HttpComponents实战

注册某论坛，对新人限制非常多，处处不便。

看到可以通过邀请注册快速活动经验，动起主意，想通过程序快速注册多个帐号来获取经验。

试验发现，单ip720小时内只能注册一个帐号，虽说可以不断重启路由来重新获得ip但还嫌麻烦。

想到平常用的 GAE 翻墙，google的代理服务器肯定很多，一定有很多不同的ip。

开始尝试 httpcomponents通过GAE代理连接 ip138，获取到美国ip则说明代理成功。

1.本地 GAE代理服务开好（具体方法搜“GAE翻@墙”）

2.代码

[java] view plaincopy

package com.zhh.examples.client;
import org.apache.http.HttpEntity;
import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.conn.params.ConnRoutePNames;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
public class ProxyDemo {
public static void main(String[] args) throws Exception {
String proxyUrl = "127.0.0.1";
int proxyPort = 8087;
String url = "http://iframe.ip138.com/city.asp";
DefaultHttpClient client = new DefaultHttpClient();
client.getCredentialsProvider().setCredentials(
new AuthScope(proxyUrl, proxyPort),
new UsernamePasswordCredentials("", ""));
HttpHost proxy = new HttpHost(proxyUrl, proxyPort);
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
// 设置代理结束
HttpPost post = new HttpPost(url);
HttpResponse response = client.execute(post);
// 打印出状态码
System.out.println(response.getStatusLine());
HttpEntity entity = response.getEntity();
if (null != entity){
System.out.println("Response content length: " + entity.getContentLength());
System.out.println("Response content:\n" + EntityUtils.toString(entity));
}
}
}

发现返回的网页内容显示美国ip，代理成功。再接再厉。

尝试通过代理注册帐号

[java] view plaincopy

package com.zhh.examples.client;
import java.util.ArrayList;
import java.util.List;
import org.apache.http.Consts;
import org.apache.http.HttpEntity;
import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.conn.params.ConnRoutePNames;
import org.apache.http.cookie.Cookie;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
public class RegDG {
public static void main(String[] args) throws Exception {
String proxyUrl = "127.0.0.1";
int proxyPort = 8087;
String url = "http://www.baidu.com/?a=btpcgo";//baidu为虚拟
DefaultHttpClient client = new DefaultHttpClient(new ThreadSafeClientConnManager());
//设置代理
client.getCredentialsProvider().setCredentials(
new AuthScope(proxyUrl, proxyPort),
new UsernamePasswordCredentials("", ""));
HttpHost proxy = new HttpHost(proxyUrl, proxyPort);
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
//请求url 使a=btpcgo存入cookie 注册时服务端会检测是哪个用户邀请
HttpGet get = new HttpGet(url);
HttpResponse response = client.execute(get);
System.out.println(response.getStatusLine());
HttpEntity entity = response.getEntity();
if (null != entity){
System.out.println("Response content length: " + entity.getContentLength());
// System.out.println("Response content:\n" + EntityUtils.toString(entity));
}
//查看cookies值
List<Cookie> cookies = client.getCookieStore().getCookies();
if (null != cookies){
for (Cookie cookie:cookies){
System.out.println(cookie.getName()+" - " + cookie.getValue());
}
}
//注册
String regUrl = "http://www.baidu.com/register.php";
String regName = "test" + (int)(Math.random()*100000);
String regPwd = "12345679";
String regEmail = regName + "@163.com";
System.out.println("=============Register===============" + regName);
HttpPost regPost = new HttpPost(regUrl);
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("forward", ""));
nvps.add(new BasicNameValuePair("step", "2"));
nvps.add(new BasicNameValuePair("_hexie", "a3fb2f2b"));
nvps.add(new BasicNameValuePair("regname", regName));
nvps.add(new BasicNameValuePair("regpwd", regPwd));
nvps.add(new BasicNameValuePair("regpwdrepeat", regPwd));
nvps.add(new BasicNameValuePair("regemail", regEmail));
nvps.add(new BasicNameValuePair("rgpermit", "1"));
regPost.setEntity(new UrlEncodedFormEntity(nvps, Consts.UTF_8));
HttpResponse response_reg = client.execute(regPost);
HttpEntity regEntity = response_reg.getEntity();
System.out.println(response_reg.getStatusLine());
if (null != regEntity) {
String content = new String(EntityUtils.toString(regEntity).getBytes("iso-8859-1"), "gbk");
System.out.println("Response content:\n" + content);
}
client.getConnectionManager().shutdown();
}
}

运行发现注册成功！GAE服务器ip大概一分钟最自动更换，大概是选择自动选择最空闲的服务器，但总共大概只有上百个ip来回用，不方便大量刷。
如果有大量代理服务器，可以依次替换不同代理服务器注册，效率更高。

对于注册有验证码的，可以使用 "Tesseract-ocr" 或 “tesseract” 来自动识别验证码，对一般验证码还是相当有把握的。
