我希望使用 fsockopen 在 http 请求中发送多个文件和发布变量。
已经想出了这段代码，但我不知道如何发送带有文件的帖子变量！？已取消注释构建发布数据查询的行，但不知道如何将其放入请求中！？:(
索引.php
$post_vars = [
'label' => 'description of the upload'
];
$files = [
'upload_file_1.txt',
'upload_file_2.txt'
];
try{
$boundary = sha1(1);
$crlf = "\r\n";
$body = '';
foreach($files as $file){
$finfo = new \finfo(FILEINFO_MIME);
$mimetype = $finfo->file($file);
$file_contents = quoted_printable_encode(file_get_contents($file));
$body .= '--'.$boundary.$crlf
.'Content-Disposition: form-data; name="files[]"; filename="'.basename($file).'"'.$crlf
.'Content-Type: '.$mimetype.$crlf
.'Content-Length: '.strlen($file_contents).$crlf
.'Content-Type: application/octet-stream'.$crlf.$crlf
.$file_contents.$crlf;
}
$body .= '--'.$boundary.'--';
//$post_data = http_build_query($post_vars);
$response = '';
if($fp = fsockopen('localhost', 80, $errno, $errstr, 20)){
$write = "POST /api_test/filepost/post.php HTTP/1.1\r\n"
."Host: localhost\r\n"
."Content-type: multipart/form-data; boundary=".$boundary."\r\n"
."Content-Length: ".strlen($body)."\r\n"
."Connection: Close\r\n\r\n"
.$body;
fwrite($fp, $write);
echo "-------------------- REQUEST START --------------------\n".$write."\n-------------------- REQUEST END --------------------\n\n\n";
while($line = fgets($fp)){
if($line !== false){
$response .= $line;
}
}
fclose($fp);
echo "-------------------- RESPONSE START --------------------\n".$response."\n-------------------- RESPONSE END --------------------\n\n";
}
else{
throw new Exception("$errstr ($errno)");
}
}
catch(Exception $e){
echo 'Error: '.$e->getMessage();
}
post.php
echo "get\n";
print_r($_GET);
echo "post\n";
print_r($_POST);
echo "files\n";
print_r($_FILES);
输出
