If you can use no-cors, set it in the headers, like: var opts = { headers: { 'mode':'cors' } } fetch(url, opts) If you do not control the API, there is little you can do.

By default, fetch () makes a GET request, but you can use the method option to use a different request method: const response = await fetch ("https://example.org/post", { method: "POST", // ... }); If the mode option is set to no-cors, then method must be one of GET, POST or HEAD.

"no-cors" – only safe cross-origin requests are allowed. This option may be useful when the URL for fetch comes from a 3rd-party, and we want a “power off switch” to limit cross-origin capabilities.

L'API Fetch (en anglais, le verbe fetch signifie récupérer) fournit une interface JavaScript pour accéder et manipuler certaines parties du protocole, comme les requêtes et les réponses. Elle fournit également une méthode globale fetch () qui permet un accès pratique aux ressources récupérées de façon asynchrone sur le réseau.

An example demonstrates fetching data from the GitHub API using 'no-cors' mode, showing how to check the status and 'Content-Type' header despite limitations in accessing the response body. Step-by-Step Guide

When using JavaScript’s fetch API, you may come across a situation where you need to make a cross-origin request and specify the mode as no-cors. This can be useful when you want to fetch data from a different domain but don’t need access to the response data.

fetch() lets you make network requests similar to XMLHttpRequest (XHR). The main difference is that the Fetch API uses Promises, which has a simpler API to help you avoid the complicated callbacks in the XMLHttpRequest API.

https://javascript.info › fetch-crossorigin

Fetch fails, as expected. The core concept here is origin – a domain/port/protocol triplet. Cross-origin requests – those sent to another domain (even a subdomain) or protocol or port – require special headers from the remote side. That policy is called “CORS”: Cross-Origin Resource Sharing.

https://developer.mozilla.org › en-US › docs › Web › API › Request › mode

The mode read-only property of the Request interface contains the mode of the request (e.g., cors, no-cors, same-origin, navigate or websocket.) This is used to determine if cross-origin requests lead to valid responses, and which properties of the response are readable.
