You can enable access logs to record bucket access to log files, which are stored in a specified bucket.
The log file format is as follows:
<TargetPrefix><SourceBucket>YYYY-mm-DD-HH-MM-SS-UniqueString
For more information about access log files, see Set access logging.
Enable access logging
Run the following code to enable bucket access logging:
#include "oss_api.h"
#include "aos_http_io.h"
const char *endpoint = "<yourEndpoint>";
const char *access_key_id = "<yourAccessKeyId>";
const char *access_key_secret = "<yourAccessKeySecret>";
const char *bucket_name = "<yourBucketName>";
const char *target_bucket_name = "<yourTargetBucketName>";
const char *target_logging_prefix = "<yourTargetPrefix>";
