You can use an middleware that adds Access-Control-Allow-Origin to an http response header. You should note that a domain has to be specified if an http request includes cookie information. CORS, or Cross Origin Resource Sharing, is a mechanism for browsers to let a site running at origin A to request resources from origin B. If you want to limit the source, you should specify the domain in the configuration such as Access-Control-Allow-Origin. What is the Access-Control-Allow-Origin header Access-Control-Allow-Origin is a CORS header. The simplest method to enable CORS is to add Access-Control-Allow-Origin:* to the response header from WEB servers, which allows CORS from any source. Without CORS configuration, web applications can not access a different origin. In order to prevent cross site scripting (XSS) and cross site request forgeries, JavaScript's asynchronous communication such as Ajax follows the same origin policy, which bans access to a different origin. Request header field content-type is not allowed by Access-Control-Allow-Headers. ) to access an web application on a different origin (e.g. The answer is in the error response content-type. The server responds with Access-Control-Allow-Origin: restricting access to the requesting origin domain only.It also responds with Access-Control-Allow-Methods, which says that POST and GET are valid methods to query the resource in question (this header is similar to the Allow response header, but used strictly within the context of access control). Thus, the extra bits of code to restrict cross-domain calls from specific domains only. Therefore, CORS means allowing an web application on a certain origin (e.g. Access-Control-Allow-Origin cannot be set as the wildcard. Origin consists of protocol, domain and port number such as. nd("") Īccess to XMLHttpRequest at '' from origin ' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.CORS stands for Cross Origin Resource Sharing. $tWidgetProp( "authService", "text", text) htaccess file on the root folder of y.com not x.com :) For example you create an AngularJS app on x.com domain and create a Rest API on y.com, you should set Access-Control-Allow-Origin '' in the. For simple CORS requests, the server only needs to add the following header to its response: Access-Control-Allow-Origin: .tRequestHeader("Access-Control-Allow-Origin", url_home) htaccess config must be done on the server hosting the API. tRequestHeader("Accept", "application/json") In this tutorial we will explain how to permit CORS requests for multiple origins in PHP. tRequestHeader("Access-Control-Request-Method", "POST") Var url_home= ' //tRequestHeader("Content-Type", "application/json") So, the code that I used is similar to this one: Limiting the possible Access-Control-Allow-Origin values to a set of allowed origins requires code on the server side to check the value of the Origin request header, compare that to a list of allowed origins, and then if the Origin value is in the list, set the Access-Control-Allow-Origin value to the same value as the Origin value. If I enable " Moesif CORS extension" for google chrome I'm able to send a POST to the server and this one answer with a positive message. I'm trying to make a connection with the internal Intranet system.
