What this category of data looks like
This category of data covers full-process documents and supervision data for pollution discharge permit management in the ecological environment sector. Sources include the national pollution discharge permit management information platform, enterprise environmental protection ledgers, online monitoring systems, and environmental statistics systems. Commonly involved documents include pollution discharge permit application forms, implementation reports, self-monitoring plans, ledger records, change applications, and permit copies.
Data updates occur quarterly. Each single data entry includes core fields such as permit limits, emission boundaries, and supervision requirements. Units follow legal metrology standards for emission concentration and emission volume. Service targets include pollution discharge permit management positions in ecological environment departments, environmental protection departments of polluting enterprises, and third-party environmental protection service institutions. Data use must comply with compliance requirements for ecological environment supervision.
Constraints for HTTP Interfaces and External Systems
Data sources for this category are scattered. Integration with HTTP interfaces from multiple external systems is required. Interface authentication and data format adaptation must meet the requirements of different systems.
The data update frequency is quarterly. Interfaces do not need high-frequency polling, but must support incremental pulling of the latest permit data on a quarterly basis.
Document types are diverse. Interfaces must support passing policy and business documents of different structures. They must also verify that fields comply with compliance formats for pollution discharge permits.
Core fields must strictly match industry technical specifications and permit limits. Interface return results must include accurate policy basis entries. No field missing or format errors are allowed.
How to configure settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Carry a Bearer token issued by the platform | When integrating with external systems such as the national pollution discharge permit management information platform, access permissions must be verified via authentication parameters |
| Interface timeout period | 300–600 seconds | Pulling pollution discharge permit data requires checking multiple ledgers and monitoring data, which takes a long time. A default short timeout will cause request interruptions |
variables | Pass ["pollution_license", "environmental_statistics"] | Differentiate pollution discharge permit data from different sources, adapting to multi-system integration scenarios |
| Number of documents queried per request | First 10 entries | When matching pollution discharge permit policy bases, avoid returning too many redundant entries that reduce query efficiency |
| Maximum file size | 1000 MB | Adapt to the upload requirements of large-volume documents such as pollution discharge permit implementation reports and self-monitoring plans |
responseData | Configure to return matching policy basis entries and corresponding document IDs | Ensure return results meet business query needs for pollution discharge permit management |
Three common configuration errors
- Interface requests return a 504 gateway timeout error, and logs show request duration exceeds 60 seconds. This occurs because the default timeout configuration is not adjusted. Pulling pollution discharge permit data requires checking multiple ledgers and monitoring data, and the default short timeout cannot cover the full request cycle.
- When calling an interface with multiple policy documents, the return result only matches the content of a single document. This occurs because multi-file parsing related settings are not correctly configured, and only the content of the first passed document is recognized.
- External systems return a 401 unauthorized error, and interface calls fail. This occurs because the
Authorizationparameter is not correctly filled, and no authentication token meeting the external system's requirements is carried.
How to verify correct configuration
- Call a test interface, pass test data for a pollution discharge permit copy, and check if
responseDatareturns matching policy basis entries and corresponding document IDs. - View interface logs to confirm that the request timeout period matches the configured 300–600 seconds.
- Test multi-file upload, pass two documents: a self-monitoring plan and a ledger record, and check if
variablescorrectly passes business identification parameters. - Integrate with the test interface of the national pollution discharge permit management information platform, verify that the
Authorizationparameter passes authentication and returns valid data.
