HTTP Interfaces and External Systems for Commercial Property

What This Category’s Data Looks Like

Commercial property marketing content data primarily originates from investment operation ledgers, offline material scans, online event announcements, and tenant cooperation agreements. Updates are triggered on demand alongside investment adjustments and holiday event launches, with no fixed cycle. Document types include PDF-format investment manuals, Excel-format tenant lists, single-page event posters, and more. Structured data fields include shop number, floor area (square meters), business type, rental unit price (yuan per square meter per day), and contact number. Unstructured documents include event rules, settlement guidelines, and other content. The word count and file size of individual documents vary widely.

Constraints Imposed on HTTP Interfaces and External Systems

The multi-type and on-demand update nature of commercial property marketing content creates multiple constraints for HTTP interfaces and external systems. Multi-format documents including PDF investment manuals, Excel tenant lists, and event posters require interfaces to support multi-type file upload and parsing. Structured data includes fields with fixed units such as floor area (square meters) and rental unit price (yuan per square meter per day). Interfaces must validate field format and unit legitimacy. On-demand update rhythms require interfaces to support one-time active synchronization, without relying on fixed-cycle pulling. Bulk tenant data import scenarios require interfaces to support batch submission, while requiring reasonable timeout threshold configuration to avoid timeout during high-load processing.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`1000 MB`	Commercial property investment manuals are mostly multi-page PDF files, with typically large individual file sizes
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Long document parsing requires sufficient processing time to avoid mid-process timeout interruptions
`BASE_URL`	`Public network access address after FastGPT deployment`	Specifies the base path for HTTP requests, matching platform API call specifications
`AUTHORIZATION`	`Key obtained from the FastGPT system API key management module`	Completes interface identity verification, complying with platform security configuration requirements
`BATCH_SYNC_MAX_COUNT`	`500 entries`	Adapts to bulk tenant data import scenarios, balancing interface load and synchronization efficiency
`FIELD_VALIDATE_ENABLE`	`Enabled`	Validates structured data field format and units, ensuring compliance with commercial property ledger specifications

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Misconfigurations

Phenomenon: 413 status code returned when calling the file upload interface. Cause: UPLOAD_FILE_MAX_SIZE not correctly configured, and local file size exceeds the maximum limit allowed by the interface.
Phenomenon: 404 status code returned when configuring an external model interface in FastGPT 4.9.0. Cause: BASE_URL not correctly filled as the deployed external model gateway address, or the AUTHORIZATION key obtained from the system not used.
Phenomenon: 500 status code returned when calling the /api/core/dataset/update interface, while normal access to the interface via a browser is possible. Cause: Correct AUTHORIZATION request header not included, or request parameter format does not meet interface requirements.

How to Verify Successful Configuration

A small-volume single-file upload request is sent. Confirm the interface returns a 200 status code, and the file parsing result includes correct metadata.
After configuring BASE_URL and AUTHORIZATION, call the external model test interface. Confirm returned results meet expectations.
Submit a small amount of structured test data. Check the interface’s returned verification results, and confirm the field verification function operates correctly.
Send a batch data synchronization request. Check the interface’s returned synchronization result, and confirm the batch submission function runs normally.
