通过Snoopy运行一个简单的php网络爬虫 - http://turma.sourceforge.net/web/urlator/snoopy.html - 但是Fetchlinks()函数有点问题。通常,fetchlinks()会抓取页面上的所有链接并将它们很好地插入到数组中。这适用于所有http://链接,但任何https://链接都被添加到http://链接,并且不会放在数组中自己的插槽中。
损坏的https链接示例:
[472] => http://www.vapetropolis.ca/returns/https://www.vapetropolis.ca/product-warranties [473] => http://www.vapetropolis.ca/vaporizer-parts/davinci-vaporizer/https://www.vapetropolis.ca/product-warranties/https://www.vapetropolis.ca/customer/account/
正如您所看到的,他们已经被正确地形成了http://链接。
这是产生此
的代码 function crawl_link($link, array &$sitewide_link_list) {
$snoopy = new Snoopy;
//Get all links from first page
$snoopy->fetchlinks($link);
$currPage = $snoopy->results;
//Add all links to global array
//First, filter the links
//Ensure all links are from correct domain
$parsedDomain = 'www.vapetropolis.ca';
if (is_array($currPage)) {
foreach ($currPage as $link) {
if ($parsedDomain == parse_url( $link, PHP_URL_HOST )) {
if (!in_array($link, $sitewide_link_list)) {
array_push($sitewide_link_list, $link);
}
}
}
}
}
//Start crawl
//Global array of links
$sitewide_link_list = array();
$checkList = array();
$done = false;
$domain = 'http://www.vapetropolis.ca';
crawl_link($domain, $sitewide_link_list);
print_r($sitewide_link_list);
有什么线索可能会发生什么?
