我正在尝试使用 AWS cognito 服务对文件进行身份验证和上传。我已获得我的区域类型、身份池、AWS 账户 ID 和 UnAuthRole。我也知道生产和开发存储桶的名称。
我想我正在设置 AWS 访问密钥和 AWS 私有密钥...我想使用 cognito 进行身份验证,并使用结果允许我执行存储桶列表,然后上传文件。
我做错了什么?如何使用认知 ID 建立 S3 连接?
这是我的代码和由此产生的错误:
#!/usr/bin/python
import boto3
import boto
#boto.set_stream_logger('foo')
import json
client = boto3.client('cognito-identity','us-east-1')
resp = client.get_id(AccountId='<ACCNTID>',IdentityPoolId='<IDPOOLID>')
print "nIdentity ID: %s"%(resp['IdentityId'])
print "nRequest ID: %s"%(resp['ResponseMetadata']['RequestId'])
resp = client.get_open_id_token(IdentityId=resp['IdentityId'])
token = resp['Token']
print "nToken: %s"%(token)
print "nIdentity ID: %s"%(resp['IdentityId'])
resp = client.get_credentials_for_identity(IdentityId=resp['IdentityId'])
secretKey = resp['Credentials']['SecretKey']
accessKey = resp['Credentials']['AccessKeyId']
print "nSecretKey: %s"%(secretKey)
print "nAccessKey ID: %s"%(accessKey)
print resp
conn = boto.connect_s3(aws_access_key_id=accessKey,aws_secret_access_key=secretKey,debug=0)
print "nConnection: %s"%(conn)
for bucket in conn.get_all_buckets():
print bucket.name
错误:
Traceback (most recent call last):

这个相应的iOS代码工作正常:
AWSCognitoCredentialsProvider *credentialsProvider =
[AWSCognitoCredentialsProvider credentialsWithRegionType:awsCognitoRegionType
accountId:awsAccountId
identityPoolId:awsCognitoIdentityPool
unauthRoleArn:unauthRoleArn
authRoleArn:nil];
AWSServiceConfiguration *configuration = [AWSServiceConfiguration configurationWithRegion:awsCognitoRegionType
credentialsProvider:credentialsProvider];
....
AWSS3TransferManagerUploadRequest *uploadRequest = [AWSS3TransferManagerUploadRequest new];
uploadRequest.bucket = [ELEEnvironment currentEnvironment].userDataS3Bucket;
uploadRequest.key = key;
uploadRequest.body = uploadFileURL;
[[self uploadTask:uploadRequest] continueWithExecutor:[BFExecutor mainThreadExecutor]...
感谢您的任何帮助!
这个问题确实无效,因为身份验证失败不是在创建会话时,而是在尝试列出存储桶时。
从特定存储桶上传和下载适用于上述代码,但不能列出所有存储桶。
# Upload a new file
data = open('test.jpg', 'rb')
s3.Bucket('mybucket').put_object(Key='test.jpg', Body=data)
# S3 Object
obj = s3.Object(bucket_name='mybucket', key='test.jpg')
response = obj.get()
data = response['Body'].read()
print len(data)
PhilBot,我不知道为什么您的原始代码示例使用 boto(而不是 boto3)连接到 s3。 该代码使用 boto3 连接到认知。 截至目前,boto3 是稳定的,可能没有太多理由再使用 boto。 (也许当你最初发布你的问题时,boto3并不像今天这样稳定。
当我尝试使用您的代码通过 boto3 连接到 kinesis 时,它不起作用——我不得不将响应["凭据"]["会话令牌"] 作为 client() 函数的aws_session_token传递。
你的错误:
File "./test.py", line 32, in <module>
bucket = conn.get_bucket("elektradevbucket")
这是引用存储桶的代码部分:
bucket = conn.get_bucket("testbucket")
'''
s3 = boto3.resource('s3')
for bucket in s3.buckets.all():
print(bucket.name)
s3.Bucket('testbucket')
是否确实正在运行或调用了正确的脚本?
最好-尤利安
