1.通过curl函数

$post_data = array();

$post_data['clientname'] = "test08";

$post_data['clientpasswd'] = "test08";

$post_data['submit'] = "submit";

$url='http://xxx.xxx.xxx.xx/xx/xxx/top.php';

$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.txt');

curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

$result = curl_exec($ch);

2.通过fsockopen

$URL=‘http://xxx.xxx.xxx.xx/xx/xxx/top.php';

$post_data['clientname'] = "test08";

$post_data['clientpasswd'] = "test08";

$post_data['submit'] = "ログイン";

$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 $data

foreach($post_data as $key=>$value)

$values[]="$key=".urlencode($value);

$data_string=implode("&",$values);

// 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";

$request.="Content-length: ".strlen($data_string)."\n";

$request.="Connection: close\n";

$request.="\n";

$request.=$data_string."\n";

$fp = fsockopen($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。

<？PHP

/************************************************************************

Name: POST 测试程序

Vesion: 1.0 Date: 2004-08-05

*************************************************************************/

$flag = 0;

//要post的数据

$argv = array(

'var1'=>'abc',

'var2'=>'你好吗');

//构造要post的字符串

foreach ($argv as $key=>$value) {

if ($flag!=0) {

$params .= "&";

$flag = 1;

}

$params.= $key."="; $params.= urlencode($value);

$flag = 1;

}

$length = strlen($params);

//创建socket连接

$fp = fsockopen("127.0.0.1",80,$errno,$errstr,10) or exit($errstr."--->".$errno);

//构造post请求的头

$header = "POST /mobile/try.php HTTP/1.1\r\n";

$header .= "Host:127.0.0.1\r\n";

$header .= "Referer:/mobile/sendpost.php\r\n";

$header .= "Content-Type: application/x-www-form-urlencoded\r\n";

$header .= "Content-Length: ".$length."\r\n";

$header .= "Connection: Close\r\n\r\n";

//添加post的字符串

$header .= $params."\r\n";

//发送post的数据

fputs($fp,$header);

$inheader = 1;

while (!feof($fp)) {

$line = fgets($fp,1024); //去除请求包的头只显示页面的返回数据

if ($inheader && ($line == "\n" || $line == "\r\n")) {

$inheader = 0;

}

if ($inheader == 0) {

echo $line;

}

}

fclose($fp);

?>

还可以使用php类HttpClient
