2. Now you can run any wordpress default api from mobile app or any other source or by postman. for example hit this url from your app or by postman. https://example.com/wp-json/wp/v2/posts
3. By app or by postman, When you will login with valid details (using rest api) you will get back a token. To login and get token, run the following url by postman or by app
https://example.com/wp-json/jwt-auth/v1/token
4. By this way you will get a token as shown in picture
Now use this token to get logged in user details, for example
5. make function in function.php
function checkloggedinuser()
{
$currentuserid_fromjwt = get_current_user_id();
print_r($currentuserid_fromjwt);
exit;
}
add_action('rest_api_init', function ()
{
register_rest_route( 'testone', 'loggedinuser',array(
'methods' => 'POST',
'callback' => 'checkloggedinuser'
));
});
6. Now again run this new url in postman or in app to get logged in user details.
https://example.com/wp-json/testone/loggedinuser
(replace example.com with your url)
