What This Category of Data Looks Like
Data sources for crop farming yield rate data include agricultural product monitoring platforms under the Ministry of Agriculture and Rural Affairs, public interfaces from domestic agricultural product spot trading markets, and cost ledger data from agricultural input suppliers. Daily average purchase prices are updated after daily market close. Quarterly crop per-unit yield and planting cost accounting data is updated weekly. The document structure includes crop category identifiers, planting area codes, unit costs, average purchase prices, and yield calculation fields. Units include yuan per mu, kilograms per hectare, percentage, and others. Some fields require association with the start and end times of the current planting cycle.
Constraints for HTTP Interfaces and External Systems
The multi-dimensional classification and periodic update characteristics of crop farming yield rate data create clear requirements for HTTP interface parameter validation. The interface must support validation for three core parameters: crop category, planting area, and time range. This prevents invalid data calls across cycles or categories. Time-split data sources require the interface to support incremental pull configurations. This reduces resource consumption from full requests. Unit differences across crops (such as mu and hectare) require the interface to attach standard unit identifiers to returned fields. This prevents parsing errors in external systems. Public agricultural data sources have interface rate limits. A reasonable request interval parameter must be configured to avoid triggering access restrictions.
Configuration Settings
| Config Item | Recommended Value | Rationale |
|---|---|---|
API_KEY | Secret key bound to a dedicated project | Prevents key leaks from affecting calls across the entire platform |
REQUEST_TIMEOUT | 15-30 seconds | Matches response times of most public agricultural data interfaces |
MAX_RETRY_COUNT | 2 retries | Balances interface retry success rate and request load |
DATA_TIME_RANGE | Filter data from the current day to the previous day using trade_date | Matches the update schedule for crop farming yield rate daily reports |
UNITS_STANDARDIZATION | Enabled | Unifies unit formats such as yuan/mu and kg/hectare |
REQUEST_INTERVAL | 8-12 seconds | Matches rate limits of public agricultural data sources |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Calls return a 401 status code, but the same API key works in Postman. Cause: The
API_KEYconfigured in FastGPT is not bound to the access permission of the corresponding data source, or extra spaces are included when entering the key parameter. - Two duplicate requests are triggered, and the Authorization field of the second request is empty. Cause: The redirect logic of the external system does not correctly carry the authentication header, resulting in loss of key information in the second request.
- The interface returns an
unAuthChaterror. Cause: The domestic SaaS version of FastGPT V4.8.17 has not enabled the whitelist configuration for external interfaces, or the free tier quota has been exhausted.
How to Verify Successful Configuration
- Call the interface and check the unit format of the returned fields. Confirm that the format is unified to standard values, verifying that the
UNITS_STANDARDIZATIONconfiguration takes effect. - Send a test request and check the platform logs. Confirm that the request interval matches the configured
REQUEST_INTERVALparameter, with no rate limit prompts. - Call the interface with an invalid API key. Confirm that a 401 status code is returned, verifying that the key validation logic works correctly.
- Check the external interface call statistics. Confirm that the request success rate meets expectations.
