If you need to rename a file within a Bucket, you can use the CopyObject interface to copy the source object to the target object, and then use the DeleteObject interface to remove the source object.
Rename a single object
The following code is used to rename the object src-object to dest-object within the storage bucket.
using System;
using TOS;
using TOS.Error;
using TOS.Model;
namespace ConsoleApp
{
internal class Program
{
private static void Main(string[] args)
{
var ak = Environment.GetEnvironmentVariable("TOS_ACCESS_KEY");
var sk = Environment.GetEnvironmentVariable("TOS_SECRET_KEY");
var endpoint = "https://tos-cn-beijing.volces.com";
var region = "cn-beijing";
var bucketName = "*** Provide your bucket name ***";
var srcObjectKey = "src-object";
var dstObjectKey = "dest-object";
var client = TosClientBuilder.Builder().SetAk(ak).SetSk(sk).SetEndpoint(endpoint).SetRegion(region).Build();
try
{
var copyObjectInput = new CopyObjectInput()
{
Bucket = bucketName,
Key = dstObjectKey,
SrcBucket = bucketName,
SrcKey = srcObjectKey,
};
var copyObjectOutput = client.CopyObject(copyObjectInput);
Console.WriteLine("CopyObject succeeded, request id {0}", copyObjectOutput.RequestID);
var deleteObjectInput = new DeleteObjectInput()
{
Bucket = bucketName,
Key = srcObjectKey
};
var deleteObjectOutput = client.DeleteObject(deleteObjectInput);
Console.WriteLine("DeleteObject succeeded, request id {0}", deleteObjectOutput.RequestID);
}
catch (TosServerException ex)
{
Console.WriteLine("CopyObject failed, request id {0}", ex.RequestID);
Console.WriteLine("CopyObject failed, status code {0}", ex.StatusCode);
Console.WriteLine("CopyObject failed, response error code {0}", ex.Code);
Console.WriteLine("CopyObject failed, response error message {0}", ex.Message);
}
catch (TosClientException ex)
{
Console.WriteLine("CopyObject failed, error message {0}", ex.Message);
}
catch (Exception ex)
{
Console.WriteLine("CopyObject failed, {0}", ex.Message);
}
}
}
}
Rename Directory
The following code is used to rename the exampledir1/ directory in the storage bucket to exampledir2/.
using System;
using TOS;
using TOS.Error;
using TOS.Model;
namespace ConsoleApp
{
internal class Program
{
private static void Main(string[] args)
{
var ak = Environment.GetEnvironmentVariable("TOS_ACCESS_KEY");
var sk = Environment.GetEnvironmentVariable("TOS_SECRET_KEY");
var endpoint = "https://tos-cn-beijing.volces.com";
var region = "cn-beijing";
var bucketName = "*** Provide your bucket name ***";
var oldPrefix = "exampledir1/";
var newPrefix = "exampledir2/";
var client = TosClientBuilder.Builder().SetAk(ak).SetSk(sk).SetEndpoint(endpoint).SetRegion(region).Build();
try
{
var truncated = true;
var marker = "";
while (truncated)
{
var listObjectsInput = new ListObjectsInput()
{
Bucket = bucketName,
MaxKeys = 1000,
Marker = marker,
Prefix = oldPrefix
};
var listObjectsOutput = client.ListObjects(listObjectsInput);
foreach (var obj in listObjectsOutput.Contents)
{
var newKey = newPrefix + obj.Key.Substring(oldPrefix.Length);
var copyObjectInput = new CopyObjectInput()
{
Bucket = bucketName,
Key = newKey,
SrcBucket = bucketName,
SrcKey = obj.Key
};
var copyObjectOutput = client.CopyObject(copyObjectInput);
Console.WriteLine("CopyObject succeeded, request id {0}", copyObjectOutput.RequestID);
var deleteObjectInput = new DeleteObjectInput()
{
Bucket = bucketName,
Key = obj.Key
};
var deleteObjectOutput = client.DeleteObject(deleteObjectInput);
Console.WriteLine("DeleteObject succeeded, request id {0}", deleteObjectOutput.RequestID);
}
truncated = listObjectsOutput.IsTruncated;
marker = listObjectsOutput.NextMarker;
}
}
catch (TosServerException ex)
{
Console.WriteLine("CopyObject failed, request id {0}", ex.RequestID);
Console.WriteLine("CopyObject failed, status code {0}", ex.StatusCode);
Console.WriteLine("CopyObject failed, response header {0}", ex.Header);
Console.WriteLine("CopyObject failed, response error code {0}", ex.Code);
Console.WriteLine("CopyObject failed, response error message {0}", ex.Message);
}
catch (TosClientException ex)
{
Console.WriteLine("CopyObject failed, error message {0}", ex.Message);
}
catch (Exception ex)
{
Console.WriteLine("CopyObject failed, {0}", ex.Message);
}
}
}
}
