What this category of data looks like
This category of data typically originates from highway maintenance management systems, bridge and tunnel monitoring systems, road administration patrol systems, and traffic flow monitoring datasets. The update frequency is daily. Daily documents include maintenance plans, patrol logs, disease disposal records, road construction permits, and road property damage compensation forms. Document fields include section identifiers, disease types, disposal time limits, permit numbers, compensation amounts, and similar items. Common units are kilometers, square meters, yuan, and workdays.
What constraints these characteristics impose on HTTP interfaces and external systems
The requirement for daily updated data means interfaces must support high-frequency calls, to avoid data lag that reduces the accuracy of policy Q&A. Document field names vary across multiple source systems, so interfaces must support custom field mapping to adapt to data formats from different systems. Sensitive data such as road construction permits and road property damage compensation forms require strict interface authentication configuration to prevent unauthorized access. Patrol logs, disease disposal records and other largely unstructured content mean the responseData returned by the interface must support structured parsing, to facilitate matching valid information for policy Q&A.
Configuration settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Set to the exclusive API key assigned by the platform | Ensure access security for sensitive data such as road construction permits and road property compensation |
| Request timeout | 60-120 seconds | Adapt to network delays when querying data from multiple systems, avoid losing daily updated maintenance data due to timeout |
responseData | Configure as the path for extracting document main text and key fields such as section number and permit number | Adapt to parsing requirements for unstructured documents such as patrol logs and disease disposal records, to facilitate accurate matching of policy basis |
variables | Configure as business variables such as section number and road construction permit number | Enable accurate positioning of policy Q&A for specific sections or projects |
| Interface call frequency | Set to no more than 1000 times per day | Match the daily data update frequency of road administration systems, avoid triggering rate limiting policies of external systems |
Three common misconfigurations
- Symptom: An error of type
getaddrinfo ENis returned when calling a dynamic domain address via the HTTP node. Cause: The correct network access environment is not configured, or the port of the target interface is not open, preventing normal resolution of the target domain name. - Symptom: No data is returned when calling an interface associated with a database, with a prompt that the SQL statement execution failed or fields are empty. Cause: The dedicated field naming convention for highway maintenance data is not matched. For example, using an incorrect field name instead of "section number" leads to mismatched query results.
- Symptom: The
variablesparameter configured for a custom tool does not appear in the workflow interface. Cause: The variable configuration is not correctly bound in the node, or the variable name contains invalid characters causing the system to fail to recognize it.
How to verify successful configuration
- Call the test interface, pass the preset section number variable, check if the returned
responseDatacontains key fields of corresponding documents such as maintenance plans and patrol logs. - View the interface call log, confirm that the
Authorizationparameter is correctly carried, and there are no authentication failure error messages. - Simulate high-frequency daily calls, check if the interface triggers rate limiting or timeouts, adjust the call frequency to a reasonable range.
- Manually enter a road construction permit number as a variable, verify that the interface can return content related to the policy basis for the corresponding project.
