使用grails的AWS S3

我想建立連接到aws以在s3存儲桶上執行基本操作。以下是代碼：使用grails的AWS S3

def list(){ 
     AWSCredentials credentials = new BasicAWSCredentials("Access key", "Secret Key"); 


     AmazonS3 s3client = new AmazonS3Client(credentials); 


     String bucketName = "sample-bucket-from-java-code"; 



     System.out.println("Listing all buckets : "); 
     for (Bucket bucket : s3client.listBuckets()) { 
      System.out.println(" - " + bucket.getName()); 
     } 
    }

這給我的錯誤：

request- Received error response: com.amazonaws.services.s3.model.AmazonS3Exception: The request signature we calculated does not match the signature you provided. Check your key and signing method.

我也雙重檢查，我使用的訪問密鑰和祕密密鑰。無法找出問題。

你有沒有檢查http://stackoverflow.com/questions/2777078/amazon-mws-request-signature-calculated-does-not-match-the-signature-provided –

它總是很好用「cognito accountId」而不是訪問和密鑰。因爲使用cognito accountID限制了對AWS的訪問權限，可以隨時更改。

//初始化Amazon Cognito憑據提供程序。

AWSCognitoCredentialsProvider* credentialsProvider = [AWSCognitoCredentialsProvider 
                 credentialsWithRegionType:AWSRegionUSEast1 
                 accountId:@"xxxxxxxxxxx" 
                 identityPoolId:@"xxxxxxxxxxx" 
                 unauthRoleArn:@"arn:aws:iam::xxxxxxxxxxx" 
                 authRoleArn:nil]; 

AWSServiceConfiguration* configuration = [AWSServiceConfiguration configurationWithRegion:AWSRegionUSWest2 
                     credentialsProvider:credentialsProvider]; 

[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

您還可以從我的博客中找到運行代碼。

不要忘記添加憑據信息：

帳戶ID：@「XXXXXXXX」 identityPoolId：@」 XXXXXXXX-XXXXXXXX」 unauthRoleArn：@」 XXXXXXXX-XXXXXXXX-XXXXXXXX-XXXXXXXX「

IAM的用戶和角色是一樣靈活，和通常是在這種情況下使用的。 –

@tauheed剛剛提供了另一種選擇。同意馬克！ –
