In website content management, the use of rich text editors greatly facilitates the creation and beautification of content.However, ensuring that the HTML content entered by users is both safe and correctly displayed on the front end while allowing them to freely format is a core challenge that every content management system must face.AnQiCMS as an enterprise-level content management system provides multi-level security mechanisms in this aspect.
When the user enters content in the rich text editor, AnQiCMS will perform a series of processes to ensure the accuracy and security of the content.The editor itself provides a rich set of formatting tools, allowing users to insert images, links, tables, and other elements.The system will perform preliminary cleaning and verification of the content it receives.For example, if the Markdown editor is enabled, the system will automatically convert Markdown formatted content to standard HTML, ensuring correct parsing and display on the front end.This approach avoids the potential format errors or malicious scripts that may be introduced by users directly manipulating HTML code.
When the content is stored and ready to be displayed on the website front end, the template engine of AnQiCMS plays a key role.The system uses a syntax similar to Django template engine, which defaults to escaping all output content as HTML.<script>alert('xss')</script>Such malicious scripts, the template engine will escape them by default.<script>alert('xss')</script>Thus, it is displayed on the page in plain text format rather than as executable script, effectively preventing cross-site scripting attacks (XSS).
However, the purpose of a rich text editor is to allow content to be displayed in rich HTML format. To achieve this, AnQiCMS providessafeFilter. When the content is trusted by the system and confirmed to be safe HTML code, it can be explicitly used in the template.{{ 变量 | safe }}This way to cancel the default HTML escaping, so that the browser will parse and render these contents as normal HTML structure. This allows for features like lazy loading of images (by means of the lazy="data-src"Properties) or embedded media, etc., can be displayed as expected.
For more complex display needs, such as mathematical formulas or flowcharts, AnQiCMS also provides good support.The system is built-in with a Markdown editor, allowing users to create content using specific Markdown syntax.To ensure that these complex elements can be rendered correctly on the front end, it is usually necessary to introduce third-party JavaScript libraries, such as MathJax for mathematical formulas, and Mermaid for flowcharts.AnQiCMS's openness and flexibility allow users to easily integrate these external resources into templates, thereby expanding their content display capabilities.In addition, the system also supports UTF-8 encoding, which is crucial for avoiding garbled content and ensuring the correct display of multi-language and special characters.
In summary, AnQiCMS offers multi-layered security protection (Go language底层, system built-in security mechanisms, default HTML escaping) and flexible content processing and front-end rendering mechanisms (rich text cleaning, Markdown conversion,safeFilter, integration with third-party libraries), ensuring the safety of HTML content in the rich text editor while maximizing the correct and beautiful display of content.This allows users to focus on content creation without having to worry too much about potential security risks and display compatibility issues.
Frequently Asked Questions (FAQ)
Why is the image or text style I added in the rich text editor displayed as plain text (i.e., showing HTML tags) on the front page?This is usually because you did not use
safeFilter. AnQiCMS template engine, for safety, defaults to escaping all HTML content, transforming<to<If you want the content to be parsed and rendered as an HTML tag by the browser, make sure to use the format in the template.{{ archive.Content | safe }}This format.How to ensure that external HTML code (such as embedded code from other websites) inserted into a rich text editor is safe and will not introduce malicious content?Although AnQiCMS provides multiple security mechanisms, but in using
safeWhen a filter directly renders external HTML code, users need to bear certain risks.It is recommended that you strictly review all HTML code from external sources to ensure that it is reliable and does not contain any malicious scripts.For content that is uncertain in terms of security, it can be considered to store through the custom fields of AnQiCMS, and then be rendered after the backend code performs more strict filtering or sandbox processing.Why did the Markdown formatted math formula or flowchart I inserted in the rich text editor not render correctly on the front end and only show the original Markdown syntax?AnQiCMS supports Markdown editing and can convert Markdown content to HTML, but complex rendering of mathematical formulas and flowcharts usually requires the use of specific front-end JavaScript libraries such as MathJax and Mermaid. You need to check the website template's
base.htmlOr related public files, confirm whether these library files have been correctly introduced according to AnQiCMS instructions. If not introduced, these advanced features will not display correctly on the front end.
