file upload and download in gRPC-Gateway

grpc-gateway-file's Issues

Problem with downloading big files.

If you run the example from the repository and try to download a file of more than 2 MB, then we get an error in the console and a broken file.
Use ServeFile() method

ERROR: Failed to send delimiter chunk: http: wrote more than the declared Content-Length

WithHTTPBodyMarshaler & UnmarshalOptions

Hi! In WithHTTPBodyMarshaler you're using DiscardUnknown=true. This causes grpc_gateway to stop checking the enums. Is there any need for this option?

Help wanted: "stream terminated by RST_STREAM with error code: PROTOCOL_ERROR"

If deploy example into kubernetes with linkerd, we got "stream terminated by RST_STREAM with error code: PROTOCOL_ERROR" error if we try to download file.

Maybe you know how to fix it?

The audio files are getting distorted afterd download, resulting in different md5sum

When I attempt to download an MP3 audio file, it becomes corrupted, exhibiting distortion noises. Upon checking the md5 checksums of the files, I found them to be different.

Problem with processing two or more files

Hello. When processing two or more files I get an error: "parse multipart form failed multipart: NextPart: EOF". Could you please tell me if it is possible to process two or more files? In your MultipartFormHeader method I am not sure about the logic and the possibility of working with multiple files. This library is convenient, but if there is a possibility, please clarify this point. Thank you.

func MultipartFormHeader(server UploadServer, key string) (*multipart.FileHeader, error) {

   form, err := ParseMultipartForm(server)
   if err != nil {
   	return nil, errors.Wrapf(err, "parse multipart form failed")
   }
   if headers := form.File[key]; len(headers) > 0 {
   	return headers[0], nil
   }
   return nil, http.ErrMissingFile

}
