What this category's data looks like
The data for infrastructure construction project financing daily reports comes from the National Construction Market Regulation Public Service Platform, project financing filing announcements from local housing and urban-rural development departments, and credit loan ledgers from partner banks. Data is fully refreshed for the previous day every early morning.
Each data entry includes fixed fields: project unique identifier, project name, construction address, total investment amount, daily new financing amount, financing institution, fund arrival date, and fund purpose. Monetary fields use ten thousand RMB as the unified unit. Date fields follow the ISO 8601 standard format. The number of fields per entry is fixed, with no additional extended fields.
What constraints these characteristics impose on HTTP interfaces and external systems
The large scale of multi-source fully refreshed data requires interfaces to support incremental pull parameters, to avoid excessive bandwidth usage from single requests. Fixed field structure and unit requirements require external systems to configure field validation rules when connecting, to ensure received data formats and units meet business standards. The core usage scenario of filtering by date requires interfaces to support filtering by fund arrival date, to quickly locate project data for the target time period. The maximum single batch return data volume can reach hundreds of entries, requiring interfaces to support pagination parameters to prevent connection interruptions caused by overly large single request responses. The fixed project unique identifier field supports precise queries by project ID, meeting the needs of external systems to pull data for individual projects.
How to Configure
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
request_timeout | 300 seconds | The large volume of data returned in a single batch for infrastructure construction project financing daily reports means the standard 120-second timeout is insufficient for full data pulls. 300 seconds covers interface response times for most scenarios. |
pull_incremental | true | The large volume of daily fully updated data makes incremental pull reduce bandwidth usage between external systems and interfaces, only synchronizing newly added or updated data. |
query_filter_field | funding_date | Financing daily reports focus on daily data. Filtering by fund arrival date allows quick location of project data for the target time period, aligning with business usage habits. |
response_content_type | application/json | Most external systems support JSON format parsing, and the clear field structure facilitates mapping to databases or business objects in business systems. |
pagination_enabled | true | The maximum single batch return volume of project data can reach hundreds of entries. Enabling pagination prevents connection interruptions or timeouts caused by overly large single request responses. |
field_unit_validate | true | Financing amount fields are fixed to ten thousand RMB. Enabling validation prevents external systems from receiving data with non-standard units, reducing subsequent business processing errors. |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by data format, data volume and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing.
Three Common Configuration Mistakes
- Symptom: The interface returns a
400 Bad Requeststatus code, with the response body displayingno data provided. Cause: Thequery_filter_fieldparameter is not configured correctly, and no date range filter is specified, resulting in an empty dataset returned by the interface. - Symptom: Scheduled synchronization tasks frequently time out and interrupt. Cause: The
request_timeoutparameter is not set to a value appropriate for the data volume, and the default timeout duration is insufficient for single batch data pulls. - Symptom: Ongoing synchronization tasks cannot be terminated. Cause: No call logic for the corresponding termination interface is configured in the external system, and the task termination API parameters provided by the platform are not connected.
How to Confirm Configuration Is Complete
- Send a single interface request, check that the returned fields include core fields such as project unique identifier, financing amount, and date, and confirm that the field format matches the requirements of the business system.
- Configure a scheduled synchronization task, observe whether the volume of data pulled for the first time matches expectations, and adjust pagination parameters to adapt to the return scale of single requests.
- Simulate passing filter parameters with non-standard date formats, check whether the interface returns a corresponding error prompt, and confirm that the validation rules are in effect.
- Send a test request to terminate the task, confirm that the platform can normally interrupt the ongoing synchronization process, and verify the correctness of the termination interface configuration.
