What the Data for This Category Looks Like
Document data for telecommunications engineering construction mainly comes from project management systems, design disclosure documents, site acceptance ledgers, and bidding archive files. Data updates are carried out according to project execution milestones. Updates are synchronized once a week within a single project cycle, and archived and locked after the project is completed. Documents are mainly in docx format, and some supporting lists are in xlsx format. Fixed fields include project number, engineering section, main material specification, engineering quantity, and acceptance conclusion. Units mostly use general engineering measurement standards such as meters, cubic meters, kilowatts, and sets.
What Constraints These Characteristics Impose on the HTTP Interfaces and External Systems Link
The mixed docx and xlsx format of telecommunications engineering construction documents requires HTTP interfaces to support pulling and parsing binary file streams. Interfaces that only support plain text cannot adapt to this scenario. Fixed engineering-specific fields and measurement units require that interface return data must strictly match preset field names and unit formats to avoid field mapping errors. The update rhythm based on project milestones requires interface calls to adjust frequency according to the project cycle to avoid occupying system resources from high-frequency calls. Multi-document associated project scenarios require interfaces to support the ability to batch pull associated documents.
How to Configure Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Approach | Basis for This Approach |
|---|---|---|
| Authorization | Carry a project-specific token in Bearer format, valid for 7200 seconds | Adapt to the permission hierarchy requirements of telecommunications engineering construction and ensure data access security |
| variables | Pass in two variables: projectid and materialtype, with a value range of 1-10000 | Accurately locate document data of the target project and narrow the interface return scope |
| responseData | Extract docx file streams and xlsx list fields, with a single return size not exceeding 1000 MB | Adapt to the feature of large document file volume for single projects and avoid transmission timeouts |
| Timeout | Set to 600 seconds | Address the transmission time consumption of large-volume engineering documents and avoid request interruptions |
| Request frequency limit | Adjust call frequency according to project milestones | Match the document rhythm updated by milestones and avoid triggering interface current limiting |
Three Common Misconfigurations
- A "format not supported" error is returned when calling the content interface, and the docx file can be downloaded normally when accessing the corresponding link via a browser. Cause: The interface is not configured with binary file stream parsing rules and only accepts plain text request bodies.
- A 500 status code is returned when calling the interface, and the model connection fails. Cause: The interface authorization configuration was not updated synchronously, and the old token does not match the new version's permission verification rules.
- Document data returned by the interface lacks engineering unit information and cannot be directly used for engineering quantity accounting. Cause: Variable requirements for corresponding fields were not passed in the request, and the measurement unit fields to be returned were not specified.
How to Verify Successful Configuration
- After calling the interface, check the returned file format and confirm that it can be normally parsed into a document file of the corresponding format, matching the structure of the project documents.
- View the fields returned by the interface and confirm that they include the preset engineering-specific fields, and that the units comply with telecommunications engineering measurement requirements.
- Simulate daily calling scenarios and confirm that the interface can stably return data without abnormal errors.
- Verify the validity of the authorization configuration and confirm that the document data of the target project can be normally obtained without permission interception prompts.
