Blob upload dosn't work

[Crafter6432]

Hello,

I tried to use the new MediaMessage but that only seems to work from server to client,
if the client uploads binary data the Apihandler always gets MediaMessage.bytes = null.

rpc version: 0.5.5

Hello,

Thank you for your return.

It's actually because you are not sending a MediaMessage, but a binary, or whatever else.

A MediaMessage has fields such as bytes, contentType, etc.

If you want handle your file, you must provide a structure.

class RequestMessage {
  MediaMessage myFile;
}

@ApiMethod(method: 'POST', path: 'file/{id}')
Future<ResourceMessage> storeFile(String id, RequestMessage request) async {
  if (request.myFile.bytes == null || request.myFile.bytes.isEmpty) {
    throw new BadRequestError("No data received");
  }

  // store your file, request.myFile.bytes

  return new ResourceMessage();
}

The curl command which you allow to do that is
curl -F myFile=@/path/to/my_file.txt http://localhost:8080/cloud/v1/file/abcdef

I think we could fix this issue easily, but I'm not sure it fit with the RPC process. However, it could throw a format error.
