How can I get the OAuth 2.0 authorization code?

[umbrella-artem-romanov]

I can't get the authorization code after I call $linkedIn.authorize(). Please, help me.

This is how I do it. Hope this does help you.

var auth = function() {
    var loginURL = loginURL + '?response_type=code&client_id=' + clientId + '&scope=' + scope + '&state=' + stateId + '&redirect_uri=' + redirectURI;
    var loginWindow = $window.open(loginURL, '_blank', 'location=0,toolbar=0');
    loginWindow.addEventListener('load', function(event) {
        var URL = event.target.baseURI;
        var isRedirect = URL.substring(0, redirectURI.length) === redirectURI;
        if(isRedirect) {
            var code = (URL).split("code=")[1];
            code = code.split("&")[0]; // <- this here is your code.
            var error = (URL).split("error=")[1];
            loginWindow.close();
            if(!error) {
                // All is good. Do something here.
            } else {
                // Somethings wrong. Check and do something about it.
            }
        }
    });
};
$linkedIn.isAuthorized().then(function(isAuthorized) {
    if(isAuthorized) {
        auth();
    } else {
        $linkedIn.authorize().then(function() {
            $linkedIn.profile('me', "id,firstName,lastName,emailAddress").then(function(linkedinUser) {
                auth();
            });
        });
    }
});
