Boto + Python + AWS S3：如何獲取特定文件的last_modified屬性？

Question

很可能得到LAST_MODIFIED屬性：

import boto3 

s3 = boto3.resource('s3') 

bucket_name = 'bucket-one' 
bucket = s3.Bucket(bucket_name) 

for obj in bucket.objects.all(): 
    print obj.last_modified 

但它在一個桶中的所有對象這樣做。我如何獲得桶下一個特定對象/文件的last_modified屬性？

Answer 1

bucket_name = 'bucket-one' 
file_name = 'my_file' 

object = s3.Object(bucket_name, file_name) 
print object.last_modified 

或者乾脆：

print s3.Object(bucket_name, file_name).last_modified 

Answer 2

希望這有助於你....

這將讓特定對象的最後修改時間在S3存儲桶

import boto3 
import time 
from pprint import pprint 

s3 = boto3.resource('s3',region_name='S3_BUCKET_REGION_NAME') 
bucket='BUCKET_NAME' 
key='OBJECT_NAME' 
summaryDetails=s3.ObjectSummary(bucket,key) 
timeFormat=summaryDetails.last_modified 
formatedTime=timeFormat.strftime("%Y-%m-%d %H:%M:%S") 
pprint('Bucket name is '+ bucket + ' and key name is ' + key + ' and last modified at time '+ formatedTime) 

謝謝....
