Python使用boto3操作AWS S3

1、登录aws中国，选择s3服务

2、可以创建一个bucket，也可以用create_bucket接口

3、使用boto3获取bucket列表session = Session(aws_access_ke鲻戟缒男y_id=aws_key, aws_secret_a艘早祓胂ccess_key=aws_secret, region_name='cn-north-1')s3 = session.resource('s3')for bucket in s3.buckets.all(): print('bucket name:%s'%bucket.name)

4、将本地文件传到s3的指定bucket中data = open('nj.png', 'rb')file_obj = s3.Bucket(bucket).put_object(Key=objkey, Body=data)

5、获取URLdown_url = client.generate_presigned_url( 'g髫潋啜缅et_object', Params={'Bucket': bucket, 'Key': objkey}, ExpiresIn= 3600)

6、获取bucket中对象列表bucket = s3.Bucket('predictionimage')for obj in bucket.objects.all(): print(obj.key)
