S3 - Working with Buckets in a Region

See more Amazon S3 (new) Examples

Demonstrates how to work with S3 buckets located in a particular region. Go

    success := false

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

    // When usig the REST class to access an S3 bucket that has been created in a particular region,
    // there are three important things to remember:
    // 
    // 1) Connect to the domain that includes the region.  For example, instead of connecting to
    //    "s3.amazonaws.com", connect to "s3.eu-central-1.amazonaws.com" if your bucket is in the EU Frankfurt region.
    //    See http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region   for a list of S3 region domains (endpoints)
    // 
    // 2) Set the AuthAws.Region property equal to the region, such as "eu-central-1".
    // 
    // 3) Include the region in request's Host header.
    // 

    // This example will upload to a bucket in the eu-central-1 region.
    // 
    rest := chilkat.NewRest()

    // Connect to the Amazon AWS REST server.
    bTls := true
    port := 443
    bAutoReconnect := true
    success = rest.Connect("s3.eu-central-1.amazonaws.com",port,bTls,bAutoReconnect)

    // Provide AWS credentials for the REST call.
    authAws := chilkat.NewAuthAws()
    authAws.SetAccessKey("AWS_ACCESS_KEY")
    authAws.SetSecretKey("AWS_SECRET_KEY")
    authAws.SetServiceName("s3")
    authAws.SetRegion("eu-central-1")
    success = rest.SetAuthAws(authAws)

    // Set the bucket name via the HOST header.
    // In this case, the bucket name is "chilkateufrankfurt" (which was created in the eu-central-1 region)
    rest.SetHost("chilkateufrankfurt.s3.eu-central-1.amazonaws.com")

    fileData := chilkat.NewBinData()
    success = fileData.LoadFile("qa_data/jpg/starfish.jpg")

    // Upload the file to Amazon S3.
    responseBody := chilkat.NewStringBuilder()
    success = rest.FullRequestBd("PUT","/starfish.jpg",fileData,responseBody)
