HTTP Interface and External Systems for an Internal Office

Data Characteristics

Data for OA process initiation in the biopharmaceutical sector originates from employee actions within internal systems. Examples include leave requests, expense reports, project applications, and procurement approvals. Data updates are infrequent, typically generated when an employee submits an application, with status changes occurring during the approval process. Document structures are often structured or semi-structured, containing fields such as initiator, application type, content, amount, date, and approval history. Field units are clearly defined; for instance, amounts are in "RMB" or "USD," durations in "days" or "hours," and drug quantities in "boxes" or "units." This data is usually stored in internal relational databases or specific OA systems, exposed via API interfaces.

Constraints Imposed by "HTTP Interface and External Systems"

The low update frequency of OA process initiation implies relaxed real-time requirements, but data accuracy and completeness are critical. Structured data facilitates clear field mapping in interface design, reducing parsing complexity. For example, the amount field in an expense report process requires strict validation of numerical type and unit. Approval history, as semi-structured data, may require more flexible data structures (e.g., JSON arrays) to accommodate approval comments and operators at different stages. Due to sensitive internal operations, interface security requirements are high, necessitating robust authentication and authorization mechanisms. The single source of data (typically a specific OA system API) dictates reliance on specific interface protocols and data formats.

Configuration Guidelines

Configuration Item	Suggested Value	Rationale
`timeout_seconds`	`60 seconds`	OA process initiation typically involves small data transfers and simple business logic processing. 60 seconds is sufficient, preventing unnecessary timeouts due to network fluctuations or transient backend load.
`max_retries`	`3 times`	Considering transient network instability or temporary backend service unavailability, a retry mechanism improves success rates. 3 retries can recover in most situations.
`request_method`	`POST` or `PUT`	OA process initiation involves creating or updating resources. `POST` should be used to create new processes, and `PUT` to update existing process statuses, adhering to RESTful principles.
`content_type`	`application/json`	Biopharmaceutical OA process data is often structured. JSON format facilitates data transfer and parsing and offers good compatibility.
`auth_header_name`	`Authorization`	A standard authentication header field used to transmit credentials like API Keys or JWT Tokens, ensuring interface security.

Common Pitfalls

HTTP 504 Gateway Timeout errors when calling interfaces. This typically indicates the backend service processing time exceeded the timeout_seconds setting of a proxy server or FastGPT itself.
Interface calls succeed, but the process status does not change. This might be due to missing or incorrectly formatted mandatory fields in the request body, preventing the backend system from correctly parsing and executing business logic.
Database queries return empty results, even if the SQL statement executes correctly in other tools. This could relate to database connection pool configuration, permission issues, or differences in FastGPT's SQL execution context.

Verification Steps

Use FastGPT's debugging interface to observe if the HTTP request's HTTP Status Code is 200 or 201.
Verify within the OA system that the corresponding process has been successfully initiated or its status updated as expected.
Check FastGPT's operational logs for timeout_seconds-related error messages or business error codes returned by the interface.
