以下不起作用:
来自boto 3 docs:
http://boto3.readthedocs.io/en/latest/guide/s3.html#generating-presigned-urls
这是我的带有占位符存储桶和键值的脚本:
import boto3
import requests
from botocore.client import Config
# Get the service client.
s3 = boto3.client('s3', config=Config(signature_version='s3v4'))
# Generate the URL to get 'key-name' from 'bucket-name'
url = s3.generate_presigned_url(
ClientMethod='get_object',
Params={
'Bucket': 'mybucketname',
'Key': 'myObject.txt'
}
)
print url
response = requests.get(url)
print response
S3以403:

您需要为boto3客户端提供aws凭据。 Docs here
如果您需要获取有关访问凭据的帮助,可以查看here。
import boto3
client = boto3.client(
's3',
aws_access_key_id=ACCESS_KEY,
aws_secret_access_key=SECRET_KEY,
aws_session_token=SESSION_TOKEN,
)
# Or via the Session
session = boto3.Session(
aws_access_key_id=ACCESS_KEY,
aws_secret_access_key=SECRET_KEY,
aws_session_token=SESSION_TOKEN,
)
