php 利用fsockopen GET/POST 提交表单及上传文件

1.GET

get.php

<?php
$host = 'demo.fdipzone.com';
$port = 80;
$errno = '';
$errstr = '';
$timeout = 30;
$url = '/socket/getapi.php';

$param = array(
    'name' => 'fdipzone',
    'gender' => 'man'
);

$url = $url.'?'.http_build_query($param);

// create connect
$fp = fsockopen($host, $port, $errno, $errstr, $timeout);

if(!$fp){
    return false;
}

// send request
$out = "GET ${url} HTTP/1.1\r\n";
$out .= "Host: ${host}\r\n";
$out .= "Connection:close\r\n\r\n";

fputs($fp, $out);

// get response
$response = '';
while($row=fread($fp, 4096)){
    $response .= $row;
}

fclose($fp);

$pos = strpos($response, "\r\n\r\n");
$response = substr($response, $pos+4);

echo $response;
?>

getapi.php

<?php
$name = $_GET['name'];
$gender = $_GET['gender'];

echo 'name='.$name.'<br>';
echo 'gender='.$gender;
?>

2.POST

post.php

<?php
$host = 'demo.fdipzone.com';
$port = 80;
$errno = '';
$errstr = '';
$timeout = 30;
$url = '/socket/postapi.php';

$param = array(
    'name' => 'fdipzone',
    'gender' => 'man',
    'photo' => file_get_contents('photo.jpg')
);

$data = http_build_query($param);

// create connect
$fp = fsockopen($host, $port, $errno, $errstr, $timeout);

if(!$fp){
    return false;
}

// send request
$out = "POST ${url} HTTP/1.1\r\n";
$out .= "Host:${host}\r\n";
$out .= "Content-type:application/x-www-form-urlencoded\r\n";
$out .= "Content-length:".strlen($data)."\r\n";
$out .= "Connection:close\r\n\r\n";
$out .= "${data}";

fputs($fp, $out);

// get response
$response = '';
while($row=fread($fp, 4096)){
    $response .= $row;
}

fclose($fp);

$pos = strpos($response, "\r\n\r\n");
$response = substr($response, $pos+4);

echo $response;
?>

postapi.php

<?php
define('UPLOAD_PATH', dirname(__FILE__).'/upload');

$name = $_POST['name'];
$gender = $_POST['gender'];
$photo = $_POST['photo'];

$filename = time().'.jpg';
file_put_contents(UPLOAD_PATH.'/'.$filename, $photo, true);

echo 'name='.$name.'<br>';
echo 'gender='.$gender.'<br>';
echo '<img src="upload/'.$filename.'">';
?>

3.上传文件

file.php

<?php
$host = 'demo.fdipzone.com';
$port = 80;
$errno = '';
$errstr = '';
$timeout = 30;
$url = '/socket/fileapi.php';

$form_data = array(
    'name' => 'fdipzone',
    'gender' => 'man',
);

$file_data = array(
    array(
        'name' => 'photo',
        'filename' => 'photo.jpg',
        'path' =>'photo.jpg'
    )
);

// create connect
$fp = fsockopen($host, $port, $errno, $errstr, $timeout);

if(!$fp){
    return false;
}

// send request
srand((double)microtime()*1000000);
$boundary = "---------------------------".substr(md5(rand(0,32000)),0,10);

$data = "--$boundary\r\n";

// form data
foreach($form_data as $key=>$val){
    $data .= "Content-Disposition: form-data; name=\"".$key."\"\r\n";
    $data .= "Content-type:text/plain\r\n\r\n";
    $data .= rawurlencode($val)."\r\n";
    $data .= "--$boundary\r\n";
}

// file data
foreach($file_data as $file){
    $data .= "Content-Disposition: form-data; name=\"".$file['name']."\"; filename=\"".$file['filename']."\"\r\n";
    $data .= "Content-Type: ".mime_content_type($file['path'])."\r\n\r\n";
    $data .= implode("",file($file['path']))."\r\n";
    $data .= "--$boundary\r\n";
}

$data .="--\r\n\r\n";

$out = "POST ${url} HTTP/1.1\r\n";
$out .= "Host:${host}\r\n";
$out .= "Content-type:multipart/form-data; boundary=$boundary\r\n"; // multipart/form-data
$out .= "Content-length:".strlen($data)."\r\n";
$out .= "Connection:close\r\n\r\n";
$out .= "${data}";

fputs($fp, $out);

// get response
$response = '';
while($row=fread($fp, 4096)){
    $response .= $row;
}

fclose($fp);

$pos = strpos($response, "\r\n\r\n");
$response = substr($response, $pos+4);

echo $response;
?>

fileapi.php

<?php
define('UPLOAD_PATH', dirname(__FILE__).'/upload');

$name = $_POST['name'];
$gender = $_POST['gender'];

$filename = time().'.jpg';

echo 'name='.$name.'<br>';
echo 'gender='.$gender.'<br>';
if(move_uploaded_file($_FILES['photo']['tmp_name'], UPLOAD_PATH.'/'.$filename)){
    echo '<img src="upload/'.$filename.'">';
}
?>
