What the data for this category looks like
Feed-related data primarily comes from farm feeding logs, feed manufacturer formula systems, and dealer inventory ledgers. There are three update frequencies: feeding logs are reported in real time, inventory data is synced daily, and formula data is updated on demand. Documents use structured formats. Each data entry includes a unique feed identifier, applicable livestock and poultry type, raw material composition, shelf life, recommended feeding amount, and supply unit price. The units for these fields are string, enumeration value, kilogram/ton, day, kilogram/head, and yuan/ton respectively. There are no redundant nested fields.
What constraints this category's characteristics impose on HTTP interfaces and external systems
The multi-source data characteristics of the feed category impose multiple constraints on the HTTP interface and external system workflow. The high-frequency reporting requirement for real-time feeding logs requires the interface configuration to adapt to short connection timeout thresholds. Fixed-structure formula data does not need frequent pulling, requiring cache expiration durations matched to the update rhythm. Fields include enumeration values and multi-unit numerical values, requiring input parameter validation rules tied to the format requirements of corresponding fields. The requirement for syncing bulk inventory data requires the interface to support chunked upload to adapt to large packet transmissions.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
API_KEY | Exclusive key bound to external inventory or formula systems | Prevent unauthorized access to sensitive data related to feed production and sales |
REQUEST_TIMEOUT | 30 seconds | Match the average response duration for pulling feed formula data and reporting feeding logs |
UPLOAD_CHUNK_SIZE | 800–1200 kilobytes | Adapt to the packet size for bulk inventory data sync, avoid exceeding single upload limits |
CHAT_ID_PERSIST | Enabled (new in V4.9.7 and above) | Retain user interaction logs for feed marketing content to facilitate subsequent issue attribution |
API_RATE_LIMIT | Calibrated per business concurrency requirements | Match high-concurrency scenarios for frequent feeding log reports, avoid triggering interface rate limits |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapt to the parsing duration of feed formula documents, avoid timeout for long document parsing |
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, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: The interface returns
{"code":514,"statusText":"unAuthApiKey","message":"common:code_error.e"}. Cause: TheAPI_KEYparameter is not configured correctly, or the key does not match the bound external system. - Symptom: The incoming
chatIdfield is not displayed in the conversation log, and the user field in the log is empty. Cause: TheCHAT_ID_PERSISTconfiguration item is not enabled, or thechatIdparameter is not correctly included in the input parameters. - Symptom: Empty results are returned when retrieving chunked index content. Cause: The
UPLOAD_CHUNK_SIZEparameter is not configured correctly, causing the packet chunks to exceed limits and fail to be recognized by the interface.
How to confirm the configuration is correct
- Call the test interface with a valid
API_KEY, check that the return status code is 200 to confirm the authentication configuration is effective. - Submit a test request that includes the
chatIdfield, check whether the conversation log correctly records this field to confirm theCHAT_ID_PERSISTconfiguration is correct. - Upload bulk test feed inventory data, check whether the interface receives requests in chunks to confirm the
UPLOAD_CHUNK_SIZEconfiguration matches the current packet size. - Send high-frequency test requests, check that the interface does not trigger rate limits to confirm the
API_RATE_LIMITconfiguration matches business concurrency requirements.
