解码 PHP 中的 curl 响应 gzip 多部分附件
decode curl response gzip multipart attachment in PHP
我正在尝试解码从 curl 请求收到的二进制压缩附件，附件是一个 xml 文件，但由 API 端点以二进制形式发送。这是我收到的完整请求：

我一直在搜索和尝试不同的东西但无法解码附件，我使用以下方法仅获取附件部分：
preg_match('/(?<xml><.*?\?xml version=.*>)/', $response, $match);
$xml = $match['xml'];
$offset = strpos($response, $xml) + strlen($xml . PHP_EOL);
$attach = substr($response, $offset);
我有一个工作的 C#.net 代码连接到相同的 API，如下所示：
byte[] myData;
byte[] rv;
using (var webResponse = req.GetResponse())
{
var responseHeaderstream = webResponse.Headers.ToByteArray();
var responseStream = webResponse.GetResponseStream();
myData = ReadFully(responseStream);
responseStream.Dispose();
rv = new byte[responseHeaderstream.Length + myData.Length];
System.Buffer.BlockCopy(responseHeaderstream, 0, rv, 0, responseHeaderstream.Length);
System.Buffer.BlockCopy(myData, 0, rv, responseHeaderstream.Length, myData.Length);
}
然后使用以下代码循环读取找到的任何附件，然后解压缩所有找到的附件，结果是一个 XML 文件，这种类型的请求应该只有一个附件：
Dim memstream As Stream = New MemoryStream(rv)
Dim entity As MimeMessage = MimeMessage.Load(memstream)
Dim attachments = New List(Of MimePart)()
Dim multiparts = New List(Of Multipart)()
Dim iter = New MimeIterator(entity)
While iter.MoveNext()
Dim multipart = TryCast(iter.Parent, Multipart)
Dim part = TryCast(iter.Current, MimePart)
If multipart IsNot Nothing AndAlso part IsNot Nothing AndAlso part.IsAttachment Then
multiparts.Add(multipart)
attachments.Add(part)
End If
End While
For i As Integer = 0 To attachments.Count - 1
multiparts(i).Remove(attachments(i))
Next
For Each attachment In attachments
Using memory = New MemoryStream()
attachment.Content.DecodeTo(memory)
Dim bytes = memory.ToArray()
If attachment.ContentType.MimeType = "application/gzip" Then
strAtchmnt = Unzip(bytes)
Else
strAtchmnt = Encoding.UTF8.GetString(bytes)
End If
End Using
Next
下面是解码附件所需的其他函数：
Public Shared Function Unzip(ByVal bytes As Byte()) As String
Using msi = New MemoryStream(bytes)
Using mso = New MemoryStream()
Using gs = New GZipStream(msi, CompressionMode.Decompress)
CopyTo(gs, mso)
End Using
Return Encoding.UTF8.GetString(mso.ToArray())
End Using
End Using
End Function
Public Shared Sub CopyTo(ByVal src As Stream, ByVal dest As Stream)
Dim bytes As Byte() = New Byte(4095) {}
Dim cnt As Integer
cnt = -1
While cnt <> 0
cnt = src.Read(bytes, 0, bytes.Length)
If cnt <> 0 Then dest.Write(bytes, 0, cnt)
End While
End Sub
非常感谢任何帮助。
这是完整的 curl 请求，$pulreq 是已签名的 xml 文档，此处无需包含：

如果我们假设 \r\n 的第一个实例之前的数据的第一部分是“部分分隔符”，并且我们假设每个部分的元数据由 \r\n 分隔，并且对于每个部分，元数据和实际数据由“\r\n\r\n”分隔（这似乎是这种情况，并且非常让人联想到 multipart/form-data 格式的样子！） , 然后提取这些部分就像
function sectionExtractor(string $raw):array{

$separatorEndPos=strpos($raw,$rn);
$separator=substr($raw,0, $separatorEndPos);
// remove separator
$raw = substr($raw, $separatorEndPos+strlen($rn));
$rawSections = explode($rn.$separator,$raw);
$parsedSections = array();
foreach($rawSections as $rawSection){
$metadataDataSeparator=$rn.$rn;
$metadataDataSeparatorPosition = strpos($rawSection, $metadataDataSeparator);
$metadata=substr($rawSection, 0, $metadataDataSeparatorPosition);
$metadata = explode($rn, $metadata);
$metadata = array_filter($metadata, 'strlen'); // probably a bug in separator exploding logic..
$data = substr($rawSection, $metadataDataSeparatorPosition + strlen($metadataDataSeparator));
$parsedSections[]=["metadata"=>$metadata, "data"=>$data];

原始 zip 数据在那里
$sections[1]["data"] ，一旦你有了它，你就可以使用 PECL zipArchive 之类的东西，比如
$zipRaw = $sections[1]["data"];
$tmpZipFileHandle = tmpfile();
$tmpZipFileLocation = stream_get_meta_data($tmpZipFileHandle)['uri'];
fwrite($tmpZipFileHandle, $zipRaw);
$zip = new ZipArchive;
$zip->open($tmpZipFileLocation);
$zip->extractTo('/my/destination/dir/');
然后压缩文件的内容应该被提取到/my/destination/dir/
看来解决方法很简单，之前没想到
提取解码后的附件后，我只需要：
$xml_string = gzdecode($decoded_attachment);
结果是预期的 XML 附件
