What the data for this category looks like
Financial report data for the paint and ink category comes primarily from listed company periodic reports, public statistical data from industry associations, and third-party basic chemical data platforms. Two data update schedules apply: listed company financial reports are updated quarterly and annually, while industry supply and demand data is updated monthly. The structure of a single financial report document includes fields such as core financial indicators, raw material procurement proportion, detailed production capacity and output data, and environmental compliance expenditures. Most raw material price fields use yuan per kilogram as the unit, production capacity uses tons per year as the unit, and revenue detail fields are priced in ten thousand yuan.
Constraints imposed on HTTP interfaces and external systems by these characteristics
The characteristics of financial report data for the paint and ink category create clear constraints for HTTP interface and external system integration. Data from multiple sources must adapt to different authentication rules. Industry association data interfaces require dedicated API key configuration. Listed company financial report interfaces require confirmation of compliant official data call permissions. Different update schedules require scheduled synchronization task trigger cycles to match. Quarterly financial report synchronization requires quarterly-level triggers, while monthly industry supply and demand data requires monthly triggers. Structured parsing requirements for multiple fields require interface return formats to support precise extraction of specified fields. Unit consistency checks must be added during data transfer to avoid analysis deviations caused by mismatched units across data sources.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | A single paint and ink financial report PDF usually contains multiple pages of financial details, and 300 seconds covers the full parsing and interface request duration |
UPLOAD_FILE_MAX_SIZE | 200 MB | Single annual financial report PDFs typically range from 100 to 150 MB, so 200 MB provides a reasonable buffer |
REQUEST_RETRY_TIMES | 3 retries | Third-party chemical data interfaces may experience occasional fluctuations, and limited retries reduce the probability of synchronization failures |
SYNC_CRON_PATTERN | "0 0 3 * * 2" | Listed company financial reports are usually disclosed within 15 days after the end of a quarter. Synchronizing at 3 AM every Tuesday covers the latest publicly available data |
FIELD_FILTER_LIST | ["raw material procurement proportion", "capacity utilization rate", "revenue classification"] | Focus on core analysis fields for paint and ink financial reports, filtering non-essential content to improve interface processing efficiency |
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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom:
413 Request Entity Too Largeerror returned during interface calls. Cause: TheUPLOAD_FILE_MAX_SIZEparameter is not correctly configured, causing financial report files exceeding the threshold to be blocked. - Symptom: Empty content returned after calling an external rearrangement interface, with missing structured analysis results. Cause: Reasonable recall count parameters are not configured for long text from paint and ink financial reports, exceeding the maximum return count limit of the interface.
- Symptom:
504 Gateway Timeouterror returned after a scheduled synchronization task triggers. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and the long document parsing duration exceeds the interface gateway limit.
How to Verify Proper Configuration
- Initiate an interface call test with a standard-sized financial report file, check if the returned results include the preset core analysis fields.
- View the execution logs of scheduled synchronization tasks, confirm that the task trigger cycle matches the preset update schedule.
- Simulate a temporary exception scenario for third-party interfaces, check if the retry process is triggered according to the configured retry rules.
- Extract some data fields returned by the interface, compare them against the preset unit rules, confirm that the unit consistency check is working correctly.
