What this category of data looks like
This category of data is sourced from the national unified construction project environmental impact assessment (EIA) declaration and approval system, ecological environment zoning control results, pollution discharge permit platform, and environmental monitoring data. Daily generated documents include environmental impact assessment reports/statement forms, approval applications, public participation explanations, technical assessment opinions, EIA approval replies, and other documents. These documents contain core fields such as project category, EIA level, pollution prevention measures, and public participation content. Data updates follow no fixed cycle, and are synchronized with project declaration and approval progress.
What Constraints These Characteristics Impose on HTTP Interfaces and External Systems
The data sources for this category are scattered, document structures are complex, and field requirements are strict. This requires HTTP interfaces to support integration with multiple external systems and unified format conversion. Data updates follow no fixed cycle, so interfaces must support on-demand trigger call logic. Missing core fields will directly block approval processes, so interfaces must include built-in field integrity check rules. Interface call failures will disrupt approval material generation, so a reliable retry and abnormal alarm mechanism must be configured.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale for This Setting |
|---|---|---|
| Authorization | Bearer {external system API key} | When docking with the national unified construction project EIA declaration and approval system, official authentication keys must be used for identity verification |
| variables | {"project_code": "auto-sync", "pollution_measures": "pull from zoning control results"} | Automatically fill core business fields of EIA documents to reduce manual entry errors |
| responseData | Only return structured content of approval applications and public participation explanations | Filter redundant data and focus on core information required for EIA document drafting |
| Timeout Threshold | 600 seconds | Generating EIA documents requires pulling data from multiple external sources, single call takes a long time, avoid early interruption |
| Single Return Data Limit | Top 100 entries | External systems related to EIA have large data volumes, limiting return entries to avoid interface overload |
| File Upload Size Limit | 1000 MB | Adapt to the demand for large-capacity monitoring data attachments included in EIA documents |
Three Common Configuration Mistakes
- Scenario: A call to the national unified construction project EIA declaration and approval system interface returns a connection failure, with a status code of 502 or 403. Cause: Proxy parameters are not configured, or proxy settings are incorrect, preventing access to external systems through restricted networks.
- Scenario: Generated EIA approval application documents lack public participation explanation content. Cause: The variables field mapping rules are not configured correctly, and public participation data from external systems is not pulled.
- Scenario: An interface call returns a 401 status code, with no valid data obtained. Cause: The Authorization parameter is not set correctly, identity verification failed, causing the interface to refuse to return content.
How to Verify Proper Configuration
- Call the test interface, check if the returned responseData includes the core fields required for EIA documents. Adjust filtering rules until all necessary content is covered.
- Simulate basic project data to call the interface, verify that automatically filled fields via variables match project information from external systems, and correct mapping rules as needed.
- Simulate a restricted network environment, test whether proxy configurations take effect, and ensure normal access to external systems.
- Verify that the Authorization parameter format is correct, call the interface to confirm identity verification passes, and avoid returning a 401 status code.
