简单：一方面 Angularjs 在服务器上运行

'use strict'

### Sevices ###

angular.module('app.services', [])

.factory 'Contents', ($resource) ->
      Contents = $resource('http://127.0.0.1\\:3000/documents.json')

在另一侧，在另一台服务器上运行的 rails 后端

Started OPTIONS "/documents.json" for 127.0.0.1 at 2013-04-12 15:22:27 +0900

ActionController::RoutingError (No route matches [OPTIONS] "/documents.json"):

我不明白，因为我已经有一个backendjs 可以正常运行..backendjs，虽然没有发送OPTIONS 请求...

在我的 Rails 项目中，我现在直接在代码中设置我的 Header，因为我使用 Webrick 进行开发：

class ApplicationController < ActionController::Base
  protect_from_forgery
  after_filter :set_access_control_headers

  def set_access_control_headers
    headers['Access-Control-Allow-Origin'] = '*'
    headers['Access-Control-Request-Method'] = '*'
    headers['Access-Control-Allow-Headers'] = '*'
  end
end

自己找到了解决方案：

    App.config([
  '$routeProvider'
  '$httpProvider'
  '$locationProvider'

($routeProvider, $httpProvider, $locationProvider, config) ->

  $routeProvider

    .when('/contents', {templateUrl: '/partials/contents.html'})
    .when('/view1', {templateUrl: '/partials/partial1.html'})
    .when('/view2', {templateUrl: '/partials/partial2.html'})

    # Catch all
    .otherwise({redirectTo: '/contents'})

  delete $httpProvider.defaults.headers.common["X-Requested-With"]

  # Without server side support html5 must be disabled.
  $locationProvider.html5Mode(false)
])

这帮助我在这里找到：AngularJS 对跨域资源执行 OPTIONS HTTP 请求

  app.config(['$httpProvider', function ($httpProvider) {
  //Reset headers to avoid OPTIONS request (aka preflight)
  $httpProvider.defaults.headers.common = {};
  $httpProvider.defaults.headers.post = {};
  $httpProvider.defaults.headers.put = {};
  $httpProvider.defaults.headers.patch = {};
}]);
