1.通过curl函数
$post_da
$post_da
$post_da
$post_da
$url='http://xxx.xxx.xxx.xx/xx/xxx/top.php';
$o="";
foreach ($post_da
{
$o.= "$k=".urlencode($v)."&";
}
$post_da
$ch = curl_init();
curl_setopt($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.txt');
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_da
$result = curl_exec($ch);
2.通过fsockopen
$URL=‘http://xxx.xxx.xxx.xx/xx/xxx/top.php';
$post_da
$post_da
$post_da
$referrer="";
// parsing the given URL
$URL_Info=parse_url($URL);
// Building referrer
if($referrer=="") // if not given use this script as referrer
$referrer=$_SERVER["SCRIPT_URI"];
// making string from $da
foreach($post_da
$values[]="$key=".urlencode($value);
$da
// Find out which port is needed - if not given use standard (=80)
if(!isset($URL_Info["port"]))
$URL_Info["port"]=80;
// building POST-request:
$request.="POST ".$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";
$request.="Content-length: ".strlen($da
$request.="Connection: close\n";
$request.="\n";
$request.=$da
$fp = fsockopen($URL_Info["host"],$URL_Info["port"]);
fputs($fp, $request);
while(!feof($fp)) {
$result .= fgets($fp, 128);
}
fclose($fp);
用php模拟post来提交数据
利用php的socket编程来直接给接口发送数据来模拟post的操作。

$flag = 0;

//发送post的数据
fputs($fp,$header);

if ($inheader && ($line == "\n" || $line == "\r\n")) {
$inheader = 0;
}
if ($inheader == 0) {
echo $line;
}
