当我简单地运行下面的代码时,我总是得到这个错误。

s3 = boto3.resource('s3')
bucket_name = "python-sdk-sample-%s" % uuid.uuid4()
print("Creating new bucket with name:", bucket_name)
s3.create_bucket(Bucket=bucket_name)

我已将我的证书文件保存在

C:\Users\myname\.aws\证书,从那里Boto应该读我的证书。

我的设置错了吗?

下面是boto3的输出。set_stream_logger (botocore,级别=“调试”)。

这些指令适用于具有AWS单一用户配置文件的windows机器。确保你的~/。Aws /凭证文件如下所示

[profile_name]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey

我必须将AWS_DEFAULT_PROFILEenvironment变量设置为在凭据中找到的profile_name。 然后我的蟒蛇就能连接了。从这里开始

import boto3

# Let's use Amazon S3
s3 = boto3.resource('s3')

# Print out bucket names
for bucket in s3.buckets.all():
    print(bucket.name)

其他回答

确保你的~/。Unix中的aws/credentials文件是这样的:

[MyProfile1]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey

[MyProfile2]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey

你的Python脚本应该是这样的,它可以工作:

from __future__ import print_function
import boto3
import os

os.environ['AWS_PROFILE'] = "MyProfile1"
os.environ['AWS_DEFAULT_REGION'] = "us-east-1"

ec2 = boto3.client('ec2')

# Retrieves all regions/endpoints that work with EC2
response = ec2.describe_regions()
print('Regions:', response['Regions'])

导出证书也可以,在linux:

export AWS_SECRET_ACCESS_KEY="XXXXXXXXXXXX"
export AWS_ACCESS_KEY_ID="XXXXXXXXXXX"

如果您确定正确配置了aws,只需确保项目的用户可以从./aws读取数据,或者只是以根用户身份运行项目

我是这样解决这个问题的:

aws configure

之后我手动输入:

AWS Access Key ID [None]: xxxxxxxxxx
AWS Secret Access Key [None]: xxxxxxxxxx
Default region name [None]: us-east-1
Default output format [None]: just hit enter

从那以后,它对我起作用了

boto3在文件夹中查找凭据,例如

C:\ProgramData\Anaconda3\envs\tensorflow\Lib\site-packages\botocore\.aws

您应该在这个文件夹中保存两个文件凭证和配置。

您可能希望查看boto3在此链接中搜索凭据的一般顺序。在配置凭据子标题下查看。
