In the Anq CMS template,urlizeFilter: Exploring the Possibility of Parsing FTP and Local File Paths

When building and managing a website with AnQi CMS, we often need to include various links in the content to guide visitors to get more information. The system provides powerful template functions, whereurlizeA filter is a very practical tool that can automatically identify URLs in text and convert them into clickable hyperlinks. However, forFTPaddresses or local file paths,urlizeCan the filter also intelligently recognize and convert as well? After understanding the related features, we find that, urlizeThe filter mainly targets URLs for HTTP/HTTPS protocols and email addresses, and currently does not support direct recognition and conversionFTPaddress or local file path.

urlizeThe core function of the filter: Born for web content

urlizeThe original intention of the filter design was to simplify the conversion work of standard web links (HTTP/HTTPS) and email addresses in web page content. When the content of your article contains suchhttp://www.example.com/www.example.com(It will automatically complete the protocol),example.comeven[email protected]when it encounters a string like this,urlizethe filter will smartly wrap it in<a>Make it clickable in the tag. This greatly improves the efficiency and user experience of content creation, avoiding the麻烦 of manually adding links. For example, the document mentions,www.florian-schlachter.de/test="test"Such complex URLs,urlizecan also correctly handle the parameters and special characters within them, converting them tohttp://www.florian-schlachter.de/test=%22test%22standard web links like these.

FTP and local file paths:urlizeareas not covered

However, when we try toFTPan address (such as)ftp://ftp.example.com/file.zip) or a local file path (for example, under the)C:\Users\Documents\report.pdfor under the/var/www/uploads/image.jpg) applicationurlizeWhen filtering, it does not automatically convert it to a clickable hyperlink as it does with web links. This is mainly becauseurlizeThe filter is designed to focus more on HTTP/HTTPS protocols and email protocols, and its internal identification mechanism does not coverFTPThe format of a protocol or local file system path. All examples provided in the document are also based on web standards for links and email addresses, without mentioning support forFTPlocal paths.

This difference in design is understandable. Web links are publicly accessible resources, andFTPThe link is also a network protocol, but usually requires support from client software, and involves different security and access mechanisms.As for local file paths, they are often private information internal to the server. Directly exposing them and converting them into clickable links for the front end is not only technically challenging (because browsers cannot directly access any local path of the user), but it also poses serious security risks.

How to handle the requirements for FTP and local file paths?

If you indeed need to provide in the content of AnQi CMSFTPTo access resources or indicate the location of local files, consider the following methods:

  • Manually add FTP links:ForFTPAddress, you can manually add the full in the content editorftp://Format link. AlthoughurlizeThe filter does not automatically recognize this type of link, but manually added HTML links are usually recognized by the browser and attempted to open.
  • Host local files on a web server:The most common practice is to upload the required "local files" to your web server or a dedicated file server, and then access them via standard HTTP/HTTPS links. This way,urlizeThe filter can perfectly handle these links. For example, if yourreport.pdffile is uploaded touploadsdirectory, and accessed byhttp://yourdomain.com/uploads/report.pdfthenurlizeit can be converted into a clickable link.
  • Provide download instructions or explanations:If the file is indeed local to the user, or not suitable for direct link access, the best way is to provide clear text instructions within the content, such as 'Please save the report as'}]C:\Users\Documents\Under "or "connect via FTP clientftp.example.comDownloadfile.zip.

In summary, the Anqi CMS'surlizeThe filter is a powerful tool for handling web links and email addresses, designed to provide a smooth link experience for web content. But when facingFTPWhen dealing with addresses and local file paths, due to protocol characteristics and security considerations, it cannot be automatically converted.For this type of requirement, we need to adopt alternative solutions such as manually creating links, web-hosting files, or providing clear operation instructions.
