Forward headers to grpc hook java

[TaridaGeorge]

I have an angular app which has an upload file feature. On the frontend side I'm using tus-js-client, the tusd server is v2.4.0 and the hook is grpc. From the frontend, I upload the file with the Authorization header but the tusd doesn't seem to pass them to the grpc server that I have written in Java. Is there an option that I should enable in order for the Authorization token to be passed to my java app?

Is there an option to enable more logging in tusd in order for me to see also the headers that are send from tus-js-client to it?
In my java app, I can see that on the grpc hook I have no headers.

Setup details
Please provide following details, if applicable to your situation:

• Operating System: Linux
• Used tusd version: v2.4.0
• Used tusd data storage: disk store
• Used tusd configuration: --hooks-grpc 192.168.1.201:7333 --hooks-grpc-retry 5 --hooks-enabled-events "pre-create,post-create,post-receive,post-terminate,post-finish,pre-finish"
  -upload-dir=/opt/tusd/uploads/
• Used tus client library: tus-js-client

const upload = new tus.Upload(file, {
  endpoint: "http://172.17.0.1:1080/files",
  retryDelays: [0, 3000, 5000],
  metadata: metadata,
  onError: (error) => {
	  reject(error);
  },
  headers: {
	  Authorization: `Bearer ${metadata['authToken']}`,
  },
  onShouldRetry: function (err: any, retryAttempt, options) {
	  // omited
	  return true;
  },
  onProgress: (bytesUploaded, bytesTotal) => {
	  const percentage = (bytesUploaded / bytesTotal) * 100;
	  progressCallback(percentage.toFixed(2));
  },
  onSuccess: () => {
	  resolve(upload);
  },
});
  
upload.start();

Headers from the incoming requests are not attached to HTTP/2 requests for gRPC. Such an option to forward HTTP headers is only available for HTTP hooks (see the flag).

However, the headers from the incoming requests are also provided in the payload provided via gRPC:

tusd/pkg/hooks/grpc/proto/hook.proto

Lines 98 to 99 in 15f05c0

	// Header contains all HTTP headers as present in the HTTP request.
	map <string, string> header = 4;

Indeed. I've created a PR to handle those shortcomings. Please see #1114
