Question

我正在使用Devise注册，登录，从AngularJS客户端注销用户，注册和登录工作正常，但退出似乎对我失败，我不知道问题出在哪里。

运行以下代码客户端时：

$http({
    method : 'DELETE',
    url : 'http://localhost:3000/users/sign_out'
}).success(function(response) {
   console.log(response);
}).error(function(response) {
   console.log(response);
});

我的浏览器控制台说明如下：

OPTIONS http://localhost:3000/users/sign_out 404 (Not Found) angular.min.js:72
OPTIONS http://localhost:3000/users/sign_out No 'Access-Control-Allow-Origin' header is      present on the requested resource. Origin 'http://karm.local.mobi' is therefore not allowed access. angular.min.js:72
XMLHttpRequest cannot load http://localhost:3000/users/sign_out. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://karm.local.mobi' is therefore not allowed access. (index):1

终端中的webbrick说：

然而，当我使用像Dev HTTP Client之类的东西时，webbrick终端似乎工作得很好：

Started DELETE "/users/sign_out" for 127.0.0.1 at 2013-11-20 13:51:45 +0100
Processing by SessionsController#destroy as */*
Completed 200 OK in 0ms (Views: 0.1ms | ActiveRecord: 0.0ms)

这对我来说意味着跨域是问题所在。但是我登录或注册用户的调用与DELETE相同。允许CORS的ruby双边过滤器对于所有Devise方法也是相同的。

我错过了一些明显的东西吗？或者还有另一种方法可以解决这个问题吗？提前谢谢。

在我的控制器中允许CORS的方法：

def cors_set_access_control_headers
  headers['Access-Control-Allow-Origin'] = '*'
  headers['Access-Control-Allow-Methods'] = 'POST, GET, OPTIONS, DELETE, PUT'
  headers['Access-Control-Max-Age'] = "1728000"
end

def cors_preflight_check
  if request.method == :options
    headers['Access-Control-Allow-Origin'] = '*'
    headers['Access-Control-Allow-Methods'] = 'POST, GET, OPTIONS, DELETE, PUT'
    headers['Access-Control-Allow-Headers'] = 'X-Requested-With, X-Prototype-Version'
    headers['Access-Control-Max-Age'] = '1728000'
    render :text => '', :content_type => 'text/plain'
  end
end

最终我能够使用Rack Cors来解决问题。仍然不确定什么是错的，但我很高兴它的排序。
