无法读取HTTP Foundation Symfony 3.3中的“文件”

Question

Recently I updated a symfony project from 3.2 to 3.3. I have an issue with a simple POST with a file. The file is not in the filebag of the http foundation object Request.

public function sendAction(Request $request){
    dump($request->files);
    dump($request->request);
    dump($request->headers);
    if (!$request->files->has("image")) {
        throw new HttpException(Response::HTTP_BAD_REQUEST, 'no "image" field');
    }
}

When I have a look at what it dumped, depending on the content-type of the request, I have different results :

If I use application/x-www-form-urlencoded as header, I have these dump : https://pastebin.com/5HSCAgut (sorry for pastebin links, output is too long)

If i use multipart/form-data as header, I have these dumps : https://pastebin.com/tZdVKNgG

What's wrong with my script ? Am i missing a new feature or security check ?

Ok it was a stupid client error. I specified the header :

Content-type: multipart/form-data

but it should be

Content-type: multipart/form-data; boundary=-------------BOUNDARYUSEDINREQUEST--------------
