How to perform html decoding/encoding using Python django?

Estimated read time 2 min read

In Django, you can perform HTML encoding and decoding using the django.utils.html module. The escape function can be used for HTML encoding, and the unescape function can be used for HTML decoding. Here’s an example of how to use these functions in a Django view:

from django.http import HttpResponse
from django.utils.html import escape, unescape

def encode(request):
    text = "<script>alert('Hello World!');</script>"
    encoded_text = escape(text)
    return HttpResponse(encoded_text)

def decode(request):
    text = "<script>alert('Hello World!');</script>"
    decoded_text = unescape(text)
    return HttpResponse(decoded_text)

In the above code, the encode view takes a string text containing an HTML script tag, and uses the escape function to encode it into HTML-safe text. The encoded text is then returned as a response using the HttpResponse class.

Similarly, the decode view takes a string text containing HTML-encoded text, and uses the unescape function to decode it back into its original form. The decoded text is then returned as a response using the HttpResponse class.

Note that it’s important to HTML-encode any user-generated content that will be displayed on a webpage to prevent cross-site scripting (XSS) attacks.
