    email.addPlainTextAlternativeBody("This is a test")

    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"
    //   ]
    //  }
    // }
