What this category of data looks like
Glass market and yield data draws from two primary sources: glass futures trading data from the Zhengzhou Commodity Exchange, and national major spot market quotation data aggregated by the National Building Materials Circulation Association. Futures data updates in real time during trading sessions on active trading days. Spot data is compiled and published before 16:00 each day. Structured documents use table formatting with fixed fields: product name, specification parameters, production origin, daily listed price, previous trading day’s listed price, price change amount, and statistical date. Listed price and price change amount use the unit yuan per weight box. Specification parameters typically include detailed attributes such as glass thickness and type.
Constraints for Sharing and Embedding Workflows
The multi-source nature, multi-specification attributes, and fixed field structure of glass data create clear constraints for sharing and embedding. First, the differing update cadences between futures and spot data require embedding configurations to set separate refresh intervals for each data source, to avoid displaying expired or unupdated data. Second, the wide range of specification variants requires sharing links or embedding code to support filtering data by fields such as specification and origin. Without this filtering, embedded content will be overly complex and fail to meet precise viewing needs. Third, the fixed fields and unit requirements mean embedding templates must strictly match preset fields, to prevent incorrect unit display or missing core fields that could impair user judgment of market trends. Finally, the structured table data requires embedding containers to reserve sufficient column width and layout space, to ensure all fields are displayed clearly.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
embed_refresh_interval | Set 300 seconds for futures data sources, 86400 seconds for spot data sources | Matches the actual update frequency of glass futures and spot data |
embed_show_fields | Product Variety Name, Specification Parameters, Daily Listed Price, Price Change Amount, Statistical Date | Covers core display dimensions of glass market data |
embed_data_source | ["spot", "futures"] | Meets user viewing needs for both spot and futures glass market data |
embed_cache_ttl | Set 300 seconds for futures scenarios, 86400 seconds for spot scenarios | Aligns with refresh intervals to avoid cache expiration desync from data updates |
embed_cors_allowed_origins | ["https://building-materials-vertical-platform-domain"] | Restricts valid embedding domains to prevent cross-origin resource abuse |
embed_strict_mode | true | Ensures only fields permitted by configuration are returned, to avoid unintended data leakage |
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 Configuration Errors
- Embedded pages return a 504 status code after loading, showing data load timeout. Cause:
embed_api_timeoutis set too short, failing to cover the normal response duration of market data APIs. - Glass specification filter variables configured in embedded pages do not display. Cause: Custom parameter passing permissions for guest links are not enabled, preventing custom variables from loading.
- Embedded pages omit the "price change amount" field in displayed content. Cause: The field is not included in the
embed_show_fieldsconfiguration, or the field name is spelled incorrectly.
How to Verify Successful Configuration
- Open the preview interface of the embedding code, and confirm that displayed fields match the content configured in
embed_show_fields. - Switch data source types, and verify that refresh intervals align with the update cadence of the corresponding data.
- Test custom filter parameters, and confirm that glass data for specified specifications or origins can be correctly filtered.
- Check cross-domain access logs, and confirm that only configured domains can initiate embedding requests.
