这篇文章主要介绍了php发送post请求的三种方法,分别使用curl、file_get_content、fsocket来实现post提交数据,需要的朋友可以参考下
方法一：
/**
* 发送post请求
* @param string $url 请求地址
* @param array $post_data post键值对数据
* @return string
*/
function send_post($url, $post_data) {
$postdata = http_build_query($post_data);
$options = array(
'http' => array(
'method' => 'POST',
'header' => 'Content-type:application/x-www-form-urlencoded',
'content' => $postdata,
'timeout' => 15 * 60 // 超时时间（单位:s）
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
return $result;
}
//使用方法
$post_data = array(
'username' => 'stclair2201',
'password' => 'handan'
);
send_post('//www.jb51.net', $post_data);
方法二：Socket版本
<?php
/**
* Socket版本
* 使用方法：
* $post_string = "app=socket&version=beta";
* request_by_socket('chajia8.com', '/restServer.php', $post_string);
*/
function request_by_socket($remote_server,$remote_path,$post_string,$port = 80,$timeout = 30) {
$socket = fsockopen($remote_server, $port, $errno, $errstr, $timeout);
if (!$socket) die("$errstr($errno)");
fwrite($socket, "POST $remote_path HTTP/1.0");
fwrite($socket, "User-Agent: Socket Example");
fwrite($socket, "HOST: $remote_server");
fwrite($socket, "Content-type: application/x-www-form-urlencoded");
fwrite($socket, "Content-length: " . （strlen($post_string) + 8） . "");
fwrite($socket, "Accept:*/*");
fwrite($socket, "");
fwrite($socket, "mypost=$post_string");
fwrite($socket, "");
$header = "";
while ($str = trim(fgets($socket, 4096))) {
$header .= $str;
}
$data = "";
while (!feof($socket)) {
$data .= fgets($socket, 4096);
}
return $data;
}
?>
方法三：Curl版本
<?php
/**
* Curl版本
* 使用方法：
* $post_string = "app=request&version=beta";
* request_by_curl('//www.jb51.net/restServer.php', $post_string);
*/
function request_by_curl($remote_server, $post_string) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $remote_server);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'mypost=' . $post_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "jb51.net's CURL Example beta");
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
?>
下面是其他网友的方法：
class Request{
public static function post($url, $post_data = '', $timeout = 5){//curl
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_POST, 1);
if($post_data != ''){
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
}
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_HEADER, false);
$file_contents = curl_exec($ch);
curl_close($ch);
return $file_contents;
}
public static function post2($url, $data){//file_get_content
$postdata = http_build_query(
$data
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents($url, false, $context);
return $result;
}
public static function post3($host,$path,$query,$others=''){//fsocket
$post="POST $path HTTP/1.1\r\nHost: $host\r\n";
$post.="Content-type: application/x-www-form-";
$post.="urlencoded\r\n${others}";
$post.="User-Agent: Mozilla 4.0\r\nContent-length: ";
$post.=strlen($query)."\r\nConnection: close\r\n\r\n$query";
$h=fsockopen($host,80);
fwrite($h,$post);
for($a=0,$r='';!$a;){
$b=fread($h,8192);
$r.=$b;
$a=(($b=='')?1:0);
}
fclose($h);
return $r;
}
}
大家可以根据需要选择适合自己的即可。 |
