HTTP Interface and External Systems for Health Management

Data Characteristics in This Category

Health management quality documents typically include service agreements, health assessment reports, intervention plans, follow-up records, and outcome evaluations. Data sources are diverse, encompassing user-completed questionnaires, wearable device data, medical institution examination results, and scanned handwritten doctor's notes. Update frequencies vary; health assessments might be annual, while follow-up records update weekly or monthly based on intervention frequency. Document structures often feature standardized reports in PDF format, containing structured fields like blood pressure, blood sugar, and heart rate, alongside unstructured doctor's diagnostic advice. Self-completed questionnaires may store data in JSON or XML formats. Unit conversion is necessary, for example, between mmol/L and mg/dL.

Constraints Imposed by These Characteristics on "HTTP Interface and External Systems"

The diverse data sources for health management documents require HTTP interfaces to handle various data formats, including structured JSON, XML, and unstructured PDF documents. Since some data (e.g., examination reports) have a low update frequency but a large single data volume, interface design must consider the stability and efficiency of large file transfers. Extracting key information from unstructured documents demands robust data parsing capabilities from external systems. For instance, accurately identifying fields like blood pressure and blood sugar and their values from PDF reports, then standardizing units. High-concurrency scenarios are less common, but data consistency and accuracy requirements are stringent, especially when associating with user health records, necessitating strict data validation mechanisms.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`maxChunkSize`	800–1200 characters	Balances semantic completeness with model processing efficiency, avoiding overly long or short text blocks.
`PARSE_FILE_TIMEOUT_SECONDS`	600 seconds	Accommodates parsing large PDF documents, especially those with complex charts or scanned content.
`similarityThreshold`	0.78–0.85	Ensures retrieved health management documents are highly relevant to the query intent, reducing irrelevant information.
`extractStrategy`	Rule-based and semantic combination	Addresses the coexistence of structured and unstructured information in health management documents.
`retrievalCount`	Top 5–8 items	Ensures retrieval of sufficient relevant document fragments, providing rich context for the model.
`externalApiTimeout`	180 seconds	Accounts for the response times of external health data platforms, preventing data acquisition failures due to timeouts.

Common Pitfalls

When testing multimodal Embedding models, a {"error":{"code":"Invalid error often indicates that the Content-Type in the request body is not correctly set to application/json or the image encoding format does not meet API requirements.
When calling external interfaces to retrieve data, if images fail to display, the FastGPT-returned image URL might lack necessary authentication parameters or the image server might have anti-leeching protection configured.
When calling the v2/parse/file interface to parse PDF reports, if the returned result is empty or incomplete, it is often due to an outdated pdf-marker version, which cannot correctly process certain new PDF features or specific font encodings.

Verification Steps

Upload various formats of health management documents (PDF, JSON, XML) for testing and confirm that content is correctly parsed and segmented.
Simulate high-frequency external system data synchronization requests, observe interface response times and success rates, and ensure data updates complete within expected durations.
Randomly select different types of health management queries to verify that the model retrieves highly relevant document fragments and that key values and recommendations are accurate.
