cURL to Code Converter Examples

The cURL to Code Converter transforms curl commands into equivalent code in your target language. Below are examples showing the same request converted to multiple languages.

Input curl Command

curl -X POST https://api.example.com/users \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer token123" \
  -d '{"name": "Alice", "email": "alice@example.com"}'

JavaScript — fetch (async/await)

const response = await fetch('https://api.example.com/users', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer token123'
  },
  body: JSON.stringify({
    name: 'Alice',
    email: 'alice@example.com'
  })
});

if (!response.ok) {
  throw new Error(`HTTP error: ${response.status}`);
}

const data = await response.json();
console.log(data);

JavaScript — axios

import axios from 'axios';

const response = await axios.post('https://api.example.com/users', {
  name: 'Alice',
  email: 'alice@example.com'
}, {
  headers: {
    'Authorization': 'Bearer token123'
  }
});

console.log(response.data);

Python — requests

import requests

response = requests.post(
    'https://api.example.com/users',
    headers={
        'Authorization': 'Bearer token123'
    },
    json={
        'name': 'Alice',
        'email': 'alice@example.com'
    }
)

response.raise_for_status()
data = response.json()
print(data)

PHP — cURL

$ch = curl_init('https://api.example.com/users');
curl_setopt_array($ch, [
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST           => true,
    CURLOPT_HTTPHEADER     => [
        'Content-Type: application/json',
        'Authorization: Bearer token123'
    ],
    CURLOPT_POSTFIELDS     => json_encode([
        'name'  => 'Alice',
        'email' => 'alice@example.com'
    ])
]);

$response = curl_exec($ch);
curl_close($ch);
$data = json_decode($response, true);

Go — net/http

package main

import (
    "bytes"
    "encoding/json"
    "net/http"
)

body, _ := json.Marshal(map[string]string{
    "name":  "Alice",
    "email": "alice@example.com",
})

req, _ := http.NewRequest("POST", "https://api.example.com/users", bytes.NewBuffer(body))
req.Header.Set("Content-Type", "application/json")
req.Header.Set("Authorization", "Bearer token123")

client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
    panic(err)
}
defer resp.Body.Close()

Ruby — Net::HTTP

require 'net/http'
require 'json'
require 'uri'

uri = URI('https://api.example.com/users')
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true

request = Net::HTTP::Post.new(uri.path)
request['Content-Type'] = 'application/json'
request['Authorization'] = 'Bearer token123'
request.body = { name: 'Alice', email: 'alice@example.com' }.to_json

response = http.request(request)
data = JSON.parse(response.body)

Java — HttpClient (Java 11+)

import java.net.http.*;
import java.net.URI;

var client = HttpClient.newHttpClient();
var body = """
    {"name": "Alice", "email": "alice@example.com"}
    """;

var request = HttpRequest.newBuilder()
    .uri(URI.create("https://api.example.com/users"))
    .POST(HttpRequest.BodyPublishers.ofString(body))
    .header("Content-Type", "application/json")
    .header("Authorization", "Bearer token123")
    .build();

var response = client.send(request, HttpResponse.BodyHandlers.ofString());
System.out.println(response.body());

File Upload curl → Python

Input:

curl -X POST https://api.example.com/upload \
  -F "file=@report.pdf" \
  -H "Authorization: Bearer token123"

Python output:

import requests

with open('report.pdf', 'rb') as f:
    response = requests.post(
        'https://api.example.com/upload',
        headers={'Authorization': 'Bearer token123'},
        files={'file': f}
    )

response.raise_for_status()
print(response.json())

Common Use Cases

• Converting API documentation curl examples into application code
• Translating curl commands from runbooks into production code
• Learning HTTP client syntax for a new programming language
• Quickly prototyping API integrations from curl examples
• Converting curl commands shared by teammates into your language

Paste any curl command and select your target language to get clean, idiomatic code with proper error handling ready to use in your application.
