What the data for this category looks like
Daily documents for this category include injection molding process cards, raw material drying records, mold history logs, first-piece inspection reports, material change and machine cleaning records, and other similar documents. Data sources include resin batch and property sheets, injection molding machine operating parameters, mold temperature controller data, MES system records, and dimensional and appearance inspection results. Data is updated per production batch, each mold change or material swap, and after each shift. Document fields include filling, holding pressure, and cooling window parameters, raw material moisture content, cumulative mold usage hours, dimensional deviation values, and other similar fields, with corresponding units such as megapascals, percentage, hours, and millimeters.
What constraints these characteristics impose on the "HTTP interfaces and external systems" link
High-frequency data updates require interfaces to support high-volume calls with no noticeable delay, to avoid review deviations caused by delayed data synchronization. Multi-source heterogeneous data sources require interfaces to support parameters in different formats, to adapt to the output structures of injection molding machines, mold temperature controllers, MES systems, and other equipment. The diversity of document fields requires the responseData configuration to accurately match the field names of documents such as injection molding process cards and raw material drying records, to avoid missing key review items. Data mutations during mold changes or material swaps require interfaces to support trigger-based pulling, to adapt to real-time synchronization needs during data changes.
How to set the configurations
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {custom interface key} | Used to verify call permissions between external systems and FastGPT, in compliance with HTTP interface security specifications |
variables | {"target_docs":["injection molding process card","raw material drying record"]} | Limits the scope of reviewed documents, matching the core business document types of this category |
responseData | Returns ["process parameter compliance","raw material matching degree","mold status"] | Focuses on key review dimensions for this category, reducing invalid returned content |
| Interface timeout period | 600 seconds | Covers the full process of multi-source data pulling and document cross-comparison, avoiding timeouts caused by large data volumes |
| Single call data limit | First 5 latest records | Matches the update data volume per shift or batch, avoiding excessive interface load |
Three common mistakes
- Symptom: The interface returns empty fields with a 200 status code. Cause: Category-specific review fields are not specified in
responseData, causing FastGPT to fail to extract corresponding data. - Symptom: Interface calls frequently trigger timeouts. Cause: Timeout configuration is not adjusted, and the number of data entries per call is not limited, failing to adapt to this category's high-frequency and multi-source data pulling requirements.
- Symptom: Knowledge base association fails, and uploaded injection molding-specific documents cannot be matched. Cause: Target document type is not limited in
variables, causing the interface search scope to cover irrelevant content and failing to accurately match target documents.
How to confirm the configuration is correct
- Call the test interface, check if returned results include preset review dimension fields, to confirm the
responseDataconfiguration is effective. - Simulate a single mold change or material swap data submission, check if interface response time meets business requirements, and adjust timeout configuration as needed.
- Upload a batch of category-specific documents, call the association interface, confirm search results only include target document content, to verify the limiting effect of
variables. - View interface call logs, confirm the
Authorizationparameter is correctly carried, to verify the permission configuration is valid.
