What are Curl and Httpie?

Before we dive into the conversion process, let's briefly review what curl and httpie are and why they are useful.

Curl

Curl is a classic tool that has been around since 1997. It stands for "client URL" and it allows you to transfer data from or to a server using various protocols, such as HTTP, FTP, SMTP, etc. Curl is widely supported on different platforms and languages, and it has many options and features to customize your requests. You can use curl to test APIs, download files, upload data, and more.

Here is an example of a curl command that makes a GET request to the GitHub API and prints the response headers:

curl -i https://api.github.com/users/octocat

Httpie

Httpie is a newer tool that was created in 2012. It stands for “HTTPie: a CLI, cURL-like tool for humans”. Httpie is designed to be a user-friendly alternative to curl, with a simpler and more expressive syntax, colorful output, and smart defaults. Httpie supports HTTP/1.1, HTTP/2, and HTTPS, and it can automatically handle JSON, forms, and file uploads.

Here is an example of an httpie command that makes the same GET request as the curl command above, but with a more readable syntax and output:

http -v https://api.github.com/users/octocat

How to Switch Between Curl and Httpie with Apidog?

Now that you know what curl and httpie are and why you might want to switch between them, let me introduce you to a tool that can make your life easier: apidog.

Here is how to use apidog to switch between curl and httpie:

Step 1: Paste or type your curl or httpie command in the input box.

You can either paste an existing command that you copied from somewhere, or type a new command from scratch. Apidog will automatically detect the type of the command and show you the corresponding icon (curl or httpie) on the left side of the input box.

Step 2: Click on actual request

Apidog will convert your command to the other tool and show you the result in the output box.

If you want to test the converted command and see the response from the server, you can click on the run button or press Ctrl+R. Apidog will execute the command and show you the response in the lower panel. You can also switch between the raw and formatted views of the response by clicking on the toggle button or pressing Ctrl+F.

Tips and Tricks for Switching Between Curl and Httpie
