本文实例讲述了PHP中Snoopy类用法。分享给大家供大家参考。具体分析如下：
这里演示了PHP中如何通过Snoopy抓取网页信息
snoopy类的下载地址：http://sourceforge.net/projects/snoopy/
proxy_host = "my.proxy.host";
//$snoopy->proxy_port = "8080";
// set browser and referer:
$snoopy->agent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)";
$snoopy->referer = "http://www.jonasjohn.de/";
// set some cookies:
$snoopy->cookies["SessionID"] = '238472834723489';
$snoopy->cookies["favoriteColor"] = "blue";
// set an raw-header:
$snoopy->rawheaders["Pragma"] = "no-cache";
// set some internal variables:
$snoopy->maxredirs = 2;
$snoopy->offsiteok = false;
$snoopy->expandlinks = false;
// set username and password (optional)
//$snoopy->user = "joe";
//$snoopy->pass = "bloe";
// fetch the text of the website www.google.com:
if($snoopy->fetchtext("http://www.google.com")){
// other methods: fetch,fetchform,fetchlinks,submittext and submitlinks
// response code:
print "response code: ".$snoopy->response_code."
\n"; // print the headers: print "Headers:
"; while(list($key,$val) = each($snoopy->headers)){ print $key.": ".$val."
\n"; } print "
\n";
}
else {
print "Snoopy: error while fetching document: ".$snoopy->error."\n";
}
\n"; // print the headers: print "Headers:
"; while(list($key,$val) = each($snoopy->headers)){ print $key.": ".$val."
\n"; } print "
\n";
// print the texts of the website:
print "
".htmlspecialchars($snoopy->results)."\n";
}
else {
print "Snoopy: error while fetching document: ".$snoopy->error."\n";
}
希望本文所述对大家的PHP程序设计有所帮助。
