What Data for This Category Looks Like
Data for this category comes primarily from public documents of domestic refractory material industry associations, disclosure reports from upstream raw material enterprises, procurement requirement descriptions from downstream steel and building material enterprises, and organized content from professional building material information platforms. Update frequencies fall into three categories: quarterly industry white papers, monthly market updates, and daily market briefings. Single documents have a fixed structure including modules such as raw material cost data, production capacity scale, downstream application scenarios, and policy compliance requirements. Fields include raw material unit price (unit: yuan/ton), monthly output (unit: thousand tons), number of cooperating enterprises, and more. Document length varies widely, with some in-depth analysis content being relatively long.
What Constraints These Characteristics Impose on HTTP Interfaces and External Systems
The multi-source, scattered origins of refractory material research reports require HTTP interfaces to support multi-data source authentication and format adaptation. This prevents parsing exceptions when connecting to different platforms. Content with different update frequencies requires the interface to support both incremental pull and full synchronization modes. This adapts to different synchronization needs for quarterly white papers, monthly updates, and daily briefings. Fields include numerical items with clear units. The interface must unify field mapping rules when returning data. This ensures external systems can directly parse numerical values with matching units. Single document length varies widely. The interface must configure long text processing thresholds. This avoids single request timeouts or truncated returned content.
Configuration Recommendations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Single in-depth refractory material research report has a long length, requiring sufficient time for text parsing and field extraction |
RECALL_TOP_K | Top 10–15 entries | Relevant content of professional refractory material research reports is relatively scattered, requiring a sufficient recall base to ensure retrieval relevance |
FIELD_MAPPING_RULE | Map raw material unit price → unit_price (yuan/ton), monthly output → monthly_output (thousand tons) | Core fields of refractory material research reports have clear units, requiring unified mapping to a standardized format recognizable by external systems |
SYNC_INTERVAL | Full synchronization at 00:00 daily, incremental synchronization at each hourly on-the-hour mark | Balances the timeliness of daily market briefings and the synchronization efficiency of quarterly and monthly white papers |
CORS_ALLOW_ORIGINS | Configure to the valid domain names of external systems | Prevents cross-domain errors during front-end interface calls, and adapts to the deployment domain name rules of external systems |
MAX_REQUEST_BODY_SIZE | 1000 MB | Adapts to large text requests generated after parsing some in-depth research reports, preventing request truncation |
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 specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- A 403 Forbidden error appears when the front end calls the HTTP interface, or the browser console displays a CORS cross-domain error. This happens when
CORS_ALLOW_ORIGINSis not configured correctly. Only partial domain names may be allowed, or the domain name of the target external system is missing. - The unit field in research report data received by the external system is empty, or the numerical value does not match actual values. This occurs when
FIELD_MAPPING_RULEis not configured. Native research report fields are not mapped to standardized fields, so external systems cannot recognize unit information. - A custom interface call does not trigger after a user inputs a specified keyword, and the default AI answer is returned directly. This happens when keyword trigger rules and external interface callback parameters are not configured. The corresponding trigger logic is not bound.
How to Verify Successful Configuration
- Send a test request. Check if the returned response header includes the correct
Access-Control-Allow-Originfield. This confirms the cross-domain configuration is active. - Upload a test refractory material research report. Check if the interface returns fields that include the mapped standardized fields and corresponding units. This confirms the field mapping configuration is active.
- Trigger an incremental synchronization task. Check if the external system only pulls newly added research report content. This confirms the synchronization interval configuration is active.
- Send a retrieval request for a long-text research report. Check that the interface does not return a timeout error. This confirms the parsing timeout configuration matches current business needs.
