What the data for this category looks like
Marketing content data for general equipment primarily comes from product technical manuals, parameter specification sheets, scenario application case documents, and official marketing materials provided by partner financial institutions and manufacturers. Data updates are triggered on demand alongside new product launches, parameter adjustments, or financial marketing campaigns, with no fixed high-frequency cycle.
Document structure includes two categories: structured parameter tables and unstructured scenario descriptions. Structured fields include device model, rated power, external dimensions, and others, with corresponding units of none, kW, and mm respectively. Unstructured content mostly consists of long-text usage scenario introductions, with single document lengths varying widely.
What constraints do these characteristics impose on HTTP interfaces and external systems?
The coexistence of structured parameters and long text requires the interface to support both structured field parsing and long text segmented upload. Materials with no fixed high-frequency update cadence but large single-file volume require the interface to support resumable uploads and large-file chunked upload logic.
Fields with clearly attached units require the interface to verify unit consistency during parsing or upload, to avoid mismatches between parameter values and their associated units. Version iteration requirements also require the interface to support carrying version identifiers to distinguish different batches of marketing content, preventing confusion between old and new materials.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1500 MB | General equipment marketing materials are mostly multi-page PDFs, technical manuals, or CAD drawings, with single-file volumes typically falling within this range |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long document parsing requires sufficient time to avoid interruptions before parsing completes |
CHUNK_SIZE | 800–1200 characters | The semantic unit length of parameter descriptions and scenario copy for general equipment fits this segmentation, ensuring complete information after splitting |
API_RATE_LIMIT | 10 requests per minute | Balance interface call efficiency and system load when synchronizing marketing content in batches |
REQUIRE_FILE_VERSION | Configure version fields according to actual materials | General equipment marketing materials undergo version iterations, requiring version fields to be carried via the interface to distinguish different batches of content |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Issue: Files uploaded via the create file collection API have inconsistent segmentation results with files uploaded directly via the platform, with deviations in the content range of the returned
chunkfield. Cause: TheCHUNK_SIZEparameter was not specified correctly during API upload, or the request did not carry the file hash verification header, causing the system to use default segmentation rules for processing. - Issue: When sending consecutive requests via the chat API, subsequent requests must wait for the previous generation to complete, and real-time interruption of the current generation process is not possible. Cause: Streaming response configuration was not enabled, and the interface did not implement interruption logic for SSE streaming callbacks, causing requests to be processed in a serial queue.
- Issue: After configuring an HTTP external system endpoint, calling the interface fails to synchronize marketing content, returning a 502 status code. Cause: The authentication key or request header format for the external system was not configured correctly, causing the system to fail the endpoint verification.
How to confirm the configuration is correct
- Upload a single general equipment marketing material that meets the maximum volume limit, check the platform file list after uploading via API, and confirm that the file size matches the upload request.
- Initiate consecutive chat requests, test whether new requests can be sent during generation to trigger interruption, and verify that the streaming response configuration is effective.
- Compare the segmentation results of the same file uploaded via API and directly via the platform, and confirm that the number of
chunks and content ranges are consistent. - Check the system logs, confirm that the status codes for open API calls are all 200, with no timeout or rate limit errors.
