What the data for this category looks like
The financial report data for the plastics and rubber category comes primarily from publicly disclosed periodic reports of listed companies on exchanges, production and sales briefings from industry associations, and public information from bulk commodity spot platforms. Update schedules follow two cycles: quarterly and annual. Quarterly financial reports are released within 15 working days after the end of the quarter. Annual financial reports must be disclosed by the end of April of the following year.
Documents are provided in PDF or structured table formats. Relevant data is scattered across business segment reports, raw material procurement and cost structure chapters. Fields include segment revenue amounts, production capacity scale, raw material procurement proportion, and more. Units include ten thousand yuan, ten thousand tons, and others.
Constraints imposed on HTTP interfaces and external systems
The scattered data sources, diverse formats, and layered update cycles for the plastics and rubber category create multiple constraints for HTTP interface and external system integration. A unified retry and timeout fallback mechanism must be configured to support docking with multiple external data source interfaces. Routing rules with different parsing logic must be built into the interface to adapt to PDF and structured table document formats. Data timestamp verification logic must be added to trigger pull tasks according to quarterly and annual update schedules, preventing repeated pulls of old data. Field mapping and unit conversion rules must be configured to handle differences in field names and units across different data sources, ensuring accurate data alignment.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Plastics and rubber financial report PDFs usually contain multiple pages of business details, and complete parsing takes a long time. 600 seconds covers the full parsing process |
externalApiRetryCount | 2 retries | Financial report data sources are mostly public industry platforms with medium interface stability. 2 retries cover temporary network fluctuations |
fieldMappingStrategy | Match by business keywords | Field names for the plastics and rubber segments of different listed companies vary. Keyword matching automatically aligns target fields |
dataSyncCron | 0 2 * * 1,4,7,10 | Matches the update schedule of full pull at quarter end and daily incremental verification. Triggers basic verification at fixed times each week |
unitConversionEnabled | Enabled | Units for revenue and production capacity vary across different data sources. Enabling conversion ensures unified data formatting |
streamResponseChunkSize | 800-1200 characters | Financial report analysis results are usually lengthy. This chunk size balances front-end display smoothness and interface transmission 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 specific analysis, and it is recommended to test on your own samples before finalizing.
Three Common Configuration Mistakes
- Phenomenon: Calling an external financial report data source interface returns a
400status code, and the response body prompts field mismatch. Cause: ThefieldMappingStrategyconfiguration is not enabled, hard-coded fields are used directly to pull data, and field differences across different listed companies are not adapted. - Phenomenon: When streaming financial report analysis results, clicking embedded links only overwrites the current page and does not open a new window. Cause: No link jump rules for streaming responses are configured, and the front-end rendering logic does not add new window trigger attributes for external links.
- Phenomenon: The analysis content displayed in conversation logs is inconsistent with the actual returned financial report data, and the log content remains the same after multiple calls. Cause: No expiration time is configured for data cache, and old financial report data cache is not automatically cleaned, resulting in repeated return of old data.
How to Verify Successful Configuration
- Manually trigger a data pull task, check whether the fields returned by the interface match the configured
fieldMappingStrategy, and confirm that fields are correctly aligned. - View the logs associated with the
PARSE_FILE_TIMEOUT_SECONDSconfiguration, confirm that parsing duration does not exceed the set threshold, and no timeout errors occur. - Test the streaming output function, click links in the returned content, confirm that they jump to a new page, and that return speed can be adjusted via
streamResponseChunkSize. - Check the data synchronization scheduled task logs, confirm that they trigger normally according to the cycle set in
dataSyncCron, with no missed or repeated pulls.
