What data for this category looks like
Data related to coke financial reports comes from periodic reports of domestic and overseas listed companies, commodity industry monitoring platforms, and futures exchange delivery databases. Update frequencies fall into three categories: quarterly and annual reports are updated every 3 and 12 months respectively, industry monitoring data is updated weekly, and delivery data is updated daily. Document structures include a core operating data module, an upstream-downstream linkage data module, and a financial indicator module. Fields include coke output, sales volume, unit cost, gross margin, and more. Output and sales volume are measured in 10,000 tons, unit cost is measured in yuan per ton, and most financial indicators are percentage values.
What constraints these characteristics impose on HTTP interfaces and external systems
The multi-frequency update requirement for coke data means interfaces must support high-frequency pulling and batch requests. Single financial report files include multiple associated supplementary pages and have large file sizes, so interfaces must support large file upload and parsing. Field units use non-standard writing, so external systems must support unit mapping configuration. Upstream-downstream linkage data requires association with external data sources, so interfaces must support cross-data source aggregation requests. Additionally, data formats vary widely across different sources, so external systems must have flexible format adaptation capabilities to avoid parsing failures.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 100 MB | Single PDF/Excel file for coke financial reports usually does not exceed 80 MB. Reserve 20% extra capacity to cover unusually large file scenarios |
AIPROXY_API_ENDPOINT | https://api-proxy.fastgpt.com/v1 | The official proxy address supports cross-domain requests and key verification, and adapts to multiple usage scenarios |
AIPROXY_API_TOKEN | Exclusive key generated by the platform | Used for interface identity verification to prevent unauthorized access. Rotate regularly to ensure security |
PARSE_TIMEOUT_SECONDS | 300 seconds | Coke financial reports include multiple associated supplementary sheets. Conventional parsing takes approximately 220 seconds. Reserve an 80-second buffer to avoid timeout interruptions |
BATCH_REQUEST_INTERVAL | 5 seconds | Daily delivery data interfaces have call frequency limits. Setting a fixed interval avoids triggering current limiting rules |
UNIFIED_UNIT_MAPPING | {"产量":"万吨","单位成本":"元/吨"} | Non-standard unit writing exists in coke financial report fields. Unified mapping ensures consistent data reading for downstream systems |
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- A 413 Request Entity Too Large error is returned when calling the interface. The cause is that the uploaded financial report file size exceeds the threshold set by the
UPLOAD_FILE_MAX_SIZEconfiguration. - Incorrect address or invalid key are entered when configuring
AIPROXY_API_ENDPOINTandAIPROXY_API_TOKEN. This causes the interface to return a 401 Unauthorized error or connection timeout. UNIFIED_UNIT_MAPPINGis not configured, leading to inconsistent units of parsed data fields. Downstream systems cannot properly read field values.
How to confirm configurations are set correctly
- Upload a coke financial report sample file that does not exceed the
UPLOAD_FILE_MAX_SIZEthreshold, and check that the interface returns a 200 OK status code. - Initiate a test request using the configured
AIPROXY_API_ENDPOINTandAIPROXY_API_TOKEN, and check that the returned result includes an identity verification passed indicator. - After configuring
UNIFIED_UNIT_MAPPING, parse sample financial report data, and verify that the units of the returned fields match the preset mapping rules. - After setting
BATCH_REQUEST_INTERVAL, initiate 3 consecutive high-frequency data pulling requests, and check that no current limiting related errors are triggered.
