FastGPT v4.17.0 aligns with the configuration standards on this page.
What this category's data looks like
The business data for hazardous chemicals storage and transportation mainly comes from local emergency management department filing databases, enterprise warehouse management systems (WMS), and transportation dispatch logs. The update rhythm is full synchronization every day at midnight plus real-time incremental push. A single record includes fields such as common hazardous chemical name, UN code, storage location, maximum storage volume, compliance validity period, and emergency response procedures. Field units include tons, cubic meters, degrees Celsius, hours, and similar. The length of a single record is mostly between 200 and 800 characters. Some entries with attachment links will exceed this range.
What constraints do these characteristics impose on the "HTTP Interfaces and External Systems" link
The daily full synchronization plus real-time incremental update rhythm requires interfaces to support resumable uploads and incremental synchronization verification to avoid duplicate pushes or missing critical compliance data. The multi-field, multi-unit structure requires interface request parameters to carry field mapping configurations to convert internal enterprise custom fields to FastGPT standard fields. The single-record length range requires the batch data limit per interface request to adapt to 200-800 characters per entry, to avoid truncating core information such as UN codes and emergency response points. Additionally, the regulatory attribute of hazardous chemicals data requires that inquiry responses returned by the interface strictly match the filed data, and field content must not be modified without authorization.
How to set the configurations
| Configuration Item | Recommended Value | Rationale for This Value |
|---|---|---|
Authorization | Bearer {enterprise filing API key} | Hazardous chemicals data is regulated sensitive data. Standard Bearer token authentication is required to prevent unauthorized access |
variables | {"unit_mapping": {"storage": "tons", "validity": "days"}} | Adapts to the multi-unit field characteristics of hazardous chemicals storage and transportation data, unifying data display units |
responseData | Only return the un_code, product_name, emergency_handle fields | Reduce interface transmission volume and avoid redundant data affecting inquiry response speed |
| Batch request limit | 50 entries per request | Adapts to the 200-800 character length of single-record data, avoiding a single request exceeding the interface transmission threshold |
| Interface timeout period | 30 seconds | Hazardous chemicals emergency response related data requires rapid response. Excessive timeout will affect inquiry response efficiency |
| Incremental sync switch | Enable real-time incremental mode | Adapts to the daily full synchronization plus real-time incremental update rhythm, ensuring data timeliness |
Three common mistakes
- Phenomenon: Hazardous chemicals compliance certificate images uploaded via the interface fail to load or return a resource not found prompt, while images on the official inquiry page display normally. Cause: The interface request does not carry the correct image storage path mapping parameter, causing FastGPT to fail to associate with the actual stored image resources.
- Phenomenon: The inquiry response fields returned after calling the interface are empty or display incorrect units. Cause: The unit mapping rules in
variablesare not configured, causing data display to be inconsistent with the internal enterprise storage units. - Phenomenon: Interface calls frequently trigger timeout errors. Cause: The number of batch data entries per request exceeds the configured limit, causing interface processing time to exceed the
30 secondstimeout threshold.
How to confirm the configuration is complete
- Send a test request for a single hazardous chemicals data entry, check if the fields returned in
responseDatainclude the content specified in the configuration. - Upload compliance certificate images, verify that images load normally via the FastGPT inquiry page, and compare whether the image encoding formats of the interface request and the official page match.
- Simulate a batch request, check if the interface response time meets business requirements and there are no timeout errors.
- View interface logs to confirm that the
Authorizationauthentication parameter is correctly carried, and there are no unauthorized access errors.
