我刚开始使用angularjs,我使用rails作为后端api。我已经成功设置了角度轨道资源(https://github.com/FineLinePrototyping/angularjs-rails-resource)和机架,以便从轨道获取数据。当我尝试保存节日时,我收到以下错误:
XMLHttpRequest cannot load http://localhost:3000/festivals. Origin http://localhost:9000 is not allowed by Access-Control-Allow-Origin.
这是我的代码,
应用程序/脚本/指令/ festival_form.coffee
'use strict'
angular.module('MFNApp')
.directive 'festivalForm', ->
return {
compile: (scope, element, attributes) ->
console.log 'compile'
link: (scope, element, attributes) ->
console.log 'link'
controller: ($scope, Festival) ->
$scope.newFestival = new Festival
console.log $scope.newFestival
$scope.save = ->
$scope.newFestival.save().then(
(festival) ->
console.log 'success'
# $scope.festivalForm.$setPristine()
# $scope.newFestival.$dirty = false
,
(response) ->
console.log 'failure'
# $scope.festivalForm.$setValidity(false)
# angular.forEach response.data, (value, key) ->
# $scope.festivalForm.$error[key] = value[0]
)
}
这是使用角轨资源的节日工厂
应用程序/脚本/服务/ Festival.coffee
'use strict'
angular.module('MFNApp')
.factory 'Festival', (railsResourceFactory) ->
railsResourceFactory
url: 'http://localhost:3000/festivals',
name: 'festival'
这是视图
应用程序/视图/ fesitvals / new.html
<div festival-form>
<form>
<fieldset>
<legend>Festival Information</legend>
<div class="row">
<div class="large-12 columns">
<label>Festival Name</label>
<input ng-model='newFestival.name' type="text" placeholder="Name of your festival...">
</div>
</div>
<div class="row">
<div class="large-12 columns">
<label>Description</label>
<input ng-model='newFestival.description' type="text" placeholder="About your festival...">
</div>
</div>
<button ng-click='save()'>Save</button>
</fieldset>
</form>
</div>

您必须允许网络API支持来自该域(http://localhost:9000
)的请求,或者您可以按照此处所述为所有域打开Allow anything through CORS Policy

错误有点误导,因为它似乎是一个跨源请求错误。这实际上只是rails控制器中的一个错误。因此,如果您将rails作为后端连接到angular并遇到此错误,则可能只是错误的rails代码。希望这有帮助!
