Convert cURL to Go

How cURL to Go works

The Go output uses http.NewRequestWithContext + client.Do — the standard pattern in Go services and CLI tools. JSON bodies are encoded via encoding/json into a bytes.Buffer, urlencoded bodies use net/url's url.Values{}, and multipart uploads use mime/multipart. The snippet always sets a context with timeout, defers Body.Close(), and reads the response with io.ReadAll. For high-throughput callers, the converter wraps the request in a reusable http.Client with a custom Transport.

Go code example

Realistic GET + POST with headers and a JSON body, written using net/http.

package main

import (
	"bytes"
	"context"
	"encoding/json"
	"fmt"
	"io"
	"net/http"
	"net/url"
	"time"
)

func main() {
	client := &http.Client{Timeout: 30 * time.Second}
	ctx := context.Background()

	// GET with headers and query params
	q := url.Values{}
	q.Set("page", "1")
	q.Set("limit", "50")
	req, _ := http.NewRequestWithContext(ctx, http.MethodGet,
		"https://api.example.com/users?"+q.Encode(), nil)
	req.Header.Set("Authorization", "Bearer YOUR_TOKEN")
	req.Header.Set("User-Agent", "MyApp/1.0")
	resp, err := client.Do(req)
	if err != nil { panic(err) }
	defer resp.Body.Close()
	body, _ := io.ReadAll(resp.Body)
	fmt.Println(resp.StatusCode, string(body))

	// POST with JSON body
	payload, _ := json.Marshal(map[string]string{
		"name":  "Ada Lovelace",
		"email": "[email protected]",
	})
	postReq, _ := http.NewRequestWithContext(ctx, http.MethodPost,
		"https://api.example.com/users", bytes.NewReader(payload))
	postReq.Header.Set("Authorization", "Bearer YOUR_TOKEN")
	postReq.Header.Set("Content-Type", "application/json")
	postResp, err := client.Do(postReq)
	if err != nil { panic(err) }
	defer postResp.Body.Close()
}
