httpclient4.3 设置代理请求

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();
         }
     }
 }
