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

See more REST Examples

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.

Go

    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.

    gAuth := chilkat.NewAuthGoogle()
    // 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

    rest := chilkat.NewRest()

    // Connect using TLS.
    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
    xmlReqBody := chilkat.NewXml()
    xmlReqBody.SetTag("CreateBucketConfiguration")
    xmlReqBody.NewChild2("LocationConstraint","us")
    xmlReqBody.NewChild2("StorageClass","STANDARD")

    // Show the HTTP request body we'll be sending.
    fmt.Println(*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.
    responseStr := rest.FullRequestString("PUT","/",*xmlReqBody.GetXml())
    if rest.LastMethodSuccess() != true {
        fmt.Println(rest.LastErrorText())
        gAuth.DisposeAuthGoogle()
        rest.DisposeRest()
        xmlReqBody.DisposeXml()
        return
    }

    // Check the response status code to make sure it is 200.
    responseStatus := rest.ResponseStatusCode()
    fmt.Println("Response Status Code = ", responseStatus)
