我试图从 s3 存储桶中获取最后修改的文件。我尝试了不同的方法来检索它。但它总是向我显示目录中的所有文件。有人可以请教吗？

 def last_updated_file(self):
    bucket_name = "test-bucket"
    conn = boto3.session.Session(profile_name="profile-name")
    s3 = conn.resource('s3')
    test_buc = s3.Bucket(bucket_name)
    for x in test_buc.objects.filter(Prefix='test-file/files/'):
        result = x.last_modified
        print("Result is :", result)

我得到的输出是

Result is : 2022-01-18 15:52:48+00:00
Result is : 2022-01-18 15:54:11+00:00
Result is : 2022-01-18 15:54:12+00:00
Result is : 2022-01-24 17:40:24+00:00

我只需要最后一个文件“2022-01-24 17:40:24+00:00”

def last_updated_file(self):

conn = boto3.session.Session(profile_name="profile-name")
s3 = conn.resource('s3')
test_buc = s3.Bucket(bucket_name)
x = None
for x in test_buc.objects.filter(Prefix='test-file/files/'):
    result = x.last_modified
    print("Result is :", result)
last_modified_file = x.last_modified

这样我们就可以得到最后更新的文件
