What This Category of Data Looks Like
Data for this category originates from real estate registration information systems, cadastral survey databases, housing transaction online signing systems, tax systems, and electronic certificate repositories. Data is updated daily. Daily processed documents include registration applications, ownership certificates, surveying and mapping results, tax payment vouchers, real property right certificates, and real estate registers. Data fields include real estate unit numbers, right holder information, location addresses, right types, restriction statuses, and other relevant fields. Most units use standard address codes and square meters for area measurements. No custom non-standard units are used.
Constraints Imposed on HTTP Interfaces and External Systems
Multi-source data docking requires interfaces to support simultaneous connections to multiple heterogeneous external systems. Interfaces must be compatible with different systems' request formats and response structures. Daily updated data sources require interfaces to use incremental synchronization logic. This avoids excessive resource usage from full data pulls. Ownership verification requires calling data from multiple systems, so interface request frequency and timeout settings must align with business time requirements. Failed data validation can lead to registration errors or property right disputes. Interfaces must include strict parameter validation and failure retry mechanisms to ensure incoming data complies with business rules.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| External system connection timeout | 10–30 seconds | Adapts to average response latency of multiple heterogeneous external systems |
Authorization | Carry the API key assigned by the external system | Meets identity verification requirements for external interfaces |
| Variable mapping rules | Map the responseData field to the question-and-answer context variables | Ensures ownership data returned by external systems is correctly passed to the question-and-answer workflow |
| Knowledge base association configuration | Bind the dedicated real estate registration policy knowledge base | Matches the required policy and regulatory basis source for the business |
| Interface retry count | 2 times | Avoids call failures caused by temporary network fluctuations |
| Data synchronization scope | Only synchronize ownership data updated on the current day | Complies with the daily update frequency of the data source |
Three Common Configuration Mistakes
- An external interface call returns a 514 status code, indicating insufficient permissions. The cause is that the
Authorizationheader is not correctly configured, and a valid external system API key is not included. - The question-and-answer flow cannot associate the target policy knowledge base, returning empty policy basis results. The cause is that the dedicated real estate registration policy knowledge base is not bound in the application configuration.
- The interface returns empty data fields, preventing ownership verification. The cause is that correct variable mapping rules are not configured, so valid fields from
responseDataare not passed to the question-and-answer context.
How to Verify Proper Configuration
- Call the configured external interface and check if the returned
responseDatafield contains expected ownership data. - Review the knowledge base association settings in the application configuration to confirm the dedicated real estate registration policy knowledge base is bound.
- Launch a test question-and-answer query and verify that the returned results include matching policy and regulatory basis content.
- Simulate an interface call failure scenario to confirm the system triggers the preset retry mechanism.
