Demonstrates a file upload to Google Drive where the contents of the file are contained in a string variable. Go

    success := false

    // This example will upload a file to Google Drive.
    success = true

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

    // See Get Access Token using a Service Account JSON Key
    // See Get Access Token using a P12 File

    // Connect using TLS.

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

    // A multipart upload to Google Drive needs a multipart/related Content-Type
