我需要使用PHP发送多部分/相关内容。内容将存在3个文件（2x XML，1XPDF）XML文件需要编码为7位PDF文件需要编码为base64
我可以构建这样的文件，但是我无法弄清楚如何用php中的卷发发送它。
内容应该是这样的（我剥离了大多数编码的PDF）。此exapmle来自另一个封闭式应用程序：

我尝试了以下内容，但它给出了一个空的结果：
$url="1.2.3.4";
$data = array('name' => basename($filePath), 'file' => '@' . realpath($filePath));
$data = array('file' => '@' . realpath($filePath));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 300);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-type: multipart/related'
));
$result = curl_exec($ch);
$info = curl_getinfo($ch);
// curl_close($ch);
if ($result === false || $info['http_code'] != 200) {
$output = "No cURL data returned for $url [" . $info['http_code'] . "]";
if (curl_error($ch))
$output .= "n" . curl_error($ch);
}
else {
// 'OK' status; format $output data if necessary here:
echo 'succes';
}
也许它是一种更好的方法来用卷发选择构建完整的内容？而不是在...
之前构建内容"手动"预先感谢！
每https://stackoverflow.com/a/a/25998544/1067003，libcurl没有内置的机制来将请求编码为倍增/相关（并且这个人是作者和主要开发人员卷发，所以他知道）意味着您必须自己编码身体。
我无法访问服务器进行测试，但是我认为它会像这样：
<?php
declare(strict_types = 1);
$files = array (
new MultipartRelatedFile ( 'foo.php' ),
new MultipartRelatedFile ( 'bar.php' ),
new MultipartRelatedFile ( 'baz.php' )
);
$body = generateMultipartRelatedBody ( $files, $boundary );
$ch = curl_init ();
curl_setopt_array ( $ch, array (
CURLOPT_HTTPHEADER => array (
'Content-Type: multipart/related; boundary="' . $boundary.'"'
),
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => $body,
CURLOPT_URL => 'http://127.0.0.1:9999'
) );
curl_exec ( $ch );
class MultipartRelatedFile {
public $path;
public $postname;
public $content_type;
function __construct(string $path) {
if (! is_readable ( $path )) {
throw new Exception ( 'file is not readable!' );
}
$this->path = $path;
$this->content_type = mime_content_type ( $path );
$this->postname = basename ( $path );
}
}
/**
* generate http body for a multipart/related POST request
*
* @param MultipartRelatedFile[] $files
* @param string|null $boundary
*/
function generateMultipartRelatedBody(array $files, string &$boundary = NULL): string {
if (null === $boundary) {
$boundary = bin2hex ( random_bytes ( 10 ) );
}
$n = "rn";
$body = '';
foreach ( $files as $file ) {
$body .= $boundary . $n;
$body .= 'Content-Disposition: attachment; filename=' . $file->postname . $n;
$body .= "Content-Type: " . $file->content_type . $n;
$body .= $n . file_get_contents ( $file->path ) . $n;
}
$body .= $boundary . '--';
return $body;
}
警告：缺乏确保它在NetCat服务器中看起来正确，这是未经测试的代码。我还想指出，这些规格没有提及任何Content-Length标头，并且意味着如果以其他方式提供文件名（例如在Content-Disposition中），并且不使用start标头，则Content-Id是可选的。无论如何，可以在这里找到规格：https：//www.rfc-editor.org/rfc/rfc2112
编辑：忘了在初始内容类型标头的边界周围添加引号（;
