See more Yahoo Mail Examples

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

// See Get Yahoo Mail OAuth2 Access Token for Desktop App 
// for sample code showing how to obtain a Yahoo Mail access token.

// In this example, our access token was previously saved to the following file which contains JSON like this:
// {
//   "access_token": "kCVQdnOdul...LHucA--",
//   "refresh_token": "AIenVXETSo0jklFBVkPS8vVm8E.Ej9ToRG.xDbDYmZ65WIs5t6CZhDrD",
//   "expires_in": 3600,
//   "token_type": "bearer",
//   "xoauth_yahoo_guid": "HGDQCVF5JB4YDOWHITQJFBHCWA"
// }

var json = new CkJsonObject();
success = json.LoadFile("qa_data/tokens/yahooMail.json");
if (success !== true) {
    console.log("Failed to load GMail access token file.");
    return;
}

var accessToken = json.StringOf("access_token");

// Do OAuth2 authentication by using the access token as the password in the Login method below...
var imap = new CkImap();

imap.Ssl = true;
imap.Port = 993;

// Connect to the Yahoo IMAP server.
success = imap.Connect("imap.mail.yahoo.com");
if (success == false) {
    console.log(imap.LastErrorText);
    return;
}

// Indicate that XOAUTH2 authentication is to be used:
imap.AuthMethod = "XOAUTH2";

// Login
// Use the email address of the GMail account that granted authorization.
success = imap.Login("user@yahoo.com",accessToken);
if (success !== true) {
    console.log(imap.LastErrorText);
}
else {
    console.log("Successfully authenticated with Yahoo IMAP using XOAUTH2!");
