It emphasizes readability and usability, making it a great choice for testing APIs from the command line. HTTPie supports JSON by default, making it particularly convenient for modern web applications. • 2️⃣ Postman • Postman is a comprehensive tool for API testing, development, and documentation. It offers a GUI that makes it easy to construct requests, organize them into collections, and share them with others. Postman supports automated testing and offers extensive options for exploring APIs. • 3️⃣ Insomnia • Insomnia is another GUI-based HTTP client designed for API development and testing. It offers a clean interface with features like environment variables, response history, and request chaining. Insomnia is well-suited for developers working on RESTful, GraphQL, and WebSocket services. • 4️⃣ Wget • Wget is a command-line utility primarily used for downloading files from the web but can also send POST requests using the --post-data or --post-file options. It’s less feature-rich for API testing but is a robust tool for simple POST requests and downloading tasks. • 5️⃣ PowerShell (Invoke-WebRequest) • For Windows users, PowerShell’s Invoke-WebRequest cmdlet is a powerful alternative, offering extensive functionality for making web requests, including POST requests. It’s especially useful in scripting and automation within Windows environments. • 6️⃣ Fetch API/Axios (in JavaScript) • For developers working with JavaScript, especially in web development or Node.js environments, the Fetch API (for browser-based JavaScript) and Axios (a standalone HTTP client for both browser and Node.js) offer powerful and flexible ways to make HTTP requests, including POST requests. • ❓ Are cURL flags or command line options (arguments) case-sensitive? • Yes, cURL flags and command line options (arguments) are case-sensitive. This means that using uppercase or lowercase letters can affect how cURL interprets and processes the command. It's essential to ensure proper casing when specifying options to avoid errors or unexpected behavior in your cURL commands.
