[I] help request: 如何正确配置http+pb的请求方式 [apisix]
snowleopard331 opened a new issue, #11260:
URL: https://github.com/apache/apisix/issues/11260
### Description
我想使用http+pb的方式进行请求，但是打开grpc-transcode插件后，无论json/pb都可以请求到，但是返回的始终是json，我的需求是返回pb。请求头中的accept也设置过，但是都没用，以下是我的路由配置：

No. All PB. No JSON. Do you know how to config APISIX route? Send PB and receive PB. Thank you.

At present, I am using APISIX to proxy my upstreams, and the client uses JSON as the HTTP body. Currently, grpc-transcode is enabled, so the client's input and output are both in JSON format. Now the client wants to use protobuf as the input and output, but I don't know how to configure it. I have tried some solutions, but none have been successful; using HTTP+PB requests, the upstream can receive and process them, but APISIX always returns JSON to the client. What I want is a route configuration that can return protobuf. Thanks

@snowleopard331, can you prepare a github gist/repo with a self contained example to reproduce this issue? I will take a look at this when I am free.

`grpc-transcode` is for transcoding between regular HTTP requests and gRPC, so it is expected that the upstream response is returned in JSON.
It sounds like you are not looking for any transcoding but to have APISIX proxy for your request to gRPC upstream service, is that correct?

I meant to ask, does the upstream return JSON even when not using APISIX?

I'm not aware if APISIX can do this. @shreemaan-abhishek thoughts?
