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.

Swift

func chilkatTest() {
    var success: Bool = false

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

    let rest = CkoRest()!

    // Connect to the Amazon AWS REST server in the desired region.
    var bTls: Bool = true
    var port: Int = 443
    var bAutoReconnect: Bool = true
    success = rest.connect(hostname: "s3-us-west-2.amazonaws.com", port: port, tls: bTls, autoReconnect: bAutoReconnect)

    // Provide AWS credentials.
    let authAws = CkoAuthAws()!
    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(authProvider: 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(name: "x-amz-copy-source", value: "/chilkat.qa/images/sea_creatures/starfish.jpg")

    let sbResponse = CkoStringBuilder()!
    success = rest.fullRequestNoBodySb(httpVerb: "PUT", uriPath: "/images/sea_creatures/starfish3.jpg", sb: sbResponse)
    if success == false {
        print("\(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.intValue != 200 {
        // Examine the request/response to see what happened.
        print("response status code = \(rest.responseStatusCode.intValue)")

    print("\(sbResponse.getAsString()!)")
    print("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(name: "x-amz-copy-source")

    success = rest.fullRequestNoBodySb(httpVerb: "DELETE", uriPath: "/images/sea_creatures/starfish.jpg", sb: sbResponse)

        print("\(rest.lastErrorText!)")
        return

    var statusCode: Int = rest.responseStatusCode.intValue
    print("Response status code = \(statusCode)")
    print("Response text = ")
    print("\(sbResponse.getAsString()!)")
