# 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"
# }

json = Chilkat::CkJsonObject.new()
success = json.LoadFile("qa_data/tokens/yahooMail.json")
if (success != true)
    print "Failed to load Yahoo Mail access token file." + "\n";
    exit
end

# Do OAuth2 authentication by using the access token as the password in the Login method below...
imap = Chilkat::CkImap.new()

imap.put_Ssl(true)

# Connect to the Yahoo IMAP server.
success = imap.Connect("imap.mail.yahoo.com")
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end

# Indicate that XOAUTH2 authentication is to be used:
imap.put_AuthMethod("XOAUTH2")

# Login
# Use the email address of the Yahoo Mail account that granted authorization.
success = imap.Login("user@yahoo.com",accessToken)
if (success != true)
    print imap.lastErrorText() + "\n";
else
    print "Successfully authenticated with Yahoo IMAP using XOAUTH2!" + "\n";
end

# Get the list of mailboxes.

end

# Sample output looks like this:

# Archive
# Bulk Mail
# Draft
# Inbox
# Inbox/emailsWithAttach
# Inbox/test
# Sent
# Trash

# Disconnect from the IMAP server.
