I make AJAX calls to URIs which belong to a different domain. Normally in IE I am able to do this via jQuery's CORS support. But this fails in Google Chrome irrespective where CORS support is set or not.Now I get an error saying something like: XMLHttpRequest cannot load . Origin is not allowed by Access-Control-Allow-Origin.Is there a setting in Google Chrome which disables the Access-Control-Allow-Origin restriction? asked Feb 1, 2012 at 19:03 1 There is a command-line switch which does the trick: --disable-web-securityJust call it like follows:$ chromium-browser --disable-web-security sure the Chrome browser is fully closed, otherwise it will only launch a new instance and the applied option will not work. answered Feb 1, 2012 at 19:06 deostrolldeostroll1,8758 gold badges25 silver badges39 bronze badges 6 You must log in to answer this question.

How To Run A Unsafe Chrome browser without CORS

Question 💬I am trying to use next-auth authentication from my chrome extension. I have spent numerous hours looking into different approaches but hitting in the wall and couldn't find a way to implement. I have implemented the next-auth as part of my NextJS app and trying to use the endpoint '/api/auth/session' to authorize from the Chrome extension. But this is always throwing CORS error. I have tried bypassing CORS by allowing all origins but no luck.I am using Prisma adapter with MongoDB and JWT strategy.secret: process.env.NEXTAUTH_SECRET, session: { strategy: 'jwt', maxAge: THIRTY_DAYS, updateAge: THIRTY_MINUTES, }, jwt: { secret: process.env.JWT_SECRET, },I have noticed that ShareGPT extension ( somehow got this working, but I couldn't figure it out. I wish there was some guide as part of next-auth docs. Please help me figure this out.How to reproduce ☕️Call the session API from chrome extension which is running in the tab of different origin. { const json = await res.json(); console.log(json)})">fetch(" {mode: "cors",credentials: "include"}).then(async (res) => { const json = await res.json(); console.log(json)})Contributing 🙌🏽Yes, I am willing to help answer this question in a PR

La respuesta de la petición, donde debe indicarse el dominio al que se le quiere dar permiso:Access-Control-Allow-Origin: esta forma, el navegador comprobará dichas cabeceras y si coinciden con el dominio de origen que realizó la petición, esta se permitirá. En el ejemplo anterior, la cabecera tiene el valor pero en algunos casos puede interesar indicar el valor *.El asterisco * indica que se permiten peticiones de origen cruzado a cualquier dominio, algo que puede ser interesante cuando se tienen API públicas a las que quieres permitir el acceso al público en general, casos como los de Google Fonts o JSDelivr, por citar un ejemplo.Estas cabeceras puedes verlas facilmente accediendo a la pestaña Network del Developer Tools del navegador. En esta sección te aparecerá una lista de peticiones realizadas por el navegador en la página actual. Si seleccionamos una petición y accedemos al apartado de cabeceras (Headers), podremos examinar si existe la cabecera Access-Control-Allow-Origin:CORS en entornos de desarrolloOtra opción sencilla y rápida para no tener que lidiar con CORS temporalmente es la de instalar la extensión Allow CORS, disponible tanto Allow CORS para Chrome como Allow CORS para Firefox. Esta extensión deshabilita la política CORS mientras está instalada y activada.Esta elección es equivalente a que todas las respuestas a las peticiones asíncronas realizadas tengan la mencionada cabecera con el valor *. Obviamente, es importante recalcar que es una opción que sólo nos funcionará en nuestro equipo y navegador, pero puede ser muy práctica para simplificar el trabajo en desarrollo.
