S3 Find Bucket Region

See more Amazon S3 (new) Examples

Demonstrates how to find out the region of an S3 bucket. Swift

func chilkatTest() {
    var success: Bool = false

    // This 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 using the correct region (in this example, "us-west-2")
    var bTls: Bool = true
    var port: Int = 443
    var bAutoReconnect: Bool = true
    success = rest.connect(hostname: "s3.amazonaws.com", port: port, tls: bTls, autoReconnect: bAutoReconnect)

    // Provide AWS credentials for the REST call.
    let authAws = CkoAuthAws()!
    authAws.accessKey = "AWS_ACCESS_KEY"
    authAws.secretKey = "AWS_SECRET_KEY"
    authAws.serviceName = "s3"
    success = rest.setAuthAws(authProvider: authAws)

    // The bucket name we want to know about is set in the HOST header.
    // In this example, we want to find the region for the "chilkat.qa" bucket.
    rest.host = "chilkat.qa.s3.amazonaws.com"

    // Send the GET request to query the bucket location.
    var strResult: String? = rest.fullRequestNoBody(httpVerb: "GET", uriPath: "/?location")
    if rest.lastMethodSuccess != true {
        print("\(rest.lastErrorText!)")
        return
    }

    var responseStatusCode: Int = rest.responseStatusCode.intValue
    print("Response status code = \(responseStatusCode)")
    if responseStatusCode != 200 {
        print("\(rest.responseHeader!)")
        print("\(strResult!)")
        print("Failed.")
        return
    }

    print("\(strResult!)")

    // The result contains XML like this:
    // <?xml version="1.0" encoding="UTF-8"?>
    // <LocationConstraint xmlns="http://s3.amazonaws.com/doc/2006-03-01/">us-west-2</LocationConstraint>

    // Get the "us-west-2" from the XML
    let xml = CkoXml()!
    success = xml.load(xmlData: strResult)
    print("region = \(xml.content!)")
