用PHP模拟POST来提交数据_PHP教程

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;
//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/1.1rn";
$header .= "host:127.0.0.1rn";
$header .= "referer:/mobile/sendpost.phprn";
$header .= "content-type: application/x-www-form-urlencodedrn";
$header .= "content-length: ".$length."rn";
$header .= "connection: closernrn";
//添加post的字符串
$header .= $params."rn";
//发送post的数据
fputs($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 == "rn")) {
$inheader = 0;
}
if ($inheader == 0) {
echo $line;
}
}
fclose($fp);
