What the data for this category looks like
The data for refractory materials intelligent due diligence reports primarily comes from factory quality inspection reports of production enterprises, industry association sampling inspection databases, and upstream raw material supply ledgers. Data update frequency follows production batches. Single-batch finished product inspection reports are updated within 24 hours after production. General industry standard data is synchronized once per quarter. The structure of a single report document includes three modules: batch identifier, raw material proportion details, and core performance parameters. Core fields include refractoriness (unit: ℃), bulk density (unit: g/cm³), number of thermal shock stability tests, and chemical composition proportion. There are no nested multi-level subfields.
What constraints these characteristics impose on HTTP Interfaces and External Systems
Because data is updated by production batch and update times are not fixed, interfaces must support precise queries by batch identifier. Relying solely on time range filtering is not recommended. Core performance parameters have fixed unit requirements. Interface return fields must strictly match the preset unit system to avoid unit conversion errors in external systems. Multiple data sources require interfaces to accommodate format differences across data sources, while outputting a standardized field structure externally. High-frequency single-batch data updates increase real-time call demand for interfaces. It is necessary to limit the batch query frequency per single IP to prevent system overload.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
QUERY_BATCH_MODE | Precise query by batch ID | Adapts to the data update feature of refractory materials by production batch, avoids redundant data returns from time range queries |
RESPONSE_FIELD_MAPPING | Fixed mapping to batch_id/refractoriness/bulk_density/thermal_shock_resistance | Matches the standard field structure of refractory materials due diligence reports, simplifies field parsing logic for external systems |
CACHE_EXPIRE_SECONDS | 86400 seconds | Aligns with the 24-hour update cycle for single-batch reports, balances real-time performance and interface load |
RATE_LIMIT_PER_IP | 100 requests per hour | Addresses high-frequency single-batch query demand, prevents interface overload from bulk calls |
UNIT_CONVERSION_ENABLE | Enabled | Uniformly returns the preset unit system, avoids errors from self-conversion by external systems |
BATCH_QUERY_MAX_SIZE | 50 batches per request | Controls data volume per single request, avoids interface timeouts or overly large response bodies |
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. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- An HTTP 401 Unauthorized error is returned after calling the interface, and the error persists after confirming the credential configuration is correct. Cause: Permission scope was not configured for the dedicated interface for refractory materials data. Generic credentials cannot cover access permissions for dedicated data sources.
- HTTP requests are repeatedly called regardless of question classification branches, resulting in exceeded interface call limits. Cause: HTTP requests were not configured as globally reusable nodes, causing independent calls to be triggered for each branch.
- Performance parameter units received by external systems are inconsistent, leading to numerical calculation errors. Cause: The
UNIT_CONVERSION_ENABLEconfiguration was not enabled, and non-standard unit data from original data sources was returned directly.
How to Verify Configurations Are Correctly Set
- Call the interface for a specified batch ID, verify that return fields exactly match the preset
RESPONSE_FIELD_MAPPING. - Simulate batch query requests, confirm that interface return request counts comply with the preset
RATE_LIMIT_PER_IPrules. - Check that returned performance parameter units are uniform, verify that the
UNIT_CONVERSION_ENABLEconfiguration is active. - Trigger the credential verification process, confirm that credentials with different permission scopes can correctly access corresponding data sources.
