What data for this category looks like
Data for hazardous chemicals storage and transportation mainly comes from on-site storage monitoring systems, inventory management ledgers, patrol reporting systems, and approval workflow platforms. Data sources are scattered, and update rhythms vary significantly. Real-time temperature, humidity, and liquid level data updates every second. Batch inventory ledgers update daily in bulk. Patrol records and approval statuses update after each shift or single job.
The structure of individual data documents is fixed. It includes fields such as unified hazardous chemical number, storage area number, current inventory (unit: tons), environmental temperature and humidity (units: ℃ and %RH), patrol time, and approval status. Field enumeration values are fixed, with no dynamically expandable fields.
What constraints these characteristics impose on HTTP interfaces and external systems
Scattered multi-data source access requires interfaces to support multi-endpoint batch calls. This avoids timeouts caused by connecting too many systems in a single request.
Fields include fixed units. Interface returned data must retain complete unit information. Otherwise, external systems cannot correctly parse inventory and environmental parameters.
Real-time monitoring data updates at a high frequency. The size of the dataset returned by a single interface request must be limited to prevent transmission overload.
Approval status is a fixed enumeration value. Interface request parameters must strictly validate the enumeration value range to avoid invalid requests.
Hazardous chemical data has high sensitivity. Interface authentication must use fixed keys to ensure transmission security and prevent unauthorized access.
Configuration settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Request timeout | 30 seconds | Adapts to the short-interval update requirements of hazardous chemical real-time monitoring data, and avoids connection timeouts |
Authorization | Fixed static key | Meets the high sensitivity requirements of hazardous chemical data, and ensures authentication stability |
variables | Map core hazardous chemical fields | Ensures alignment between interface request parameters and the field format of external systems |
| Single request return count | Top 20 entries | Limits data transmission volume, and adapts to the fast response requirements of real-time data |
responseData | Retain field unit suffixes | Matches the fixed unit characteristics of hazardous chemical data, and avoids external parsing errors |
| Retry count | 3 times | Addresses single request failures caused by network fluctuations, and ensures interface call success rate |
Three common configuration mistakes
- Symptom: Interface calls return a 504 Gateway Timeout status code. Cause: The timeout setting was not adjusted for the update frequency of hazardous chemical real-time data. Using the default long timeout value causes connections to be blocked by intermediate nodes.
- Symptom: API call results differ significantly from online chat results, and returned data lacks unit information. Cause: The field mapping rules for
responseDatawere not correctly configured. The unit suffixes for inventory and temperature and humidity were not retained. - Symptom: Feishu webhook triggers no response, and approval status changes are not synchronized. Cause: The enumeration values for hazardous chemical approval status were not correctly mapped to the
variablesrequest parameters. This causes external systems to fail to recognize status parameters.
How to confirm configuration is complete
- Call the interface to obtain a single hazardous chemical data entry. Verify returned results include complete fields and unit information such as tons, ℃, and %RH.
- Send batch requests. Verify the number of returned data entries does not exceed the configured single request limit, with no data truncation.
- Send a request without the correct
Authorization. Verify a 401 Unauthorized status code is returned, confirming authentication configuration is effective. - Simulate a hazardous chemical approval status change, trigger a webhook push. Verify external systems receive correct status parameters.
