func chilkatTest() {
    var success: Bool = false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let http = CkoHttp()!

    // Implements the following CURL command:

    // curl -X GET \
    //   https://your-webapp-hostname:your-webapp-port/v1/media/4b5bf27b-8672-4d55-bc21-d096dc200d0f \
    //   -H 'Authorization: Bearer your-auth-token' \
    //   -o path/filename

    // Use the following online tool to generate HTTP code from a CURL command
    // Convert a cURL Command to HTTP Source Code

    // Adds the "Authorization: Bearer your-auth-token" header.
    http.authToken = "your-auth-token"

    let bdResponseBody = CkoBinData()!
    success = http.quickGetBd(url: "https://your-webapp-hostname:your-webapp-port/v1/media/4b5bf27b-8672-4d55-bc21-d096dc200d0f", binData: bdResponseBody)
