`stream` response in proto failed to generate http client

[akoserwal]

What happened:

rpc Subject(TestRequest) returns (stream TestResponse) {
        option (google.api.http) = {
            get: "/v1/subjects"
        };
    };

Running kratos proto client api/helloworld/demo.proto

doesn't generate only _grpc.pb.go

_http.pb.go

What you expected to happen:

generate HTTP and grpc client

How to reproduce it (as minimally and precisely as possible):

Add stream response

Anything else we need to know?:

Environment:

• Kratos version (use kratos -v): kratos version v2.7.3
• Go version (use go version): go version go1.22.3
• OS (e.g: cat /etc/os-release): darwin/arm64
• Others:

http client is not supported yet. #1958 #2896

HTTP has not yet thought of a good abstraction to implement one-way and two-way stream

[akoserwal]

That's true. Is it possible to handle the stream case like: grpc-gatewat https://grpc-ecosystem.github.io/grpc-gateway/docs/mapping/httpbody_messages/ ?

I need some time to study it

Example project to showcase adding an HTTP handler for the gRPC stream endpoint: https://github.com/akoserwal/stream-ex-kratos/blob/main/internal/server/http.go#L40 @shenqidebaozi

@akoserwal Let me take a look
