cURL Command Converter

The cURL Command Converter is a professional HTTP request code generation tool that converts cURL commands into HTTP client code for 30 mainstream programming languages with one click. Suitable for API development, testing, documentation writing, and similar scenarios, significantly improving cross-language development efficiency.

Key Features

Multi-Language Support

Supports conversion to code for the following 30 languages and frameworks:

General Languages

Python (requests / http.client)
JavaScript (native / Fetch / jQuery / XHR)
Java (HttpURLConnection / OkHttp / Jsoup)
Go, C, C#, Dart, Elixir, Julia, Kotlin, Lua, MATLAB, Objective-C, OCaml, Perl, PHP, R, Ruby, Rust, Swift, Clojure

Node.js Ecosystem

Native http module
Axios, Fetch, Got, Ky, Request, SuperAgent

PHP Frameworks

Guzzle, Requests, native cURL

Other Tools

HTTPie, Wget, PowerShell (RestMethod / WebRequest)
Ansible, CFML, HAR/JSON formats

Each language provides code style and best practices consistent with that language's conventions.

Intelligent Syntax Highlighting

Conversion results automatically apply syntax highlighting for the corresponding language, improving readability and review efficiency.

Complete Feature Preservation

All important information from cURL commands is preserved during conversion:

HTTP method (GET, POST, PUT, DELETE, etc.)
Request headers
Request body (Body / Form Data / JSON)
Query parameters
Authentication information (Basic Auth / Bearer Token)
Cookie data
Proxy settings
SSL certificate options

Ensures converted code functionality is completely consistent with original cURL command.

One-Click Copy

Conversion results provide copy button; click to copy code to clipboard for quick pasting. Supports full copy and segment copy.

Use Cases

API Documentation Writing

Export cURL commands from browser developer tools or Postman, quickly convert to multi-language example code to enrich API documentation. Helps users quickly get started with integration in different programming languages.

Interface Testing

When testing API interfaces, copy requests as cURL format from browser Network panel, then convert to script language code for easy writing of automated test cases.

Cross-Language Migration

When migrating from one language project to another, use the tool to quickly convert HTTP request code, reducing manual rewriting workload.

Learning Reference

Beginners can learn usage methods and code styles of HTTP client libraries in various languages by observing implementation of the same request in different languages.

Conversion Examples

Simple GET Request

Input cURL:

curl -X GET "https://api.example.com/users$2page=1&limit=10" \
  -H "Authorization: Bearer token123"

Convert to Python (requests):

import requests

url = "https://api.example.com/users"
params = {"page": "1", "limit": "10"}
headers = {"Authorization": "Bearer token123"}

response = requests.get(url, params=params, headers=headers)
print(response.json())

Convert to JavaScript (Fetch):

const url = "https://api.example.com/users$4page=1&limit=10";
const headers = {
  "Authorization": "Bearer token123"
};

fetch(url, { headers })
  .then(response => response.json())
  .then(data => console.log(data));

POST Request with JSON

Input cURL:

curl -X POST "https://api.example.com/users" \
  -H "Content-Type: application/json" \
  -d '{"name":"John","email":"[email protected]"}'

Convert to Java (OkHttp):

OkHttpClient client = new OkHttpClient();

MediaType JSON = MediaType.parse("application/json; charset=utf-8");
RequestBody body = RequestBody.create(JSON, "{\"name\":\"John\",\"email\":\"[email protected]\"}");

Request request = new Request.Builder()
    .url("https://api.example.com/users")
    .post(body)
    .addHeader("Content-Type", "application/json")
    .build();

Response response = client.newCall(request).execute();

Form Data Submission

Input cURL:

curl -X POST "https://api.example.com/upload" \
  -F "[email protected]" \
  -F "title=My Photo"

Convert to PHP (Guzzle):

<$6php
$client = new \GuzzleHttp\Client();

$response = $client->post('https://api.example.com/upload', [
    'multipart' => [
        [
            'name' => 'file',
            'contents' => fopen('photo.jpg', 'r')
        ],
        [
            'name' => 'title',
            'contents' => 'My Photo'
        ]
    ]
]);
