问题 when i tried to convert image url to base64 am getting CORS issue. Not sure what exactly need to do to get rid of this CORS issue my code look like this function toDataURL(url, callback) { var xhr = new XMLHttpRequest(); xhr.onload = function() { var reader = new FileReader(); reader.onloadend = function() { callback(reader.result); } reader.readAsDataURL(xhr.response); }; xhr.open('GET', url); xhr.responseType = 'blob'; xhr.send(); } toDataURL('https://www.dropbox.com/******/gradient-test

问题 Apparently, I have completely misunderstood its semantics. I thought of something like this: A client downloads javascript code MyCode.js from http://siteA - the origin . The response header of MyCode.js contains Access-Control-Allow-Origin: http://siteB , which I thought meant that MyCode.js was allowed to make cross-origin references to the site B. The client triggers some functionality of MyCode.js, which in turn make requests to http://siteB , which should be fine, despite being cross

问题 I'm trying to do a CORS GET that sends the cookie along with it. I've set all the headers ( access-control-allow-origin , access-control-allow-credentials , access-control-allow-headers ) in the server and am using withCredentials: true and crossDomain: true in the jquery ajax request. Everything works when I tell my browser to allow third-party cookies. Is there any way to do this without forcing visitors to allow third party cookies? I've even tried redirecting the user and redirecting back

问题 I have a self-certificate for apache for https://example.test & https://m.example.test When browsing https://m.example.test cookies are set to the base domain '.example.test' using php 'session.cookie_domain'. This DOES work in Chrome, Firefox or Safari up-to-version-12. However, it does not work anymore in Safari 13 (iOS 13 or Catalina). What's even more strange is that the cookie is still set to the base domain on Safari 13 with my production machine for https://example.COM & https://m

问题 I should make cross domain API with Symfony. There is some bundle for that? I have tried FOS Rest Bundle but did not seem have solved my problem. 回答1: I advise you to use NelmioCorsBundle: https://github.com/nelmio/NelmioCorsBundle This bundle allows you to send Cross-Origin Resource Sharing headers with ACL-style per-URL configuration. Is very useful for CORS problem 回答2: I'm not sure that's the right way, but I resolved for me: 1) Create new event subscriber (like ResponseSubscriber ) 2)

问题 I am on a website https://aaa.shared.com . This website (call it A ) sends an xhr request to url https://zzz.shared.com/some/path (website Z ) and receives a response with the following headers: access-control-allow-credentials: true access-control-allow-origin: aaa.shared.com set-cookie: foo=bar; expires=Fri, 01 Jan 2100 00:00:00 GMT; path=/; secure; samesite=none; httponly (I followed answer on this question to add access-control headers) Now, what I would expect is that whenever I am on
