What this category of data looks like
This category of data comes from formula and process libraries, raw material batch records, reactor DCS systems, weighing systems, LIMS laboratory management systems, and warehouse systems of specialty chemical enterprises including coatings, resins, additives, and agrochemical intermediates. Daily documents include batch production instructions, feeding review sheets, reaction process records, site cleaning records, inspection reports, and deviation and change orders. Data is updated per production batch and each key process step. Data fields include batch number, raw material batch number, reaction temperature, feeding amount, inspection results, and more. Units involve mass units, volume units, time, temperature, and others. Due to formula confidentiality requirements, access permissions for some core process parameters are limited to a restricted scope.
What constraints these characteristics impose on HTTP Interfaces and External Systems
The multi-variety production mode with batch switching requires interfaces to support dynamic binding of process parameters and permission scopes corresponding to the target batch. The multi-source data collection requirement requires interfaces to be compatible with return formats of different systems, adapting to different interaction logics such as real-time data push from DCS and inspection result callbacks from LIMS. The batch-by-batch data update requirement requires interfaces to support precise querying by batch ID to avoid mixing of cross-batch data. The formula confidentiality feature requires interfaces to perform strict permission verification via the Authorization parameter, limiting the return scope of sensitive process parameters. Frequent single-batch data requests require interfaces to be configured with reasonable timeout and retry mechanisms to meet the real-time requirements of production links.
How to configure settings
This page is written based on FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Authorization | Bearer ${Enterprise-specific API key} | This category of data involves formula confidentiality and production-sensitive information, so this parameter is required to implement strict identity verification and permission isolation |
variables | {"batchId": "Current production batch number", "productType": "Current synthesis category"} | This category uses batch-based production, so variables are needed to dynamically bind process, raw material, and inspection data corresponding to the target batch |
responseData | Return only non-sensitive fields such as batch number, feeding amount, reaction temperature, and inspection results | Formula confidentiality requirements restrict the scope of sensitive process parameters returned by the interface to avoid leakage of core technology |
| Single request timeout | 300–600 seconds | Batch synthesis reaction steps take a long time, so this configuration must adapt to delays in real-time data collection during production |
| Interface retry count | 2–3 times | Production data collection requests may fail due to temporary system fluctuations, and retries can reduce the risk of data loss |
Three common configuration mistakes
- Phenomenon: The interface returns the "Knowledge base ID is invalid" error with a 400 status code. Cause: The knowledge base ID associated with the target batch was not passed via the
variablesparameter, or the global variable was not bound to the exclusive knowledge base of the current production batch. - Phenomenon: The interface returns empty fields after being called, and feeding review sheet data cannot be obtained. Cause: No batch ID was used as the query condition, and full production data was requested directly, resulting in no matching documents for the current batch.
- Phenomenon: The interface call times out with a 504 status code. Cause: No reasonable timeout period was set, and single-batch data collection for batch synthesis takes a long time, so the default timeout duration is insufficient to complete data retrieval.
How to confirm the configuration is correct
- Call the interface with a test batch ID, and check that the returned
responseDataonly includes preset non-sensitive fields, with no unauthorized sensitive process parameters. - View the interface logs to confirm that the
Authorizationparameter was correctly carried and passed identity verification, with no permission error prompts. - Pass different
variablesbatch parameters to verify that the interface returns data that dynamically changes with the batch, with no cross-batch data mixing. - Simulate temporary network fluctuations in the production link to check whether the interface automatically initiates retry requests according to the configured retry count, with no consecutive failures.
