如何使用 AWS C++ 开发工具包在给定的开始和结束日期范围内列出 S3 中的文件

我找不到任何方法或示例代码来列出在给定日期范围内创建的S3文件。我试过WithIfModifiedSince、SetIfModifiedSince和GetObjectRequest。

#include <aws/core/Aws.h>
#include <aws/s3/S3Client.h>
#include <aws/s3/model/ListObjectsRequest.h>
#include <aws/s3/model/Object.h>
/* list_files_s3_create_withen_given_date_range */
{
Aws::S3::S3Client s3_client;
Aws::S3::Model::ListObjectsRequest objects_request;
objects_request.WithBucket(bucket_name);
/* This lists all the files in s3 bucket. */
/* But how to get files within a given date range. */
//Aws::S3::Model::GetObjectRequest object_request;
//object_request.SetBucket(bucket_name);
//object_request.WithIfModifiedSince(DateTime)
auto list_objects_outcome = s3_client.ListObjects(objects_request);
if (list_objects_outcome.IsSuccess())
{
Aws::Vector<Aws::S3::Model::Object> object_list =
list_objects_outcome.GetResult().GetContents();
for (auto const &s3_object : object_list)
{
std::cout << "* " << s3_object.GetKey() << std::endl;
}
}
}    

//------------------------------------

Aws::Utils::DateTime startdt = Aws::Utils::DateTime::DateTime("2019-10-23T10:00:00Z", Aws::Utils::DateFormat::ISO_8601); 
Aws::Utils::DateTime enddt = Aws::Utils::DateTime::Now(); Aws::S3::Model::GetObjectRequest object_request; object_request.SetBucket(bucket_name); object_request.WithIfModifiedSince(startdt); 
//object_request.SetIfModifiedSince(startdt); 
auto object_outcome = s3_client.GetObject(objects_request);
if (object_outcome.IsSuccess())
{
std::cout << object_outcome.GetResultWithOwnership().GetETag() << std::endl;
}

The code is not returning any object(file) from s3 bucket why ?
