Installing Httpie

Installing Httpie is a simple process. The first step is to check if you have Python and pip, the package installer for Python, installed on your system. Most Linux distributions and macOS come with Python pre-installed, and you can check if it’s installed by running the command “python –version” in your terminal. If Python is not installed, you can download it from the official website.

Once you have Python and pip installed, you can use the following command to install Httpie:

pip install httpie

This command will download and install the latest version of Httpie and all its dependencies. After the installation is complete, you can start using Httpie by running the “http” command in your terminal.

If you’re using a Linux distribution that uses the apt package manager, you can also install Httpie by running the following command:

sudo apt install httpie

It’s also possible to install Httpie on Windows. You can find the instructions to do it on the official website.

Once you have Httpie installed, you can verify that it’s working by running the command “http –version” in your terminal, which should display the version number of Httpie that’s currently installed.

Making Basic HTTP Requests with Httpie

Httpie makes it easy to make HTTP requests and receive responses from the command line. The basic syntax for making a request is as follows:

http [method] [URL]

The method can be any of the standard HTTP methods such as GET, POST, PUT, DELETE, etc. The URL is the address of the resource you want to request.

For example, to make a GET request to the website “httpbin.org”, you can use the following command:

http GET httpbin.org

This will make a GET request to the root path of the website and display the response in the terminal.

To make a POST request, you can include a JSON or form data payload in the request by using the -j or -f option. For example, to make a POST request with a JSON payload, you can use the following command:





http POST httpbin.org/post -j '{"key": "value"}'

You can also include headers in the request by using the -H option. For example, to include an “Authorization” header in the request, you can use the following command:

http GET httpbin.org/headers -H "Authorization: Bearer YOUR_TOKEN"

You can also save the response to a file by using the -o option. For example, to save the response to a file named “response.txt”, you can use the following command:

http GET httpbin.org -o response.txt

Advanced Features of Httpie

Httpie offers a wide range of advanced features that allow you to customize and fine-tune your HTTP requests. Some of the key advanced features of Httpie include:

  • Customizable Output Formats: Httpie allows you to customize the output format of the response. You can use the –pretty option to control the formatting of the output, whether it’s plain text, JSON, or colored output.
  • Request Templates: Httpie allows you to create request templates that you can reuse and share. You can save a request as a template by using the –save-template option and then use the -T option to load the template and make the request.
  • Interactive Mode: Httpie has an interactive mode that allows you to explore an API by making requests and viewing the responses in real-time. You can enter interactive mode by using the -i option.
  • Authentication: Httpie supports various types of authentication, including basic, digest, and OAuth. You can include authentication information in the request by using the -A option.
  • File Uploads: Httpie allows you to easily upload files to a server by using the -f option. You can also include multiple files in the same request by using the -f option multiple times.
  • Timeout: Httpie allows you to set a timeout for the request by using the –timeout option. This is useful when you’re making requests to a server that might be slow to respond.
  • Redirection: Httpie supports redirections and allows you to follow redirects automatically by using the –follow option.

These are just a few examples of the advanced features of Httpie, and there are many more options and features that you can explore. With these advanced features, Httpie can be used for more complex tasks like testing web services, automating tasks and web scraping.

  • Interactive Mode: Httpie has an interactive mode that allows you to explore an API by making requests and viewing the responses in real-time. This is useful for testing APIs and checking the responses in real-time.
  • Automating API Tests: Httpie can be used in combination with scripting languages such as Python, Bash, or PowerShell to automate API tests. This can save time and increase efficiency when testing large numbers of API endpoints.

By using Httpie for API testing, developers can easily make requests, customize headers, handle data, and automate the process which can help to increase the quality of the product and reduce the time of testing.

Httpie Examples

  • Sending Requests with Various HTTP Methods:
http GET https://api.example.com/users
http POST https://api.example.com/users name=John
http PUT https://api.example.com/users/1 name=Jane
http DELETE https://api.example.com/users/1
  • Handling JSON and XML Data:
http POST https://api.example.com/users name=John -j
http POST https://api.example.com/users name=John -j '{"age": 25}'
  • Customizing Request Headers:
http GET https://api.example.com/users -H "Authorization: Bearer YOUR_TOKEN"
http POST https://api.example.com/users name=John -H "Content-Type: application/json"
  • Saving Responses to a File:
http GET https://api.example.com/users -o users.json
  • Request Templates:
http --save-template=users_template GET https://api.example.com/users
http -T users_template GET https://api.example.com/users/1
  • Interactive Mode:
http -i https://api.example.com
  • Automating API Tests: (Assuming the script is written in Python)
import httpie

response = httpie.get('https://api.example.com/users')
print(response.json())

response = httpie.post('https://api.example.com/users', json={'name': 'John'})
print(response.status_code)

Httpie vs cURL

Httpie and cURL are both command-line tools that allow you to make HTTP requests, but there are some key differences between the two:

  • Syntax: Httpie has a more intuitive and user-friendly syntax than cURL. The syntax is more similar to that of natural language and it’s easy to understand even for those who are not familiar with cURL. On the other hand, cURL has a more complex syntax, which can make it more difficult to use for some users.
  • Output Formatting: Httpie allows you to customize the output format of the response, whether it’s plain text, JSON, or colored output. cURL also supports customizing the output, but the options are less flexible and less user-friendly.
  • JSON and XML support: Httpie has built-in support for handling JSON and XML data, making it easy to send and receive data in these formats. cURL also allows sending and receiving JSON and XML data, but it requires additional libraries or flags.
  • Request Templates: Httpie allows you to create request templates that you can reuse and share. cURL does not have this feature.
  • Interactive Mode: Httpie has an interactive mode that allows you to explore an API by making requests and viewing the responses in real-time. cURL does not have this feature.
  • Automation: Httpie can be used in combination with scripting languages such as Python, Bash, or PowerShell to automate API tests. cURL also can be used in combination with scripting languages, but the process may be more complex.

Both tools have their own advantages, and the choice between the two often depends on the specific use case and personal preference. Httpie is more user-friendly, easier to use, and it’s more suitable for simple tasks, while cURL is more powerful and flexible, it’s more suitable for complex tasks and automation.
