The solution is to add one of the two pieces of code listed above. The script won’t run, and if you look in the developer console, you’ll see an error message. So on site “A” you have something like this: For example, lets say you own two domain names, and you want to use a php script from site “A” on site “B” using ajax. 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. ![]() The most common time that you might run into this as an issue is if you’re trying to make an ajax call to a php script on another domain. What is the Access-Control-Allow-Origin header Access-Control-Allow-Origin is a CORS header. One way that servers prevent cross site scripting is by using what is called “Access-Control-Allow-Origin”. The more secure way is to specifically define all places that you want to allow, which you can do like this, obviously substituting in your own origin domainĪnd thats it! What’s Access-Control-Allow-Origin? ![]() Header('Access-Control-Allow-Origin: *') ![]() The less secure way is to just allow access from any origin, you can do that by adding this as the first line in the PHP script you’re trying to run Then here’s how to fix it, you essentially have two options. Also i have added the permissions in the head and it doesn't work for me either.If you’ve ever gotten this message in the developer console: No 'Access-Control-Allow-Origin' header is present on the requested resource. I have used some SDK for PHP but is very OLD. "Access to XMLHttpRequest at ' from origin ' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource." I have used JQUERY, AJAX, AXION but but none works. ![]() Thus, the extra bits of code to restrict cross-domain calls from specific domains only. Is there a way to specify all subdomains of a site like. I have a code in php i use JQUERY for that. Access-Control-Allow-Origin cannot be set as the wildcard. I am trying to allow access to every subdomain on my site in order to allow cross subdomain AJAX calls. I want consume the Alfresco APIs with PHP. I have installing Alfresco Version 5.2.0 (201707). If you dont have access to configure Apache, you can still send the header from a PHP script. I have a issue when i consume the Alfresco APIs.
