S3 Rename File

See more Amazon S3 (new) Examples

Demonstrates how to rename a file on Amazon S3.

Renaming an object (file) in AWS S3 using the AWS S3 API involves copying the object to a new location with the desired name and then deleting the original object.

.NET Core C#

bool success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Rest rest = new Chilkat.Rest();

// Connect to the Amazon AWS REST server in the desired region.
bool bTls = true;
int port = 443;
bool bAutoReconnect = true;
success = rest.Connect("s3-us-west-2.amazonaws.com",port,bTls,bAutoReconnect);

// Provide AWS credentials.
Chilkat.AuthAws authAws = new Chilkat.AuthAws();
authAws.AccessKey = "AWS_ACCESS_KEY";
authAws.SecretKey = "AWS_SECRET_KEY";
authAws.ServiceName = "s3";

// This particular bucket is in the Oregon region, as opposed to the US Standard,
// therefore the Region must be set appropriately.
// Also note that we connected to "s3-us-west-2.amazonaws.com".
authAws.Region = "us-west-2";

rest.SetAuthAws(authAws);

// Set the bucket name via the HOST header.
// In this case, the bucket name is "chilkat.qa".
// Note that the Host header should use "bucketName.s3.amazonaws.com", not "bucketName.s3-us-west-2.amazonaws.com"
rest.Host = "chilkat.qa.s3.amazonaws.com";

// Copy /images/sea_creatures/starfish.jpg to /images/sea_creatures/starfish3.jpg
// Notice here that the x-amz-copy-source includes the bucket in the source path,
// but the target path passed to FullRequestNoBody does NOT contain the bucket (because the bucket
// was already specified in the Host header).
rest.AddHeader("x-amz-copy-source","/chilkat.qa/images/sea_creatures/starfish.jpg");

Chilkat.StringBuilder sbResponse = new Chilkat.StringBuilder();
success = rest.FullRequestNoBodySb("PUT","/images/sea_creatures/starfish3.jpg",sbResponse);
if (success == false) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// When successful, the S3 Storage service will respond with a 200 or 204 response code,
// with an XML body.  
if (rest.ResponseStatusCode != 200) {
    // Examine the request/response to see what happened.
    Debug.WriteLine("response status code = " + Convert.ToString(rest.ResponseStatusCode));

Debug.WriteLine(sbResponse.GetAsString());
Debug.WriteLine("Copy Successful.");

// --------------------------------------
// Now we can delete the original file..
// --------------------------------------

// We no longer want to send the x-amz-copy-source header.  Remove it.
rest.RemoveHeader("x-amz-copy-source");

success = rest.FullRequestNoBodySb("DELETE","/images/sea_creatures/starfish.jpg",sbResponse);
if (success == false) {
    Debug.WriteLine(rest.LastErrorText);
