What the data for this category looks like
Data sources for industrial park intelligent due diligence reports include industrial park operation management systems, real estate registration platforms, settled enterprises’ industrial and commercial public disclosure systems, energy consumption monitoring platforms, and rent collection ledgers. Settled enterprise information updates in real time alongside investment promotion progress. Energy consumption data updates hourly or daily. Rent ledgers update monthly. Park plan changes update quarterly. Document structure includes the park basic information module, settled enterprise list module, energy consumption and cost module, and surrounding supporting facilities module. Fields include total land area, floor area ratio, unified social credit code of enterprises, monthly electricity consumption, rent unit price, and others. Corresponding units are square meters, no unit, no unit, kilowatt-hour, yuan per square meter per month, respectively.
Constraints Imposed on HTTP Interfaces and External Systems
Multiple data sources require integration with multiple external systems. Each system may use different authentication methods and request formats, so interface parameters must be configured separately. Data with varying update frequencies needs matching polling intervals. This prevents excessive API calls or data lag. The long document and multi-field structure requires interfaces to support large file uploads and complex metadata transfer. Strict validation of field formats and units is required to prevent data entry errors. Multi-dimensional filtering requirements mean interfaces must support flexible metadata filtering configurations. This ensures retrieved due diligence data aligns with business scenarios.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Industrial park due diligence reports contain multi-source integrated long documents. Parsing typically takes a long time. The default timeout is insufficient for complete parsing. |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Park due diligence reports may include high-definition architectural drawings and multiple batches of settled enterprise data files. Single file size is generally larger than in general scenarios. |
external_api_auth_type | Multi-authentication mixed configuration | Connected external systems use different authentication methods, such as API keys and OAuth2. Configuration must support assigning corresponding authentication rules to different interfaces. |
dataset_metadata_filter_fields | Park ID, unified social credit code of settled enterprises, energy consumption statistics cycle | Industrial park due diligence requires filtering data by specific dimensions to avoid irrelevant park or enterprise information being included in the knowledge base. |
api_request_interval | 30–60 seconds | Energy consumption data updates hourly. Too short a polling interval will consume system resources. Too long an interval will fail to capture real-time data. |
api_response_max_retries | 3 times | External interfaces may experience temporary failures due to network fluctuations. Setting a reasonable number of retries improves call success rates. |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Errors
- Calling the
/api/core/dataset/collection/create/localFileendpoint returns a 404 status code. This occurs when public API exposure permissions for local file uploads are not enabled in the system settings of version 4.9.1, or when an outdated interface path is used. - After configuring metadata filtering, retrieved results are not filtered by the specified dimension. This happens when filter fields are not correctly added to the
dataset_metadata_filter_fieldsconfiguration item, or when field names do not match those returned by the external interface. - The long document parsing interface returns a 504 timeout status code. This is caused by failing to adjust the
PARSE_FILE_TIMEOUT_SECONDSconfiguration, using the default short timeout value that cannot cover the full parsing duration of industrial park due diligence reports.
How to Verify Configurations Are Correct
- Write a lightweight test script to call the configured external interface, verifying that authentication parameters, request paths, and return formats match configuration requirements.
- Upload a standard industrial park due diligence report, checking if the parsed metadata includes the configured filter fields.
- View system operation logs, confirming that API request intervals and timeout values match preset configurations, with no frequent connection failure errors.
- Initiate a workflow call, verifying that the interface can normally trigger data pulling from external systems and complete subsequent processing.
