What this category of data looks like
Data on railway and highway yields and market trends comes primarily from road network monitoring platforms managed by transportation authorities and publicly disclosed information from listed railway and highway operating enterprises. Daily trading data is synchronized after market close each day. Full road network operating revenue statistics are updated each natural month. The data uses a multi-dimensional structured dataset format. It includes fields such as route identification, operating mileage, passenger and freight turnover, unit operating revenue, and daily price fluctuation. Field units are as follows: operating mileage is measured in kilometers, passenger and freight turnover in ten thousand ton-kilometers, unit operating revenue in yuan per hundred ton-kilometers, and daily price fluctuation in yuan.
What constraints these characteristics impose on sharing and embedding
Multi-source data requirements mean shared content must clearly label data update times and sources to avoid information confusion. Daily updated market data requires embed component cache periods to not exceed one calendar day. Otherwise, outdated information will be displayed. The multi-field structured dataset requires embed configurations to support custom display fields. This adapts to information filtering needs across different scenarios. The special unit operating revenue field, which uses yuan per hundred ton-kilometers, requires embed components to preset unit explanations. This prevents audience misunderstanding. Monthly updated full road network statistics require sharing links to separate entrances for real-time market data and historical statistical data. This stops users from confusing data dimensions.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
share_max_links_per_app | 100 | Matches the high-frequency sharing needs of the railway and highway sector, and adapts to multi-scenario distribution requirements |
embed_cache_ttl | 86400 seconds | Matches the daily update schedule of railway and highway market data, and avoids displaying outdated data |
embed_show_fields | Line Identification, Operating Mileage, Unit Operating Revenue, Daily Price Fluctuation | Matches core fields of railway and highway data, and reduces interference from irrelevant information |
embed_language | zh-CN | Adapts to the reading habits of domestic audiences, and fixes issues on English interfaces |
share_auth_required | false | Adapts to public sharing scenarios, and aligns with the default configuration logic of version 4.9.0 |
embed_unit_display | Unit Operating Revenue: yuan/100 ton-kilometers | Clearly labels units for special fields, and prevents audience misunderstanding |
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 targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration errors
- Scenario: The embed interface displays English content and cannot be switched to Chinese. Cause: The
embed_languageparameter is not configured, or is incorrectly set toen-US. - Scenario: The number of shared links cannot exceed 10. An error about link limit is returned when trying to create the 11th link. Cause: The
share_max_links_per_appconfiguration item is not adjusted, and the default limit of 10 remains in place. - Scenario: The identity authentication logic for shared links does not meet expectations in version 4.9.0, or the corresponding configuration item cannot be found. Cause: The configuration logic for
share_auth_requiredbetween version 4.6.4 and 4.9.0 is confused, and the parameter is not adjusted according to the new version's configuration rules.
How to verify correct configuration
- Access the preview address of the embed component, and check that the displayed fields exactly match the list set in
embed_show_fields. - Try to create more than 10 application shared links, and confirm that the system allows creation and no link limit error is returned.
- Load the embed iframe page, and check that the interface text language matches the set
embed_languagevalue. - View the access logs of shared links, and confirm that the identity authentication logic aligns with the configuration of
share_auth_required.
