(Xojo Plugin) 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.

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

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

Dim gAuth As New Chilkat.AuthGoogle
// 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

Dim rest As New Chilkat.Rest

// Connect using TLS.
Dim bAutoReconnect As Boolean
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

System.DebugLog(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.
Dim responseStr As String
responseStr = rest.FullRequestString("PUT","/",xmlReqBody.GetXml())

    System.DebugLog(rest.LastErrorText)

End If
