What data for this category looks like
Data for special steel financing daily reports comes from transaction financing ledgers for special steel categories on domestic special steel industry chain supply chain financial service platforms and regional bulk commodity trading markets. Data collection and updates are completed by 18:00 on the same trading day. Files are available in structured JSON or CSV format. They include the following fields: statistical date, special steel sub-variety code and name, financing entity unified social credit code and name, single financing amount, financing term, brand and specification of pledged special steel, and daily market valuation of pledged assets. The units for amount and valuation are fixed as ten thousand RMB. The financing term unit is natural day.
Constraints for HTTP Interfaces and External Systems
The wide range of special steel sub-varieties and structured qualification and valuation information in fields require HTTP interfaces to support multi-dimensional query parameter filtering. The fixed update time of before 18:00 on trading days means external system scheduled pull tasks must align with this time window. This avoids pulling temporary data that has not completed collection. Fields such as unified social credit code and brand specification have strict validation requirements. Interfaces must support integrity checks for returned fields. This prevents business exceptions caused by external systems receiving incomplete data. Financing amount and valuation use ten thousand RMB as a unified unit. Interfaces must standardize unit formats, eliminating the need for external systems to perform additional conversions.
How to set configurations
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
apiRequestTimeout | 600 seconds | The data source interface for special steel financing daily reports may take a long time to aggregate multi-source data. An overly short timeout setting will cause pull failures |
requestRetryTimes | 3 times | Bulk commodity trading platform interfaces may experience temporary fluctuations. Retries reduce the probability of single pull failure |
responseFieldWhitelist | Statistical Date, Special Steel Variety Name, Financing Amount, Pledge Product Brand | Filter non-essential fields to reduce data processing pressure on external systems. Matches core business fields for special steel financing daily reports |
scheduleCron | 0 30 17 * * 1-5 | Aligns with the time window for special steel financing daily reports to complete updates before 18:00. Triggering pulls at 17:30 ensures complete same-day data is obtained. Runs only on trading days |
requestParamPrecision | exactMatch | Special steel varieties have high precision requirements for sub-brands. Exact matching avoids pulling irrelevant ordinary steel data |
responseUnitCheck | enabled | Financing amount and valuation for special steel financing daily reports use ten thousand RMB as a fixed unit. Enabling unit validation prevents the interface from returning data with non-standard units |
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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- The symptom is an HTTP interface call returning a
400 Bad Requeststatus code, with the field特钢品种名称empty. The cause is thatresponseFieldWhitelistis not configured, or the whitelist includes non-required fields. This causes the interface to filter out core business fields. - The symptom is a scheduled pull task failing to obtain same-day data after 19:00 on workdays, returning empty results. The cause is that the scheduled task's
scheduleCronis configured as0 0 18 * * *. This does not account for update delays on some trading platforms, and misses the same-day data collection window. - The symptom is that the HTTP module body content cannot be edited normally, with the deployment version
4.8.15-fix3. The cause is that the HTTP request configuration panel in this version has rendering abnormalities in the body editing area. Manually edit the request body format via the code view.
How to Confirm Configurations Are Set Correctly
- Call the configured HTTP interface, check if the returned JSON data includes core business fields, and if field units match the preset format.
- Check the scheduled task execution logs, confirm that pull requests are triggered at the specified time on each trading day, and that there are no records of timeouts or retry failures.
- Manually modify the query parameters to the specified special steel variety, verify that the interface returns data only containing financing information for that category.
- Compare the data stored in the external system with the original data returned by the interface, confirm field integrity and unit consistency.
