What the Data for This Category Looks Like
Core data supporting precious metals marketing content comes from authoritative market sources including the Shanghai Gold Exchange, London Bullion Market Association, and contract quotes from domestic futures exchanges. Data updates occur via real-time push or pull every 10 seconds. Each individual data document has a clear structure, containing fields such as product code, latest transaction price, price change range, position volume, and trading volume, among others.
Price units vary by product: gold uses yuan per gram, silver uses yuan per kilogram, and platinum uses yuan per gram. Some interfaces also return auxiliary fields including daily opening price, highest price, and lowest price.
Constraints Imposed on HTTP Interfaces and External Systems
Real-time market update requirements mean HTTP interface request timeouts must be controlled within 5 seconds. This prevents delayed display of outdated price data in marketing content.
The multi-field structure and differentiated unit requirements mean explicitly specifying return fields during interface requests. It also requires adding unit verification and conversion logic during data parsing, to ensure price display aligns with user habits for different products.
Cross-authoritative data source calls require configuring multi-source switching external system links. This also involves handling differences in authentication tokens and request headers across interfaces, as well as call frequency limits for some interfaces, to avoid blocking due to exceeding limits.
The timeliness requirement of marketing content means avoiding long-term local caching of market data. Only temporary caching within 10 seconds is permitted.
How to Configure
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
requestTimeout | 3–5 seconds | Aligns with the update frequency of precious metals real-time market data, avoids delayed outdated data |
returnFields | Specify core fields such as symbol,price,change,volume | Reduces redundant data transmission, meets the lightweight display needs of marketing content |
qpsLimit | 100 requests per minute | Matches the call frequency limits of most precious metals market interfaces, prevents triggering rate limiting |
cacheDuration | 8–10 seconds | Balances data timeliness and interface call pressure, meets the real-time update business requirements |
authType | Configure API keys or tokens as required by the interface | Adapts to authentication rules of different authoritative data sources, ensures valid interface calls |
responseParseMode | JSON format parsing | Most precious metals market interfaces return standard JSON structures, simplifies data processing workflows |
The parameter values provided on this page are common 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
- Phenomenon: Interfaces return 401 unauthorized errors, or identity tokens fail verification. Cause: Token configurations are not updated per the latest authentication rules of precious metals market interfaces. Some interfaces regularly rotate token keys.
- Phenomenon: HTTP requests time out, leading to slow loading of marketing content. Cause:
requestTimeoutis set to more than 10 seconds, exceeding the real-time market update cycle and resulting in outdated data. - Phenomenon: Parsed data units do not match expectations, such as gold displayed as yuan per kilogram. Cause: No unit verification logic is added during data parsing, and unit conversion rules are not adjusted for different precious metal products.
How to Confirm Proper Configuration
- Send a test request, check if returned fields match the configured
returnFields, and confirm only required core data is retrieved. - Send multiple consecutive requests, check if interface rate limiting is triggered, and confirm
qpsLimitcomplies with current interface call rules. - Parse returned price data, verify units match the target precious metal product, and confirm unit conversion logic functions correctly.
- View interface request logs, confirm authentication tokens are correctly added to request headers, and ensure no authentication failures occur.
