What Data for This Category Looks Like
Data for this category originates from steel coil labels and quality certificates in stamping workshops, operation logs of stamping presses and feeders, mold management systems, workshop MES systems, and coordinate measuring machine and fixture inspection data. Documents including stamping operation instructions, material utilization rate sheets, mold inspection logs, first and last piece records, dimensional inspection reports, and mold change records are retained daily. Updates are triggered per coil of material, per production batch, or each mold change. Fields include furnace batch number, equipment operating duration, mold usage count, dimensional deviation value, material utilization rate, and other relevant fields. The format is dynamically adjusted based on production scenarios.
Constraints on HTTP Interfaces and External Systems
Data for this category comes from multiple dispersed sources, covering various external systems such as device logs, management systems, and inspection reports. Interfaces must support docking with different types of data sources. Data update trigger nodes are not fixed, and are dynamically triggered based on coils, production batches, and mold change operations. Interfaces must support on-demand calls to adapt to dynamic update rhythms. Single-batch data volume varies with production scale. Interfaces must support variable-length request and response content. Data fields are adjusted according to production scenarios. Interfaces must support flexible field mapping to avoid ledger summary failures caused by missing fields. In high-frequency call scenarios, interfaces must set reasonable response duration thresholds to prevent disruption to workshop production progress.
How to Set Configurations
The content on this page is compatible with FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {third-party system API key} | Complies with identity authentication specifications for third-party APIs, and adapts to authentication requirements for various external systems |
variables | {"batch_id": "{{batchId}}", "coil_no": "{{coilNumber}}"} | Binds dynamic variables such as production batch number and steel coil number, adapting to interface calls triggered by coils of material or mold change nodes |
responseData | Extract the data array under the root node | Adapts to response formats of various external systems, facilitating subsequent field extraction for ledger summary |
| Request timeout duration | 30–60 seconds | Pulling data for this category involves multiple source systems, so sufficient response duration must be reserved to avoid call failures caused by network latency |
| Request retry count | 2 times | Workshop networks have occasional fluctuations; a small number of retries can reduce the probability of call failures and avoid repeated triggering of production nodes |
| Field mapping rules | Match external response fields according to production ledger fields | Data fields for this category are adjusted according to production scenarios, so flexible mapping is required to ensure complete ledger data |
Three Common Mistakes
- Symptom: Interface calls return a 401 status code, prompting authentication failure. Cause: The
Authorizationparameter is not configured correctly, and authentication information meeting third-party system requirements is not included. - Symptom: Production ledger fields are empty after an interface response, with no valid data filled in. Cause: The
responseDataparameter is not configured correctly, and valid data fields returned by the external system are not accurately extracted. - Symptom: An interface call is triggered when the production process starts, but current batch production data is not obtained. Cause: Dynamic variables for the current production batch are not bound through the
variablesparameter, and correct business identifiers are not passed during the interface call.
How to Confirm Configurations Are Correct
- Manually trigger an interface call, view the returned response content, and confirm that the
responseDataparameter correctly extracts the expected fields. - Pass preset
variablesparameters, and check whether bound dynamic information such as production batch number and steel coil number is correctly carried in the interface request body. - Simulate a workshop network latency scenario, verify whether the interface can complete the response normally within 30–60 seconds, and confirm that the timeout configuration is reasonable.
- After calling the interface, check the logs of the external system to confirm that the
Authorizationauthentication information is correctly identified, and no authentication error messages appear.
