Question

ich für Front-End in meinem Ruby-Winkel verwenden on Rails app

angular.module('rails_api') 
    .controller('AuthController', ['$scope', '$location', '$http', 'Auth', function($scope, $location, $http, Auth){ 
    //auth 
    var config = { 
     headers: { 
     'X-HTTP-Memthod-Override': 'POST' 
     } 
    } 

    $scope.login = function() { 
     Auth.login($scope.user, config).then(function(user) { 
      console.log(user); 
     }, function(error) { 
     }); 

     $scope.$on('devise:login', function(event, currentUser){ 
     $location.path('/'); 
     }); 

     $scope.$on('devise:new-session', function(event, currentUser) { 
      // user logged in by Auth.login({...}) 
     }); 
    } 

    $scope.signup = function() { 
     Auth.register($scope.user, config).then(function(registeredUser) { 
      console.log(registeredUser); // => {id: 1, ect: '...'} 
     }, function(error) { 
      // Registration failed... 
     }); 

     $scope.$on('devise:new-registration', function(event, user) { 
      $location.path('/'); 
     }); 
     } 

     $scope.logout = function() { 
     var config = { 
      headers: { 
       'X-HTTP-Method-Override': 'DELETE' 
      } 
     }; 
     // Log in user... 
     // ... 
     Auth.logout(config).then(function(oldUser) { 
      //console.log("oldUser"); 
      //alert(oldUser.name + "you're signed out now."); 
     }, function(error) { 
      console.log(error); 
     }); 

     $scope.$on('devise:logout', function(event, oldCurrentUser) { 
      $location.path('/'); 
     }); 
     } 
    }]); 

..

Die Anmeldung und Registrierung Funktion Arbeit alles in Ordnung, aber logout nicht funktioniert, und meine Server Diesen Fehler

Also wirklich verstehe ich nicht, was das Problem

Answer 1

ist

Die Routen-Datei mit den Routen in Ihrem Fall definiert, nur arbeiten HTML Anfragen, nicht für JSON Anfrage, sofern nicht anders angegeben. Aber die Anfrage, die Sie machen: Started DELETE "https://stackoverflow.com/users/sign_out.json" for 127.0.0.1 at 2016-05-06 10:17:26 +0300 fordert Daten im Format JSON, die Ihre Routen-Datei nicht versteht.

Nun haben Sie zwei Möglichkeiten, diesen Fehler loszuwerden:

1) Stellen Sie sicher, dass Sie in HTML-Format und nicht in JSON Format durch den Code.

2) Sie können Ihre Routen so ändern, dass sie auch auf das Format JSON reagieren. Im Folgenden sehen, wie Sie die Aufgabe erfüllen würde:

resources :users, :only => [:show], :defaults => { :format => 'json' } 

Answer 2

Das Problem ist, dass Sie angegeben haben müssen, dass Sie GET Methode, um sich abzumelden in Ihrer config/initializer/devise.rb Datei verwenden möchten.

Stellen Sie sicher, diese Zeile nicht haben in Ihrem initializer:

config.sign_out_via = :get
