Why am I getting a 403 error when uploading to S3 from the browser?

问题 So I've tried looking through previous answers on here and nothing seems to be working. I'm using Dropzone, which appears to make an OPTIONS request to get all the allowed CORS related information, but it doesn't seem to be returning properly So from looking in the Chrome dev tools, I have the following Request Headers Host: mybucket.s3.amazonaws.com Connection: keep-alive Pragma: no-cache Cache-Control: no-cache Access-Control-Request-Method: POST Origin: http://localhost:9010 User-Agent:

Cross Origin Resource Sharing (CORS) and Javascript

问题 As an example case let's take this url: http://api.duckduckgo.com/?q=computer&format=json (CORS not enabled on this server!) We can access the contents from this URL from any popular browser as a normal URL, browser has no issues opening this URL nor the server returns any error. A server-side language like PHP/RoR can fetch the contents from this URL without adding any additional headers or special server settings. I used following PHP code and it simply worked. $url='http://api.duckduckgo

问题 This question has been asked a lot, but I just don't understand why this is happening to me. Basically, I have a canvas, and an image, and when I try to do this: var canvas = document.getElementById('somecanvas'); var ctx = canvas.getContext('2d'); var someimage = document.createElement('img'); someimage.setAttribute('src', 'img/someimage.png'); someimage.onload = function(){ ctx.drawImage(someimage, 0, 0, canvas.width, canvas.height); data = ctx.getImageData(0,0,canvas.width,canvas.height);

Safari 13+ iframe blocks CORS cookies
