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

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

// Provide AWS credentials for the REST call.
Chilkat.AuthAws authAws = new Chilkat.AuthAws();
authAws.AccessKey = "AWS_ACCESS_KEY";
authAws.SecretKey = "AWS_SECRET_KEY";
authAws.ServiceName = "s3";
authAws.Region = "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.Host = "chilkateufrankfurt.s3.eu-central-1.amazonaws.com";

Chilkat.BinData fileData = new Chilkat.BinData();
success = fileData.LoadFile("qa_data/jpg/penguins.jpg");

// Upload the file to Amazon S3.
Chilkat.StringBuilder responseBody = new Chilkat.StringBuilder();
success = rest.FullRequestBd("PUT","/penguins.jpg",fileData,responseBody);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// Did we get a 200 response indicating success?
int statusCode = rest.ResponseStatusCode;
if (statusCode != 200) {
    Debug.WriteLine("Error response: " + responseBody.GetAsString());
    Debug.WriteLine("Status code: " + Convert.ToString(statusCode) + ", Status text: " + rest.ResponseStatusText);
    return;
}

Debug.WriteLine("File successfully uploaded.");
