在使用curl采集或訪問網(wǎng)頁時,有時需要提供一些header頭部信息。這需要用到curl的CURLOPT_HTTPHEADER。
下面是一個手冊案例:
function disguise_curl($url) { $curl = curl_init(); // Setup headers - I used the same headers from Firefox version 2.0.0.6 // below was split up because php.net said the line was too long. :/ $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,"; $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; $header[] = "Cache-Control: max-age=0"; $header[] = "Connection: keep-alive"; $header[] = "Keep-Alive: 300"; $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"; $header[] = "Accept-Language: en-us,en;q=0.5"; $header[] = "Pragma: "; // browsers keep this blank. curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_USERAGENT, 'Googlebot/2.1 (+http://www.google.com/bot.html)'); curl_setopt($curl, CURLOPT_HTTPHEADER, $header); curl_setopt($curl, CURLOPT_REFERER, 'http://www.google.com'); curl_setopt($curl, CURLOPT_ENCODING, 'gzip,deflate'); curl_setopt($curl, CURLOPT_AUTOREFERER, true); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_TIMEOUT, 10); $html = curl_exec($curl); // execute the curl command curl_close($curl); // close the connection return $html; // and finally, return $html }
上面的案例中,偽造了一個假的google來源。
如果你需要提供一個IP,比如采集時需要偽造一個假IP。那么可以傳遞這兩個頭部信息:
$header = array(
'CLIENT-IP:假的IP',
'X-FORWARDED-FOR:假的IP',
);
