HttpClient使用代理IP

那代理IP 从哪里搞呢 很简单  百度一下，你就知道 一大堆代理IP站点。  一般都会给出一些免费的，但是花点钱搞收费接口更加方便；

比如 http://www.66ip.cn/

package com.open1111.httpclient.chap04;

 

 

import org.apache.http.HttpEntity;

import org.apache.http.HttpHost;

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

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

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

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

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

import org.apache.http.util.EntityUtils;

 

public class Demo1 {

 

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

        CloseableHttpClient httpClient=HttpClients.createDefault(); // 创建httpClient实例

        HttpGet httpGet=new HttpGet("https://www.taobao.com/"); // 创建httpget实例

        HttpHost proxy=new HttpHost("116.226.217.54", 9999);

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

        httpGet.setConfig(requestConfig);

        httpGet.setHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0");

        CloseableHttpResponse response=httpClient.execute(httpGet); // 执行http get请求

        HttpEntity entity=response.getEntity(); // 获取返回实体

        System.out.println("网页内容："+EntityUtils.toString(entity, "utf-8")); // 获取网页内容

        response.close(); // response关闭

        httpClient.close(); // httpClient关闭

    }

}
