copy code

$curlPost = ' a=1&b=2 ';//analog post data $ch = Curl_ Init (); curl_setopt ($ch, Curlopt_httpheader, Array (' x-forwarded-for:0.0.0.0 ', ' client-ip:0.0.0.0 '));//Construction IP Curl_ Setopt ($ch, Curlopt_referer, "http://www.bkjia.com/"); Construct the route curl_setopt ($ch, Curlopt_url, ' http://www.bkjia.com ');//page path to crawl curl_setopt ($ch, Curlopt_ Returntransfer, 1); curl_setopt ($ch, Curlopt_timeout, 30); curl_setopt ($ch, Curlopt_postfields, $curlPost);//post value $file _contents = curl_exec ($ch);//The contents of the crawl are placed in the variable curl_close ($ch)
