Python 3 Boto 3、AWS S3:获取对象 URL [英] Python 3 Boto 3, AWS S3: Get object URL

问题描述

我需要在上传文件后直接检索公共对象 URL，以便能够将其存储在数据库中.这是我的上传代码:

I need to retrieve an public object URL directly after uploading a file, this to be able to store it in a database. This is my upload code:

   s3 = boto3.resource('s3')
   s3bucket.upload_file(filepath, objectname, ExtraArgs={'StorageClass': 'STANDARD_IA'})

我不是在寻找预先签名的 URL，而是始终可以通过 https 公开访问的 URL.

I am not looking for a presigned URL, just the URL that always will be publicly accessable over https.

感谢任何帮助.

推荐答案

没有简单的方法，但是您可以从存储桶所在的区域 (get_bucket_location)、存储桶名称和存储密钥:

There's no simple way but you can construct the URL from the region where the bucket is located (get_bucket_location), the bucket name and the storage key:

bucket_name = "my-aws-bucket"
key = "upload-file"

s3 = boto3.resource('s3')
bucket = s3.Bucket(bucket_name)
bucket.upload_file("upload.txt", key)
location = boto3.client('s3').get_bucket_location(Bucket=bucket_name)['LocationConstraint']
url = "https://s3-%s.amazonaws.com/%s/%s" % (location, bucket_name, key)
