Rust

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

// Use the Chilkat Email API to create or load an email.
let email = chilkat::Email::new();
email.set_subject("This is a test GMail email created using Chilkat.");
email.set_charset("utf-8");
let _ = email.add_plain_text_alternative_body("This is a test");
let _ = email.add_html_alternative_body("<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 sb_mime = chilkat::StringBuilder::new();
let _ = email.get_mime_sb(&sb_mime);
let _ = sb_mime.encode("base64url", "utf-8");

// The body of the HTTP request will be JSON..
let json = chilkat::JsonObject::new();
let _ = json.update_sb("message.raw", &sb_mime);

// Upload the email to GMail as a draft.
let http = chilkat::Http::new();
http.set_auth_token("GMAIL-ACCESS-TOKEN");

let url = "https://www.googleapis.com/gmail/v1/users/me/drafts".to_string();
let resp = chilkat::HttpResponse::new();
if http.http_json("POST", &url, &json, "application/json", &resp).is_err() {
    println!("{}", http.last_error_text());
    return;
}

// A status code of 200 indicates success.
println!("Response status code: {}", resp.status_code());
println!("Response body:");
println!("{}", resp.body_str());

// 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"
//   ]
//  }
// }
