Make a http request from wasi

[dshemin]

Hi!

I try to make a http request from WASM module running on wazero and got an error^

Netdev not set

I try to use netdev package but can't find any suitable examples. Can someone tell me is it possible or not?

My module:

package main

import (
	"encoding/json"
	"errors"
	"fmt"
	"net/http"
	"os"
	"time"

	"tinygo.org/x/drivers/netdev"
)

//go:generate easyjson main.go

//export call
func call() {
	netdev.UseNetdev(/* That i should pass here? */)
	resp, err := http.Get("https://swapi.dev/api/people/1")
	handleErr(err, "get")

	if resp.StatusCode != http.StatusOK {
		handleErr(errors.New("not 200"), "check status code")
	}
	defer resp.Body.Close()

	var p People
	err = json.NewDecoder(resp.Body).Decode(&p)
	handleErr(err, "decode")

	fmt.Printf("%#v", p)
}

func handleErr(err error, msg string) {
	if err != nil {
		fmt.Println(msg + ": " + err.Error())
		os.Exit(1)
	}
}

//easyjson:json
type People struct {
	Name      string    `json:"name"`
	Height    string    `json:"height"`
	Mass      string    `json:"mass"`
	HairColor string    `json:"hair_color"`
	SkinColor string    `json:"skin_color"`
	EyeColor  string    `json:"eye_color"`
	BirthYear string    `json:"birth_year"`
	Gender    string    `json:"gender"`
	Homeworld string    `json:"homeworld"`
	Films     []string  `json:"films"`
	Species   []string  `json:"species"`
	Vehicles  []string  `json:"vehicles"`
	Starships []string  `json:"starships"`
	Created   time.Time `json:"created"`
	Edited    time.Time `json:"edited"`
	URL       string    `json:"url"`
}

func main() {

}

This module I build with this command:

tinygo build -o module/http_client.wasm -target=wasip1 module/http_client/main.go

My tingo version is 0.33.0
