$http doesn't send cookie in Requests
提问by Tim Daubenschütz
We are working on a RESTful Webservice with AngularJS and Java Servlets.
When the user logs in, our backend sends a "Set-Cookie" header to the frontend. In Angular we access the header via $cookies(ngCookie - module) and set it.
我们正在使用 AngularJS 和 Java Servlet 开发 RESTful Web 服务。当用户登录时，我们的后端向前端发送一个“Set-Cookie”标头。在 Angular 中，我们通过$cookies(ngCookie - 模块)访问标头并设置它。
Now that the user is logged in he can for example delete some stuff. Therefore the frontend sends a GET request to the backend. Because we work on different domains we need to set some CORS Headers and Angular does an OPTIONS request before the actual GET request:
现在用户已经登录，他可以删除一些东西。因此，前端向后端发送 GET 请求。因为我们在不同的域上工作，所以我们需要设置一些 CORS 标头，而 Angular 在实际 GET 请求之前执行 OPTIONS 请求：
OPTIONS request:
选项请求：
GET request
获取请求
We do this in Angular via $http module, but it just won't send the cookie, containing JSESSIONID.
我们通过 $http 模块在 Angular 中执行此操作，但它不会发送包含JSESSIONID.
How can I enable Angular to send cookies?

In your config, DI $httpProviderand then set withCredentials to true:
在您的配置中，DI$httpProvider然后将 withCredentials 设置为 true：
.config(function ($httpProvider) {
$httpProvider.defaults.withCredentials = true;
//rest of route code
})
Info on angularjs withCredentials: http://docs.angularjs.org/api/ng.$http
关于 angularjs withCredentials 的信息：http://docs.angularjs.org/api/ng.$http

$http.get("URL", { withCredentials: true })
.success(function(data, status, headers, config) {})
.error(function(data, status, headers, config) {});
Another thing to keep in mind: You need to have 3rd party cookies enabled. If you have it globally disabled in Chrome, click on the "i"-Symbol to the left of the domain name, then cookies, then "blocked" and unblock the target domain.
要记住的另一件事：您需要启用第 3 方 cookie。如果您在 Chrome 中全局禁用它，请单击域名左侧的“i”-符号，然后单击 cookie，然后单击“阻止”并取消阻止目标域。
