(JavaScript) Send XML REST Request, Get Response with No Body (Google Cloud Storage)

Demonstrates sending a RESTful XML request, and receiving a response where the expected response is a header with no body (Content-Length = 0). This example will create a bucket in Google Cloud Storage using the Google Cloud Storage XML API.

See Create a Bucket using the XML API for additional request options.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example will create a bucket in Google Cloud Storage using the XML API.

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

var gAuth = new CkAuthGoogle();
// Obtain an access token as shown in one of the following examples:
// See Get Access Token using a Service Account JSON Key
// See Get Access Token using a P12 File

var rest = new CkRest();

// Connect using TLS.
var bAutoReconnect = true;
success = rest.Connect("www.googleapis.com",443,true,bAutoReconnect);

// Provide the authentication credentials (i.e. the access key)
success = rest.SetAuthGoogle(gAuth);

// Build the XML request body for creating a bucket.
// See https://cloud.google.com/storage/docs/xml-api/put-bucket-create
var xmlReqBody = new CkXml();
xmlReqBody.Tag = "CreateBucketConfiguration";
xmlReqBody.NewChild2("LocationConstraint","us");
xmlReqBody.NewChild2("StorageClass","STANDARD");

// Show the HTTP request body we'll be sending.
console.log(xmlReqBody.GetXml());

// There are no query parameters...

// The HOST header must be specified, because it needs to be different than
// the domain previously passed to the Connect method.
// The name of the bucket is the 1st part of the HOST header.
success = rest.AddHeader("Host","chilkat-example-bucket.storage.googleapis.com");

// The project ID is specified in an HTTP request header
success = rest.AddHeader("x-goog-project-id","chilkattest-1050");

// In this case, the response body is expected to be empty.  We can still
// call FullRequestString.  We expect an empty string to be returned.
var responseStr = rest.FullRequestString("PUT","/",xmlReqBody.GetXml());
if (rest.LastMethodSuccess !== true) {
    console.log(rest.LastErrorText);
    return;
}

// Check the response status code to make sure it is 200.
var responseStatus = rest.ResponseStatusCode;
console.log("Response Status Code = " + responseStatus);
