What the Data for This Category Looks Like
Data for railway operation document and material drafting primarily originates from internal business systems including train operation logs, ticket settlement reports, dispatch order sheets, safety inspection records, and other similar internal business systems. The frequency of data updates is determined by the work process: single-operation documents are updated in real time upon task completion, while batch reports are synchronized on a daily or shift-based dispatch cycle. Document structures include fixed fields: unique document ID, executing work department, effective time, involved operation section, job content details, and approver identifier. Field units include kilometers, passenger trips, work duration, and similar units. The length of a single document ranges from hundreds to thousands of characters.
What Constraints These Characteristics Impose on HTTP Interfaces and External Systems
The multi-source nature of railway operation documents requires HTTP interfaces to support authentication rules for different business systems, to avoid cross-system data synchronization conflicts. Real-time updated operation documents require interface timeout settings optimized for high-frequency call scenarios, preventing dispatch task interruptions. The fixed field and specialized unit document structure requires that interface request and return parameters strictly match preset field names and unit formats, to avoid data parsing errors. The wide range of single document lengths requires interfaces to support segmented reception or batch transmission configurations, to adapt to synchronization needs for document data of varying sizes.
How to Configure Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Interface authentication method | Use Authorization header with Bearer token | Adapts to unified authentication rules of internal railway systems, ensuring data transmission security |
| Request variable configuration | Pass a variables field containing business parameters such as section number, job type | Matches the fixed field structure of railway documents, ensuring accurate mapping of business data |
| Return data processing | Extract core content and metadata from the responseData field | Filters non-business related return information, improving data parsing efficiency |
| Interface timeout setting | 600 seconds | Adapts to long-duration batch document synchronization scenarios, preventing task interruptions mid-execution |
| Cross-origin configuration | Allow a list of internal railway business domain names | Meets call requirements from third-party dispatch systems |
| Single call data volume | 100–200 documents | Adapts to batch processing scale of railway operation documents, preventing interface overload |
Three Common Misconfigurations
- Symptom: Interface returns 404 - Resource not found. Cause: FastGPT API access path is not configured correctly, or the unique identifier of the target collection was entered incorrectly.
- Symptom: Third-party browser calls to the interface are blocked by the browser. Cause: Allowed cross-origin domain names are not configured, or cross-origin rules do not cover the access addresses of business systems.
- Symptom: Document fields returned by the interface lack unit information. Cause: Corresponding business identifiers were not included in the request parameters, resulting in loss of unit fields during data parsing.
How to Confirm Proper Configuration
- Call the test interface, check if the
Authorizationheader is correctly attached, confirm the return status code is 200. - View the
responseDatafield in the interface response, confirm it includes the preset railway document business fields. - Submit a batch request, check if the interface completes the response within the configured timeout period.
- Verify cross-origin requests, confirm that third-party systems can initiate calls normally without blocking.
