What data for this category looks like
Data for special steel yield and daily market reports comes from domestic authoritative special steel industry trading platforms, steel mill ex-factory price announcements, and spot matching data. Two update schedules apply: spot market prices update daily after market close, while ex-factory price data updates once weekly. Data uses structured table format. Each entry includes subcategory, specification model, origin identifier, latest price range, historical period comparison value, and total daily trading volume. Units are uniformly yuan/ton and ton, with no additional percentage-based statistical items. Data fields cover professional parameters for special steel subcategories. Retain original field names to ensure professional readability.
What constraints do these characteristics impose on sharing and embedding workflows
The large number of special steel subcategories and complex specification parameters require precise filtering configuration for sharing and embedding. This avoids mixing irrelevant data from ordinary steel categories. Differentiated data update frequencies require embedded components to use a reasonable cache duration. This balances data timeliness and server load. Field units use professional metrics: yuan/ton and ton. Retain original unit formats during embedding. Do not automatically simplify or replace units. Special steel daily reports include many professional terms. Retain original field names for shared content. Do not automatically translate or simplify terms, as this disrupts information access for professional users. Special steel market data has multiple display dimensions. Embedded components must support custom display fields. This prevents redundant information from interfering with reading of core content.
How to configure settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
embed_cache_seconds | 3600 seconds | Special steel spot market prices update daily. A 1-hour cache balances data timeliness and server load |
share_link_expire | 7 days | Covers the complete release cycle of special steel weekly and daily reports, to avoid shared links expiring early |
embed_show_history | Disabled | Special steel yield daily reports are one-time broadcast content. No need to display historical conversation records |
iframe_allow_list | Fill in business domain name list | Restrict embedded domains to prevent unauthorized pages from calling special steel market data |
embed_custom_fields | ["product name", "latest price", "month-on-month change"] | Matches core display fields for special steel daily reports, to avoid redundant information interfering with reading |

Three common mistakes
- Symptom: After embedding into a VUE project, the page displays
localhost:3000/chat/and does not show business domain names. Cause: Theiframe_allow_listparameter is not configured, and the local debug domain name is used by default. - Symptom: The login-free embedded component in version 4.9.1 cannot view historical records, and historical data can be queried in logs. Cause: The
embed_show_historyconfiguration item is not enabled, or historical record rendering is abnormal due to version adaptation issues. - Symptom: The embedded special steel market component in a mini-program cannot display properly, with a domain verification failure prompt. Cause: The mini-program does not support iframe cross-domain domain verification, and the general iframe embedding method is used instead of the mini-program-specific embedding solution provided by FastGPT.
How to verify successful configuration
- Copy the generated embedding code, insert it into a local test page, and check if special steel-specific yield daily report content is displayed, and no default general chat interface appears.
- Access the generated shared link, confirm it can be accessed normally within the configured validity period, and cannot be opened after expiration.
- Embed components on pages of different business domains, verify that unauthorized domains cannot load the component, and authorized domains can display complete content normally.
- Check that the display fields of the embedded component match the configured
embed_custom_fields, with no redundant or missing core fields.
