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：

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();
		}
	}
}

您好，您知道这么设置以后，如何设置代理服务器的用户名和密码么

好久没搞这个了,手边也没有这个环境,但是我帮你查了一下,请试试

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

BasicScheme proxyAuth = new BasicScheme();
// Make client believe the challenge came form a proxy
proxyAuth.processChallenge(new BasicHeader(AUTH.PROXY_AUTH, "BASIC realm=default"));
BasicAuthCache authCache = new BasicAuthCache();
authCache.put(proxy, proxyAuth);

CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
        new AuthScope(proxy),
        new UsernamePasswordCredentials("username", "password"));

HttpClientContext context = HttpClientContext.create();
context.setAuthCache(authCache);
context.setCredentialsProvider(credsProvider);

CloseableHttpClient httpclient = HttpClients.createDefault();
try {
    CloseableHttpResponse response = httpclient.execute(new HttpGet("/stuff"), context);
    try {
        // ...
    } finally {
        response.close();
    }
} finally {
    httpclient.close();
}
