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  

1. import java.util.ArrayList;  
2. import java.util.List;  
3.   
4. import org.apache.http.HttpEntity;  
5. import org.apache.http.HttpHost;  
6. import org.apache.http.NameValuePair;  
7. import org.apache.http.client.config.RequestConfig;  
8. import org.apache.http.client.entity.UrlEncodedFormEntity;  
9. import org.apache.http.client.methods.CloseableHttpResponse;  
10. import org.apache.http.client.methods.HttpPost;  
11. import org.apache.http.impl.client.CloseableHttpClient;  
12. import org.apache.http.impl.client.HttpClientBuilder;  
13. import org.apache.http.message.BasicNameValuePair;  
14. import org.apache.http.util.EntityUtils;  
15.   
16. public class HttpClientTest {  
17.     public static void main(String args[]) throws Exception {  
18.         // 创建HttpClientBuilder  
19.         HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();  
20.         // HttpClient  
21.         CloseableHttpClient closeableHttpClient = httpClientBuilder.build();  
22.         // 依次是目标请求地址，端口号,协议类型  
23.         HttpHost target = new HttpHost("10.10.100.102:8080/mytest", 8080,  
24.                 "http");  
25.         // 依次是代理地址，代理端口号，协议类型  
26.         HttpHost proxy = new HttpHost("yourproxy", 8080, "http");  
27.         RequestConfig config = RequestConfig.custom().setProxy(proxy).build();  
28.   
29.         // 请求地址  
30.         HttpPost httpPost = new HttpPost("http://10.10.100.102:8080/mytest");  
31.         httpPost.setConfig(config);  
32.         // 创建参数队列  
33.         List<NameValuePair> formparams = new ArrayList<NameValuePair>();  
34.         // 参数名为pid，值是2  
35.         formparams.add(new BasicNameValuePair("pid", "2"));  
36.   
37.         UrlEncodedFormEntity entity;  
38.         try {  
39.             entity = new UrlEncodedFormEntity(formparams, "UTF-8");  
40.             httpPost.setEntity(entity);  
41.             CloseableHttpResponse response = closeableHttpClient.execute(  
42.                     target, httpPost);  
43.             // getEntity()  
44.             HttpEntity httpEntity = response.getEntity();  
45.             if (httpEntity != null) {  
46.                 // 打印响应内容  
47.                 System.out.println("response:"  
48.                         + EntityUtils.toString(httpEntity, "UTF-8"));  
49.             }  
50.             // 释放资源  
51.             closeableHttpClient.close();  
52.         } catch (Exception e) {  
53.             e.printStackTrace();  
54.         }  
55.     }  
56. }
