What This Category of Data Looks Like
This category of data originates from design BOMs, silicon steel sheet and insulating material inventory records, vacuum drying equipment operation logs, oil test reports, and high-voltage test records from test stations. Daily generated records include winding and core assembly logs, vacuum drying records, insulating oil reports, partial discharge and withstand voltage test reports, and nameplate parameter tables. A single product’s inspection record typically includes dozens of fields. Records for each batch of materials summarize parameters by batch. Data is updated per single product or per batch of materials, and includes fields such as insulation resistance, partial discharge threshold, drying temperature, and lead connection position. Each field has corresponding engineering units attached.
What Constraints These Characteristics Impose on HTTP Interfaces and External Systems
The ability to update per single product or batch requires interfaces to support precise data retrieval by product ID or batch number, to avoid full synchronization consuming excessive system resources. Multiple types of heterogeneous documents (winding records, test reports, equipment logs, etc.) require interfaces to adapt to structured data returns in different formats. A unified field mapping rule must be agreed upon in advance. Fields with engineering units require interfaces to retain unit information during transmission, to avoid deviations during data parsing. The sensitivity of high-voltage test data requires strict interface authentication, and identity verification must be completed via the Authorization parameter. Frequent single-product data updates require interfaces to support low-latency responses to meet real-time synchronization needs, and avoid inspection process stagnation caused by data delays.
Configuration Settings
The following configurations are adapted for FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Fixed prefix plus enterprise-specific secret, for example Bearer sk-xxxxxx | Meets sensitive authentication requirements for high-voltage test data, to prevent unauthorized access |
| Timeout Period | 600 seconds | Adapts to the full return cycle of large transformer test data |
responseData | Only return fields required for inspection and audit, such as insulation resistance, partial discharge value, drying temperature | Reduces invalid data transmission and lowers interface load |
variables | Pass the batch number of a single product as a query parameter | Precisely retrieve inspection record data for the corresponding batch |
| Field Mapping Rules | Group and map fields by product ID and test type | Adapts to unified parsing requirements for multiple types of heterogeneous documents |
| Data Format Validation | Enable field unit validation | Retain engineering unit information to avoid data parsing deviations |
Three Common Mistakes
- Issue: Interface returns empty
responseDatafield. Cause: Required inspection record fields are not specified in the configuration, resulting in redundant data returned by the interface not being correctly identified. - Issue: Request returns 401 Unauthorized error. Cause: The
Authorizationparameter is not configured correctly, or the secret format does not meet authentication rules. - Issue: Unable to directly communicate with the published application via API. Cause: The
variablesparameter is not configured correctly to pass the product ID or batch number required by the application, or the basic format of the interface call is not matched.
How to Confirm Proper Configuration
- Call the test interface, check if the returned
responseDatacontains preset inspection fields, to confirm that field mapping is correct. - Submit a request with a secret, confirm that the returned status code is 200, with no 401-level authentication errors.
- Pass the specified product batch number, confirm that the returned data only corresponds to the inspection records of that batch, with no redundant data.
- Check the interface response duration, confirm that it meets the preset timeout threshold, with no timeout errors.
