這篇文章主要介紹PHPCrawl爬蟲庫如何抓取酷狗歌單,文中介紹的非常詳細,具有一定的參考價值,感興趣的小伙伴們一定要看完!
具體如下:
本人看了網絡爬蟲相關的視頻后,手癢癢,想爬點什么。最近Facebook上表情包大戰很激烈,就想著把所有表情包都爬下來,卻一時沒有找到合適的VPN,因此把酷狗最近一月精選歌曲和簡單介紹抓取到本地。代碼寫得有點亂,自己不是很滿意,并不想放上來丟人現眼。不過轉念一想,這好歹是自己第一次爬蟲,于是...就有了如下不堪入目的代碼~~~(由于抓取的數據量較小,所以沒有考慮多進程什么的,不過我看了一下PHPCrawl的文檔,發現PHPCrawl庫已經把我能想到的功能都封裝好了,實現起來很方便)
<?php header("Content-type:text/html;charset=utf-8"); // It may take a whils to crawl a site ... set_time_limit(10000); include("libs/PHPCrawler.class.php"); class MyCrawler extends PHPCrawler { function handleDocumentInfo($DocInfo) { // Just detect linebreak for output ("\n" in CLI-mode, otherwise "<br>"). if (PHP_SAPI == "cli") $lb = "\n"; else $lb = "<br />"; $url = $DocInfo->url; $pat = "/http:\/\/www\.kugou\.com\/yy\/special\/single\/\d+\.html/"; if(preg_match($pat,$url) > 0){ $this->parseSonglist($DocInfo); } flush(); } public function parseSonglist($DocInfo){ $content = $DocInfo->content; $songlistArr = array(); $songlistArr['raw_url'] = $DocInfo->url; //解析歌曲介紹 $matches = array(); $pat = "/<span>名稱:<\/span>([^(<br)]+)<br/"; $ret = preg_match($pat,$content,$matches); if($ret>0){ $songlistArr['title'] = $matches[1]; }else{ $songlistArr['title'] = ''; } //解析歌曲 $pat = "/<a title=\"([^\"]+)\" hidefocus=\"/"; $matches = array(); preg_match_all($pat,$content,$matches); $songlistArr['songs'] = array(); for($i = 0;$i < count($matches[0]);$i++){ $song_title = $matches[1][$i]; array_push($songlistArr['songs'],array('title'=>$song_title)); } echo "<pre>"; print_r($songlistArr); echo "</pre>"; } } $crawler = new MyCrawler(); // URL to crawl $start_url="http://www.kugou.com/yy/special/index/1-0-2.html"; $crawler->setURL($start_url); // Only receive content of files with content-type "text/html" $crawler->addContentTypeReceiveRule("#text/html#"); //鏈接擴展 $crawler->addURLFollowRule("#http://www\.kugou\.com/yy/special/single/\d+\.html$# i"); $crawler->addURLFollowRule("#http://www.kugou\.com/yy/special/index/\d+-\d+-2\.html$# i"); // Store and send cookie-data like a browser does $crawler->enableCookieHandling(true); // Set the traffic-limit to 1 MB(1000 * 1024) (in bytes, // for testing we dont want to "suck" the whole site) //爬取大小無限制 $crawler->setTrafficLimit(0); // Thats enough, now here we go $crawler->go(); // At the end, after the process is finished, we print a short // report (see method getProcessReport() for more information) $report = $crawler->getProcessReport(); if (PHP_SAPI == "cli") $lb = "\n"; else $lb = "<br />"; echo "Summary:".$lb; echo "Links followed: ".$report->links_followed.$lb; echo "Documents received: ".$report->files_received.$lb; echo "Bytes received: ".$report->bytes_received." bytes".$lb; echo "Process runtime: ".$report->process_runtime." sec".$lb; ?>
