AnQiCMS, with its efficient and customizable features, provides website operators with powerful content management capabilities. In daily content publishing and site maintenance, AnQiCMS, especially in URL structure optimization, performs excellently, such as through pseudo-static configuration and automatic generationurl_tokenImprove SEO performance.However, even such an intelligent system, in certain specific scenarios, we still need to manually intervene in the escaping of URL parameters to ensure the correctness, stability, and security of the link.

The URL management mechanism of AnQiCMS: intelligent default processing

It is worth mentioning that AnQiCMS has handled the URL encoding issue well in most cases. When we create articles, categories, or single pages in the background, the system automatically converts Chinese titles to pinyin and generates a uniqueurl_tokenas part of the URL. For example, the link to the article details page may contain{id}/{filename}, the link to the category list may contain{catid}/{catname}and other predefined variables.

These URL fragments generated by the AnQiCMS system or processed through its built-in mechanisms (such as pinyin conversion, character filtering) are usually not required to be manually handledurlencodeoririencodeThe system has already considered URL specifications when building these links, ensuring they can be correctly parsed by browsers and avoid potential character conflicts. In addition, in the template usingitem.Link/category.LinkWhen obtaining the links generated by the system via these tags, these links are also securely encoded. AnQiCMS providesurlizeandurlizetruncFilter, which can also automatically recognize and convert URLs to clickable links in text, and perform basic character processing during the conversion.

Why manual intervention is needed: Coding requirements in special scenarios

Although AnQiCMS provides convenient automatic processing, manual use is still required in the following special scenariosurlencodeoririencodeIt is particularly necessary to escape URL parameters:.

  1. When dynamically building query parameters (Query Parameters):This is the most common manual coding requirement when we need to construct URL query parameters based on user input or other dynamic content. For example, a search function, the user may input content containing spaces, Chinese characters, or special symbols (such as&/?/=Keywords after （. If these unencoded keywords are directly concatenated as?q=安企 CMS, the space will be parsed as%20,CMS, and the space after } may also cause problems, even&Symbols will cause parameter parsing errors. InarchiveListtags such as, ifqthe value of the parameter comes from external dynamic input, then this value must be encoded.

  2. When the custom link contains non-standard characters:Although the custom URL alias of AnQiCMS (such asfilename/catnameThe input in the background will perform pinyin conversion or character restriction (only allowing letters, numbers, and underscores), but sometimes operations personnel may need to directly concatenate path segments containing non-URL safe characters in the template for specific requirements, or obtain strings containing special characters as part of the URL from other unprocessed data sources.To avoid link breakage or parsing errors, manual coding is required.

  3. The URL must include data, and the data itself must contain URL-sensitive characters:For example, a parameter needs to pass another URL address as a value. This embedded URL may contain?/&The separator for query parameters, which may be misinterpreted in the outer URL, leading to a chaotic link structure. It is used forurlencodepreventing such issues.

  4. Security consideration: Prevent URL injection and XSS attacks:If the value of the URL parameter directly comes from user input and is not properly encoded, malicious users may construct a URL containing HTML or JavaScript code, thereby triggering cross-site scripting (XSS) attacks. Manually
