    email.AddPlainTextAlternativeBody("This is a test")
    email.AddHtmlAlternativeBody("<html><body><p>This is a <b>test</b></body></html>")

    // We'll need to get the full MIME of the email encoded to a base64url string.
    let sbMime = CkoStringBuilder()
    email.GetMimeSb(sbMime)
    sbMime.Encode("base64url", charset: "utf-8")

    // The body of the HTTP request will be JSON..
    let json = CkoJsonObject()
    json.UpdateSb("message.raw", sb: sbMime)

    // Upload the email to GMail as a draft.
    let http = CkoHttp()
    http.AuthToken = "GMAIL-ACCESS-TOKEN"

    var url: String? = "https://www.googleapis.com/gmail/v1/users/me/drafts"
    var resp: CkoHttpResponse? = http.PostJson3(url, contentType: "application/json", json: json)
    if http.LastMethodSuccess != true {
        print("\(http.LastErrorText)")
        return
    }

    // A status code of 200 indicates success.
    print("Response status code: \(resp!.StatusCode.intValue)")
    print("Response body:")
    print("\(resp!.BodyStr)")
    resp = nil

    // The response body contains JSON.
    // Use the online tool at Generate JSON Parsing Code
    // to generate JSON parsing code.

    // A sample successful JSON response:

    // {
    //  "id": "r-2607584557788895307",
    //  "message": {
    //   "id": "166f09932c662e93",
    //   "threadId": "166f09932c662e93",
    //   "labelIds": [
    //    "DRAFT"
    //   ]
    //  }
    // }
