What Data for This Category Looks Like
Data for this category originates from customer color swatches, formula libraries, dye chemical batch ledgers, dye vat control systems, colorimeters, setting machine equipment, and environmental monitoring systems. Daily documents include dyeing formulas, chemical weighing records, dye vat operation curves, proofing confirmation sheets, color difference reports, setting process sheets, and sewage discharge ledgers. Data updates follow a per-vat, per-batch, or per-shift schedule. Individual data entries include fields such as vat number, batch number, color difference value, dye chemical dosage, process temperature curve, and more. Units include g/L, ℃, seconds, mg/L, and other standard units.
Constraints for HTTP Interfaces and External Systems
Data in this category updates frequently, and per-vat, per-batch data is independent. Interfaces must support precise data pulling by vat number or batch number to prevent cross-batch data mixing. There are multiple types of daily documents. Interfaces must support parsing multi-format data including text, curve charts, and test reports. Many professional chemical parameter fields are used. Interface requests must carry standardized parameter mappings to ensure no field mismatches. Environmental monitoring data must be synchronized in real time. Interface response delays must align with production rhythms. Timeouts will disrupt the overall progress of tender document and quotation preparation.
Configuration Recommendations
The following recommendations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Use a token with the Bearer prefix, valid for 7 days | Matches the data permission control logic of dyeing factories, avoids frequent token refreshes interfering with interface calls |
variables | Bind vat number, batch number, and customer color number as dynamic variables | Adapts to the need for precise pulling of per-vat or per-batch data, avoids mixing cross-batch data |
responseData | Only return fields for dyeing formulas, color difference reports, and process curves | Reduces invalid data transmission, focuses on core business data required for tendering and quotation |
| Concurrency limit | Set to no more than 5, based on actual measurement | Matches the concurrency limits of cloud service interfaces, avoids returning 429 errors |
| Timeout period | 600 seconds | Adapts to the parsing and pulling duration of large-volume dye vat curves and test reports |
| Data filtering rules | Only synchronize production data from the last 30 days | Controls the volume of interface returned data, adapts to the short-term historical data needs of tender documents |
Three Common Mistakes
- Interface calls return a 429 status code. Cause: No concurrency limit is configured, and request volume exceeds the cloud service interface's concurrency limit.
- Production data fields returned by the interface are missing or mismatched. Cause: Dynamic variables in
variablesare not correctly bound, pulling historical data that does not match the current tender batch. - Interface file parsing takes too long. Cause: Non-core business fields are not filtered via
responseData, with redundant data consuming excessive parsing resources.
How to Verify Successful Configuration
- Send a request with the
Authorizationtoken, verify the returned response header includes the correct permission verification identifier. - Pass the
variablesparameters for a specified vat number, confirm the returned dyeing formulas and color difference reports match the corresponding production ledgers. - Send multiple concurrent requests, verify no 429 errors are returned and interface response duration meets expectations.
- Check the
responseDatafield returned by the interface, confirm it only includes core business data required for tendering and quotation.
