What data for this segment looks like
This segment’s data covers daily documents including dyeing formulas, chemical dosing records, dye vat curves, proofing confirmations, color difference reports, setting process sheets, and sewage ledgers. Data sources include customer color samples, formula libraries, dyeing chemical batches, dye vat control equipment, colorimeters, setting machines, and environmental monitoring systems. Data updates occur per vat, per batch, or per shift. Core fields include dye vat number, chemical batch number, color difference values, setting temperature, drainage pH value, and more. Units include ℃, mg/L, vat runs, and others.
What constraints these characteristics impose on HTTP interfaces and external systems
High-frequency updates per vat and batch require interfaces to support precise queries by business identifiers, to avoid redundant data returns. Multi-source data association needs require interfaces to aggregate results from multiple data sources such as dye vats, colorimeters, and environmental monitoring systems. Rich field structures for documents require interfaces to support specifying returned fields, to reduce invalid data transmission. Intranet deployment scenarios in factories require interfaces to support proxy configuration, to adapt to network access restrictions in intranet environments.
How to set configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Use a fixed Bearer token with a value of 128–256 characters | Matches external system interface authentication requirements, and reduces token leakage risks |
variables | Include vat number and chemical batch number as core input parameters | Aligns with per-vat and per-batch traceability requirements, to narrow query scope |
responseData | Only return color difference reports, dye vat curves, and environmental monitoring data | Reduces invalid data transmission, and adapts to core traceability fields in dyeing and finishing scenarios |
| Timeout | 60–120 seconds | Adapts to query times for dye vat curves and historical formulas, to avoid query failures from short timeouts |
| Maximum returned entries | Top 10 entries | Matches typical data volume per shift or batch, to avoid returning excessive redundant records |
| Data rearrangement | Sort by detection time in descending order | Prioritizes displaying the latest quality detection data, aligns with time-based traceability priorities |
This configuration applies to FastGPT v4.17.0
Three common configuration mistakes
- Phenomenon: Calling external dye vat data interfaces fails in an intranet environment. Requests cannot be forwarded via proxy. Logs show connection timeouts. Cause: Proxy-related parameters are not configured, or the proxy address format does not meet interface requirements.
- Phenomenon: Interface calls return a 403 authentication failure status code. Cause: The
Authorizationparameter is not configured correctly, or the token value falls outside the128–256 characterscompliance range. - Phenomenon: Query results are empty, with no valid data in returned fields. Cause: Core
variablesparameters such as vat number and chemical batch number are not passed, or the parameter format does not match external system requirements.
How to confirm configuration is complete
- Call the test interface, pass preset vat number parameters, and check if returned results include the color difference report and dye vat curve fields specified in
responseData. - View interface call logs, confirm that the
Authorizationparameter is correctly carried, and that the token format meets the128–256 charactersrequirement. - Simulate high-frequency calls, check that interface response times fall within the 60–120 second preset range, with no timeout errors.
- Configure proxy parameters in the intranet test environment, confirm that external interface requests can be forwarded normally and return valid data.
