htmlunit使用代理IP

有时候频繁的爬取第三方站点内容，会被站点的防火墙拦截，IP拉黑，所以这时候，就要用到代理IP，拉黑一个就换一个

htmlunit实用代理的方式比较简单，WebClient重载构造方法就有提供

package com.gcx.htmlunit;import java.io.IOException;
import java.net.MalformedURLException;import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.DomElement;
import com.gargoylesoftware.htmlunit.html.DomNodeList;
import com.gargoylesoftware.htmlunit.html.HtmlDivision;
import com.gargoylesoftware.htmlunit.html.HtmlListItem;
import com.gargoylesoftware.htmlunit.html.HtmlPage;public class IpSearch {public static void main(String[] args) {//实例化web客户端 模拟指定浏览器WebClient wc=new WebClient(BrowserVersion.FIREFOX_52,"60.2.148.253",80);try {//解析获取页面HtmlPage page = wc.getPage("https://www.baidu.com");//获取htmlSystem.out.println("网页:"+page.asXml());} catch (FailingHttpStatusCodeException e) {e.printStackTrace();} catch (MalformedURLException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();wc.close();//关闭客户端，释放资源}}
}
