What error message will the `archive/list` interface return when the `moduleId` parameter is invalid?

When using AnQiCMS to build a website,archive/listThe interface is undoubtedly the core tool for obtaining content lists. Through this interface, we can flexibly filter and display various documents to meet the dynamic content needs of the website front-end. Among them,moduleIdThe parameter plays a very critical role, allowing us to specify the document under a specific content model (such as articles, products, news, etc.).

Under normal circumstances, when you are about toarchive/listAn effective interface inputmoduleIdThe interface will return the corresponding document list based on your request.For example, you may want to get all articles under the article model with ID 1, or product information under the product model with ID 2.However, during the actual development and content management process, we sometimes encountermoduleIdThe case where the parameter is invalid, which will directly affect the normal response of the interface.

WhenmoduleIdWhen the parameter is invalid,archive/listWhat error message will the interface return?

IfmoduleIdInvalid parameter, usually means you have provided a model ID that the AnQiCMS system cannot recognize.This might be because you passed a non-existent model ID, or the data type you passed does not match the expected interface (for example, the interface expects an integer, but you passed a string).

According to the AnQiCMS API interface design specification, when the request parameters are incorrect, the interface will return a general error code and continue tomsgThe field provides a specific error reason. Forarchive/listthe interface, whenmoduleIdan invalid parameter occurs, you will receive acodeWith-1response, andmsgthe field will clearly indicate the error details.

An example of a typical error response might look like this:

{
  "code": -1,
  "msg": "指定的模型不存在或 moduleId 无效。"
  // 或者类似 "Invalid Module ID" 等提示
}

In this response,code: -1it indicates that a general error has occurred whilemsgThe field prompt (for example, "The specified model does not exist or moduleId is invalid") clearly tells us where the problem lies: the system was unable to find the one you providedmoduleIdThe matching content model, or the one you providedmoduleIdThe value itself does not meet the legitimacy requirements of being a model identifier

Troubleshooting and solution思路 when encountering such an error

1. CheckmoduleIdvalidity:Firstly, the most important thing is to confirm that you are usingmoduleIdDoes it really exist in the AnQiCMS backend. Each content model has a unique numeric ID.You can log in to the AnQiCMS backend and view the IDs of all created models in the 'Content Model' or similar management interface.Ensure you did not manually enter a random or non-existent number.
2. CheckmoduleIdthe data type of: moduleIdExpected to be an integer (int). If you are calling the API through code, please make sure to check your code and ensure that you passmoduleIdThe value is indeed an integer type, not a string, boolean, or any other incompatible type. Even a string that looks like a number (such as"1"), may also be considered invalid in some programming languages or interface implementations.
3. Understand the optionality of parameters:It is worth noting that,archive/listinterface'smoduleIdThe parameter is marked as "No" (i.e., not required) in the document.This means that if you do not provide this parameter at all, the interface may try to return all available content models' documents or use some default display logic.But once you have clearly providedmoduleIdParameters, the system will strictly validate its value. If the provided value is judged to be invalid, even if the parameter itself is optional, the above error prompt will be triggered.

In summary, when you are callingarchive/listEncountered when using the interfacecode: -1When accompanied by prompts such as 'The specified model does not exist or moduleId is invalid', please prioritize checking the one you are usingmoduleIdWhether it accurately corresponds to the existing content model in the AnQiCMS backend and confirms that its data type meets the requirements of an integer.These detailed checks will help you quickly locate and solve problems, ensuring smooth calls to the content interface.

Frequently Asked Questions (FAQ)

Q1:moduleIdWhy is it an optional parameter, but if I provide an invalid value, it will cause an error?A1:moduleIdIt is an optional parameter, meaning that when you do not provide it, the system may have a default handling method (for example, returning the documentation of all models).When you choose to provide this parameter, AnQiCMS expects it to be a valid and existing model ID.If the provided value cannot be recognized or is invalid, the system will return an error. This is to ensure the accuracy and security of the data request, to avoid obtaining incorrect or unexpected data.

Q2: How can I find the correct one?moduleIdvalue?A2: There are two main methods:

*   **AnQiCMS 后台：** 登录您的 AnQiCMS 管理后台，找到“内容模型”或“模型管理”区域，通常每个内容模型都会明确显示其对应的 ID。
*   **API 调用：** 您可以调用 AnQiCMS 的 `module/list` 接口（获取模型列表接口），它会返回所有可用的内容模型及其对应的 ID，您可以从中选择合适的 `moduleId`。

Q3: BesidesmoduleId,archive/listWhat parameters of the interface should be noted to avoid similar errors?A3: BesidesmoduleId,categoryId(Document Category ID),idThe parameters such as (document ID) may also cause similar errors due to invalid values.code: -1For example, if you enter a non-existentcategoryIdOridThe value format is incorrect, the interface will also return an error and prompt the specific reason.Therefore, when calling any interface, you should carefully read the documentation to ensure that all parameters meet their expected data types, formats, and business logic.
