Querying API Calls Within a Period

Function

This API is used to query the number of API calling times based on the API ID and specified time period. A sample value is returned every minute. If the query scope is within one hour, a sample value is returned every minute, which is the accumulated value within one minute. For security purposes, run the curl command on the server to query information, and then clear operation records, including but not limited to records in the ~/.bash_history and /var/log/messages directories (if any).
