What this category of data looks like
Urban public transit declaration materials and case review data primarily come from internal operation management systems, vehicle scheduling platforms, and route declaration portals. Data is updated per single declaration batch, with typical single declaration cycles of monthly or quarterly. Document structures include fields such as route number, declaration subject information, vehicle technical parameters, passenger flow operation data, and audit process nodes. Field units include passenger trips, operation kilometers, vehicle seat count, declaration number, and others. Individual case documents range from 800 to 1500 characters in length. Interface configuration for FastGPT v4.17.0 must adapt to the characteristics of this type of data.
Constraints for HTTP Interfaces and External Systems
The batched update characteristic of urban public transit declaration materials and case review data requires HTTP interface calls to align with declaration cycles, to avoid pulling redundant data repeatedly. Individual case documents have long lengths, so interface request timeout thresholds must be adjusted to accommodate large-volume data transmission and parsing processes. Field types and units vary widely, so parsing rules for interface returned data must strictly correspond to preset fields to avoid parsing failures. External systems are internal operation platforms, so interface authentication must match the authentication logic of the original system to ensure call legitimacy.
Configuration Settings
| Configuration Item | Recommended Approach | Basis for This Approach |
|---|---|---|
Authorization | Use the Bearer Token format provided by the public transit operation system, valid for 12 hours | Match the authentication rules of the external system, avoid frequent token refreshes |
variables | Pass two core parameters: route number and declaration batch number | Accurately locate case data for the corresponding batch, narrow query scope |
responseData | Parse returned content in the hierarchy of "route number + declaration date + audit status" | Adapt to the field organization logic of public transit cases, simplify subsequent processing |
| Request timeout period | 600 seconds | Accommodate transmission and parsing time for individual long documents |
| Batch call limit | 10 declaration batches per single call | Avoid overloading single requests, match the typical batch count for monthly public transit declarations |
Three Common Configuration Mistakes
- Phenomenon: Interface calls return the
do_request_failederror, and full data pulling cannot be completed. Cause: The request timeout threshold is set too low, which does not accommodate the transmission and parsing time of long public transit cases, leading to early connection disconnection. - Phenomenon: Multiple interface calls return consistent case data that does not match the actual declaration batch content. Cause: The
variablesparameter does not pass the correct declaration batch number, so the interface always calls the cached default dataset. - Phenomenon: When streaming audit results, the output interval is fixed at 4 seconds and cannot be adjusted. Cause: The streaming output rate parameter of the interface is not configured, the system default transmission interval is used, and it does not adapt to front-end display requirements.
How to Verify Successful Configuration
- Call the preset test declaration batch interface, check if the returned
responseDatamatches the preset field structure of this batch. - View the interface call log, confirm that the
Authorizationparameter has been correctly configured, and no authentication-related errors have occurred. - Initiate a batch call request, verify that the number of returned case files conforms to the single return rules of the external system.
- Simulate a request for an individual long case document, confirm that the interface does not trigger timeout-related errors and the transmission process completes normally.
