How to login with @RestController and send the object to angularjs

I have some trouble figuring out how to create a login form in angularjs using springboot.

I can register a user and send the data to the database but the problems begin when i want to login.

in angularjs i have a function like this

  function Login(username, password, callback) {


        $http.post('/api/authenticate', { username: username, password: password })
           .success(function (response) {
              callback(response);
           });

    }

What i managed to do but probably is't right:

@RequestMapping(value = "/authenticate/{id}",method = RequestMethod.GET)
public  User getUser(@PathVariable Integer id) {

    return repo.findOne(id);
}

This gives me following json 

{"id":2,"username":"jdoe","password":"$2a$10$5hgIyQr.K9wb8cXEyWGbROAU.rkYzd19vP7ajHpwp1KUYdShfcPn.","lastname":"doe","firstname":"john","customfield":"Hello there"}

But now i have following problems and questions :

How can i check if the username and password is equal to the username and password of json by going to api/authenticate ? (without {id})

can i hide this json from the users ?

Is this safe ?

how will angular now all the users propertys ? (i suggest i can retrieve this from the json)

any pro tips on how to solve this?

Solution

  • From AngularJS you are calling HTTP POST method and at Spring side you have declared as HTTP GET, which is wrong.

    Correct request mapping is 

     @RequestMapping(value = "/api/authenticate",method = RequestMethod.POST, consumes = "application/json")
 @ResponseBody
 public User getUser(@RequestBody User user) {
 //here request body contains User POJO object's payload (JSON object)

   //You are getting username from JSON, 
   //so you need to update your call to findOne method
   return repo.findOne(user.getUserName());
}
