What data belongs to this category
This category’s data originates from permission-restricted internal policy documents and hierarchically controlled internal data files from state-owned enterprises, government agencies, and public service institutions. Data updates follow internal institutional revision processes, with no fixed schedule. Document structures include permission identification fields, main file content, update timestamps, and storage paths. Field units include character count, file size (MB), and standard timestamp format. Only authorized roles can access this data. External system calls must carry valid permission verification credentials to prevent unauthorized access to non-authorized content.
What constraints do these characteristics impose on HTTP interfaces and external systems
Permission identification fields require interface calls to carry valid permission verification credentials, to avoid unauthorized access to non-authorized files. Large variation in document size requires interfaces to support file upload and parsing for a wide range of file volumes. No fixed update cycle requires interfaces to not rely on locally cached permission rules, and to call verification logic in real time. Support for long file names and multiple file types (audio, documents, images) requires interfaces to support multi-format parameter passing and standard path return logic.
How to configure settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Carry a Bearer Token-formatted permission credential with a validity period of 1200 seconds | Matches internal permission verification rules to prevent unauthorized access |
variables | Pass the current caller’s department ID and role identifier | Used for permission scope filtering on the interface side to ensure data isolation |
responseData | Only return file content and paths that the current caller has permission to access | Strictly follows the business requirement of permission-isolated file access |
| Interface timeout period | 600 seconds | Accommodates time spent uploading and parsing large files, and aligns with FastGPT v4.17.0 interface rules |
| File upload size limit | 1000 MB | Covers the size range of most internal policy documents |
| Long file name handling | Automatically truncate to 255 characters | Compatible with operating system path length limits to avoid 400 errors |
Three Common Misconfigurations
- Cross-origin errors occur during calls, with CORS-related prompts or status code 403 displayed in the frontend console. Cause: External calling domain names are not granted cross-domain permissions in the interface configuration, or the
Authorizationparameter is not carried correctly. - A 400 error is returned when uploading a file with a long file name. Cause: Automatic truncation or encoding handling for long file names is not configured, exceeding system path length limits.
- No accessible URL path is returned after calling the interface to upload audio or image files. Cause: The system path parameter for file storage is not specified in
variables, causing the interface to fail to generate a standard return path.
How to Confirm Correct Configuration
- Before calling the interface, check that the
Authorizationparameter conforms to the current institution’s permission credential format, and confirm that the credential has not expired. - After uploading a test file, verify that the returned
responseDataonly includes file content and paths that the current caller has permission to access, with no unauthorized data. - Simulate uploading a file with a long name, confirm that the interface does not return a 400 error, and that the returned path conforms to the
/api/system/img/xxx.pngformat. - After calling the interface to retrieve data, check that the returned fields include permission identification and update timestamps, matching the preset configuration.
