HTTP Interfaces and External Systems for Auto Parts

What Data for This Category Looks Like

Data primarily comes from public periodic reports of domestic A-share and Hong Kong-listed auto parts enterprises, plus segmented revenue statistics from third-party industry databases. Quarterly reports are updated within 30 days after the end of each quarter. Annual reports are disclosed by April 30 of the following year. The document structure includes consolidated balance sheets, income statements, cash flow statements, revenue breakdowns for segmented businesses such as chassis components and in-vehicle electronic systems, capacity utilization rates, and supply chain cooperation data. Fields include revenue (unit: RMB), attributable parent company net profit (unit: RMB), inventory turnover days, supporting OEM order amounts, and more. Some overseas-listed enterprises disclose financial reports in foreign currencies such as USD, so unit conversion is required.

Constraints Imposed on HTTP Interfaces and External Systems

Public financial report data comes from scattered sources. Connections to securities exchange disclosure interfaces and third-party industry database interfaces create constraints for multi-source authentication configuration. Fixed update cycles require HTTP nodes to be configured with scheduled pull scheduling. The schedule must match financial report disclosure time windows to avoid invalid requests or delayed data. Segmented business revenue requires multiple field breakdowns. Interface return fields must strictly map to FastGPT knowledge base fields to avoid missing revenue data for segmented categories such as chassis components and in-vehicle electronic systems. For fields disclosed in multiple currencies, HTTP interfaces must support exchange rate conversion parameters, or standard unit conversion logic must be configured in the node. When connecting to internal enterprise supply chain systems, customized parameters such as OEMs and component types must be passed. This requires adjusting the interface request body structure.

How to Configure Settings

Configuration Item	Recommended Value	Rationale
`HTTP_REQUEST_TIMEOUT`	`600 seconds`	Single annual financial reports for auto parts have large data volumes. Pulling complete data via the interface takes significant time. This setting avoids early timeout truncation
`RESPONSE_FIELD_MAPPING`	`{"总营收":"total_revenue","底盘部件营收":"chassis_revenue","车载电子营收":"electronics_revenue","归母净利润":"net_profit"}`	Core segmented fields for auto parts financial reports must strictly map to knowledge base search fields to ensure subsequent analysis accurately extracts segmented category data
`SCHEDULER_CRON_EXPRESSION`	`0 0 12 15,30 * *`	The A-share quarterly report disclosure window is within 30 days after the end of the quarter. This scheduling frequency pulls the latest data promptly after disclosure, avoiding delayed data
`UPSTREAM_API_AUTH_TYPE`	`Bearer Token`	Most securities exchange disclosure interfaces and third-party industry database interfaces use Bearer Token authentication. This setting adapts to the security verification requirements of general external interfaces
`CURRENCY_CONVERSION_ENABLE`	`true`	Some overseas-listed auto parts enterprises disclose financial reports in USD. Enable automatic conversion to RMB in the HTTP node to unify analysis units
`MAX_RESPONSE_SIZE`	`100 MB`	Structured data or PDF attachment return values from single annual financial report interfaces may exceed conventional limits. Adjust the allowed response volume to obtain complete data

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Configuration Mistakes

Scenario: Calling an external financial report interface returns a Failed to fetch error with status code 413 Request Entity Too Large. Cause: The MAX_RESPONSE_SIZE configuration was not adjusted. Single financial report data exceeds the interface's allowed response volume limit.
Scenario: Financial report data in the knowledge base has not been updated for a long time. Search results show old data. Cause: The SCHEDULER_CRON_EXPRESSION configuration is incorrect. It does not match the financial report disclosure time window, leading to too low pull frequency or deviated time nodes.
Scenario: The HTTP node returns BLOB-format financial report attachments. Downloads cannot be triggered directly in the chat window, and the attachment field is empty. Cause: The correct BLOB_CONTENT_TYPE was not configured in the HTTP node, and the file stream logic for returned content was not enabled.

How to Verify Correct Configuration

Initiate a single HTTP request. Check if the returned fields match those configured in RESPONSE_FIELD_MAPPING to confirm the data extraction logic operates normally.
View the scheduled scheduling log. Confirm that the execution time of the most recent pull task matches the time configured in SCHEDULER_CRON_EXPRESSION, and data updates meet expectations.
Test a large-volume data request. Check if the HTTP_REQUEST_TIMEOUT and MAX_RESPONSE_SIZE configurations can fully receive the returned content without truncation or timeout errors.
Test multi-currency data conversion. Confirm that when CURRENCY_CONVERSION_ENABLE is enabled, overseas financial report data units are automatically converted to RMB, and field values meet expected standards.
