What the data for this category looks like
The data for coal chemical industry declaration materials and file review mainly comes from enterprise production ledgers, environmental impact assessment approval archives, safety acceptance documents, and monthly capacity reports. Data update frequency follows declaration cycles: monthly regular declarations are updated each month, and major project files are updated on demand after project approval. A single declaration document includes fields such as project number, coal type category, capacity scale, pollutant emission indicators, and approval node records. Units include tons, cubic meters, and milligrams per cubic meter. Some files include structured Excel attachments and PDF scanned documents.
What constraints these characteristics impose on HTTP interfaces and external systems
The data characteristics of coal chemical industry declaration materials and file review create multiple constraints for HTTP interfaces. Mixed-format data from multiple sources requires interfaces to support input formats including PDF and Excel, with built-in basic format validation logic. Periodic update rhythms require interfaces to support both scheduled calls and manual trigger modes, adapting to monthly regular declaration and temporary project file scenarios. Specific fields and units require interfaces to perform unit validation for capacity and pollutant indicator fields, preventing input of values that do not follow coal chemical industry specifications. Large-volume file attachments require interfaces to support chunked uploads to avoid single-request timeouts.
How to Configure Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Authentication Method | Authorization header carrying Bearer token | Complies with general security specifications for industrial system interfaces, and adapts to internal permission control requirements of state-owned and public enterprises |
| Request Timeout | 600 seconds | Coal chemical industry files have large volume, and regular declaration material analysis requires extended processing time |
| Response Data Format | JSON | Facilitates external systems to parse declaration results and audit status fields |
| Variable Mapping Rule | Bind project number and coal type as fixed input parameters | Matches core identification fields of coal chemical industry declaration materials, reducing repeated data entry |
| Retry Trigger Condition | Response status code 5xx and retry interval no more than 30 seconds | Adapts to occasional fluctuations in external systems, avoiding frequent retries that increase server load |
| Maximum Retry Times | 3 | Balances interface stability and resource consumption, complies with operation and maintenance specifications of state-owned and public enterprise systems |
Three Common Misconfigurations
- The symptom is the interface returns status code 400, with an error message containing "invalid field format". The cause is failure to perform unit validation for capacity and pollutant indicator fields in coal chemical industry declaration materials, with non-compliant numerical units submitted.
- The symptom is a timeout error triggered after a single interface call exceeds the preset duration threshold. The cause is an overly short request timeout setting, which does not adapt to the analysis time required for large-volume coal chemical industry files.
- The symptom is that the
responseDatafield received by the external system is empty. The cause is incorrect configuration of the response data extraction rule, with no core business fields for audit results associated.
How to Confirm the Configuration is Correct
- Submit standard declaration material test data that complies with coal chemical industry specifications. Use the FastGPT v4.17.0 interface debugging tool to complete the authentication link test, and confirm there are no permission-related errors.
- View the interface response log, check the
responseDatafield, and confirm it includes core business fields such as declaration number and audit status. - Simulate occasional exceptions in the external system, trigger the interface retry logic, and verify that retry times and intervals match the preset configuration.
- Upload a single large-volume file attachment, confirm the interface supports chunked uploads, and no file format or size restriction errors occur.
