HTTP Interface and External Systems for Internal Policy

Data Characteristics

Policy retrieval in the biopharmaceutical sector relies on data from internal quality management system documents, SOPs (Standard Operating Procedures), GMP (Good Manufacturing Practice) documents, regulatory compliance reports, and R&D project management specifications. These documents typically exist as PDFs, Word files, or within internal knowledge bases. Data update frequency is relatively low, occurring primarily during regulatory policy adjustments, internal process optimizations, or new product development phases. Document structures are highly standardized, often including fields like title, chapter, version number, effective date, revision history, and attachments. Content involves specialized terminology and acronyms, such as "batch production record," "deviation management," and "QC release," requiring accurate semantic understanding.

Constraints Imposed by These Characteristics on HTTP Interfaces and External Systems

The standardized structure of policy documents requires HTTP interfaces to handle structured or semi-structured data. For example, specific chapters or metadata might be retrieved via API calls. Due to infrequent updates, real-time requirements for external system interfaces are relatively relaxed, but support for version control and historical queries is necessary. The extensive use of specialized terminology and acronyms in documents necessitates consistent encoding during HTTP transmission to prevent garbled text or semantic loss. Documents are typically stored on internal file servers or content management systems. Therefore, HTTP interfaces need appropriate authentication and authorization mechanisms to ensure data security and compliance. Document sizes can be large, requiring HTTP interfaces to support large file chunked uploads or downloads.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`HTTP_REQUEST_TIMEOUT`	`60 seconds`	Handles large policy document uploads and downloads, preventing timeouts due to network fluctuations.
`MAX_FILE_SIZE_MB`	`200 MB`	Accommodates common large PDF or Word documents in the biopharmaceutical sector.
`CHUNK_SIZE_BYTES`	`1048576 bytes`	Optimizes large file transfer efficiency, reducing single request load.
`AUTH_HEADER_NAME`	`Authorization`	Conforms to industry-standard authentication mechanisms, such as Bearer Token.
`RETRY_ATTEMPTS`	`3 times`	Addresses transient network instability, ensuring reliable policy data transmission.
`RESPONSE_CONTENT_TYPE`	`application/json`	Standardizes interface response format for easier parsing and processing of structured data.

Common Pitfalls

HTTP requests return 401 Unauthorized or 403 Forbidden status codes. This occurs when authentication information (e.g., the Token in the Authorization header) is not correctly passed or has expired, leading to external system access denial.
Document content returned by the interface appears garbled or some characters are unrecognizable. This happens when the external system's data encoding does not match the encoding expected by FastGPT; for example, the external system uses GBK while FastGPT defaults to UTF-8.
Uploading large policy documents results in a 504 Gateway Timeout. This typically occurs when the HTTP_REQUEST_TIMEOUT parameter in the HTTP module is set too short, failing to cover the entire time required for large file transfer.

Verification Steps

Initiate a request to the external system's policy retrieval interface via FastGPT's HTTP module. Check if the response status code is 200 OK.
Configure a simple query in FastGPT to simulate a user's policy content retrieval. Verify that the returned document content matches the original, especially for specialized terminology and acronyms.
Upload a typical, medium-sized policy document. Observe if the HTTP request response time completes within the HTTP_REQUEST_TIMEOUT threshold.
Attempt to retrieve a policy document containing multiple languages or special characters. Confirm that the results show no garbled text.
