码

package dfsdfsdf;

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

public class shujuliu {

	public static void main(String[] args) {
		String requestString = "需要传递的数据";
		HttpURLConnection httpURLConnection;
		try {
			// 建立链接
			URL gatewayUrl = new URL("请求url");
			httpURLConnection = (HttpURLConnection) gatewayUrl.openConnection();

			// 设置连接属性
			httpURLConnection.setDoOutput(true);
			httpURLConnection.setDoInput(true);
			httpURLConnection.setUseCaches(false);

			// 获得数据字节数据，请求数据流的编码，必须和下面服务器端处理请求流的编码一致
			byte[] requestStringBytes = requestString.getBytes();

			// 设置请求属性
			httpURLConnection.setRequestProperty("Content-length", ""
					+ requestStringBytes.length);
			httpURLConnection.setRequestProperty("Content-Type",
					"application/octet-stream");

			// 建立输出流，并写入数据
			OutputStream outputStream = httpURLConnection.getOutputStream();
			outputStream.write(requestStringBytes);
			outputStream.close();

			// 获得响应状态
			int responseCode = httpURLConnection.getResponseCode();

			if (HttpURLConnection.HTTP_OK == responseCode) {
				// 当正确响应时处理数据

				System.out.println("");
				System.out.println("Http Response OK...");
				System.out.println("");

				StringBuffer responseBuffer = new StringBuffer();

				String readLine;
				BufferedReader responseReader;
				// 处理响应流，必须与服务器响应流输出的编码一致
				responseReader = new BufferedReader(new InputStreamReader(
						httpURLConnection.getInputStream()));
				while ((readLine = responseReader.readLine()) != null) {
					responseBuffer.append(readLine).append("\n");
				}
				responseReader.close();

				System.out.println("Http Response:" + responseBuffer);
			}

		} catch (IOException e) {
			e.fillInStackTrace();
		}
