PHP 模拟 Post 的两种方法

function poster()
{
$URL = 'http://www.yw56.com.cn/DIY.asp'; //需要提交到的页面
//下面这段是要提交的数据
$post_data['orderid'] = "YW861736303CN";
$post_data['button'] = "提交";

$referrer="http://www.yw56.com.cn/DIY.asp";
$Cookie="ASPSESSIONIDQASTTQBC=NCCPADLCAKFNICPOABDAFHOP";
$URL_Info=parse_url($URL);
if($referrer=="")
{
$referrer=$_SERVER["SCRIPT_URI"];
}
foreach ($post_data as $key=>$value)
{
$values[]="$key=".urlencode($value);
}

$data_string=implode("&",$values);//提交的数据格式是 a=1&b=2
// Find out which port is needed - if not given use standard (=80)
if (!isset($URL_Info["port"])) {
$URL_Info["port"]=80;
// building POST-request:
//一般做网站用form提交数据后，之后的操作就不用我们不管了，
//这里就是在模拟POST操作的HTTP头，具体的可以去查HTTP协议的资料，并不复杂
$request.="POST ".$URL_Info["path"]." HTTP/1.1/n";
$request.="Host: ".$URL_Info["host"]."/n";
$request.="Referer: $referrer/n";
$request.="Content-type: application/x-www-form-urlencoded/n";
$request.="Content-length: ".strlen($data_string)."/n";
$request.="Connection: close/n";
$request.="/n";
$request.=$data_string."/n";
//exit;
}
//fsockopen的用法就这样子了，不做多说明
$fp = fsockopen($URL_Info["host"], $URL_Info["port"]);
fputs($fp, $request);//把HTTP头发送出去
while(!feof($fp)) {
//$result 是提交后返回的数据
$result .= fgets($fp, 1024);
}
fclose($fp);

echo $result;

}

function poster1()
{
$post_data = array();
$post_data['orderid'] = "YW861736303CN";
$post_data['button'] = "提交";
$url='http://www.yw56.com.cn/DIY.asp';
$cookie="ASPSESSIONIDQASTTQBC=NCCPADLCAKFNICPOABDAFHOP";
$o="";
foreach ($post_data as $k=>$v)
{
$o.= "$k=".urlencode($v)."&";
}
$post_data=substr($o,0,-1);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL,$url);
//为了支持cookie
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
$result = curl_exec($ch);

echo $result;

}
