CORS error with jquery
ajax, cors, javascript, jquery
Solution
An important note for those newer coders is that everything on http://enable-cors.org/server.html assumes you have a server running. If you're new, like I was originally, these type of answers don't help.
If you've just made some code on your computer, CodePen, etc - you can't configure this.
There's an important difference between server-side and client-side scripting - your jquery is running on the client side (that is, the users computer / browser) and as such there's no such thing as setting the headers there.
I finally started making progress with this issue when I set up my own server and my own PHP files (PHP is server-side, as such its processed on the server - not the browser) and was able to start making requests just fine.
Adding this for anyone who is being drowned in answers involving the `"Header set Access-Control-Allow-Origin "*"` answer. It really frustrated me when I started as well.
Problem
I'm currently working on a project using the cloudapp API and I'm using jquery. Here is my code: ``` $.ajax({ headers: { "Accept": "application/json"}, type: 'GET', url: 'http://cl.ly/2wr4', crossDomain: true, success: function(data, textStatus, request){ console.log(data); } }); ``` When I run this I get 200 OK response and this error in Firefox: ``` Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://cl.ly/2wr4. This can be fixed by moving the resource to the same domain or enabling CORS. ``` and this error in Google Chrome: ``` XMLHttpRequest cannot load http://cl.ly/2wr4. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. ``` and nothing is logged to the console. Please how can I fix this error? Thanks.
