What This Category of Data Looks Like
Data for infrastructure construction declaration materials and case review primarily comes from project construction permit application documents, environmental impact assessment approval documents, progress review ledgers, completion acceptance case files, and similar sources. Data updates follow project milestones, with concentrated submissions during individual review phases. Documents are provided as a combined set of multiple attachments, including PDF construction drawings, Word-format declaration descriptions, Excel-format bills of quantities, and more. Core fields include unique project number, construction entity name, review amount, review date, and acceptance node identifier. Common units are ten thousand yuan, square meters, and calendar days.
Constraints on HTTP Interfaces and External Systems
The multi-attachment document structure requires interfaces to support parallel file uploads, to avoid triggering platform size limits due to excess attachments in a single request. The fixed format of core fields requires request bodies to strictly match the types and units of fields such as project number and review amount, to prevent data parsing errors. The concentrated phase-based update rhythm requires interfaces to support batch review requests, while configuring a reasonable timeout threshold to avoid transmission interruptions for large-volume drawing files. Differences in attachment formats require interfaces to adapt to parsing rules for common document types including PDF, Word, and Excel, to ensure normal content readability.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Maximum number of files per request | First 10 | Matches the typical number of attachments for a single infrastructure construction review, and complies with the request limit rules of FastGPT v4.17.0 |
| Request timeout | 600 seconds | Adapts to the transmission and parsing duration of large-volume construction drawings, avoiding mid-transmission platform timeout interruptions |
| File upload format restrictions | Support PDF, DOCX, XLSX | Covers the mainstream attachment formats of infrastructure construction declaration materials, ensuring all types of files can be properly parsed |
Authorization | Carry a Bearer token issued by the platform | Complies with the interface identity verification standards of FastGPT v4.17.0, ensuring request legitimacy |
variables | Pass fields such as project number and review amount | Matches the core identification fields of infrastructure construction declaration materials, facilitating accurate subsequent case archiving |
responseData | Verify the returned case ID and status code | Ensure that a review case is successfully generated after the interface is called, avoiding data loss |
Three Common Misconfigurations
- Symptom: An error indicating unsupported file upload is returned after calling the interface. Cause: Attempting to upload local files directly without passing the platform-hosted file ID via
variables. - Symptom: The review case associated data returned by the interface is empty. Cause: The knowledge base ID was not correctly configured in the request, so the case archiving rules for the corresponding project cannot be matched.
- Symptom: A timeout error is triggered when submitting more than 10 attachments in a batch. Cause: The request timeout was not adjusted to a duration suitable for large file transmission, leading to transmission interruption.
How to Confirm Proper Configuration
- Initiate a single file upload request, and check whether the file ID returned in
responseDataexists and conforms to the platform's format rules. - Pass preset
variablesfields, call the interface, and check whether the returned case information includes the passed project identification fields. - Adjust the request timeout to the recommended value, then initiate a batch attachment submission request, and confirm that the request is not interrupted prematurely.
- Verify the validity of the
Authorizationtoken, and check whether the interface returns a status code indicating successful identity verification.
