HTTP Interface and External Systems for Batch Record Review

Batch Record Data Characteristics

Batch record data originates from Manufacturing Execution Systems (MES) and Quality Management Systems (QMS). This data primarily consists of structured and semi-structured documents. Updates typically occur immediately or daily after batch production completes. Document structures include production date, batch number, product name, equipment ID, operator information, material batch, inspection results, and deviation event records. Fields often contain numerous codes, enumerated values, and free-text descriptions. Examples include equipment EQP_ID, material MAT_BATCH_NO, and detailed Deviation_Description. Units vary, covering production volume (e.g., kg, L), time (e.g., min, h), and measurement (e.g., pH, °C). Units can differ across production stages.

Constraints from HTTP Interface and External Systems

Diverse batch record data sources require flexible HTTP interfaces to adapt to various upstream API specifications, including RESTful or SOAP. The update frequency dictates data synchronization strategies, necessitating support for periodic polling or event-driven push mechanisms to ensure data timeliness. The interface must map or transform codes and enumerated values during data transmission for FastGPT to correctly interpret them. Free-text descriptions like Deviation_Description demand robust model comprehension, requiring complete text transmission without truncation. Varied units and data types require accurate identification during data parsing to prevent type errors or unit confusion, which directly impacts knowledge base quality and retrieval accuracy.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`HTTP_METHOD`	`POST` or `GET`	Based on upstream API definition. `POST` is suitable for data push, `GET` for data pull.
`API_ENDPOINT_URL`	e.g., `/api/v1/batch_records`	Specific API path for batch record data ensures requests reach the correct resource.
`REQUEST_TIMEOUT_SECONDS`	`600` seconds	Batch record data can be large; this allows sufficient response time to prevent timeouts.
`MAX_RETRIES`	`3`	Handles network fluctuations or transient upstream system failures, improving data acquisition stability.
`DATA_PULL_CRON_EXPRESSION`	`0 0 2 * * ?` (2 AM daily)	Matches the daily update rhythm of batch records for scheduled data synchronization.
`CONTENT_TYPE`	`application/json` or `application/xml`	Based on the data format supported by the upstream API, ensuring correct request body parsing.

Common Pitfalls

Interface requests return a 400 Bad Request status code or missing data fields. This often occurs when field names, data types, or required parameters in the request body do not conform to the upstream API specification, leading to data validation failures.
Imported batch record content in the knowledge base is incomplete, with critical information like Deviation_Description truncated. This typically results from the interface response body size exceeding FastGPT's internal MAX_RESPONSE_SIZE limit or improper data segmentation.
Data synchronization tasks frequently fail, with Connection timed out errors in logs. This usually indicates that REQUEST_TIMEOUT_SECONDS is set too short for large batch record data volumes or high network latency.

Verification Steps

On the FastGPT interface configuration page, click the "Test Connection" button. Observe for a 200 OK status code and the expected data structure to verify interface connectivity.
Manually trigger a data synchronization task. Check the FastGPT knowledge base for newly added batch record documents. Randomly select a few to verify the completeness of critical fields like Deviation_Description.
Monitor background logs for data synchronization task execution status. Confirm no Connection timed out or Failed to parse response errors appear. Record the duration of each task to evaluate if REQUEST_TIMEOUT_SECONDS is appropriate.
