What Data for This Category Looks Like
Financial report data for domestic civil airports comes from three sources: official annual and half-year financial reports publicly disclosed on airport group websites, listed airport financial reports on Shanghai, Shenzhen, and Hong Kong stock exchange disclosure platforms, and industry statistical operation data released by regional civil aviation administrations. Update schedules follow these rules: annual reports are released within four months after the end of the fiscal year, and monthly core operation data is updated before the 15th of the following month. Single financial report documents have a fixed structure, including modules for core operation indicators (passenger throughput, cargo and mail throughput, takeoff and landing sorties), financial details (revenue, operating costs, net profit), and non-operating profit and loss. Field names follow civil aviation industry statistical standards. Some disclosure documents have unit differences; for example, revenue may be denominated in yuan or ten thousand yuan.
What Constraints Do These Characteristics Impose on HTTP Interfaces and External Systems
Data sources are scattered, so three types of HTTP services must be connected: airport group official website APIs, exchange disclosure interfaces, and civil aviation industry statistical interfaces. Different interface authentication rules must be adapted to. Monthly operation data has a high update frequency, so short-cycle synchronization tasks must be configured. Annual financial reports only require quarterly verification and updates. Single financial report documents are lengthy. Some interfaces return paginated raw data, so pagination splicing logic must be handled. Some disclosure documents have unit differences. Unit verification and conversion logic must be added during the interface parsing stage to avoid data calculation errors.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
SYNC_DATA_INTERVAL | 86400 seconds (monthly data), 2592000 seconds (annual data) | Matches the update rhythm of aviation airport monthly and annual data, avoids unnecessary repeated requests |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Reserves sufficient time for parsing and field extraction, given the length of single financial report documents |
API_AUTH_TYPE | api_key (exchange interfaces), public (civil aviation administration public interfaces) | Adapts to authentication requirements of different data sources. Public data sources do not require authentication, while exchange interfaces require key configuration |
RESPONSE_PAGINATION_ENABLE | true | Adapts to the pagination return format of some interfaces, automatically splicing complete financial report data |
UNIT_CONVERSION_SWITCH | Enabled | Handles unit differences across different disclosure documents, uniformly converting data to standard units (yuan/passenger/ton) |
MAX_RETRY_TIMES | 3 times | Addresses temporary fluctuations in public interfaces, preventing synchronization tasks from being interrupted by a single failed request |
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 targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: External financial report interface calls return a
403 Forbiddenerror. Cause: TheAPI_AUTH_TYPEparameter for exchange disclosure interfaces is not correctly configured, and a public authentication method is used for interfaces that require a key. - Phenomenon: Synchronization tasks frequently time out, with
ETIMEDOUTerrors displayed in logs. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted based on the length of financial report documents, and the default timeout period is insufficient to complete long document parsing. - Phenomenon: Parsed data values are abnormally large or small. Cause: The
UNIT_CONVERSION_SWITCHis not enabled, and the unit difference between yuan and ten thousand yuan across different disclosure documents is not addressed.
How to Confirm Successful Configuration
- Call the test interface to obtain single airport financial report data, and check whether the units of the passenger throughput and cargo and mail throughput fields in the returned results are unified to standard units.
- View synchronization task logs, and confirm that authentication requests from multi-source interfaces all return a
200 OKstatus code, with no403or401errors. - Manually trigger a pagination interface test, and confirm that the returned complete data matches the original text disclosed by the exchange, with no data truncation.
- Configure a scheduled synchronization task, wait for a complete update cycle, and check whether the financial report data stored in the database has been updated to the latest version.
