What the data for this category looks like
Financial report data for the optical and optoelectronic category comes primarily from periodic reports and temporary announcements publicly disclosed by domestic and overseas stock exchanges. Update cycles fall into two categories: fixed and irregular. Fixed cycles include quarterly, semi-annual, and annual reports. Irregular temporary announcements cover sudden events such as production capacity changes, new product mass production, and large customer cooperation.
Data documents include general financial fields and category-specific business fields. General fields include revenue, net profit, cash flow, and similar items. Specific fields include panel shipment volume, LED packaging output, camera module sales, product-specific gross margin, and similar items. Units are mostly hundreds of millions of yuan, millions of pieces, ten thousand units, and similar units. Data formats support both structured JSON and original announcement PDF attachments.
What constraints these characteristics impose on HTTP Interfaces and External Systems
The multi-dimensional business fields of optical and optoelectronic financial reports require interfaces to return structured segmented data. External systems must support filtering configurations for specified return fields. The combination of fixed and irregular update cycles requires interfaces to support queries by fixed reporting periods and custom time ranges, to meet the needs of pulling temporary announcements.
Category-specific shipment volume, production capacity, and other data require cross-period aggregate analysis, which increases single interface request latency. External systems must adapt to longer timeout thresholds. Additionally, some data must be linked to original announcement PDFs. Interfaces must support a dual return mode for structured data and attachment downloads.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
request_timeout | 300 seconds | Optical and optoelectronic financial reports require pulling multi-period cross-aggregate data. Single requests take a long time. The default timeout duration is insufficient to complete data pulling |
query_period_type | quarterly,annual,temporary | Covers fixed reporting periods and temporary announcement scenarios for category financial reports, matching disclosure cycles |
return_fields_filter | total_revenue,product_revenue,shipment_volume,gross_margin | Only pulls category-specific segmented business fields, reducing invalid data transmission and parsing costs |
incremental_sync_switch | true | Adapts to the irregular update feature of temporary announcements, avoiding repeated pulling of full historical data |
api_auth_type | api_key | Most third-party optical and optoelectronic financial report data interfaces use API key authentication, complying with industry general configuration specifications |
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 individual analysis. Testing on available samples is recommended before finalizing settings.
Three common configuration mistakes
- An interface call returns the
getaddrinfo ENOTFOUNDerror. The cause is that optical and optoelectronic financial report data interfaces often configure enterprise-specific domain name whitelists. The dynamic domain name service is not authorized, leading to resolution failure. - Structured data returned by the interface lacks product segmented revenue fields. The cause is that the
return_fields_filterparameter is not specified. The default returned general fields do not cover category-specific business data. - A call has no response for an extended period and triggers a timeout error. The cause is that the
request_timeoutparameter is not adjusted. The default short timeout cannot adapt to the latency of multi-field cross-period aggregation.
How to confirm configurations are correctly set
- Call the test interface. Check if the returned fields include category-specific optical and optoelectronic financial report fields such as product shipment volume and segmented revenue. Confirm that the
return_fields_filterconfiguration takes effect. - Trigger an incremental pull task. Check if only newly announced data within the specified reporting period is returned. Confirm that the
incremental_sync_switchconfiguration is correct. - View interface call logs. Confirm that the
request_timeoutparameter matches actual pull latency, and no timeout errors occur. - Verify domain name resolution and whitelist configurations. Confirm that the domain name used by the workflow node can be resolved normally, and has been added to the interface authorization whitelist.
