![]() Please note, these are only needed for ionic serve and ionic run -l.įirst we will need to set up the proxies in our ionic.project file. It is important to note that the browser adds in the Origin header. Since the server is sending a fresh request to your destination, there will be no origin and therefore, no CORS needed. The Ionic CLI introduced the ability to have a proxy server issue requests for you to get around any CORS issues you may have. Will take our requests, issue a new request to the API endpoint, receive the response, and forward it back to our app so we can get around CORS issues. What we’d need to do to get around these CORS issues is have a proxy server that In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers. Let’s look how the Ionic CLI providesĪn easily configurable proxy server. ![]() What we need, then, is a request that does not specify an origin. However, we can’t always control the endpoint we are accessing. There are two ways to solve the issue: The first, and easier, solution is to just allow all origins from your API endpoint. Dealing with CORS in IonicĬORS is only an issue when we are running or testing our app when running ionic serve or ionic run -l. The app runs, thus firing a browser on the phone/simulator to run the files from the server (or whatever your local IP address is).Īny AJAX request sent out to a host other than 192.168.1.1:8100 will require a CORS preflight request to see if it can access the resource.The app runs, thus firing a browser on the phone/simulator to run the files that were copied over, something like: file://some/path/Your origin will not exist, since you are running off of a file:// URI therefore, any request outwards will not require a CORS request. ![]()
