我们经常会听人说利用php模拟用户发送post数据,今天出于好奇我找了两个用不同方法来实例post数据的方法，有需要了解的朋友可以看看.
使用 php 向页面 post 数据
| 代码如下 | 复制代码 |
|
function socketPost($url, $data, &$ret) { $urlArr = parse_url($url); $host = $urlArr['host']; $port = isset($urlArr['port'])?$urlArr['port']:80; $path = isset($urlArr['path'])?$urlArr['path']:"/"; $fp = fsockopen($host, $port, $errno, $errstr, 30); if (!$fp) { echo "$errstr ($errno) n"; return false; } else { $out = "POST $path HTTP/1.1rn"; $out .= "Host: $hostrn"; $out .= "Content-Type: application/x-www-form-urlencodedrn"; $out .= "Content-Length: ".strlen($data)."rn"; $out .= "Connection: Keep-Alivernrn"; $out .= $data; $ret = ""; fwrite($fp, $out); while (!feof($fp)) { $ret .= fgets($fp, 128); } fclose($fp); } return true; } ?> |
|
如果post报错，把$out .= "Connection: Keep-Alivernrn";中的Keep-Alive改成Close
利用php的socket模拟发送post数据的一个实例
| 代码如下 | 复制代码 |
|
$domain = "127.0.0.1"; $port = 80; $uri = "/ly/post.php"; $data="txtName=111&txtEmail=222@1.net&rabSex=%D0%A1%BD%E3&txtFrom=%BD%AD%CE%F7%C1%FA%C4%CF&txtQq=2222&txtUrl=33333333&txtFace=images%2Fface%2Fface05.gif&txtEm=images%2Fem%2Fem01.gif&txtBody=rrr"; $protocolstr ="POST {$uri} HTTP/1.1rnHost: {$domain}rnContent-type: application/x-www-form-urlencodedrnContent-length: " . strlen($data) . "rnReferer: http://10.10.10.10/ly/index.phprnUser-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322)rnAccept: */*rnrn{$data}rnrn"; $sock = fsockopen($domain, $port, $errno, $errstr, 30); if (!$sock) die("$errstr ($errno)n"); fputs($sock, $protocolstr); $headers = ""; while ($str = trim(fgets($sock, 4096))) $headers .= "$strn"; $body = ""; while (!feof($sock)) $body .= fgets($sock, 4096); fclose($sock); echo " Response header:n";echo $headers; echo "n"; echo " Response body:n";echo $body; ?> |

在这里我们就不讲关于fsockopen fwrite这些函数的用法了，只讲述模仿过程，有需要的可参考了下。
