Ledger Summary and Report Generation for Construction Project Environmental Impact Assessment Approval: HTTP Interfaces and External Systems

Ledger Summary and Report Generation for Construction Project Environmental Impact Assessment Approval: HTTP Interfaces and External Systems

What this category of data looks like

The data for this category primarily comes from the national unified construction project environmental impact assessment declaration and approval system, the ecological environment zoning control achievement database, the pollution discharge permit platform, and environmental monitoring data. Daily processed documents include environmental impact assessment reports or report forms, approval application materials, public participation explanations, technical evaluation opinions, and environmental impact assessment approval documents. Data updates do not follow a fixed cycle, and are synchronized with project declaration and approval progress. Data fields include project name, approval document number, construction unit, environmental impact assessment category, pollution control measure list, and more. There are no uniform mandatory units, and some fields must match the format requirements of the corresponding connected systems. The data in this link focuses on the pre-commissioning approval process for construction projects, and its application scenarios differ from pollution discharge permit data.

Data sources for this category are scattered, requiring integration with multiple external systems. As a result, HTTP interfaces must be compatible with the authentication rules of different systems, and the corresponding format of the Authorization parameter must be clearly defined. Data updates do not follow a fixed cycle, so interfaces must support on-demand triggering of data pulling. Daily documents include long-text reports and structured approval materials, so request bodies must adapt to both structured fields and file upload scenarios. There are no uniform mandatory units for fields, so interfaces must add format verification logic to avoid data abnormalities caused by unit mismatches. Errors in the approval process have serious consequences, so interfaces must be configured with timeout and retry mechanisms to ensure data transmission stability.

How to set configurations

Reference only; verify against the target FastGPT release and deployment documentation.

Configuration ItemRecommended SettingRationale for This Setting
AuthorizationBearer ${system preset key}Unified authentication format when connecting to multiple external environmental impact assessment-related systems
Request timeout period600 secondsEnvironmental impact assessment approval processes involve interactions across multiple systems, avoiding short timeouts that interrupt data pulling
responseDataStructured data grouped by project ID and approval statusAdapt to the aggregation requirements of ledger summary, simplifying subsequent report generation logic
File upload size limit1000 MBAdapt to the upload scenario of large documents such as environmental impact assessment reports
Number of failed retries3 timesEnsure data transmission stability during network fluctuations
variablesVariable set containing project ID and approval statusAdapt to the requirement of dynamically passing parameters in workflows

Three common errors

  • Symptom: The interface call returns an uncaught exception, and the page shows a failure after loading. Cause: The key format or path configuration of the Authorization parameter in the configuration file is incorrect during private deployment.
  • Symptom: When using the Safari browser to send a file upload request, the interface returns a format error or no response. Cause: Safari’s encoding rules for form-data type requests differ from other browsers, and corresponding compatibility handling was not implemented.
  • Symptom: When configuring form-data parameters in a workflow, file type fields cannot be passed correctly. Cause: The file parameter type was not set to the file upload format, and only text content was filled in.

How to confirm the configuration is correct

  • Call the test interface to check whether the fields returned in responseData include core ledger fields such as project ID and approval document number.
  • Upload a small environmental impact assessment document to confirm that the file upload request can be completed normally and return a valid response.
  • Simulate a network fluctuation scenario to check whether the interface triggers the retry mechanism and returns data normally after recovery.
  • Verify that the configured Authorization parameter matches the authentication requirements of the connected system.
