【问题描述】：

我在我的 Ruby on Rails 应用程序中使用 Angular 作为前端

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('/');
        });
      }
  }]);

<li><a href="/auth/login"><span class="glyphicon glyphicon-log-in"></span> Login</a></li>
<li><a href="/auth/signup"><span class="glyphicon glyphicon-registration-mark"></span> Sign UP</a></li>
<li><a href="" ng-controller="AuthController" ng-click="logout()"><span class="glyphicon glyphicon-registration-mark" target="_self"></span> Logout</a></li>

登录和注册功能正常，但注销不工作，我的服务器显示此错误

所以我真的不明白这是什么问题

【问题讨论】：

您能否将rake routes 输出和相关routes.rb 文件内容添加到您的问题中？
我做到了。在设计配置中我使用 GET 方法
是的，这就是问题所在。您已经设置了在GET 上退出的设计，当您发送DELETE 请求时。
我已经添加了一个带有信息的答案。

标签： ruby-on-rails angularjs devise

【解决方案1】：

问题是您必须指定要使用GET 方法在您的config/initializer/devise.rb 文件中注销。

确保您的初始化程序中没有此行：

config.sign_out_via = :get

【讨论】：

当我将配置设计为 DELETE 方法时，它也不起作用。在 2016-05-06 10:49:17 +0300 ActionController::RoutingError (No route matches [DELETE] "/"): actionpack (4.2.6) lib/action_dispatch/middleware/ 开始 DELETE "/" for 127.0.0.1 debug_exceptions.rb:21:in `call'
不要将其更改为:delete，只需评论该行即可。此外，在您的评论DELETE "/" 中，您正在向您的根/ 发送删除请求，而不是users/sign_out.json。
我评论了这一行，但没有成功。于 2016-05-06 10:54:55 +0300 ActionController::RoutingError 开始为 127.0.0.1 删除“/users/sign_out.json”（没有路由匹配 [DELETE]“/users/sign_out.json”）：跨度>
更改后是否重新启动了 Rails 应用程序？
您的rake routes 行destroy_user_session 是否从GET 更改为DELETE？

【解决方案2】：

路由文件在您的情况下定义路由，除非另有说明，否则仅适用于 HTML 请求，不适用于 JSON 请求。但是您提出的请求：Started DELETE "/users/sign_out.json" for 127.0.0.1 at 2016-05-06 10:17:26 +0300 请求格式为 JSON 的数据，您的路由文件无法理解。

现在，您有两个选项可以消除此错误：

1) 确保您以HTML 格式请求，而不是通过您的代码以JSON 格式请求。

2) 您可以修改您的路线，以便它们也响应JSON 格式。以下是您将如何完成任务：

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

【讨论】：

是的，我的 javascript 日志发送此行 localhost:3000/users/sign_out.json 404（未找到），但使用 json 数据的 POST 方法有效

【解决方案3】：

在您的 routes.rb 文件中，使用 PUT 和 DELETE 等特殊方法明确定义路由。例如

devise_scope :user  do
    delete '/sign_out' => 'sessions#destroy',  :defaults => { :format => 'json' }
    put '/signup' => 'registrations#update',  :defaults => { :format => 'json' }
end

虽然这些路由已经由“devise_for :users”创建并在邮递员上工作，但没有明确创建它们，但我的 RSPec 测试失败了。
