PHP Fsockopen Imitation post and get detailed

If you want to use the Fsockopen function we must set the Allow_url_fopen = on in the php.ini to the open state.

Cases

Fsockopen () Example

code is as follows	copy code
<?php $fp = Fsockopen ("www.example.com", $errno, $errstr, 30); if (! $fp) {     echo $errstr ($errno) <br/>n "; } else {     $out =" Get/http/1.1rn ";     $out. = "HOST:WWW.EXAMPLE.COMRN";     $out. = "Connection:closernrn";     fwrite ($fp, $out);     while (!feof ($fp)) {         echo fgets ($FP, 128); & nbsp;  }     fclose ($fp); } ?

Forged Post

POST http request (URL) and get the return value

The code is as follows

Copy Code

<?php $srv _ip = ' 192.168.1.5 ';//your target service address. $srv _port = 80;//Port $url = ' http://localhost/fsock.php '; Receive the URL specific address of your post $fp = '; $errno = 0;//error Handling $errstr = ';//error handling $timeout = How long has 10;//been interrupted without a connection? $post _str = "Username=demo&password=hahaha";//what to submit. Open the Socket link for the network. $fp = Fsockopen ($srv _ip, $srv _port, $errno, $errstr, $timeout); if (! $fp) { Echo (' FP fail '); } $content _length = strlen ($post _str); $post _header = "Post $url http/1.1rn"; $post _header. = "CONTENT-TYPE:APPLICATION/X-WWW-FORM-URLENCODEDRN"; $post _header. = "User-agent:msiern"; $post _header. = "Host:". $srv _ip. " RN "; $post _header. = "Content-length:". $content _length. " RN "; $post _header. = "Connection:closernrn"; $post _header. = $post _str. " Rnrn "; Fwrite ($fp, $post _header); $inheader = 1; while (!feof ($fp)) {//test file pointer to location at end of file $line = fgets ($fp, 1024); Remove header information from the request package if ($inheader && ($line = = "N" | | | $line = = "RN")) { $inheader = 0; } if ($inheader = = 0) { Echo $line; } } Fclose ($FP); Unset ($line); ?>

Brief description: The second line of code is your IP address or domain name, the fourth line is the specific address of the page you want to post, this example uses the fsock.php,fsock.php content as follows:

The code is as follows	Copy Code
