What the data for this category looks like
Commercial real estate marketing content data primarily comes from on-site management systems, leasing ledger systems, local lifestyle business district data platforms, and offline event reporting systems. Data updates follow no fixed cycle. Updates trigger when new retail space is leased, promotional activities launch, or project completion information changes.
The document structure includes four core modules: basic project information, retail space details, leasing ledger, and activity materials. Fields include retail space number (string format, e.g. "L2-012"), floor area (unit: square meters), rental unit price (unit: yuan per square meter per day), activity start and end time (ISO 8601 format), daily peak passenger flow (unit: passenger trips). Some marketing materials such as floor plans and leasing brochures use binary file formats.
What constraints these characteristics impose on HTTP interfaces and external systems
The multi-source nature, non-fixed update cycle, and specific field formats of commercial real estate marketing data create clear constraints for HTTP interface integration. Teams must connect to API endpoints from multiple heterogeneous systems, with separate authentication configurations required for each endpoint. The non-fixed update rhythm requires flexible adjustment of interface polling frequency, rather than enforcing a fixed cycle. Fields include specific units and formats, so mandatory validation of field legitimacy must be implemented in interface requests and response checks. The large file characteristics of marketing materials require interfaces to support chunked upload and resumable upload, to avoid single request timeouts.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
API_REQUEST_TIMEOUT | 120 seconds | Commercial real estate marketing data includes multiple fields such as retail space details and activity materials, so standard timeout durations are insufficient to complete requests |
EXTERNAL_API_AUTH_TYPE | bearer_token | Commercial real estate on-site management and leasing systems commonly use Bearer tokens for interface authentication |
UPLOAD_FILE_MAX_SIZE | 800 MB | Commercial real estate marketing materials include large files such as floor plans and leasing brochures, so large-capacity upload support is required |
API_RETRY_MAX_COUNT | 3 times | Occasional fluctuations occur when connecting to third-party business district data interfaces, and retries can reduce request failure rates |
HTML_PARSE_STRICT_MODE | false | Javadoc-generated interface documents related to commercial real estate often use non-standard formats, and relaxed mode improves parsing success rates |
The parameter values provided on this page are common recommendations used as starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Passing different
pageNumparameters results in identical commercial real estate retail space list data returned by the interface. The cause is that the connected leasing system interface does not correctly implement pagination logic, and only returns fixed cached first-screen data. - After uploading HTML interface documents generated by Javadoc, the knowledge base does not extract any valid content. The cause is that HTML structured parsing configuration is not enabled, or irrelevant page scripts and style code are not excluded.
- Calling an external marketing data interface returns a
504 Gateway Timeoutstatus code. The cause is that a sufficiently long request timeout duration is not configured, and the processing time for multi-field commercial real estate data exceeds the default threshold.
How to confirm configurations are correct
- Send two simulated requests with different pagination parameters, and verify whether the offset of returned data changes with the parameters.
- Upload an HTML document of a commercial real estate leasing brochure, and check whether the knowledge base extracts core fields such as project name and retail space area.
- Simulate a temporary failure of a third-party interface, and verify whether the system automatically initiates a retry request.
- View interface request logs to confirm that each request carries authentication credentials that match the configured settings.
