CCproxy 实现http服务器代理

大家好，欢迎来到IT知识分享网。

     有的时候需要在电脑上搭建Http代理服务器。本篇文章是在 Windows + CCProxy搭建的网络代理。

只需要勾选http选项，如下图所示。第一步

第二步

Java端http代理设定.需要引用的jar包：httpclient-4.3.1.jar、httpcore-4.3.2.jar：代理服务器地址：127.0.0.1:9988

实际请求地址为：127.0.0.1:7001地址

import java.util.List;

public class CopyOfRstHttpClientProxy {

	public static final CopyOfRstHttpClientProxy Me = new CopyOfRstHttpClientProxy();
	private static final String PLAT_STREAM_ENCODE = "UTF8";
	public static PoolingHttpClientConnectionManager cm = null;
	static {
		cm = new PoolingHttpClientConnectionManager();
		cm.setMaxTotal(200);
		cm.setDefaultMaxPerRoute(20);
		cm.setDefaultMaxPerRoute(50);
	}

	/**

	public String submit(String request) {
		// HttpClient
		CloseableHttpClient closeableHttpClient = HttpClients.custom().setConnectionManager(cm).build();
		// 依次是目标请求地址，端口号,协议类型
		HttpHost target = new HttpHost("127.0.0.1", 7001, "http");

		// 依次是代理地址，代理端口号，协议类型
		HttpHost proxy = new HttpHost("127.0.0.1", 9988, "http");
		RequestConfig config = RequestConfig.custom().setProxy(proxy).build();

		// 请求地址
		HttpPost httpPost = new HttpPost("http://127.0.0.1:7001/Demo/servlet");
		httpPost.setConfig(config);

		// 创建参数队列-Form表单格式
		List<NameValuePair> formparams = new ArrayList<NameValuePair>();
		formparams.add(new BasicNameValuePair("Xml", request));// Xml：加密后的XML交易报文
		formparams.add(new BasicNameValuePair("Sid", "01"));// Sid：请求服务ID（原文）
		UrlEncodedFormEntity entity = null;
		String result = "";
		try {
			// StringEntity形式
			// StringEntity entity = new
			// StringEntity(request,PLAT_STREAM_ENCODE);
			entity = new UrlEncodedFormEntity(formparams, PLAT_STREAM_ENCODE);
			httpPost.setEntity(entity);
			CloseableHttpResponse response = closeableHttpClient.execute(target, httpPost);
			HttpEntity httpEntity = response.getEntity();
			if (httpEntity != null) {
		           result =EntityUtils.toString(httpEntity, PLAT_STREAM_ENCODE);
			}
			// 释放资源
			closeableHttpClient.close();
		} catch (Exception e) {
			e.printStackTrace();
		}
		return result;
	}
