What the data for this use case looks like
Data for this use case comes from the real estate registration information system, cadastral survey database, housing transaction online signing system, tax system, and electronic certificate repository. The update frequency is once per day. Documents processed daily include registration applications, ownership certificates, surveying and mapping results, tax payment vouchers, real estate ownership certificates, and real estate registers. Data fields include real estate unit number, right holder name, location address, area, right type, and more. The unit for area is square meters. Registration quantity is measured in parcels. The data structure uses real estate units as the core linking item to associate ownership, transaction, and tax information across multiple systems.
Constraints on HTTP Interfaces and External Systems
These characteristics impose clear constraints on HTTP interface integration with external systems. Multiple data sources require interfaces to support connections to multiple external systems, with independent identity verification parameters configured for each system. The daily update frequency requires interfaces to support scheduled batch data pulling, to avoid excessive data volume in a single request. The variety of documents and fields requires structured data returned by interfaces to cover all core business fields. Without full coverage, complete ledger summary cannot be completed. The potential for severe errors from failed calls requires interfaces to be configured with retry mechanisms and exception checks, to prevent ledger generation errors caused by a single failed call.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Carry the Bearer Token assigned by the system | Meet identity verification requirements when connecting to multiple systems, comply with access permission rules of external systems |
variables | Pass core business fields such as real estate unit number, right holder name, and location address | Match parameter matching requirements for ledger summary, ensure external systems return corresponding data |
responseData | Structured format containing register fields, certificate numbers, and surveying and mapping data | Adapt to field extraction logic for ledger generation, simplify report generation steps |
| Request timeout | 300 seconds | Cover overall time spent pulling data across multiple systems, avoid call failure due to network latency |
| Retry count | 2 times | Address temporary network exceptions during single interface calls, improve call success rate |
| Data pull batch | First 100 entries | Avoid excessive data volume in a single request, reduce load pressure on external systems |
Three Common Misconfigurations
- An interface call returns a
401 Unauthorizedstatus code. This occurs because theAuthorizationparameter is not configured correctly, no valid identity token is carried, or the token has expired. - The generated ledger lacks fields related to surveying and mapping results or tax payment vouchers. This occurs because the associated real estate unit number parameter is not passed in
variables, so external systems cannot match the corresponding business data. - Interface calls trigger timeouts. This occurs because a reasonable timeout period is not set, and a single request pulls cross-system data exceeding the threshold, exceeding the response time limit of external systems.
How to Verify Proper Configuration
- A test request is sent, and the returned
responseDatais checked to confirm it includes core business fields such as real estate unit number and right holder name. - FastGPT v4.17.0 interface call logs are reviewed to confirm the
Authorizationparameter is carried correctly and has not expired. - The daily update trigger workflow is simulated, to verify the interface pulls data according to the configured batch size and completes ledger summary.
- The connection to one external system is disconnected to simulate an exception scenario, and the system checks whether the preset retry mechanism is triggered.
