Master the document list interface: the core of content filtering

To filter articles under specific categories, we need to make use of the Anqi CMS provided/api/archive/listThe interface. This interface is the core for obtaining the list of website documents, allowing you to precisely control the set of returned articles through various parameters.

The method of calling the interface isGETThis means you can pass filtering conditions through URL parameters. Where,categoryIdParameters are the key to implementing category-based article filtering.

UnderstandingcategoryIdParameter

categoryIdThe parameter allows you to specify one or more category IDs, and the interface will return articles belonging to these categories.

  • Single category filteringIf you only want to display articles under a specific category, you can directly pass the category ID. For example, if you want to get the ID of10articles under the category, the request parameters can includecategoryId=10.
  • multi-category filtering: If you want to display articles under multiple categories at the same time,categoryIdthe parameter also supports commas,Pass multiple category IDs in the form of separation. For example, to get the ID of10/12and15articles under the category, you can setcategoryId=10,12,15.

build your filter request

exceptcategoryIdIn practice, it is usually necessary to combine other parameters to construct a complete request to ensure that you get the content you really need.

  • moduleId(Model ID): Documents usually belong to a specific model (such as article model, product model, etc.). To filter more accurately, it is recommended that you also specifymoduleIdFor example,moduleId=1means to retrieve documents under the article model.
  • type(List type): When you need to get a paginated list and display the total count, it is usually thattypeis set topage. If you just want to list a specified number of documents,typeyou can omit or set it tolist.
  • child(Subcategory includes): A category may contain multiple subcategories. If you want to display not only the articles of the current category but also the articles of all its subcategories, you can setchildthe parameter totrue. By default, Anqi CMS usually includes subcategories, but it can be specified explicitlychild=falseYou can only get the articles directly under the current category, without including the content of its subcategories.
  • limitandpage(Pagination control): To control the number of articles displayed per page and to retrieve content for specific page numbers, you can uselimitandpagethe parameters. For example,limit=10&page=1to get the first 10 articles of the page.

a complete request examplemight look something like this:

{域名地址}/api/archive/list?moduleId=1&categoryId=10,12,15&type=page&limit=10&page=1&child=true

The meaning of this request is: to get the article modelmoduleId=1under, the category ID is10/12and15(including subcategories) articles displayed in a paginated manner, 10 per page, to get the content of the first page.

Parse the return result

After you send the request, AnQi CMS will return a JSON formatted response. A successful response will usually includecode: 0and adatafields, among whichdataA field is an array containing articles that meet the filtering criteria. Each article object will containid/title/description/category_idetc. information, you can display this information on the front end.
