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?page=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?page=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):

<?php
$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'
        ]
    ]
]);

Important Notes

cURL Syntax Requirements

Input cURL commands must conform to standard syntax; common parameters:

  • -X or --request: Specify HTTP method
  • -H or --header: Add request header
  • -d or --data: Send data (POST)
  • -F or --form: Send form data
  • -u or --user: HTTP Basic Authentication
  • -b or --cookie: Send Cookie
  • -A or --user-agent: Set User-Agent

Unsupported parameters or non-standard syntax may cause conversion failure.

Sensitive Information Handling

Conversion process is completed server-side; do not input cURL commands containing real passwords, tokens, or other sensitive information. Use placeholders to replace sensitive data and manually fill them in after conversion.

File Path Handling

Local file paths in cURL commands (such as -F "file=@/path/to/file") will be converted to file reading operations in code; adjust paths according to actual project needs.

Dependency Library Installation

Some converted snippets may require installing common HTTP client dependencies for that language. Conversion results typically include the necessary import/require statements.

Comparison with Similar Tools

Compared to tools like curlconverter.com and Postman Code Generator, this tool's advantages:

  1. Supports 30 languages with more comprehensive coverage
  2. Intelligent syntax highlighting enhances code readability
  3. Chinese localized interface lowers usage threshold
  4. Provides common examples for quick testing
  5. Standardized code style conforms to best practices of each language

Suitable for developers and technical documentation writers who frequently need cross-language API call conversion.
