Penyelesaian kepada masalah PHP CURL mengumpul imej hasil carian Baidu tidak dipaparkan
1 Kumpul hasil carian Baidu berdasarkan kata kunci
Berdasarkan pengumpulan kata kunci hasil carian Baidu boleh dicapai menggunakan curl Kod adalah seperti berikut:
<p><?php <br/>function doCurl($url, $data=array(), $header=array(), $timeout=30){<br> $ch = curl_init();<br> curl_setopt($ch, CURLOPT_URL, $url);<br> curl_setopt($ch, CURLOPT_HTTPHEADER, $header);<br> curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);<br> curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);<br> curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);<br> $response = curl_exec($ch);<br> if($error=curl_error($ch)){<br> die($error);<br> }<br> curl_close($ch);<br> return $response;<br>}<br>$wd = '仙剑奇侠传';<br>$url = 'http://www.baidu.com/s?wd='.urlencode($wd);<br>$data = array();<br>$header = array();<br>$response = doCurl($url, $data, $header, 5);<br>echo $response;<br>?><br></p>
Selepas output, didapati beberapa gambar tidak boleh dipaparkan
2. Koleksi Analisis sebab gambar berikut tidak dipaparkan
Cari terus di Baidu, halaman boleh memaparkan gambar. Gunakan pepijat api untuk menyemak laluan imej dan mendapati bahawa nama domain imej yang dikumpul adalah berbeza daripada nama domain imej yang dicari di Baidu.
Kumpulkan nama domain imej yang dikembalikan t11.baidu.com
Nama domain imej carian biasa ss1.baidu.com
Semak html yang dikumpul dan carian biasa, dan mendapati bahawa js untuk penukaran nama domain adalah berbeza
Koleksi
<p>var list = {<br> "graph.baidu.com": "http://graph.baidu.com",<br> "t1.baidu.com":"http://t1.baidu.com",<br> "t2.baidu.com":"http://t2.baidu.com",<br> "t3.baidu.com":"http://t3.baidu.com",<br> "t10.baidu.com":"http://t10.baidu.com",<br> "t11.baidu.com":"http://t11.baidu.com",<br> "t12.baidu.com":"http://t12.baidu.com",<br> "i7.baidu.com":"http://i7.baidu.com",<br> "i8.baidu.com":"http://i8.baidu.com",<br> "i9.baidu.com":"http://i9.baidu.com",<br>};<br></p>
Carian biasa
<p>var list = {<br> "graph.baidu.com": "https://sp0.baidu.com/-aYHfD0a2gU2pMbgoY3K",<br> "t1.baidu.com":"https://ss0.baidu.com/6ON1bjeh1BF3odCf",<br> "t2.baidu.com":"https://ss1.baidu.com/6OZ1bjeh1BF3odCf",<br> "t3.baidu.com":"https://ss2.baidu.com/6OV1bjeh1BF3odCf",<br> "t10.baidu.com":"https://ss0.baidu.com/6ONWsjip0QIZ8tyhnq",<br> "t11.baidu.com":"https://ss1.baidu.com/6ONXsjip0QIZ8tyhnq",<br> "t12.baidu.com":"https://ss2.baidu.com/6ONYsjip0QIZ8tyhnq",<br> "i7.baidu.com":"https://ss0.baidu.com/73F1bjeh1BF3odCf",<br> "i8.baidu.com":"https://ss0.baidu.com/73x1bjeh1BF3odCf",<br> "i9.baidu.com":"https://ss0.baidu.com/73t1bjeh1BF3odCf",<br>};<br></p>
Oleh itu, boleh disimpulkan bahawa Baidu menentukan sama ada ia dikumpul berdasarkan alamat sumber, IP, pengepala dan parameter lain, dan mengembalikan js yang berbeza.
3. Penyelesaian kepada masalah bahawa imej tidak dipaparkan selepas pengumpulan
Hanya lakukan penukaran kumpulan HTML yang dikumpul mengikut nama domain yang ditentukan.
