What data for this category looks like
Professional defense industry market aggregation interfaces and publicly available equipment industry monitoring data provide data for this category. Daily data updates run after daily market close. Weekly rolling cycle return data is updated weekly. Data documents use standard JSON format. Each data entry includes these fields: equipment model code, statistical date, daily return change value, cumulative return change value, and affiliated manufacturer identifier. All return change value fields are numeric. The statistical date field uses a YYYY-MM-DD formatted string.
What constraints these characteristics impose on HTTP interfaces and external systems
The data source’s professionalism requires interface requests to include a dedicated authentication credential. Valid data cannot be retrieved without this credential. The fixed update schedule after daily market close requires external system synchronization tasks to match this frequency. High-frequency calls will trigger interface rate limits. The fixed JSON field structure requires external systems to predefine strict field parsing rules. General financial data parsing logic cannot be reused directly. Non-standard field units and identifiers require external systems to configure dedicated field mapping and unit conversion rules. This avoids confusion with data from other categories. The uniqueness of equipment model codes requires the interface to return deduplicated data. Otherwise, external systems will display duplicate data entries.
How to set configurations
| Configuration Item | Recommended Value | Rationale for This Value |
|---|---|---|
API_REQUEST_TIMEOUT | 30 seconds | The response delay of the ordnance and equipment data source interface typically falls within the 10-25 second range. 30 seconds covers normal response durations and avoids long-term blocking of task queues |
RETRY_TIMES | 3 times | Military industry data source interfaces may experience temporary rate limiting. 3 retries cover most temporary failure scenarios and reduce the probability of data synchronization failures |
DATA_PARSE_SCHEMA | Map fields to equipment model code, statistical date, daily return change value, cumulative return change value, and affiliated manufacturer identifier | The fixed JSON structure of ordnance and equipment data requires strict matching of field names to avoid issues with empty field parsing |
REQUEST_AUTH_TYPE | Bearer Token | Professional data sources in the military industry generally use Bearer Token as the interface authentication method, which meets the security verification requirements of data interfaces |
BATCH_REQUEST_SIZE | 20 items per request | The single-batch data volume of ordnance and equipment data is moderate. 20 items balances request efficiency and interface rate limit restrictions, and avoids being blocked due to overly large single-request data volume |
EXTERNAL_SYNC_CRON | 16:30 daily | Domestic military-related data interfaces typically complete updates within 1.5 hours after market close. 16:30 covers normal update delays and ensures access to the latest daily data |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. Testing on local samples is recommended before finalizing settings.
Three common mistakes
- Symptom: A configured HTTP interface call returns a
401 Unauthorizedstatus code, with no valid data returned. Cause:REQUEST_AUTH_TYPEand the corresponding authentication token are not configured correctly. The military data source’s interface security check has not been passed. - Symptom: A custom data synchronization script runs with a path error prompt, and cannot load the interface configuration file. Cause: The actual path of the
LOCAL_FILE_PATHparameter is not filled in correctly. The path format does not meet system requirements. - Symptom: Duplicate equipment model data appears after a scheduled synchronization task runs, or some data field parsing returns empty. Cause: Complete field mapping rules are not configured in
DATA_PARSE_SCHEMA, or equipment model deduplication logic is not added. This leads to abnormal data parsing.
How to confirm correct configuration
- Manually trigger an HTTP interface call. Verify that the returned raw data includes preset core fields such as equipment model code and statistical date.
- Review the execution logs of the scheduled synchronization task. Confirm that no records of error status codes such as
401or504are present. - Compare the number of ordnance and equipment data entries displayed in the external system with the total number of entries returned by the interface. Confirm that no data is missing or duplicated.
- Validate the display format of return change values. Confirm that preset unit mapping rules have been applied correctly.
