Master HTTP Requests with Python: Easy Introduction to Httpie 🚀

Today, I want to introduce you to an HTTP tool library that I frequently use in my daily development — httpie. As a Python developer, we often need to debug API interfaces and test HTTP requests. While GUI tools like Postman are powerful, sometimes it’s more convenient and quicker to send requests directly from the terminal. Httpie is an elegant command-line HTTP client that makes sending HTTP requests as natural as chatting with an old friend!

Learning Objectives

• Master the basic installation and usage of httpie
• Learn to send various HTTP requests (GET, POST, PUT, etc.)
• Familiarize yourself with setting request parameters and headers
• Be able to handle file uploads and JSON data

Prerequisites

• Basic command-line operations
• Fundamentals of the HTTP protocol
• Usage of the Python package management tool pip

Core Content

1. Installation and Configuration

First, install httpie using pip:

pip install httpie

Once installed, we can use the http command. Let’s try the simplest GET request:

http httpbin.org/get

2. Basic Usage

GET Request

Send a GET request with parameters:

http GET 'httpbin.org/get' name==Wang role==teacher

POST Request

Send JSON data:

http POST 'httpbin.org/post' name=Wang age=18 hobby:='["Programming", "Reading"]'

Tip: Use := to send JSON values; httpie will automatically handle the data types.

3. Advanced Techniques

Custom Request Headers

Send a request with custom headers:

http 'httpbin.org/headers' User-Agent:Python-Demo API-Key:123456

File Upload

Upload a file:

http -f POST 'httpbin.org/post' file@~/test.txt

Authentication Request

Send an authenticated request:

http -a username:password 'httpbin.org/basic-auth/username/password'

4. Practical Features

• Syntax highlighting: Automatically displays responses in beautiful colors.
• Formatted output: JSON responses are automatically formatted.
• File Download: Use the --download parameter.
• Session Management: Use --session to save authentication information.

Practical Case
Let’s look at a complete API testing process:

# 1. First, get the token
http POST 'api.example.com/login' username=demo password=123456

# 2. Use the token to access protected resources
http GET 'api.example.com/users' Authorization:'Bearer abc123'

# 3. Upload a file with additional parameters
http -f POST 'api.example.com/upload' file@./data.csv category=report

Exercises

1. Use httpie to send a POST request to httpbin.org/anything containing the following data:

   • name: Your Name
   • age: Your Age
   • skills: An array containing at least 3 skills

Challenge Task

Implement a simple weather query tool:

1. Register for a weather API account
2. Use httpie to write a script to query the weather in your city
3. Parse the returned JSON data and display it in a formatted way

Summary

Today we learned:

• Installation and basic usage of httpie
• Methods for sending various HTTP requests
• Handling request parameters and headers
• File uploads and authentication requests
• Useful debugging techniques
