This document is written based on FastGPT v4.17.0.
What Data for This Category Looks Like
Data sources for this category include material grades, customer technical requirements, temperature control instruments, furnace temperature uniformity testing equipment, hardness testers, metallographic equipment, and production MES systems. Data updates per furnace load and per batch. Daily documents include heat treatment process cards, charging charts, furnace temperature curves, hardness and metallographic reports, equipment inspection forms, and exception handling sheets. Data fields include furnace temperature setpoints and measured values, holding time, material hardness values, and metallographic structure types. Units include degrees Celsius, hours, HRC, and others.
What Constraints Do These Characteristics Impose on HTTP Interfaces and External Systems
The data for this category has high-frequency updates, multiple dispersed sources, and diverse formats. These characteristics create multiple constraints for HTTP interface and external system integration. The update rhythm per furnace load and per batch requires interface call frequency to match production tempo, to avoid request backlogs that cause data delays. Multi-type documents including curves, tables, and text require interfaces to support multi-format data transmission and structured parsing. Data sources cover production equipment and management systems, so interfaces are needed to complete unified access to multi-source data. Specific units and terms for professional fields require interface parameters to clearly match business definitions, to avoid data parsing deviations.
How to Configure the Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer sk-xxxxxx | Verify caller identity, comply with security access specifications for industrial production scenarios |
variables | {"furnace_temp": "℃", "hardness": "HRC", "batch_no": "炉批号"} | Bind core business units and fields for heat treatment scenarios, unify data transfer formats |
responseData | Return three fields: furnace temperature, hardness, exception flag | Filter non-core data, adapt to the fast reading needs of production systems |
| Interface timeout period | 30 seconds | Match the real-time requirements of furnace temperature collection, avoid excessive waiting that affects production tempo |
| Automatic retry count | 2 times | Respond to temporary network fluctuations, reduce the probability of production data synchronization failures |
Three Common Misconfigurations
- Phenomenon: A 401 Unauthorized status code is returned when calling the interface, and the system shows key verification failed. Cause: The
Authorizationparameter is not configured correctly, the key format does not follow the Bearer prefix specification, or the key is not entered correctly in the system. - Phenomenon: The interface returns an empty result after being called, and production data for the target furnace load cannot be obtained. Cause: The correct furnace batch number or business identifier is not passed via the
variablesparameter, so the system cannot match the target data. - Phenomenon: Timeouts occur when calling the interface via FastGPT deployed through intranet penetration. Cause: The delay of the penetration link is too high, and the interface timeout configuration is not adjusted based on the link status, causing the request to not complete a response within the allowed time.
How to Confirm the Configuration Is Correct
- Call the interface with test furnace batch numbers and business parameters, check if the returned
responseDataincludes the preset core business fields. - Simulate high-frequency calls in a production scenario, observe if the interface return status codes remain within normal ranges with no consecutive errors.
- Verify that the interface data fields and units received by the external system match the
variablesparameter configured in FastGPT. - Disconnect the temporary network connection and trigger an interface call, confirm that the system executes the retry logic according to the configured automatic retry count.
