我一直在尝试从关于这个主题的无数其他问题中尝试各种解决方案,但没有任何运气......
我正在尝试在 AngularJs 中设置一个带有前端的 rails-api 项目。他们将在不同的领域。我可以毫无问题地发出 GET 请求。但是当我尝试执行 PUT 时,我会进入 Chrome 控制台:
XMLHttpRequest cannot load http://0.0.0.0:3000/thingies/1.
No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'http://localhost:9000' is therefore not allowed access
这是我失败的请求的样子:
Remote Address:0.0.0.0:3000
Request URL:http://0.0.0.0:3000/thingies/1
Request Method:OPTIONS
Status Code:404 Not Found

这是我在 AngularJs 中的 app.js:
angular
.module('myApp', [
'ngCookies',
'ngResource',
'ngRoute',
'ngSanitize',
'restangular',
])
.config(function ($routeProvider,RestangularProvider, $httpProvider) {
$httpProvider.defaults.useXDomain = true;
delete $httpProvider.defaults.headers.common["X-Requested-With"];
$httpProvider.defaults.headers.common["Accept"] = "application/json";
$httpProvider.defaults.headers.common["Content-Type"] = "application/json";
$routeProvider
.when('/', {
templateUrl: 'views/home.html',
controller: 'HomeCtrl'
.otherwise({
redirectTo: '/'
});
RestangularProvider.setBaseUrl('http://0.0.0.0:3000');
});
这是在我的 Rails 项目中:
应用程序.rb:
class Application < Rails::Application
config.action_dispatch.default_headers.merge!({
'Access-Control-Allow-Origin' => '*',
'Access-Control-Request-Method' => '*'
})
end
我的 routes.rb、application_controller.rb 和 thingy_controller 是默认的脚手架文件。(我尝试根据 CORS 的其他解决方案修改它们,但没有任何运气。)
我也使用过 POSTMAN(Chrome 扩展程序),看看是否可以使用 PUT。请求顺利通过。
如果有人能指出我正确的方向,我将不胜感激!
