What Data for This Category Looks Like
Data for this category originates from the full production workflow of enterprises in coatings, resins, additives, agrochemical intermediates, and specialty chemicals. Daily documentation includes batch production instructions, feeding review sheets, reaction process records, site cleaning records, inspection reports, and deviation and change orders. Data sources cover formula and process libraries, raw material batch ledgers, reactor DCS systems, weighing systems, LIMS laboratory management systems, and warehouse systems. Data is updated per batch production and each critical step. Documents linked to a single batch include fields such as batch number, feeding quantity, reaction temperature, pressure, and inspection results. Field units include kilograms, degrees Celsius, pascals, and similar units. Some classified process documents require permission-based access isolation.
Constraints on HTTP Interfaces and External Systems From These Characteristics
The multi-batch data updated per critical step requires HTTP interfaces to support precise retrieval of corresponding documents by batch ID. This avoids redundant transmission caused by full data pulls. The need for multi-source data access means interfaces must adapt to return formats from different systems including formula libraries, DCS, and LIMS. It also requires support for custom field filtering to extract core review content. The high frequency of batch updates requires interfaces to use reasonable timeout and retry strategies. This handles short-term fluctuations in production systems. The permission isolation requirement for classified process documents mandates strict identity verification via the Authorization field. This prevents unauthorized access. The large number of associated documents per single batch requires interfaces to support batch requests and paginated returns. This avoids overload from single requests.
Configuration Guidelines
The configuration rules on this page apply to FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Timeout duration | 300 seconds | Matches the average processing duration for documents linked to a single batch |
| Request header configuration | Include the Authorization field, with a value bound to the environment | Ensures permission isolation for interface access |
| Request variables | Pass batch number and raw material type parameters from variables | Enables precise retrieval of production documents for the target batch |
| Return data processing | Only return core fields from responseData | Reduces transmission load for interface calls |
| Retry count | 2 times | Handles short-term fluctuations in production systems |
| Batch request threshold | 10 items per request | Matches the range of associated document quantities per single batch |
Three Common Configuration Mistakes
- A
URIError: URI malformederror is thrown when calling login or data interfaces. This occurs because the request URL contains unencoded special characters. Examples include Chinese characters or special symbols in batch numbers that have not been URL-escaped. - A 413 Request Entity Too Large status code is returned when calling an interface. This happens because the volume of document data or parameters uploaded in a single request exceeds the interface's preset limit threshold.
- Interface calls fail during local deployment, with prompts for unauthorized access or failed connections. This is caused by incorrect configuration of the
AIPROXY_API_ENDPOINTandAIPROXY_API_TOKENparameters. This prevents request forwarding via the proxy.
How to Verify Proper Configuration
- Send a test request with valid batch parameters. Check if the returned
responseDataincludes expected core fields such as feeding quantity and reaction temperature. - Verify that the
Authorizationfield is correctly included. Send a test request without proper permissions, and confirm that a corresponding permission exception status code is returned. - Adjust the volume of request parameters to simulate a large request package. Confirm that a 413 error is not triggered.
- Simulate short-term fluctuations in production systems. Disconnect the interface connection and retry, then confirm that the interface automatically resumes the request according to the configured retry count.
