What This Category of Data Looks Like
Data for this category mainly comes from the real estate registration information system, cadastral survey database, housing transaction online signing system, tax system, and electronic certificate library. The update frequency is daily. Commonly processed documents include registration applications, ownership certificates, surveying and mapping results, tax payment vouchers, real estate ownership certificates, and real estate registers. Each single document includes fixed fields such as right holder name, real estate ownership certificate number, location address, and surveying and mapping area. Units include square meters, parcel count, and others. Data exists in a mixed form of structured fields and unstructured files.
What Constraints Do These Characteristics Impose on the HTTP Interfaces and External Systems Link
Multi-source data docking requires HTTP interfaces to support cross-system requests. Interfaces must be compatible with field formats and authentication rules of different systems. Daily updated data sources require interfaces to support incremental pulling and scheduled synchronization. This prevents full data pulls from using excessive resources. Processing mixed structured and unstructured documents requires interfaces to support both field parameter passing and file upload capabilities. The high-risk nature of ownership verification requires interfaces to include timeout retry, idempotency guarantee, and error log retention mechanisms. This reduces the risk of registration errors.
How to Configure the Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Fixed Bearer token or dynamically obtained access credential | Unified authentication format is required for docking with multiple external systems to avoid cross-system authentication conflicts |
variables | Pre-set business variables such as real estate location address and right holder ID number | Adapt to field verification requirements for different declaration materials and reduce repeated configuration |
responseData | Extract core fields such as verification results and correction prompts | Focus on core business data and reduce the processing complexity of interface return data |
| Timeout setting | 30-60 seconds | Match the response delay range of cross-department systems and avoid interrupting the review process due to single request timeout |
| Maximum file upload size | 1000 MB | Adapt to the transmission requirements of large-size files such as surveying and mapping results and electronic certificates |
| Retry times | 2 times | Balance interface stability and resource usage, and avoid registration conflicts caused by repeated submissions |
Three Common Misconfigurations
- Phenomenon: Unable to upload declaration material files when calling the conversation interface, returning a 400 status code. Cause: File upload support is not enabled in the interface configuration, and the request header is not correctly set to multipart/form-data format.
- Phenomenon: The verification result field returned by the interface is empty, and ownership status information cannot be extracted. Cause: The correct return field mapping is not specified through the
responseDataconfiguration, causing the business logic to fail to read core business data. - Phenomenon: Repeated submission of the same declaration material triggers a registration conflict. Cause: Interface idempotency verification is not configured, and a unique business identifier is not added to the request, leading to the risk of duplicate registration.
How to Confirm the Configuration Is Correct
- A simulated request is initiated, a single registration application file is uploaded, and the interface return is checked for a 200 status code and expected verification result fields.
- A scheduled synchronization task is configured, and the updated data volume pulled by the interface is verified to match the daily updated data volume of the external system.
- An abnormal request scenario is triggered, and the automatic retry logic after interface timeout is verified to take effect, along with full retention of error logs.
- Cross-system docking is tested, the interfaces of the tax system and real estate registration system are called, and the authentication parameter
Authorizationis confirmed to complete identity verification normally.
