What data for this category looks like
Data for highway operation inquiry and response comes primarily from road network operation and maintenance systems, toll settlement platforms, offline customer service ticket databases, and official service guideline documents. Update frequency varies by data type: real-time traffic and traffic control information is updated per second. Service procedures and fee standard documents are updated quarterly. User-submitted inquiry tickets are synced in real time as submitted. Single inquiry response data includes fields such as service site code, item category, handling procedure, required materials, time limit for completion, and inquiry response time limit. Most field units follow standard government service specifications. For example, the time limit for completion uses "workdays" as its unit, and material lists use "items" as their counting unit.
What constraints these characteristics impose on HTTP interfaces and external systems
The per-second update requirement for real-time traffic data means HTTP interfaces must set reasonable timeout thresholds to avoid returning outdated information. The quarterly update requirement for service procedure documents means interfaces must be configured with regular synchronization verification mechanisms. This ensures connected official document versions match the latest published content. The real-time sync requirement for ticket data means interfaces must support batch writing and incremental pulling. This prevents timeouts caused by overly large single request data volumes. Standardized units for different fields require interfaces to complete format verification before data transmission. This stops non-standard unit values from entering the knowledge base and affecting the accuracy of subsequent inquiry responses. Multi-source data access requires unified interface authentication rules. These rules must match the existing security control requirements of highway operation systems.
How to set configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer highway operation system exclusive API key | Matches the authentication specifications of highway operation systems to ensure the legality of interface calls |
variables | { "service_scope": "regional road network", "max_result": 20 } | Adapts to the regionalized inquiry needs of highway operations, limits the number of returned results to avoid interface overload |
responseData | Extract fields: site code, item category, handling procedure, time limit for completion | Only retains core fields required for inquiry responses, reduces transmitted data volume |
| Request timeout threshold | 60 seconds | Adapts to the per-second update rhythm of real-time traffic data to avoid returning outdated information |
| Incremental sync switch | Enabled | Matches the real-time update requirements of ticket data, only syncs newly added or modified inquiry data to reduce interface load |
| Field format verification | Mandatory unit field verification | Matches the standardized unit requirements of highway operation data to ensure knowledge base data format compliance |
Three common mistakes
- An HTTP interface call returns a 401 unauthorized error. Cause: The
Authorizationparameter is not configured correctly, and an incorrect API key or authentication format is used. - An external system call to the interface returns a specified error prompt, while the FastGPT application's internal interface test works normally. Cause: The external system does not correctly pass authentication parameters, or the request header format does not match the authentication rules configured in FastGPT.
- The unit fields in the inquiry data returned by the interface do not meet requirements. Cause: The field format verification configuration is not enabled, and no compliance verification is performed on unit values returned by the highway operation system.
How to confirm the configuration is complete
- Call the interface to obtain a single piece of inquiry data, and check whether the returned fields match the extraction list configured in
responseData. - View the interface request log to confirm that the
Authorizationparameter is correctly carried and the format meets requirements. - Simulate submitting a test inquiry ticket, and check whether the interface synchronously receives and returns correct service procedure information.
- Adjust the parameter values in
variablesto verify whether the number of interface returned results changes with the configuration.
