Coping Ordner in AmazonS3 Bucket (C#)

Question

Ich möchte einen Ordner mit allen vorhandenen Dateien in einen anderen Ordner in AmazonS3 gleichen Eimer kopieren.

Ich kann ein Objekt kopieren, aber was ich brauche ist, Ordner mit allen Dateien in einen anderen Ordner zu kopieren.

Answer 1

Hier ist das Beispiel, Ordner in AmazonS3 Bucket zu kopieren, die für mich funktioniert. Für weitere Informationen können Sie dies überprüfen link

public bool CopyFolderInsideS3Bucket(string source, string destination) 
     { 
      var strippedSource = source; 
      var strippedDestination = destination; 

      // process source 
      if (strippedSource.StartsWith("/")) 
       strippedSource = strippedSource.Substring(1); 
      if (strippedSource.EndsWith("/")) 
       strippedSource = source.Substring(0, strippedSource.Length - 1); 

      var sourceParts = strippedSource.Split('/'); 
      var sourceBucket = sourceParts[0]; 

      var sourcePrefix = new StringBuilder(); 
      for (var i = 1; i < sourceParts.Length; i++) 
      { 
       sourcePrefix.Append(sourceParts[i]); 
       sourcePrefix.Append("/"); 
      } 

      // process destination 
      if (strippedDestination.StartsWith("/")) 
       strippedDestination = destination.Substring(1); 
      if (strippedDestination.EndsWith("/")) 
       strippedDestination = destination.Substring(0, strippedDestination.Length - 1); 

      var destinationParts = strippedDestination.Split('/'); 
      var destinationBucket = destinationParts[0]; 

      var destinationPrefix = new StringBuilder(); 
      for (var i = 1; i < destinationParts.Length; i++) 
      { 
       destinationPrefix.Append(destinationParts[i]); 
       destinationPrefix.Append("/"); 
      } 

      var listObjectsResult = client.ListObjects(new ListObjectsRequest(){ 
       BucketName = sourceBucket, 
       Prefix = sourcePrefix.ToString(), 
       Delimiter = "/"}); 

      // copy each file 
      foreach (var file in listObjectsResult.S3Objects) 
      { 
       var request = new CopyObjectRequest(); 
       request.SourceBucket = Settings.BucketName; 
       request.SourceKey = file.Key; 
       request.DestinationBucket = destinationBucket; 
       request.DestinationKey = destinationPrefix + file.Key.Substring(sourcePrefix.Length); 
       request.CannedACL = S3CannedACL.PublicRead; 
       var response = (CopyObjectResponse)client.CopyObject(request); 
      } 

      // copy subfolders 
      foreach (var folder in listObjectsResult.CommonPrefixes) 
      { 
       var actualFolder = folder.Substring(sourcePrefix.Length); 
       actualFolder = actualFolder.Substring(0, actualFolder.Length - 1); 
       CopyFolderInsideS3Bucket(strippedSource + "/" + actualFolder, strippedDestination + "/" + actualFolder); 
      } 

      return true; 
     } 

Answer 2

Sie S3DirectoryInfo Klasse in der Amazon-Version 3.1.5 .net 3.5 diese Klasse copyTo Methode verwenden könnte.

habe ich die folgende Beispiel C# -Code von NTFS-Dateipfad 3.1.5 zu AmazonS3 mit C# .net 3.5 und amazon Version kopieren:

BasicAWSCredentials basicCredentials = new BasicAWSCredentials("your access key", "your secret key"); 
      AmazonS3Config configurationClient = new AmazonS3Config(); 
      configurationClient.RegionEndpoint = RegionEndpoint.EUCentral1; 
      try 
      { 
       using (AmazonS3Client clientConnection = new AmazonS3Client(basicCredentials, configurationClient)) 
       { 
        S3DirectoryInfo source = new S3DirectoryInfo(clientConnection, "sourcebucketname", "sourcefolderkey"); 
        S3DirectoryInfo target = new S3DirectoryInfo(clientConnection, "sourcebucketname", "destinationfolderkey"); 
        source.CopyTo(target); 

       } 
      } 
      catch(Exception ex) 
      { 

      }
