httpclient4.3 设置代理请求

     最近需要使用Httpclient做后台请求，使用的是httpclient4.3版本，apache网站上有，我这里就不提供下载链接了，搜一下就可以了，废话少说，直接上代码：

Java代码  


import java.util.ArrayList;  

import java.util.List;  

  

import org.apache.http.HttpEntity;  

import org.apache.http.HttpHost;  

import org.apache.http.NameValuePair;  

import org.apache.http.client.config.RequestConfig;  

import org.apache.http.client.entity.UrlEncodedFormEntity;  

import org.apache.http.client.methods.CloseableHttpResponse;  

import org.apache.http.client.methods.HttpPost;  

import org.apache.http.impl.client.CloseableHttpClient;  

import org.apache.http.impl.client.HttpClientBuilder;  

import org.apache.http.message.BasicNameValuePair;  

import org.apache.http.util.EntityUtils;  

  

public class HttpClientTest {  

    public static void main(String args[]) throws Exception {  

        // 创建HttpClientBuilder  

        HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();  

        // HttpClient  

        CloseableHttpClient closeableHttpClient = httpClientBuilder.build();  

        // 依次是目标请求地址，端口号,协议类型  

        HttpHost target = new HttpHost("10.10.100.102:8080/mytest", 8080,  

                "http");  

        // 依次是代理地址，代理端口号，协议类型  

        HttpHost proxy = new HttpHost("yourproxy", 8080, "http");  

        RequestConfig config = RequestConfig.custom().setProxy(proxy).build();  

  

        // 请求地址  

        HttpPost httpPost = new HttpPost("http://10.10.100.102:8080/mytest");  

        httpPost.setConfig(config);  

        // 创建参数队列  

        List<NameValuePair> formparams = new ArrayList<NameValuePair>();  

        // 参数名为pid，值是2  

        formparams.add(new BasicNameValuePair("pid", "2"));  

  

        UrlEncodedFormEntity entity;  

        try {  

            entity = new UrlEncodedFormEntity(formparams, "UTF-8");  

            httpPost.setEntity(entity);  

            CloseableHttpResponse response = closeableHttpClient.execute(  

                    target, httpPost);  

            // getEntity()  

            HttpEntity httpEntity = response.getEntity();  

            if (httpEntity != null) {  

                // 打印响应内容  

                System.out.println("response:"  

                        + EntityUtils.toString(httpEntity, "UTF-8"));  

            }  

            // 释放资源  

            closeableHttpClient.close();  

        } catch (Exception e) {  

            e.printStackTrace();  

        }  

    }  

}
