Snoopy是什么? （下載snoopy）
Snoopy是一個php類，用來模仿web瀏覽器的功能，它能完成獲取網(wǎng)頁內(nèi)容和發(fā)送表單的任務(wù)。
Snoopy的一些特點:
* 方便抓取網(wǎng)頁的內(nèi)容
* 方便抓取網(wǎng)頁的文本內(nèi)容 (去除HTML標(biāo)簽)
* 方便抓取網(wǎng)頁的鏈接
* 支持代理主機
* 支持基本的用戶名/密碼驗證
* 支持設(shè)置 user_agent, referer(來路), cookies 和 header content(頭文件)
* 支持瀏覽器轉(zhuǎn)向，并能控制轉(zhuǎn)向深度
* 能把網(wǎng)頁中的鏈接擴展成高質(zhì)量的url(默認(rèn))
* 方便提交數(shù)據(jù)并且獲取返回值
* 支持跟蹤HTML框架(v0.92增加)
* 支持再轉(zhuǎn)向的時候傳遞cookies (v0.92增加)
要想了解的更深入些，你自己Google一下吧。下面就給幾個簡單的例子：
1獲取指定url內(nèi)容
PHP代碼

復(fù)制代碼 代碼如下:

$url = "http://m.survivalescaperooms.com";
include("snoopy.php");
$snoopy = new Snoopy;
$snoopy->fetch($url); //獲取所有內(nèi)容
echo $snoopy->results; //顯示結(jié)果
$snoopy->fetchtext //獲取文本內(nèi)容（去掉html代碼）
$snoopy->fetchlinks //獲取鏈接
$snoopy->fetchform //獲取表單

復(fù)制代碼 代碼如下:

$formvars["username"] = "admin";
$formvars["pwd"] = "admin";
$action = "http://m.survivalescaperooms.com";//表單提交地址
$snoopy->submit($action,$formvars);//$formvars為提交的數(shù)組
echo $snoopy->results; //獲取表單提交后的 返回的結(jié)果
$snoopy->submittext; //提交后只返回 去除html的 文本
$snoopy->submitlinks;//提交后只返回 鏈接

復(fù)制代碼 代碼如下:

$formvars["username"] = "admin";
$formvars["pwd"] = "admin";
$action = "http://m.survivalescaperooms.com";
include "snoopy.php";
$snoopy = new Snoopy;
$snoopy->cookies["PHPSESSID"] = 'fc106b1918bd522cc863f36890e6fff7'; //偽裝sessionid
$snoopy->agent = "(compatible; MSIE 4.01; MSN 2.5; AOL 4.0; Windows 98)"; //偽裝瀏覽器
$snoopy->referer = "http://s.vevb.com"; //偽裝來源頁地址 http_referer
$snoopy->rawheaders["Pragma"] = "no-cache"; //cache 的http頭信息
$snoopy->rawheaders["X_FORWARDED_FOR"] = "127.0.0.101"; //偽裝ip
$snoopy->submit($action,$formvars);
echo $snoopy->results;

復(fù)制代碼 代碼如下:

$snoopy->proxy_host = "m.survivalescaperooms.com";
$snoopy->proxy_port = "8080"; //使用代理
$snoopy->maxredirs = 2; //重定向次數(shù)
$snoopy->expandlinks = true; //是否補全鏈接 在采集的時候經(jīng)常用到
// 例如鏈接為 /images/taoav.gif 可改為它的全鏈接 ，這個地方其實可以在最后輸出的時候用ereg_replace函數(shù)自己替換
$snoopy->maxframes = 5 //允許的最大框架數(shù)
//注意抓取框架的時候 $snoopy->results 返回的是一個數(shù)組
$snoopy->error //返回報錯信息

復(fù)制代碼 代碼如下:

<?
//echo var_dump($_SERVER);
include("Snoopy.class.php");
$snoopy = new Snoopy;
$snoopy->agent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-
CN; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5 FirePHP/0.2.1";//這項是瀏覽器信
息，前面你用什么瀏覽器查看cookie，就用那個瀏覽器的信息(ps:$_SERVER可以查看到瀏覽器的信息)
$snoopy->referer = "http://bbs.vevb.com/index.php";
$snoopy->expandlinks = true;
$snoopy->rawheaders["COOKIE"]="__utmz=17229162.1227682761.29.7.utmccn=(referral)|utmcsr=vevb.com|utmcct=/html/index.html|utmcmd=referral; cdbphpchina_smile=1D2D0D1; cdbphpchina_cookietime=2592000; __utma=233700831.1562900865.1227113506.1229613449.1231233266.16; __utmz=233700831.1231233266.16.8.utmccn=(referral)|utmcsr=localhost:8080|utmcct=/test3.php|utmcmd=referral; __utma=17229162.1877703507.1227113568.1231228465.1231233160.58; uchome_loginuser=sinopf; xscdb_cookietime=2592000; __utmc=17229162; __utmb=17229162; cdbphpchina_sid=EX5w1V; __utmc=233700831; cdbphpchina_visitedfid=17; cdbphpchinaO766uPYGK6OWZaYlvHSuzJIP22VpwEMGnPQAuWCFL9Fd6CHp2e%2FKw0x4bKz0N9lGk; xscdb_auth=8106rAyhKpQL49eMs%2FyhLBf3C6ClZ%2B2idSk4bExJwbQr%2BHSZrVKgqPOttHVr%2B6KLPg3DtWpTMUI4ttqNNVpukUj6ElM; cdbphpchina_onlineusernum=3721";
