What this category of data looks like
Grain reserve declaration materials and case file data mainly comes from the national grain reserve management system, rotation approval ledgers, inbound quality inspection documents, and inventory count reports. Data updates proceed alongside reserve rotation cycles or monthly inventory ledger milestones. Each file typically includes structured fields such as reserve warehouse number, grain type, rotation quantity (unit: tons), approval document number, and inspection report number. It also binds attached files such as corresponding quality inspection scans and approval process records. The overall document structure is fixed, and fields are tightly bound to the business approval workflow.
What constraints these characteristics impose on the "HTTP Interfaces and External Systems" link
Since the data includes structured business fields and bound scan attachments, HTTP interfaces must support both structured parameter passing and file stream upload capabilities. Data updates follow rotation cycles or monthly milestones, so interfaces must adapt to batch pull or scheduled trigger call rhythms to avoid high-frequency invalid requests. Fields are tightly bound to business processes, so interface request parameters must strictly match exclusive fields such as reserve warehouse number and rotation quantity. Missing or incorrectly formatted parameters will interrupt the file review process. Some files are associated with multiple quality inspection attachments, so interfaces must support synchronous transmission verification of batch attachments to avoid missing associated files.
How to set up the configuration
In FastGPT v4.17.0, HTTP interface integration can be completed using the following configuration items:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Request timeout | 600 seconds | Grain reserve files typically include multiple attachments, and complete transmission and review verification require a longer period |
| Batch call limit | First 20 entries | Matches the single update batch size of monthly inventory ledgers, to avoid exceeding the processing capacity of external systems |
| Identity verification method | Authorization header carrying token | Complies with the standard interface security specifications of the national grain reserve management system |
| Request parameter format | Structured JSON, pass reserve warehouse number and rotation quantity fields via variables | Aligns with FastGPT's parameter transfer specifications and external system verification rules |
| Return field filtering | Only retain approval status, inspection results, and file number in responseData | Focuses on core data required for review, reducing data transmission overhead |
| Attachment upload limit | Single attachment no larger than 400 MB, total size no larger than 800 MB | Adapts to file transfer restrictions of most national grain reserve management systems |
Three common mistakes
- Scenario: Interface calls return a 403 status code, or prompt unauthorized access. Cause: The token format in the
Authorizationheader is not correctly configured, or an expired system token is used. - Scenario: Calls to external interfaces time out in restricted network environments, and logs show failed connection establishment. Cause: No system-level proxy is configured to adapt to restricted networks; FastGPT HTTP interfaces do not have built-in proxy forwarding capabilities by default.
- Scenario: The
responseDatareturn field lacks the file number. Cause: Required return business fields are not specified in the configuration, and the external system does not return corresponding data.
How to confirm the configuration is complete
- Send a test request carrying real reserve warehouse number and rotation batch parameters, and check that the interface returns a 200 status code.
- View the
responseDatareturn field to confirm that it includes core business data such as approval status and inspection results. - In restricted network environments, forward requests via the system proxy, and confirm that the interface can complete data transmission normally.
- Submit batch file parameters within 20 entries, and check whether the external system normally receives and processes the requests.
