What Data in This Category Looks Like
The policy data for urban water services originates from official public documents released by the Ministry of Housing and Urban-Rural Development, local water authorities, and urban investment companies. National-level policies are published annually. Local policies are updated quarterly or via emergency patches. Individual policy documents consist primarily of normative text, including fields such as document number, issuing authority, effective date, applicable scenarios (e.g., water supply guarantee, pipeline network maintenance, sewage treatment), and clause content. Some fields related to fees or pipeline network length include corresponding units.
Constraints Imposed on HTTP Interfaces and External Systems
Water service policies vary by city. Interface requests must include a region identification parameter to accurately retrieve target content and avoid irrelevant data. Policy update cycles are irregular and include emergency patches. Interfaces must support incremental synchronization based on timestamps to reduce transmission overhead from full data pulls. Individual policy documents can be lengthy. Interface responses must limit the size of single data entries to prevent timeouts or knowledge base chunking failures. Policy content must match preset fields to be stored correctly. Interface returned fields must align with the knowledge base’s structured requirements.
Configuration Settings
These settings apply to FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Region filtering parameter | Pass the administrative division code of the target city | Adapt to regional differences in water service policies across cities and avoid retrieving irrelevant content |
Authorization | Pass the exclusive key bound to the knowledge base | Ensure the legitimacy of interface call permissions and prevent unauthorized access |
variables | Pass variables for policy applicable scenarios (e.g., water supply, pipeline network maintenance) | Accurately retrieve policy content for corresponding scenarios |
| Incremental synchronization timestamp | Use the last update time from the previous synchronization | Only pull newly added or modified policy documents to reduce interface transmission load |
| Single document return limit | 800–1200 characters | Match the conventional requirements of knowledge base chunk processing and avoid timeouts caused by overly long single data entries |
| Number of documents per request | First 5 entries | Control the volume of data returned by the interface and adapt to the recall limit settings of the knowledge base |
| Interface timeout period | 600 seconds | Adapt to the loading and transmission duration of large policy documents and avoid mid-process interruptions |
responseData | Extract fields including document number, effective date, and clause content | Only retain valid information required by the knowledge base and simplify subsequent processing |
Three Common Misconfigurations
- A 401 unauthorized error occurs when calling the interface. This is caused by failing to correctly configure the exclusive key, and using a public key which leads to permission verification failure.
- The interface returns an unreachable error when passing a local docx file via URL. This is caused by failing to configure public access permissions for external documents, or the URL path not pointing to a publicly accessible resource.
- The number of policy documents returned by the interface is insufficient. This is caused by failing to adjust the configuration for the number of documents per request, where the default recall count is too low to cover all required content.
How to Confirm Proper Configuration
- Call the interface with the preset target city administrative division code and the last synchronization timestamp. Check that returned results only include the latest policy documents for the target city.
- Check that the fields returned by the interface include preset fields such as document number, effective date, and clause content, with no missing or redundant fields.
- Call the interface multiple times and compare returned results. Confirm that incremental synchronization only pulls newly added or modified policy documents with no duplicate data.
- Check the interface timeout period configuration. Confirm it is set to approximately 600 seconds to adapt to the loading requirements of large policy documents.
