Origin ' is therefore not allowed access. No 'Access-Control-Allow-Origin' header is present on the requested resource. ) don't match, the browser's Same Origin Policy takes effect and CORS is required for the request to be made.ĬORS errors are common in web apps when a cross-origin request is made but the server doesn't return the required headers in the response (is not CORS-enabled): with ionic serve) and the origin of the resource being requested (e.g. When the origin where your app is served (e.g. For example, apps running in Capacitor have capacitor://localhost (iOS) or (Android) as their origin. In order to know if an external origin supports CORS, the server has to send some special headers for the browser to allow the requests.Īn origin is the combination of the protocol, domain, and port from which your Ionic app or the external resource is served. htaccess.Cross-Origin Resource Sharing (CORS) is a mechanism that browsers and webviews - like the ones powering Capacitor and Cordova - use to restrict HTTP and HTTPS requests made from scripts to resources in a different origin for security reasons, mainly to protect your user's data and prevent attacks that would compromise your app. conf ( nf et nf sont des noms couramment attribués à ces fichiers) ou dans un fichier. La configuration se trouve généralement dans un fichier.

Par exemple, dans Apache, ajoutez une ligne comme celle qui suit à la configuration du serveur (dans la section appropriée, ,, ou ). L'instruction exacte pour définir les en-têtes dépend de votre serveur web. Pour autoriser n'importe quel site à faire des requêtes CORS sans utiliser le caractère générique * (par exemple, pour fournir des authentifiants), votre serveur doit lire la valeur de l'en-tête Origin de la requête et l'utiliser dans Access-Control-Allow-Origin, tout en ajoutant un en-tête Vary: Origin pour indiquer que certains en-têtes sont définis dynamiquement selon leur origine.
