As an experienced website operation expert, I fully understand the importance of image path handling in content management systems for the overall performance of the website, search engine optimization (SEO), and daily maintenance. Today, let's focus on the AnQiCMS (AnQiCMS).bannerListThe path of the Banner image output by the label is an absolute path or a relative path, this topic is discussed in depth.

Unveiling AnQi CMSbannerListThe image path strategy of the label

For the Anqi CMS,bannerListLabels are designed in the template for convenient calling and displaying 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 is used to cyclically output banner images, for example, through{{item.Logo}}To get the image address, the returned path is usuallyA relative path to the root directory of the website，or in some specific cases, it may beThe complete absolute path.

Let's take a detailed look at what this means.

1. Relative root path (starting with/)

This is a common way for AnQiCMS to handle internal image uploads (including Banner images). After we upload a Banner image through the backend, the system will store the image in a specific directory on the server, for example,/public/uploads/The subdirectory. At this time,bannerListtag output{{item.Logo}}will be a path starting with a slash/such as/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 beneficial for website migration and multi-site management.Even if the domain name is changed or deployed under a different subdomain, the image link remains valid and will not cause the image to fail to load due to incorrect paths.
  • SEO-friendly:The search engine spider can easily parse these paths when crawling pages, associate them with the main domain of the website, which helps images to be correctly indexed.

2. Full absolute path (withhttp://orhttps://)

In some cases,bannerListLabels may also output the full absolute path. This usually happens in the following two cases:

  • Refer to external images:If you enter an image URL from another website (for examplehttps://external.com/banner.png），and AnQiCMS did not choose to download it locally,{{item.Logo}}output this external absolute path as it is.
  • system internal configuration:Even though it is not common, if AnQiCMS forcibly adds complete paths to all internal image paths in the underlying configuration,BaseUrl(i.e., the website address), the output may also be the complete absolute path.However, according to AnQiCMS's documentation and common practice, it is more倾向于 output the relative root path for internal images 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 unifies the static resources of the website (such as images, CSS, JS):/public/static/or/uploads/Under the directory, these directories are mapped to the root directory of the website through a web server (such as Nginx, Apache).This structure ensures that all image resources can be managed and accessed uniformly.
  • Avoid dead links:Relative path to the current page level (for example,../images/banner.jpgIn the event that the website structure changes (such as URL rewriting, page hierarchy adjustment), it is prone to failure, leading to a large number of images not displaying. On the other hand, using the relative root path can effectively avoid these issues.
  • Performance and CDN Integration:Convenient for integration with CDN (Content Delivery Network). You just need to set in the CDN configuration that/uploads/This path mapping is to the CDN domain, no need to modify the image path inside AnQiCMS.

The impact on website operation and template design

UnderstandingbannerListImage path processing methods, which is of practical significance for website operators and template designers:

  • More efficient template design:Template designers can use it with confidence:{{item.Logo}}And there is no need to worry about path issues on different pages or environments.
  • More accurate SEO optimization:A clear and unified image path structure is helpful for search engine crawling and indexing, avoiding SEO problems caused by chaotic paths.
  • Reduced maintenance costs:No matter how the website deployment environment changes, the stability of the image path greatly reduces maintenance costs and the probability of errors.
  • Cross-platform compatibility:Whether on the PC end or mobile end, AnQiCMS can ensure the normal display of images through a unified path mechanism.

How to verify the image path?

If you want to verify it personallybannerListThe output image path type, you can obtain it through the following simple steps:

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

Common Questions and Answers (FAQ)

Q1: How can I make all Banner images load through the CDN domain?

A1: AnQiCMS itself outputs the internal image path relative to the root path. To load via CDN, you usually do not need to modify the AnQiCMS template.{{item.Logo}}.You need to configure your CDN domain at the CDN service provider and set the origin site to your AnQiCMS website domain./uploads/(or the directory where AnQiCMS actually stores images) The request for the path is forwarded to the CDN domain, or the image domain is dynamically replaced through the global JS when loading resources in the front-end template. Some global settings of AnQiCMS (such asBaseUrl）It may also affect this behavior, but for content images, it is usually achieved 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?

A2: According to the AnQiCMS image resource management instructions, when you replace the image, the image URL addressremain unchanged.This means that the system will ensure the stability of each image's unique identifier through some mechanism (such as using an image ID or file name hash as part of the URL).The replacement operation only updates the actual image file behind the URL without changing the URL itself, which is very beneficial for the long-term stability and SEO of the website.
