Cross-domain Access

For security reasons, direct cross-domain access is not allowed, and here are two ways to cross-domain.

one, via PHP curl

1 functionCurlpost ($url,$params)2 {3  $postData= ' ';4  foreach($params  as $k=$v)5  {6  $postData.=$k. ' = '.$v.‘ & ';7  }8  RTrim($postData, ' & ');9  $ch=curl_init ();Tencurl_setopt ($ch, Curlopt_url,$url); Onecurl_setopt ($ch, Curlopt_returntransfer,true); A  -curl_setopt ($ch, Curlopt_header,false); -curl_setopt ($ch, Curlopt_post,Count($postData)); thecurl_setopt ($ch, Curlopt_postfields,$postData);  -  -  $output=curl_exec ($ch); -  +Curl_close ($ch); -  return $output; + } A  at EchoCurlpost ("http://test.com",Array(' name ' = "Tank"));

A lot of people used curl to catch the email address book, but now it is not possible. Ha ha.

Two, submit using jquery Form,ajax
