What this category of data looks like
The data for this category typically comes from highway maintenance management systems, bridge and tunnel monitoring systems, road patrol systems, and traffic flow monitoring data, with a daily update frequency. Daily documents include maintenance plans, patrol logs, defect disposal orders, road construction permits, and road property damage compensation forms. Document structures usually include fields such as section identifiers, facility status, disposal process nodes, and involved parties. There is no fixed unified format, and it is necessary to match the interface field requirements of external systems.
What constraints do these characteristics impose on the HTTP interfaces and external systems link
Multi-source data access requires the interface to support parsing field formats from different systems, to avoid deviations in document content caused by field mapping errors. The daily update frequency requires the interface call frequency to adapt to the daily data synchronization rhythm, and should not be too frequent to occupy external system resources. There are various document types, so the interface needs to support different request body structures to adapt to the submission of different documents such as maintenance plans and patrol logs. Additionally, because documents are related to road safety, fund usage, and law enforcement compliance, the interface must have strict parameter verification and failure retry mechanisms to ensure the accuracy and stability of data transmission, and avoid subsequent business problems caused by data errors.
How to configure the settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Bearer {API key generated by FastGPT platform} | Complies with HTTP interface authentication standards to ensure the security of external system calls |
variables | Pass business fields such as section number, disposal date, and defect type | Injects business data into the document generation process, matching the field requirements of highway maintenance documents |
responseData | Extract generated document text, verification results, and associated data fields | Accurately obtains core business data returned by the interface, avoiding redundant information interfering with subsequent processing |
| Timeout period | 60-120 seconds | Document generation requires calling multi-source data; a longer timeout ensures complete data acquisition, adjust based on actual testing |
| Retry count | 2-3 times | Addresses short-term network fluctuations or temporary system response delays, ensuring the success rate of interface calls |
| Request body encoding | UTF-8 | Adapts to multi-language and special character transmission, avoiding garbled text issues |
Three common mistakes
- Phenomenon: After uploading XLSX format maintenance patrol logs, AI conversation cannot be triggered to generate documents. Cause: No adaptation rules for file parsing are configured, only plain text format interface input is supported, and no structured conversion is performed on table data.
- Phenomenon: Garbled text appears when calling the HTTP interface, including garbled text in web uploads, uploaded text files, and API uploaded strings. Cause: The encoding format of the request body and response body is not specified as UTF-8, resulting in parsing errors during multi-byte character transmission.
- Phenomenon: When the workflow cyclically calls the HTTP interface to generate batch maintenance work orders, interface call limit exceeded or timeout occurs. Cause: Reasonable call intervals and retry thresholds are not set, and the concurrent call restrictions of external systems are not matched.
How to confirm the configuration is correct
- Call the test interface with simulated section numbers and patrol data, check whether the fields returned by
responseDatainclude the expected document content and verification results. - Upload a test XLSX maintenance log file, confirm that the interface can complete structured parsing and generate corresponding drafts, with no garbled text or missing fields.
- Start the workflow to cyclically call the interface 3-5 times, check that the response status code for each call is 200, with no timeout or error messages.
- Verify the authentication information of the
Authorizationparameter, confirm that the external system's data source interface can be accessed normally, with no permission errors.
