How to use the `msg` field for precise error checking when the document detail interface returns `code: -1`?

Secure CMS Document Details Interface Returncode: -1Troubleshooting Guide for the Time Error

When using AnQiCMS for website content management, we often use its provided API interface to retrieve or operate data. When calling the document detail interface (such as/api/archive/detailIf the returned result containscodeField is-1This usually means that the request did not succeed, and an error occurred during the server-side processing.In such a situation, many users may feel confused, not knowing where the problem really lies.Fortunately, AnQiCMS provided a very important clue when designing the API - that ismsgfield.

code: -1The appearance is not a general "server error" prompt. It is more like a signal, indicating that the specific problem details are hidden in the following.msgThis field is in error.msgThe field carries the error information returned by the backend system, which is usually human-readable and can greatly help us accurately locate the problem instead of guessing aimlessly.

msgField: The Key to Error Tracing

Imagine you are trying toidorfilenameto get the detailed content of a document, but the interface returned{"code": -1, "msg": "文档ID或URL别名缺失"}. At this point,msgThe field clearly points out the problem: your request is missing the requiredidorfilenameparameters. If the response is{"code": -1, "msg": "文档不存在"}Then you know that the requested document ID or alias does not have a corresponding record in the database.

This detailed error description will greatly improve the efficiency of troubleshooting.It refines a general "error" into specific "missing parameter", "resource not found", or "incorrect data format", etc., allowing us to directly check the root cause of the problem.

Commoncode: -1Scenario andmsgGuidance

In the various interfaces of Anqi CMS,code: -1is a general error code, andmsgThe content of the field will vary according to specific business logic and error types. The following are some of the situations you may encounter when using the document details interface (or similar interfaces) as well asmsgField may provide help:

1. Parameter error or missing:

   • msgMay display:“Document ID or URL alias missing”, “Incorrect parameter ID format”, “Missing required parameter: id”

Check if your API request includes all the necessary parameters (such asarchiveDetailthe interface requiresidorfilename), and the types of these parameters (such asidMust be an integer, format conforms to API document requirements.

2. The requested resource does not exist:

   • msgMay display:'Document does not exist', 'Category does not exist', 'Model does not exist'
   • Troubleshooting direction: This means the document, category, or model you are trying to access does not exist in the system. You need to verify that you have providedidorfilenamewhether it is correct, ensuring it points to actual existing content.

3. Data validation failed:This situation is more common when submitting data at the interface, such asarchivePublishIt may also occur in other interfaces, such as when invalid filtering conditions are provided during search)

   • msgMay display:The title cannot be empty, the category ID is invalid, the value of the custom field [XXX] does not meet the requirements
   • Troubleshooting direction: Check if the data you submitted meets the business rules or field definitions. For example, when publishing a document, the title is usually required, and the category ID must be a valid category existing in the system.

4. Business logic error:

   • msgMay display:You do not have access to this document, the document price is 0, no payment is required, the order has been cancelled
   • Troubleshooting direction: This error indicates that the request is legal, but it cannot be completed due to certain business rules (such as permission restrictions, status mismatches, etc.).You need to check the current user's permissions or request whether the object's status meets the operation conditions.

5. System internal exception:

   • msgMay display:Database query failed, internal system error, please try again later, unknown error, please contact the administrator
   • Troubleshooting direction: WhenmsgAn internal system error prompt may mean that the backend server encountered unexpected technical issues while processing the request.You can try to re-submit the request. If the problem persists, you may need to check the server logs of AnQiCMS for more detailed technical stack information, or directly contact the AnQiCMS technical support team for assistance.
