How build plugin with native go toolchain?

[aagumin]

I want call my go plugin with extism

extism call plugin.wasm afsync --input='{"once":false,"restore":false}' --wasi --log-level=debug -v --config s3bucket=abc

TinyGo not support net/http , i try

 GOOS=wasip1 GOARCH=wasm go build -o plugin.wasm main.go

output

extism call plugin.wasm afsync --input='{"once":false,"restore":false}' --wasi --log-level=debug -v --config s3bucket=abc

pdk.NewHTTPRequest you have to use + set allowed_hosts in config

I’m trying to use default transport

	http.DefaultTransport = &pdkhttp.HTTPTransport{}

it's doens't work

tinygo build -target wasi -o plugin.wasm -buildmode=c-shared main.go
../../../go/pkg/mod/github.com/aws/smithy-go@v1.24.0/transport/http/middleware_http_logging.go:6:2: package net/http/httputil is not in std 
make: *** [build] Error 1

And as I understand it, all such things should be added to the TinyGo package. tinygo-org/net#34
I would like to depend only on the regular toolchain.

this works for me @aagumin

example

func httpPdkFunc() int32 {
	apiKey, _ := pdk.GetConfig("api_key")
	req := pdk.NewHTTPRequest(pdk.MethodPost, "https://api.host.com")
	req.SetHeader("Authorization", "Bearer "+apiKey)
	req.SetHeader("Content-Type", "application/json")

	body := Body{}

	b, err := json.Marshal(body)
	if err != nil {
                pdk.SetError(err)
		return 1
	}

	req.SetBody(b)
	resp := req.Send()
	if resp.Status() != statusOk {
                pdk.SetError(fmt.Errorf("status is not ok: %d, %s", resp.Status(), resp.Body()))
		return 1
	}

	//resp.Body()
}

to compile:

GOOS="wasip1" GOARCH="wasm" go build -o plugin.wasm -buildmode=c-shared main.go

@Gasoid thank you! It's work!
