The path of the Banner image output by the `bannerList` tag is an absolute path or a relative path?

As an experienced website operations expert, I fully understand the importance of image path handling in a content management system for the overall performance of the website, search engine optimization (SEO), and daily maintenance. Today, we will focus on AnQiCMS (AnQiCMS) inbannerListDiscuss in depth whether the image path of the Banner output by the tag is an absolute path or a relative path.

Unveil AnQiCMSbannerListThe image path strategy of the tag

For the AnQi CMS,bannerListTags are designed in the template to facilitate the call and display of the website's carousel banner images. This is crucial for the visual appeal and information delivery of the website. When we are using{% bannerList banners %}Such a tag to loop output Banner pictures, for example, through{{item.Logo}}To get the picture address, the path it returns is usuallyThe relative path to the root directory of the websiteOr it may be in some specific casescomplete absolute paths.

Let's analyze what this means in detail.

1. Relative root path (starting with/at the beginning)

This is a common way for AnQiCMS to handle internal image uploads (including Banner images). After uploading a Banner image through the backend, the system will store the image in a specific directory on the server, such as/public/uploads/a subdirectory. At this point,bannerListLabel output{{item.Logo}}it will be a path starting with a slash/such as a path starting with/uploads/2023/banner_image.jpg.

The characteristics of this path are:

• not related to the website domain:No matter what your website domain iswww.example.comOrdev.example.com, the image path is always/uploads/images/banner.jpg. When the browser receives this path, it will automatically append it to the current website domain to form a complete URL, such ashttp://www.example.com/uploads/images/banner.jpg.
• High flexibility:This path is very conducive to website migration and multi-site management.Even if the domain name is changed or deployed on different subdomains, the image link remains valid and will not cause the image to fail to load due to path errors.
• SEO friendly:The search engine spider can easily parse these paths and associate them with the main domain of the website, which helps the images to be correctly indexed.

2. A complete absolute path starting withhttp://orhttps://at the beginning)

In some cases,bannerListThe label may also output the complete absolute path. This usually happens in the following two cases:

• Reference external images:If you enter an image URL from another website directly when setting the Banner in the AnQiCMS background (for examplehttps://external.com/banner.png), and AnQiCMS did not choose to download it locally, then{{item.Logo}}Output this external absolute path as is.
• System internal configuration:Even though it is not common, if AnQiCMS forces to add complete paths for all internal image paths in the underlying configurationBaseUrl(i.e., website address), it may also be a complete absolute path.However, according to the AnQiCMS documentation and common practice, it is preferred to output relative to the root path to maintain flexibility.

Why does AnQiCMS choose this path processing method?

This is the practical consideration in the design of the content management system:

• Unified resource management:AnQiCMS places the static resources of the website (such as images, CSS, JS) in one place:/public/static/or/uploads/Under the same directory, these directories are mapped to the root directory of the website via a web server (such as Nginx, Apache).This structure ensures that all image resources can be uniformly managed and accessed.
• To avoid dead links:Relative path to the current page level (for example../images/banner.jpgWhen the website structure changes (such as URL rewriting, page hierarchy adjustment), it is prone to failure, leading to the inability to display a large number of images. On the other hand, the relative root path can effectively avoid this problem.
• Performance and CDN Integration:Convenient for CDN (Content Delivery Network) integration with the relative root path. You just need to set in the CDN configuration that/uploads/Map the path to the CDN domain, no need to modify the image path inside AnQiCMS.

Impact on website operation and template design

UnderstandingbannerListThe way to handle image paths, for website operators and template designers, has the following practical significance:

• Template design is more efficient:Template designers can use them with confidence.{{item.Logo}}No need to worry about the path causing problems on different pages or in different environments.
• SEO optimization is more accurate:A clear and uniform image path structure helps search engines crawl and index, avoiding SEO problems caused by chaotic paths.
• Maintenance cost reduced:No matter how the website deployment environment changes, the stability of the image path greatly reduces the maintenance cost and the probability of errors.
• Cross-platform compatibility:Whether on the PC端 or mobile end, AnQiCMS can ensure that pictures are displayed normally through a unified path mechanism.

How to verify the image path?

If you want to verify it yourselfbannerListThe type of output image path, which can be done through the following simple steps:

1. Open your AnQiCMS website homepage or a page containing the Banner in the browser.
2. Right-click on the Banner image and select 'Inspect Element' or 'View Image Information' (options may vary depending on the browser).
3. View in Developer Tools<img>label'ssrcProperty value. You will see that the path starts with/starting from the relative root path) or withhttp://orhttps://starting from the full absolute path).

Some global settings of AnQiCMS (such asBaseUrlThis may also affect this behavior, but for content images, it is usually implemented by combining the relative root path with server-side rewriting or CDN configuration.

Q2: How does AnQiCMS ensure the stability of the URL address of the Banner image I uploaded, even if I replace the image?
