swagger error

[vtolstov]

i have proto that contains:

service VolumesService {                                                                            
  rpc VolumesImport(stream Chunk) returns (VolumesImportRsp) {                                      
    option (grpc.gateway.protoc_gen_swagger.options.openapiv2_operation) = {                        
      operation_id: "VolumesImport";                                                                
    };                                                                                              
    option (google.api.http) = { put: "/api/v2/volumes/{volume_id}"; body:"*"; };      
  }                                                                                                 
}

when i'm try generate swagger, it oututs:
--swagger_out: cannot use path parameter in client streaming

as i understand in case of stream from client, i can't use path like "/api/v2/volumes/{volume_id}".
How to deal with this? I have method that via post create new volume and returns it uuid, after that i can put to it data via stream.

The gRPC gateway does not support client side streaming at this time. If you want to upload a file you will have to use multi-part uploads on a separate handler.

Closing as this has been covered in other issues. Please let me know if there's anything else you would like to ask.

but why i can't generate swagger? i don't want to use grpc-gateway, i'm use only swagger generator from proto files.

The provided gateway doesn't support it, that's why you can't generate swagger for it. if you would like to extend the swagger generator to support this, I would be happy to merge your pull request.
