What the Data for This Category Looks Like
The yield rate and market data for automated equipment comes from the built-in local market collection module and connected financial data gateways. The update rhythm aligns with the industry-standard daily report generation cycle, and one complete dataset is generated per day. The document structure uses structured JSON format, containing device unique identifier, trading target code, daily yield value, cumulative holding market value, benchmark reference value, and data update timestamp. Field unit rules: yield values are stored as dimensionless decimals, holding market value is denominated in CNY yuan, timestamps use ISO 8601 standard format, the number of fields per single data entry is fixed with no nested levels.
What Constraints Do These Characteristics Impose on HTTP Interfaces and External Systems
The fixed-cycle update feature requires external systems' HTTP calls to match the daily report generation rhythm, to avoid frequent requests that fetch unupdated empty datasets. The structured JSON format requires interface requests to specify the Accept: application/json request header, otherwise the device may return unexpected text format data. The presence of the device unique identifier field requires external systems to carry the corresponding parameter when calling the interface to match the exclusive data of a single device. The standard timestamp format requires external systems' parsing logic to support ISO 8601 format, to avoid time zone conversion or field parsing errors. The carrying capacity of a single-device interface is limited, so the frequency of batch requests must be controlled to avoid triggering rate limiting.
How to Set the Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
request_interval | 86400 seconds | Matches the daily daily report update cycle, avoids frequent calls that fetch unupdated empty data |
accept_header | application/json | Adapts to the structured JSON data format returned by automated equipment, ensures the interface correctly parses response content |
session_id_param | Use the session identifier field name preset in the workflow | Matches the workflow's context storage rules, avoids context association failure |
data_timeout | 300 seconds | Covers the maximum response duration for automated equipment data pulling, prevents request interruption due to network latency |
batch_request_limit | 10 items per request | Adapts to the QPS carrying limit of the single-device interface, avoids exceeding the device's processing capacity |
response_parse_mode | Parse timestamps in ISO 8601 format | Correctly converts the timestamp fields returned by the device, avoids format parsing errors |
The parameter values provided on this page are all conventional recommendations used as a starting point 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 settings.
Three Common Mistakes
- A
429 Too Many Requestsstatus code is returned by the interface call, and it is triggered multiple times consecutively. Cause: No reasonable request interval is configured, and frequent calls exceed the interface carrying limit of the automated equipment. - No historical context is associated after workflow execution, and previous session data cannot be reused from call results. Cause: The configured session identifier parameter is not carried in the HTTP request, causing the workflow to fail to match the corresponding context storage.
- A field missing error occurs when parsing the response, and the yield value cannot be extracted. Cause: The correct
Acceptrequest header is not specified, and the device returns unstructured text format instead of the preset JSON data.
How to Confirm the Configuration is Correct
- Send a single HTTP request, check that the response status code is
200 OK, and the response body contains preset fields such as device unique identifier and yield value. - Send two consecutive requests with an interval greater than the configured
request_interval, verify that the update timestamp of the second response is later than the first, confirming that the data update logic is working properly. - Call the workflow with the session identifier parameter, check that the workflow execution log contains context association records, confirming that the context is not lost.
- View the automated equipment's interface monitoring panel, confirm that the real-time request frequency does not exceed the preset
batch_request_limitthreshold.
