我正在尝试使用 AWS cognito 服务来验证和上传文件。我已获得我的 regionType、identityPool、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 密钥...我想使用 cognito 进行身份验证并使用结果来允许我进行存储桶列表,然后再上传文件。
我究竟做错了什么?如何使用 cognito id 建立 S3 连接?
这是我的代码和产生的错误:
#!/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 代码可以正常工作:
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]...
谢谢你的帮助!
