What this category of data looks like
Data sources include grain reserve warehouse management systems, central reserve grain management platforms, and internal inbound and outbound account books. Update schedule follows three cycles: real-time synchronization of inbound and outbound operation data, daily update of daily total inventory, monthly update of monthly rotation execution plans, and quarterly update of storage quality inspection files. Each structured record contains these fields: grain variety, storage bin number, current inventory quantity, inbound batch number, quality inspection qualification flag, storage environment temperature, storage environment humidity. Inventory quantity is measured in tons, temperature in degrees Celsius, and humidity in grams per cubic meter.
What constraints these characteristics impose on HTTP interfaces and external systems
The real-time and structured nature of grain reserve data creates multiple constraints for HTTP interfaces. Real-time inbound and outbound data requires interfaces to support high-frequency pulling or event callbacks, to sync the latest inventory changes. Daily updated total inventory requires interfaces to support batch data pulling by date range. Filter queries for structured fields such as grain variety and storage bin number require interfaces to support multi-condition combined parameters. Unified units for storage environment temperature and humidity require interfaces to preset parameter formats, to avoid cross-system unit conversion errors. Data compliance rules mandate that interface requests carry valid identity credentials, and that all transmission be encrypted.
How to set configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Carry an application-specific key prefixed with Bearer | Complies with FastGPT v4.17.0 interface identity verification rules, ensuring compliance with grain reserve data access requirements |
variables | Pass {"grain_type": "wheat", "storage_period": "monthly"} | Used to filter reserve data by grain variety and statistical cycle, matching structured query requirements |
responseData | Only return grain_type, stock_quantity, storage_location | Compresses returned content to reduce network transmission time, adapting to high-frequency query scenarios |
| Request timeout | 600 seconds | Addresses large data volume transmission needs when pulling quarterly quality inspection files in batches |
| Data pull limit | First 500 entries | Matches the reasonable data volume for a single interface request, avoiding timeouts caused by excessive data |
| Retry count | 3 times | Addresses call failures caused by network fluctuations or temporary interface jitter |
Three common errors
- An interface call returns the
401 Unauthorizedstatus code. The cause is failure to correctly carry theAuthorizationparameter, incorrect credential format, or failure to use an application-specific key for identity verification. - An interface request times out and returns
504 Gateway Timeout. The cause is an excessively short request timeout setting, which does not adapt to large data volume transmission requirements for batch pulling of reserve data. - The fields specified in
responseDatareturned by the interface are empty. The cause is a mismatch between the filter conditions and actual reserve data, or incorrect configuration of the return field rules.
How to confirm the configuration is complete
- Call the test interface, check that the returned HTTP status code is
200 OK, and confirm that the identity verification configuration is effective. - Compare the fields returned by the interface with the fields specified in the
responseDataconfiguration item, and confirm that the returned content matches expectations. - Pass preset filter parameters, check the match between the returned data and the local reserve account book, and confirm that the filter configuration is effective.
- Simulate high-frequency interface calls, check that the response time meets the preset timeout threshold, and confirm that the timeout configuration is reasonable.
