我的应用程序中有 2 个部分 - Angular 前端和轨道服务器。而且由于它是不同的域,因此默认情况下请求不起作用。有很多工作人员,包括堆栈,但它对我不起作用。
这是我在角度控制器中的方法:
$scope.test =->
# transform = (data) ->
# $.param data
$http.post('http://localhost:3000/session/create', 'token=some',
headers:
'Access-Control-Allow-Origin': 'http://localhost:9000',
'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, OPTIONS',
'Access-Control-Allow-Headers': 'Content-Type, X-Requested-With'
# transformRequest: transform
).success (responseData) ->
console.log(responseData)
我评论了转换数据,服务器响应没有差异。
我配置了这样的应用程序(在某个帖子中看到了这一点(:
.config ["$httpProvider", ($httpProvider) ->
$httpProvider.defaults.useXDomain = true
delete $httpProvider.defaults.headers.common["X-Requested-With"]
]
我想这使得请求不像 ajax(但我不确定(。
但是我的请求中没有标题。他们都在某个领域Access-Control-Request-Headers:access-control-allow-origin, accept, access-control-allow-headers, access-control-allow-methods, content-type
:
Request URL:http://localhost:3000/session/create

Chrome 控制台:
OPTIONS http://localhost:3000/session/create 404 (Not Found) angular.js:6730
OPTIONS http://localhost:3000/session/create No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9000' is therefore not allowed access. angular.js:6730
XMLHttpRequest cannot load http://localhost:3000/session/create. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9000' is therefore not allowed access. localhost/:1
其他无关紧要的信息:在服务器上:
class ApplicationController < ActionController::Base
before_filter :allow_cross_domain_access
protected
def allow_cross_domain_access
headers['Access-Control-Allow-Origin'] = '*'# http://localhost:9000
headers['Access-Control-Allow-Headers'] = 'GET, POST, PUT, DELETE'
headers['Access-Control-Allow-Methods'] = %w{Origin Accept Content-Type X-Requested-With X-CSRF-Token}.join(',')
headers['Access-Control-Max-Age'] = '1728000'
end
end
路线post "session/create"
很明显。和会话控制器:
class SessionController < ApplicationController
respond_to :json, :html, :js
def create
respond_with "logged in"
# render nothing: true
end
end
我使用最新版本的angular 1.2.0.rc-2。 这是我在GitHub上的项目
您在示例中混合了请求和响应标头。
当执行跨域请求 (CORS( 时,您希望发出与普通 GET 不同的任何内容 - 例如 POST 或添加自定义标头 - 浏览器将首先发出 OPTIONS 请求。以下是您在开发者控制台中看到的内容:
OPTIONS http://localhost:3000/session/create 404 (Not Found) angular.js:6730
然后,服务器应将适当的标头添加到 OPTIONS 请求的响应中。
因此,您可以从 Angular 调用中删除自定义标头。接下来,您需要确保您的服务器/应用程序应答 OPTIONS 请求,而不是返回 404。
