pass http request uri to grpc server

[jinleileiking]

Please follow the general troubleshooting steps first:

• [x] Update your protoc to the latest version
• [x] Update your copy of grpc-gateway to the latest version from github. with git fetch https://github.com/grpc-ecosystem/grpc-gateway master && git reset --hard FETCH_HEAD
• [x] Delete the protoc-gen-grpc-gateway and protoc-gen-swagger binary from your PATH, and install locally built binaries.

Bug reports:

Fill in the following sections with explanations of what's gone wrong.

Steps you follow to reproduce the error:

1. curl http://xxxx.com/adfa/ccc?eeee=5

What did you expect to happen instead:

my request is http://xxxx.com/adfa/ccc?eeee=5 I should use the string http://xxx.com/adfa/ccc?eeee=5 to do some checks by interceptor. But I cannot get the uri, I only have the http headers host etc. I need get uri From now, there is no way.

Suggest pass these headers:

url : http://xxxx.com/adfa/ccc?eeee=5
uri_full : xxxx.com/adfa/ccc?eeee=5
uri: xxxx.com/adfa/ccc

Could you explain a bit more about the background of the request?

• You wouldn't have such headers if it were a plain HTTP server but not an interceptor in grpc-gateway. For what concrete use case do you need the full URI as a header?
  • Why is the HOST header insufficient for the use case?
  • Is the use case common enough to implement in the grpc-gateway runtime? Or is it better to implement your custom HTTP middleware?

[jinleileiking]

It is not so common.

There is no way to write a middleware in grpc-gateway middleware. so I need write in grpc-interceptor.

@jinleileiking Were you able to solve this? Have come across a similar use case where I need to access the complete REST URI from the gRPC middleware.

You can do it with normal HTTP middleware around the runtime.ServeMux.
