php 采集snoopy类

来源 /

Snoopy的一些特点:

抓取网页的内容 fetch
抓取网页的文本内容 (去除HTML标签) fetchtext
抓取网页的链接，表单 fetchlinks fetchform
支持代理主机
支持基本的用户名/密码验证
支持设置 user_agent, referer(来路), cookies 和 header content(头文件)
支持浏览器重定向，并能控制重定向深度
能把网页中的链接扩展成高质量的url(默认)
提交数据并且获取返回值
支持跟踪HTML框架
支持重定向的时候传递cookies
要求php4以上就可以了 由于本身是php一个类 无需扩支持 服务器不支持curl时候的最好选择，

Snoopy类方法及示例：

fetch($URI)

这是为了抓取网页的内容而使用的方法。
$URI参数是被抓取网页的URL地址。
抓取的结果被存储在 $this->results 中。
如果你正在抓取的是一个框架，Snoopy将会将每个框架追踪后存入数组中，然后存入 $this->results。

fetchtext($URI)

本方法类似于fetch()，唯一不同的就是本方法会去除HTML标签和其他的无关数据，只返回网页中的文字内容。

fetchform($URI)
本方法类似于fetch()，唯一不同的就是本方法会去除HTML标签和其他的无关数据，只返回网页中表单内容(form)。

fetchlinks($URI)
本方法类似于fetch()，唯一不同的就是本方法会去除HTML标签和其他的无关数据，只返回网页中链接(link)。
默认情况下，相对链接将自动补全，转换成完整的URL。

submit( U R I , URI, URI,formvars)
本方法向 U R L 指 定 的 链 接 地 址 发 送 确 认 表 单 。 URL指定的链接地址发送确认表单。 URL指定的链接地址发送确认表单。formvars是一个存储表单参数的数组。

submittext( U R I , URI, URI,formvars)
本方法类似于submit()，唯一不同的就是本方法会去除HTML标签和其他的无关数据，只返回登陆后网页中的文字内容。

submitlinks($URI)
本方法类似于submit()，唯一不同的就是本方法会去除HTML标签和其他的无关数据，只返回网页中链接(link)。
默认情况下，相对链接将自动补全，转换成完整的URL。

Snoopy采集类属性: (默认值在括号里)

$host 连接的主机
$port 连接的端口
$proxy_host 使用的代理主机，如果有的话
$proxy_port 使用的代理主机端口，如果有的话
$agent 用户代理伪装 (Snoopy v0.1)
$referer 来路信息，如果有的话
$cookies cookies 如果有的话
$rawheaders 其他的头信息, 如果有的话
$maxredirs 最大重定向次数， 0=不允许 (5)
$offsiteok whether or not to allow redirects off-site. (true)
$expandlinks 是否将链接都补全为完整地址 (true)
$user 认证用户名, 如果有的话
$pass 认证用户名, 如果有的话
$accept http 接受类型 (image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, /)
$error 哪里报错, 如果有的话
$response_code 从服务器返回的响应代码
$headers 从服务器返回的头信息
$maxlength 最长返回数据长度
$read_timeout 读取操作超时 (requires PHP 4 Beta 4+) 设置为0为没有超时
$timed_out 如果一次读取操作超时了，本属性返回 true (requires PHP 4 Beta 4+)
$maxframes 允许追踪的框架最大数量
$status 抓取的http的状态
$temp_dir 网页服务器能够写入的临时文件目录 (/tmp)
$curl_path cURL binary 的目录, 如果没有cURL binary就设置为 false

include "Snoopy.class.php";$snoopy = new Snoopy;$snoopy->proxy_host = "";$snoopy->proxy_port = "80";$snoopy->agent = "(compatible; MSIE 4.01; MSN 2.5; AOL 4.0; Windows 98)";$snoopy->referer = "";$snoopy->cookies["SessionID"] = 238472834723489l;$snoopy->cookies["favoriteColor"] = "RED";$snoopy->rawheaders["Pragma"] = "no-cache";$snoopy->maxredirs = 2;$snoopy->offsiteok = false;$snoopy->expandlinks = false;$snoopy->user = "joe";$snoopy->pass = "bloe";if($snoopy->fetchtext("")){echo "<PRE>".htmlspecialchars($snoopy->results)."</PRE>n";}elseecho "error fetching document: ".$snoopy->error."n";

获取指定url内容

<?php$url = "";include("snoopy.php");$snoopy = new Snoopy;$snoopy->fetch($url); //获取所有内容echo $snoopy->results; //显示结果//可选以下$snoopy->fetchtext //获取文本内容（去掉html代码）$snoopy->fetchlinks //获取链接$snoopy->fetchform  //获取表单?>

表单提交

<?php$formvars["username"] = "admin";$formvars["pwd"] = "admin";$action = "";//</a>表单提交地址$snoopy->submit($action,$formvars);//$formvars为提交的数组echo $snoopy->results; //获取表单提交后的 返回的结果//可选以下$snoopy->submittext; //提交后只返回 去除html的 文本$snoopy->submitlinks;//提交后只返回 链接?>

既然已经提交的表单 那就可以做很多事情 接下来我们来伪装ip,伪装浏览器
伪装浏览器

<?php$formvars["username"] = "lanfengye";$formvars["pwd"] = "lanfengye";$action = "";include "snoopy.php";$snoopy = new Snoopy;$snoopy->cookies["PHPSESSID"] = 'fc106b1918bd522cc863f36890e6fff7'; //伪装sessionid$snoopy->agent = "(compatible; MSIE 4.01; MSN 2.5; AOL 4.0; Windows 98)"; //伪装浏览器$snoopy->referer = ""; //伪装来源页地址 http_referer$snoopy->rawheaders["Pragma"] = "no-cache"; //cache 的http头信息$snoopy->rawheaders["X_FORWARDED_FOR"] = "127.0.0.101"; //伪装ip$snoopy->submit($action,$formvars);echo $snoopy->results;?>

原来我们可以伪装session 伪装浏览器 ，伪装ip， haha 可以做很多事情了。
例如 带验证码，验证ip 投票， 可以不停的投。
ps:这里伪装ip ，其实是伪装http头, 所以一般的通过 REMOTE_ADDR 获取的ip是伪装不了，
反而那些通过http头来获取ip的(可以防止代理的那种) 就可以自己来制造ip。
关于如何验证码 ，简单说下：
首先用普通的浏览器， 查看页面 ， 找到验证码所对应的sessionid，
同时记下sessionid和验证码值，
接下来就用snoopy去伪造 。
原理:由于是同一个sessionid 所以取得的验证码和第一次输入的是一样的。

有时我们可能需要伪造更多的东西,snoopy完全为我们想到了

<?php
$snoopy->proxy_host = "";
$snoopy->proxy_port = "8080"; //使用代理
$snoopy->maxredirs = 2; //重定向次数
$snoopy->expandlinks = true; //是否补全链接 在采集的时候经常用到
// 例如链接为 /images/taoav.gif 可改为它的全链接 <a href=".gif">.gif</a>
$snoopy->maxframes = 5 //允许的最大框架数
//注意抓取框架的时候 $snoopy->results 返回的是一个数组
$snoopy->error //返回报错信息
?>
