HTTP Interface and External Systems for Registration and

Data Characteristics in this Category

Biopharmaceutical registration and declaration data typically originates from official databases of regulatory bodies (e.g., NMPA, FDA, EMA), internal enterprise Clinical Trial Management Systems (CTMS), and pharmacovigilance systems. Data update frequencies vary. Official databases might release approvals and review reports quarterly or annually, while internal enterprise data updates in real-time. Document structures are primarily structured and semi-structured, such as drug labels, Clinical Study Reports (CSRs), and Adverse Event Reports (ADRs). Common formats include PDF, Word, XML, and JSON. Fields cover drug name, active ingredient, indications, dosage and administration, adverse reactions, manufacturer, approval number, and registration status. Units strictly adhere to international standards, such as dosage units (mg, g) and concentration units (mol/L, %).

Constraints from these Characteristics on "HTTP Interface and External Systems"

The diversity and update frequency of registration and declaration data require HTTP interfaces to support integration with multiple data sources. Batch and periodic data imports from official databases necessitate efficient data synchronization capabilities and the ability to handle large files. Real-time requirements from internal enterprise systems demand event-driven data push support. The semi-structured nature of documents challenges data parsing capabilities, requiring extraction of key fields from unstructured documents like PDFs and Word files. The strictness of fields and standardization of units require interfaces to maintain data integrity and accuracy during data transmission and storage, preventing data errors due to unit mismatches. Furthermore, registration and declaration data often contain sensitive information, imposing high requirements on interface security and compliance, including support for encrypted transmission and authentication.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`maxConcurrentRequests`	`10`	Balances system load and real-time needs for periodic batch data imports
`requestTimeoutSeconds`	`600 seconds`	Accommodates time-consuming large file uploads and complex data processing
`dataChunkSizeKB`	`512 KB`	Optimizes large file transfer efficiency and reduces network overhead
`authMechanism`	`OAuth2`	Ensures secure access to sensitive registration and declaration data
`retryAttempts`	`3`	Addresses network fluctuations or temporary unavailability of external systems
`documentParsingEngine`	`PDFBox`	Specifically handles PDF document parsing common in the biopharmaceutical domain

Common Pitfalls

HTTP status code returns a 500 error, but no clear exception appears in the logs. This might be due to the external system timing out while processing the request, failing to return a result within the FastGPT-configured timeout, or an unhandled exception occurring within the external system.
The drug approval number field is empty in knowledge base retrieval results. This occurs when the document parsing engine fails to correctly identify and extract the approvalNumber field from non-standard formatted registration and declaration documents.
Some data entries are missing during batch import of registration and declaration data. This happens if the maxConcurrentRequests parameter is set too high, leading to external system overload, inability to process all concurrent requests, or refusal of some requests due to insufficient resources.

Verification of Configuration

Simulate requests to check if the HTTP interface returns a 200 or 201 status code and verify if the response body contains the expected dataId parameter.
Upload a complete registration and declaration PDF document and observe the parsing results in the knowledge base. Confirm that key fields like approvalNumber and activeIngredient are correctly extracted and populated.
Execute a batch data import test with 10 concurrent requests. Confirm all requests are processed successfully with no data loss. Check external system logs for any overload warnings.
In the integration testing environment, verify that interface calls using the OAuth2 authorization mechanism successfully retrieve and update registration and declaration data, and that unauthorized access is denied.
