Returning 302 redirect as response

[ubenzer]

Hi,

I am looking for a way to return 302 redirects to another URL as a response from grpc-gateway. In my research, I couldn't find a way to do it. In fact, I somewhat assume that it is not possible due to this.

It would be really nice to provide this functionality.

Please see this SO question of mine, that explains the same thing in detail.

I thought there was an issue around having exact control of the raw http response body but I'm not seeing it now. I agree this is a use case that should be straightforward.

@ubenzer, you may be able to do that by using https://godoc.org/github.com/grpc-ecosystem/grpc-gateway/runtime#WithOutgoingHeaderMatcher. The question whether this is a good practice or not remains. Perhaps @tmc can help to shed some light since I'm dubious right now.

@ubenzer what did you end up doing? WithOutgoingHeaderMatcher worked or you ended up using some other approach?

I ended up implementing our logic on the client side. In one request I get the URL for the image and in the second request, we get the image itself by using the response of the first request.

This was implemented before I learned that such a thing WithOutgoingHeaderMatcher existed. I don't know if that would've been worked for me or not.

I'll close this issue as this is not required for me anymore.
