Current curl code:

$ Url = 'http: // www.cf588.com/forum.php? Mod = viewthread & tid = 145 & extra = page % 3D1 ';

$ Ch = curl_init ();
Curl_setopt ($ ch, CURLOPT_URL, $ url );
Curl_setopt ($ ch, CURLOPT_HEADER, 0 );
Curl_setopt ($ ch, CURLOPT_FOLLOWLOCATION, true );
Curl_setopt ($ ch, CURLOPT_USERAGENT, $ u );
Curl_setopt ($ ch, CURLOPT_REFERER, $ r );
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 );
$ Output = curl_exec ($ ch );

Each capture is: Sorry, the specified topic does not exist, has been deleted, or is being reviewed

Use a browser to open it normally. use fiddle to directly raw:
GET http: // www.cf588.com/forum.php? Mod = viewthread & tid = 145 & extra = page % 3D1 HTTP/1.1
Host: www.cf588.com

It can also be obtained normally. it's depressing. there's nothing wrong with it. Give me some advice.
