I am pulling in an Iframe that has javascript included in it. I have installed the fruitcake cors package and set the config file to be wide open. I also added the "Access-Control-Allow-Origin' header to the xmlhttp request just in case because I am confused on who is actually denying the request. Here is the error I am getting -
Access to XMLHttpRequest at "https://site-that-i-am-posting-to" from origin "https://where-the-iframe-is-sourced-from" has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present of the requested resource.
Figured it out. I needed to add the correct request headers to the xmlhttprequest like this -
xhrapi.setRequestHeader('Origin', 'https://site-posting-from.com');
xhrapi.setRequestHeader('Access-Control-Request-Method', 'POST');
And then it worked. Thanks to anyone that tried to help!

I am developing a Laravel API + Vue.js frontend app. Those 2 projects are on separate servers. I am having a CORS policy problem in production (on local I had, but I managed to fix it).
So basically, there are 2 errors right now. I am having this error:
Access to XMLHttpRequest at '--Laravel url--' from origin '--Vue url--' has been blocked by CORS policy: Request header field content-type is not allowed by Access-Control-Allow-Headers in preflight response.
While my co-worker is getting this error:
Access to XMLHttpRequest at '--Laravel url--' from origin '--Vue url--' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
We tried a few things:
Configurating CORS on Laravel side:
setting CORS middleware - no effect
changing CORS config .php file - no effect
Configurating CORS on Vue side:
adding origin header to form - no effect
The response is also displaying in browser as being same-site although it is not.
Anyone can help? We have been searching for answer for nearly 3 days.
As Jazerix answered in a comment, going Sanctum is probably the right way because it has most stuff prepared.
On local development I am facing following error on ajax request:
Access to XMLHttpRequest at 'http://pmb.local/jsonapi/product' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Need to the following change this this file
Ddont forget to run:
php artisan optimize
am using ziggy with laravel and inertia, now using google login, i get the following error:
has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
here is my laravel routes:
Route::get('auth/{provider}', 'Auth\LoginController#redirectToProvider')
->name('login.provider');
Route::get('auth/{provider}/callback', 'Auth\LoginController#handleProviderCallback')
->name('login.callback');
how would i solve it please?
The response from the google service is missing the header Access-Control-Allow-Origin: * so the browser is blocking it.
Try to research a way to have that header included in the response.
I am trying to make a cross domain request from my React app (localhost:3000) to my Laravel PHP app (localhost:8000). I believe I have the back end set up to accept cross domain requests. I used this: https://github.com/barryvdh/laravel-cors
I seem to have all the parameters from this answer (https://stackoverflow.com/a/38087435/1555312), so I don't get why mine doesn't work. I actually see a 200 response + the expected body when I use the chrome console.
Here is the error I see in my console:
Failed to load http://localhost:8000/api/v1/upload-sessions: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access.
Here is how my POST request looks like:
OPTIONS request:
POST request:
Expected response is sent, even though it complains about the CORS issue:
You need to set Access-Control-Allow-... on the response, not the request.
Once you remove that from the request, you probably won't need a pre-flight, so the OPTIONS request won't happen.
I'm trying to implement a login service on a Web app using Sencha Touch.
I already have a REST service working properly (I can test it using chomr extension Dev HTTP Client).
Now, the request is an Ajax request after doing some research, I've found out that cross-domain requests are protected, according to CORS.
I modified my Ajax client, adding:
useDefaultXhrHeader: false
when constructing the Ajax request, and I added to the headers:
Access-Control-Allow-Headers: x-requested-with
Access-Control-Allow-Origin: *
in my response.
Still using the Dev HTTP Client, I can now see my headers correctly set in the response.
But, in my app, I keep getting the error:
No 'Access-Control-Allow-Origin' header is present on the requested resource
If I use the --disable-web-security parameter when launching Chrome, everything works as it should, headers are sent (or at least, they are not blocked anymore by Chrome), but obviously, this is not the proper way to do it.
Can someone help me out on this?
Please follow the link http://enable-cors.org/server_apache.html and enable cors on your server. You client ajax request is correct but you still need enable cors on the server.
