What this type of data looks like
Steel trade yield-related data is sourced from domestic bulk commodity spot trading platforms, futures exchange market APIs, and internal enterprise purchase-sales ledgers. There are two update rhythms for the data: Spot market data is synchronized and updated hourly. Core calculation data such as purchase-sales margin and gross profit per ton is updated after daily business settlement is completed. Final daily report data is generated every early morning. The document structure uses structured tables, with fields including trade variety, purchase unit price, sales unit price, unit purchase-sales margin, gross profit per ton, and monthly cumulative trade volume. Units are unified as physical measurement and currency units such as yuan/ton and ton. No percentage-based indicators are included.
Constraints Imposed by These Characteristics on Sharing and Embedding
The layered update feature of steel trade yield data requires separating static snapshot and dynamic data modes for sharing and embedding. Static sharing must fix the calculation results of the current day. Dynamic embedding must adapt to the synchronization frequency of real-time market data. The fields include multiple sets of numerical values with physical units. The embedding container must reserve sufficient width and height to avoid content overflow or truncation. Some data connects to third-party bulk commodity data sources. Sharing links must configure cross-domain authorization for the corresponding data source to prevent data requests from being blocked. The daily report data generation cycle is fixed. The scheduled update task for sharing must match this cycle to avoid displaying expired non-daily settlement data.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
shareEmbedDomainWhitelist | ["*.steel-trade.com", "*.internal-steel-platform.com"] | Restrict authorized domains for embedding and sharing, prevent unauthorized sites from calling enterprise operating data |
shareUrlParamMapping | {"product": "steel_variety", "date": "report_date"} | Map external incoming trade variety and report date parameters to globally recognizable variables for the model, adapt to multi-variety daily report queries |
iframeEmbedHeight | 600–800 pixels | Adapt to the multi-field table structure of steel trade daily reports, avoid truncation of calculation data for standard varieties |
shareApiAuthType | Signature verification mode | Ensure data transmission security when connecting to third-party bulk commodity data sources, prevent request parameters from being tampered with |
shareRefreshInterval | 3600 seconds | Match the hourly update frequency of spot market data, ensure real-time synchronization of market data on embedded pages |
anonymousShareEnable | Disabled | Steel trade data belongs to sensitive enterprise operating information, disabling login-free sharing restricts access permissions |
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 specific analysis, and it is recommended to test on your own samples before finalizing.
Three Common Configuration Mistakes
- The embedded iframe does not display robot reply content in the production environment, but displays normally in the local debugging area. This occurs because
shareEmbedDomainWhitelistis not configured, and the production environment domain is not added to the whitelist, so cross-domain requests are blocked. - After passing custom trade variety parameters to the sharing link, the model does not load the daily report data for the corresponding variety. This occurs because
shareUrlParamMappingis not configured, and the parameters passed via the URL are not mapped to global variables readable by the model. - The yield data displayed on the embedded page fluctuates in real time and does not match the enterprise's internal daily settlement calculation results. This occurs because
shareSnapshotEnableis not enabled, the sharing link defaults to synchronizing real-time market data, and the daily settlement snapshot is not fixed.
How to Verify Successful Configuration
- Copy the generated embedding code, paste it into the page of the configured whitelist domain, and check if the yield rate daily report content is fully displayed.
- Pass custom trade variety parameters to the sharing link, and verify whether the model loads the calculation data for the corresponding variety.
- Check the update frequency of the embedded page, and confirm that it matches the configured
shareRefreshInterval. - After disabling anonymous access permissions, try to access the sharing link through an unauthorized domain, and confirm that the data cannot be loaded.
