问题 I'm gettin the normal cors error on my firebase storage when I do a get call on an html file: Request header field Access-Control-Allow-Origin is not allowed by Access-Control-Allow-Headers in preflight response.

How to setup the CORS configuration in keycloak to allow an ajax request?

由 房东的猫 提交于 2019-12-29 08:15:34
问题 I am trying to use keycloak as an authentication server. I try to get the token with an ajax request. It works fine in curl but not in my angular due to CORS. I have set the client to Direct access grant enable to true and I have added * to Web Origin. fetch("http://localhost:8080/auth/realms/master/protocol/openid-connect/token", { body: "grant_type=password&client_id=admin-cli&username=adrien&password=adrien&undefined=", headers: { Accept: "application/json, text/plain, */*,application/x

Why is CORS without credentials forbidden?

由 混江龙づ霸主 提交于 2019-12-29 08:03:14
问题 I'm trying to understand why cross domain requests without credentials is not allowed (by default, without setting up server to return Access-Control-Allow-Origin header). In case of request with credentials all is pretty straightforward - one can fulfill some malicious actions on your behalf on other sites, for example on facebook, if you have logged in on it. For example this request: xhr = new XMLHttpRequest(); xhr.open('GET', 'http://www.google.com'); xhr.send(); produce an error ( I

CORS requests with session/cookie

由 主宰稳场 提交于 2019-12-29 07:51:51
问题 My application has a PHP server and a client (a JS single-page app). They are separate projects and deployed in different domains. The client consumes a RESTful API exposed by the server. This application is to be integrated with a third party which handles authentication, so users cannot login directly. Our server just receives an SSO token (which comes appropriately signed so that we verify its integrity). We also enforce security at the transport layer for all requests. What I'd like to do

Why CORS on Images with HTML Canvas?

由 倾然丶 夕夏残阳落幕 提交于 2019-12-29 07:03:53
问题 Recently, I spent a bit of time researching a solution to a rather common problem in web development- I was dealing with logos middle-aligned on a transparent background, but having to place text below them, it would then appear as though the amount of whitespace between the text and the image shifts from page to page. After a bit of research, I discovered I could re-align the images bottom-left using a canvas, and the solution worked beautifully... at least until I integrated the solution
