Python Bleach Library: How to use bleach in Django for text cleaning

Python Bleach is a Python library to help users clean and filter text to prevent cross -site script (XSS) attacks.Use BLEACH in Django can effectively filter the text entered by the user in order to ensure the security and stability of the website.This article will introduce how to use bleach in Django to clean text. First, make sure that Bleach is installed in your Django project: pip install bleach Next, open the `settings.py` file in the Django project, and add Bleach to the list of installed applications: python INSTALLED_APPS = [ ... 'django_bleach', ... ] Then, import Bleach in the view of your Django application: python from django_bleach.models import BleachField Now, you can use the `bleachfield` to define the fields that need to be cleaned.For example, suppose we have a model called `Post`, one of which is a` Content` field. We will use the content published by BLEACH cleaning users: python from django.db import models class Post(models.Model): content = BleachField() ... At this time, when the user creates or edit a post, Bleach will automatically filter the text to ensure that there is no malicious script.After that, you can present a clean text in the template, as shown below: html {{ post.content }} You can also make more advanced customization with BLEACH.For example, you can specify the allowable HTML tags and attributes, or disable specific tags.This can be completed by passing the options in the parameters of the `Bleachfield`.For example, the following code will only be allowed to label `<p>` and `<strong>` and prohibit any label containing the `Onclick` attribute: python class Post(models.Model): content = BleachField(tags=['p', 'strong'], attributes={'*': ['class']}, strip=True) ... In the above examples, the `strip = true` parameter will delete not allowed labels, while` tags` and `Attributes` define the allowed tags and attributes. By using the Python Bleach library, text cleaning in Django will become simple and safe.Make sure you know the various options and configurations of BLEACH to customize according to your project needs.
