Suggestion: add trpc as an extenions of api-testing

[LinuxSuRen]

hi the trpc team, I'm the maintainer of api-testing which aims to be an alternative solution to Postman. Instead of Postman, api-testing is totally open-source. And it has an extension (or plug-in) mechanism.

Add more background of api-testing. It already supports HTTP and gRPC protocols. For Docker users, you could simply type the following command to get started:

docker run --network host linuxsuren/api-testing:master

The web server local address is http://localhost:8080.

Hi, LinuxSuRen, I am glad to hear that. Contribution to tRPC ecosystem is highly welcome. Here is tRPC protocol ，Perhaps u can implement tRPC protocol and add it as the extenions of api-testing. Any question, U can leave a message here, we are glad to answer it asap.

[LinuxSuRen]

hi @sandyskies , thanks for the quick response.

[LinuxSuRen]

Below is the implement of gRPC

https://github.com/LinuxSuRen/api-testing/blob/06616860bf94d4a2034ec64551eb2a6f49db7a43/pkg/runner/grpc.go#L71

[sandyskies]

@LinuxSuRen can u implement tRPC protocol?

[LinuxSuRen]

I'm not familiar with the tRPC, especially about how to send the request dynamically. So this will not be a short task for me.

@LinuxSuRen So the advantages of API Testing are supporting multiple protocols such as gRPC or other RPC?

[LinuxSuRen]

I hope API Testing could support all popular API protocols. But it supports HTTP, gRPC for now.

It defined interface, and has two implements:

• interface https://github.com/LinuxSuRen/api-testing/blob/d5654394d22485dee4e4a31cc3314d4a6f3afea9/pkg/runner/runner.go#L13
• HTTP runner implement
• gRPC runner implement

[LinuxSuRen]

Anyone could help me to find an example about how to invoke a service method dynamically? Currently, I fond the code to parse the proto file. But I don't know how to form the req and resp for the Invoke method. Thanks for your time.

You may check this quick start. Checkout the implementation inside cmd/client/main.go

[WineChord]

Or are you seeking some tool that can take a proto file and some arguments as input to invoke a running service?

[LinuxSuRen]

hi @WineChord , thanks for your reply. I find the parse method from that project. I'm trying to Unmarshal a data by the following code:

	ser := restful.GetSerializer("application/json")

	send := []byte{}
	err = ser.Unmarshal([]byte(`{"name":"SuRen"}`), &send)
	fmt.Println(err)

	resp := []byte{}

	err = c.Invoke(ctx, send, resp, callopts...)
	fmt.Println(err)

but no process got for now.

Take a look at this function generated in stub code: https://github.com/trpc-group/trpc-go/blob/main/testdata/trpc/helloworld/helloworld.trpc.go#L109
