What the data for this category looks like
Data sources for precious metal financing daily reports include official market APIs from the Shanghai Gold Exchange and London Bullion Market Association, plus credit ledger APIs from cooperating financial institutions. Full data updates for the previous trading day are completed every early morning. The documentation presents data in structured tables, with fields including trading product code, product name, daily financing approval quota, pledged reference unit price, credit validity period, and more. Quota units are ten thousand yuan, unit price units are yuan/gram, and validity period units are calendar days.
Constraints imposed by these characteristics on deployment and upgrade
Multiple data sources from exchanges and financial institutions require configuring multi-source matching rules during deployment. This ensures daily report data for different products is pulled from the correct channel. The daily full update schedule requires scheduled task trigger times to align with post-close data release times of exchanges. This avoids pulling unready raw data. During upgrades, scheduled tasks must remain uninterrupted. Interruptions will cause missing daily report data. If data parsing rules are modified, historical daily report field formats must be compatible. This prevents old data from failing to display properly. Strict data validation logic must be configured during deployment, per the validity requirements for financial data. This prevents abnormal data from entering the knowledge base.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
SCHEDULE_CRON | 0 30 2 * * ? | Aligns with the T+1 data update schedule of precious metal exchanges, ensuring daily report generation and synchronization for the previous day are completed at 2:30 AM daily |
HTTP_REQUEST_TIMEOUT | 600 seconds | Allocates sufficient time for cross-exchange API requests and data splicing, avoiding timeout interruptions to daily report generation tasks |
MULTI_SOURCE_MATCH_RULE | Match corresponding data sources by product code | Adapts to the data source sharding requirement for products listed on multiple exchanges in precious metal financing daily reports |
DATA_VALIDATION_RULES | Validate that unit price > 0, quota ≥ 0, and period ≥ 1 | Filters abnormal data to ensure the validity of financing daily reports |
BACKUP_DIR | /data/fastgpt/backup/precious-metal-report | Backs up historical configurations and daily report data before upgrades, enabling rapid rollback |
ALLOWED_ORIGINS | https://*.your-domain.com, ios-app://your-bundle-id | Adapts to multi-terminal access requirements, avoiding cross-domain errors that prevent interface loading |

Three Common Mistakes
- Phenomenon: Exposing the external network via ngrok results in a white screen in the chat interface on iOS devices. macOS and Windows devices access normally. Cause:
ALLOWED_ORIGINSdoes not include the iOS app bundle ID or ngrok's temporary domain, triggering cross-domain restrictions. - Phenomenon: Daily report generation tasks fail frequently after deployment. Docker container logs display
HTTP_REQUEST_TIMEOUTerrors. Cause: TheHTTP_REQUEST_TIMEOUTconfiguration value is too small, with insufficient time allocated for cross-data-source API requests and data splicing. - Phenomenon: After upgrading to version 4.9, Docker-deployed services fail to start. Logs show configuration file format errors. Cause: Original configuration files were not backed up, and the upgrade overwrote custom
SCHEDULE_CRONandDATA_VALIDATION_RULESconfigurations, or the upgrade did not adapt to configuration item changes in version 4.9.
How to Confirm Proper Configuration
- Check scheduled task logs to confirm daily report data is pulled and parsed within the specified time each day. Verify there are no
HTTP_REQUEST_TIMEOUTor data validation failure errors in the logs. - Access the configured allowed domains and terminals to confirm the chat interface loads normally, with no cross-domain related console errors.
- Manually trigger a daily report generation task, then verify the generated daily report document includes expected precious metal products, quotas, unit prices, and other fields, with no null or abnormal values.
- Perform an upgrade rollback test to confirm the backed-up configuration files can quickly restore the original service state.
