如何使用带有angular2的Symfony2 Fos用户软件包

Question

• im building authentication with symfony and angular2.

• i have already build login through fos user bundle.

• i have build crud app link https://github.com/afeef1915/Angular2-Symfony3-Demo

• i have understanding of integarting service with angular2.

• i have build login system which uses JWT from example link http://jasonwatmore.com/post/2016/09/29/angular-2-user-registration-and-login-example-tutorial

• symfony2 fos user bundles handles security param(login,logout,register).

security.xml

<routes xmlns="http://symfony.com/schema/routing"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://symfony.com/schema/routing http://symfony.com/schema/routing/routing-1.0.xsd">

<route id="fos_user_security_login" path="/login" methods="GET POST">
    <default key="_controller">FOSUserBundle:Security:login</default>
</route>

<route id="fos_user_security_check" path="/login_check" methods="POST">
    <default key="_controller">FOSUserBundle:Security:check</default>
</route>

<route id="fos_user_security_logout" path="/logout" methods="GET POST">
    <default key="_controller">FOSUserBundle:Security:logout</default>
</route>
