Business Process Guidance for Land Pre-examination and Planning Permit: HTTP Interfaces and External Systems

What the Data for This Category Includes

Data related to land pre-examination and planning permit business originates from the national land and space planning unified map, project approval and supervision platform, current land use database, and ecological protection red line data. The update frequency is irregular. Daily business documents include land pre-examination and site selection opinion, construction land planning permit, construction project planning permit, red line drawing, and planning conditions. Document structures cover fields such as project subject information, site selection range coordinates, land scale parameters, and planning control clauses. Field units include planning-specific units such as hectares and square meters.

Constraints Imposed on HTTP Interfaces and External Systems

Since data sources involve multiple government service platforms, interfaces must adapt to identity verification rules across systems to prevent cross-source authentication failures. The diversity of document types and fields requires interfaces to support multi-format parameter transmission and field mapping, ensuring that information from different business documents can be correctly extracted. The irregular data update cycle requires interface configurations to support incremental synchronization to adapt to non-fixed data update schedules. Business handling errors carry serious consequences, so interfaces must be configured with failure retry and exception alert mechanisms to maintain process stability.

Configuration Settings

Reference only; verify against the target FastGPT release and deployment documentation.

Three Common Configuration Mistakes

• The interface returns a 401 Unauthorized error. The cause is that the Authorization parameter does not correctly carry the service account secret key, or the secret key has expired and become invalid.
• The interface receives two duplicate requests, and the Authorization parameter of the second request is incorrect. The cause is that request idempotency is not configured, and the external system does not retain correct authentication information during retries.
• The planning control clause field in the returned responseData is empty. The cause is that the field mapping configuration does not match the actual naming rules of the business document.

How to Verify Successful Configuration

• Initiate a test request, check whether the Authorization parameter is correctly included in the request header, and confirm that the returned status code is 200.
• Pass a preset project number parameter, confirm that business parameters in variables are correctly parsed and used for data query.
• Review the content returned by responseData, confirm that it includes core business required fields such as land scale and site selection range.
• Simulate an interface timeout scenario, confirm that the system triggers the preset retry mechanism and no abnormal data accumulates.
