What is Python Requests-Toolbelt?

Python Requests-Toolbelt is a Python library that provides various utilities, helpers, and tools to work with the requests library. It extends the functionality of the requests library and makes it easier to work with.

How I came across Python Requests-Toolbelt

I am a Python developer and I was working on a project that involved making HTTP requests to a REST API. I was using the requests library for this purpose, but I needed some additional functionality that was not available in the requests library. That's when I came across Python Requests-Toolbelt.

Features of Python Requests-Toolbelt

  • Multipart Encoded File Uploads: It provides a file upload feature that allows you to upload large files to the server in chunks, without loading the entire file into memory at once.
  • Stream Encoded File Downloads: It provides a feature to download large files from the server in chunks, without loading the entire file into memory at once.
  • SSL Certificate Verification: It provides a feature to verify SSL certificates, which is important for secure communication over HTTPS.
  • HTTP Range Requests: It allows you to send HTTP range requests to the server, which is useful when you want to download only a specific portion of a large file.
  • Custom Authentication: It provides a feature to implement custom authentication schemes that are not supported by the requests library.
  • Throttled Requests: It allows you to limit the rate at which requests are sent to the server, which is useful when you want to avoid overloading the server.

How to use Python Requests-Toolbelt

To use Python Requests-Toolbelt, you need to install it using pip:


pip install requests-toolbelt

Once installed, you can import it in your Python code and start using its features:


from requests_toolbelt.multipart.encoder import MultipartEncoder

# Create a multipart-encoded payload
fields = {'username': 'john', 'password': 'doe'}
files = {'file': ('test.txt', open('test.txt', 'rb'), 'text/plain')}
encoder = MultipartEncoder(fields=fields, files=files)

# Send the request using the requests library
response = requests.post(url, data=encoder, headers={'Content-Type': encoder.content_type})

You can find more examples and documentation on the official Python Requests-Toolbelt website.
