问题描述
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
I need to send multipart/related content with PHP.The content will exist of 3 files (2x XML, 1xPDF)The XML-files need to be encoded as 7bitThe PDF-file needs to be encoded as base64
我可以建立一个像这样的文件,但是后来我不知道如何在PHP中使用curl来发送它.
I can build a file like this,but then i cant figure out how to send it with curl in PHP.
内容应该是这样的(我去除了大部分编码的pdf).该示例来自另一个封闭源应用程序:
The content should be something like this (i stripped out most of the encoded pdf). This exapmle comes from another closed-source application:

Content-Type: multipart/related;

我尝试了以下操作,但结果为空:
I tried the following, but it gives a empty result:
$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';
}
也许用curl-options来构建完整内容的更好的方法是谁?而不是在之前构建内容手动" ...
Maybe it whould be a better approach to build the complete content with curl-options? Instead of building the content 'manualy' before...
提前谢谢!
推荐答案
每 https://stackoverflow.com/a/25998544/1067003 ,libcurl没有内置机制将请求编码为多部分/相关(而且这是curl的作者和主要开发者,所以他知道),这意味着您必须自己编码主体.
per https://stackoverflow.com/a/25998544/1067003 , libcurl has no built-in mechanism to encode requests as multipart/related (and this guy is the author and main developer of curl, so he'd know) meaning that you have to encode the body yourself.
我无权访问服务器以进行测试,但是我认为它会像这样:
i don't have access to a server to test on, but i think it would go something like this:
<?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 = "\r\n";
$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:由于无法确保它在netcat服务器中看起来像是正确的,因此这是未经测试的代码.我还想指出,规范没有提及任何Content-Length
标头,并暗示了Content-Id
是可选的,如果文件名是以其他方式提供的(例如Content-Disposition
)并且start
标头未使用.无论如何,都可以在这里找到规格: https://tools.ietf.org/html/rfc2112
warning: short of making sure it looks correct-ish in a netcat server, this is untested code.i'd also like to point out that the specs doesn't mention any Content-Length
header, and implies that Content-Id
is optional if the filename is provided in some other way (like in Content-Disposition
) AND the start
header is not used.in any case, specs can be found here: https://tools.ietf.org/html/rfc2112
忘记在固定的初始Content-Type标头的边界周围添加引号().
edit: forgot to add quotes (") around the boundary of the initial Content-Type header, fixed.
