What Data in This Category Looks Like
Work consultation data for refining and chemical production mainly comes from four types of systems: device process DCS logs, production scheduling work order system, safety inspection records, and equipment operation and maintenance logs. Data update frequencies vary: scheduling work orders are generated in real time with events, process parameters are updated in batches every 15 minutes, inspection records are submitted per shift, and operation and maintenance logs are updated when equipment abnormality events occur. The document structure of a single consultation data includes six core fields: consultation type, associated device ID, timestamp, reporter, problem details, and processing progress. Field units must comply with refining and chemical industry standards, such as pressure in MPa, temperature in ℃, flow rate in m³/h, and work order numbers uniformly use the LY-YYYYMMDD-XXXX format.
What Constraints These Characteristics Impose on the "HTTP Interfaces and External Systems" Link
Data sources are scattered across multiple independent systems, requiring HTTP interfaces to support authentication and data pulling from multiple external systems, with unified authentication completed via the Authorization parameter. The differences in update frequencies of different data require the interface to adapt to both real-time polling and batch synchronization call modes. The standardization requirements for fields and units require field mapping and unit conversion during interface requests and responses, to avoid data parsing failures caused by format mismatches. Refining and chemical production data involves production safety and compliance information, so interface calls must strictly follow permission control rules to prevent sensitive data leaks.
How to Configure
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Request Header Authentication | Bearer {Refining and Chemical Production System Exclusive API Key} | Complies with the authentication standards of external systems in the refining and chemical industry, ensuring business data security |
| Variable Mapping | Bind associated device ID and time range parameters via variables | Matches the business field rules of work consultation for refining and chemical production, enabling accurate retrieval of target data |
| Response Data Filtering | Only return processed work consultation entries via responseData | Filters invalid information to improve business processing efficiency |
| Timeout Setting | 600 seconds | Adapts to the delay characteristics of data transmission in refining and chemical systems, avoiding interface call interruptions |
| Unit Conversion | Uniformly convert to standard units of the refining and chemical industry (MPa, ℃, m³/h) | Ensures parameters returned by external systems can be correctly parsed |
| Retry Strategy | Retry 3 times after failure, with a 10-second interval | Addresses network fluctuations or temporary system faults in refining and chemical systems, ensuring call stability |
Three Common Mistakes
- Phenomenon: The interface call returns a 401 unauthorized error, and the log shows authentication failure. Cause: The
Authorizationparameter is not configured correctly, or an API key that does not match the refining and chemical system is used. - Phenomenon: The body parameter of the HTTP request in the workflow cannot be converted into an available variable. Cause: Variable binding is not enabled in the workflow configuration, or the key name of the body parameter does not correspond to the preset variables.
- Phenomenon: The consultation data returned by the interface has missing fields or incorrect units. Cause: The variable mapping rules are not configured correctly, and the field and unit standards of refining and chemical production data are not matched.
How to Confirm the Configuration is Complete
- Call the test interface, check that the returned authentication status code is 200, confirming that the request header authentication configuration takes effect.
- Pass the preset associated device ID and time range parameters, check that the returned data fields match the refining and chemical production business rules.
- Simulate timeout or abnormal request scenarios, check whether the system triggers the preset retry strategy.
- View the workflow variable binding log, confirm that the body parameter has been correctly parsed into callable workflow variables.
