What data for this category looks like
Daily data for the spinning and weaving category typically comes from raw fiber inspection, ERP systems, spinning and loom operation data, evenness testers, fabric inspection machines, and similar equipment. Data update frequency aligns with production batches, shifts, and fabric rolls. New documents and records are generated for each batch of raw materials, each shift’s production, and each produced fabric roll. Common documents include cotton blending or material lists, process setup sheets, equipment operation logs, yarn inspection certificates, grey fabric inspection certificates, and fabric defect records. Common fields include fiber fineness (unit: dtex), spinning twist (unit: twists per meter), fabric defect grade, order width, yarn count specification, and other dedicated parameters.
What constraints do these characteristics impose on HTTP interfaces and external systems
This category’s data has batch-based, high-frequency update characteristics, and fields with dedicated units, creating multiple constraints for HTTP interfaces. First, high-volume, high-frequency batch production data requires interfaces to support pagination or bulk synchronization to avoid blocking caused by overly large single request data sizes. Second, fields include dedicated units and process parameters, so interfaces must support passing precise filter parameters to ensure recalled process specifications and technical standards match the current production batch’s requirements. Third, real-time defect records and equipment operation data require setting reasonable timeout thresholds to prevent production data loss from waiting for responses. Fourth, scenarios where multiple users call the interface simultaneously need support for passing user identifiers to isolate chat contexts.
How to set configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Carry a FastGPT API key with the Bearer prefix | Complies with FastGPT v4.17.0 authentication specifications, matches the business system’s key distribution rules |
variables | Pass parameters in the format {"materialType":"cotton spinning","batchNo":"B20240501"} | Filters dedicated process data for spinning batches, narrows the recall scope, and adapts to cotton blending and process setup scenarios |
responseData | Only return the processParam,defectRecord,inspectResult fields | Reduces invalid data transmission, adapts to the business system’s field mapping requirements, and avoids redundant data occupying bandwidth |
| Single request data count | Top 100 entries | Matches the inspection data volume per fabric roll, avoids interface overload and timeout |
| Timeout period | 30–60 seconds | Adapts to delays in equipment data collection, avoids long waits for response bodies |
| User session identifier | Pass using the business system’s user_id | Distinguishes chat contexts for different users, meets multi-tenant business requirements |
Three common misconfigurations
- Calling an interface and waiting a long time for a response body, with a 200 status code but no valid content. The cause is failure to set a reasonable timeout threshold and no pagination for bulk production data, leading to interface blocking when pulling multi-batch process data.
- Using the
Authorizationparameter without adding theBearerprefix, or using an incorrect key format, triggering an authentication failure error. The cause is failure to follow FastGPT’s authentication specifications, confusing key passing rules for different scenarios. - Not passing the
variablesparameter to filter data, resulting in returned process specifications including irrelevant content from other batches that cannot match the current spinning batch’s production needs. The cause is failure to configure parameters based on the batch-based production characteristics of spinning and weaving, expanding the recall scope.
How to confirm configurations are properly set
- Call the interface, then check that the fields returned in
responseDataonly include preset process parameters, defect records, and inspection result content, with no extra fields. - Pass different
variablesparameters to verify that returned process data matches the passed filter conditions such as material type and batch number. - Simulate multiple users passing different user_ids to check that chat contexts are isolated per user, with no cross-user data mixing.
- Call the interface 10 consecutive times to confirm that response times stay within the set timeout range, with no long-term blocking.
