Question

我在AngularJS中有一个前端，在RoR中有后端与Devise + Doorkeeper + RocketPants。现在我已正确使用CORS，我可以成功地从我的API获取json响应（如果我关闭门卫保护）。但现在我正在尝试实现用户密码凭证流程：

关于门卫：

  resource_owner_from_credentials do |routes|
    request.params[:user] = {:email => request.params[:username], :password => request.params[:password]}
    request.env["devise.allow_params_authentication"] = true
    request.env["warden"].authenticate!(:scope => :user)
  end

在angularjs（src：nils-blum）上：

var payload = "username="+username+"&password="+password+"&" +
        "client_id="+client_id+"&client_secret="+client_secret+
        "&grant_type=password"

$http({method: 'POST',
    url: scope.booksh_server + '/oauth/token',
    data:   payload,
    headers: {'Content-Type':'application/x-www-form-urlencoded'}
    }
).success(function (data) {
            tokenHandler.set(data.access_token);
            scope.$broadcast('event:authenticated');
});

注意：Nils的方法使用有效负载作为对象与params，而不是字符串。在我的情况下，它给我带有效负载的POST，而不是FORM params，因此不起作用。

当我输入错误的用户/密码时，rails log会说：

    Started POST "/oauth/token" for 127.0.0.1 at 2013-11-22 15:21:08 +0400
  Doorkeeper::Application Load (0.5ms)  SELECT "oauth_applications".* FROM "oauth_applications" WHERE "oauth_applications"."uid" = '981d6d654f5e709b2ca3437401c993a6d09cc91cc3fb16b8e2b3191e6421029c' AND "oauth_applications"."secret" = 'f92c4ec969525352bd03ec1eb810a9952cd0814d37ce5b2b02e8a928b2561e10' ORDER BY "oauth_applications"."id" ASC LIMIT 1
  User Load (0.9ms)  SELECT "users".* FROM "users" WHERE "users"."email" = 'undefined' ORDER BY "users"."id" ASC LIMIT 1

Chrome开发者工具会将此请求显示为已取消。 Firebug显示302 Found状态的空响应。当我从chrome REST App执行相同的POST时，UPD：服务器执行相同的操作，我得到302 Found，然后将其重定向到设计页面的sign_in。

此外，如果我输入正确的用户/密码，firefox会显示空响应200 OK，REST会收到带有访问令牌的正确json，并且chrome显示取消响应并抛出CORS错误：

XMLHttpRequest cannot load http://0.0.0.0:3000/oauth/token. Origin http://0.0.0.0:9000 is not allowed by Access-Control-Allow-Origin.

服务器日志：

   (28.1ms)  COMMIT

我该如何使这项工作？我需要POST / oauth / token来处理身份验证，并在电子邮件/密码正确的情况下使用access_token进行响应。感谢任何帮助，我已经厌倦了被困在这里）

耶！最后我做到了。仍然不知道为什么在整个网络的教程中它更容易。

所以，问题来自：我的ApplicationController（根目录，而不是处理API的那个）我跟踪CORS：

  before_filter :set_headers

  def set_headers
    headers['Access-Control-Allow-Origin'] = 'http://0.0.0.0:9000'
    headers['Access-Control-Allow-Methods'] = 'GET, POST, PATCH, PUT, DELETE, OPTIONS, HEAD'
    headers['Access-Control-Allow-Headers'] = '*,X-Requested-With,Content-Type,If-Modified-Since,If-None-Match'
    headers['Access-Control-Max-Age'] = '86400'
  end

深入研究这个问题我发现当我调用/ oauth / token时没有调用此函数，但是当我转到使用ApplicationController处理的API之外的任何其他路径时调用此函数

门卫有自己独立于app控制器的控制器。文档描述了他们的行为改变（link），所以这有助于我：

routes.rb：

use_doorkeeper do
    controllers tokens: 'custom_tokens'
end

custom_tokens_controller.rb：

class CustomTokensController < Doorkeeper::TokensController

  include AbstractController::Callbacks
  before_filter :set_headers

  def set_headers
    puts 'headers set'
    headers['Access-Control-Allow-Origin'] = 'http://0.0.0.0:9000'
    headers['Access-Control-Allow-Methods'] = 'GET, POST, PATCH, PUT, DELETE, OPTIONS, HEAD'
    headers['Access-Control-Allow-Headers'] = '*,X-Requested-With,Content-Type,If-Modified-Since,If-None-Match'
    headers['Access-Control-Max-Age'] = '86400'
  end
end

重要的是将Callbacks包含在控制器中，因为门卫控制器是从Metal继承的，因此如果没有包含，则无法找到before_filter。

它现在看起来很好：它验证我的用户/密码对，并返回access_token（我希望，它的工作原理：D）。如果出现问题，现在应该重定向。这是我知道解决的问题（自定义监管器故障），所以现在一切正常。咦！这很长...如果有人知道为什么基于互联网的食谱没有帮助，请发表您的想法=）
