Chrome MJPEG CORS“无效响应”当img.crossOrigin =“匿名” [英] Chrome MJPEG CORS "invalid response" when img.crossOrigin="Anonymous"
问题描述
来源http://192.168.1.67:5555的图片已被跨源资源共享政策阻止加载：响应无效。因此，不允许访问原始http://127.0.0.1:8000。
我需要允许此MJPEG流的交叉因为用户必须能够使用按钮捕获图像，并且没有CORS画布被污染。
I need to allow cross origin for this MJPEG stream as the user must be able to capture the image with a button and without CORS the canvas is tainted.
我在FF和Chrome中遇到这个问题不同的视频源，因为它不支持MJPEG）。
I'm struggling with this issue in FF and Chrome (IE uses a different video source as it doesn't support MJPEG).
我的服务器还返回 Access-Control-Allow-Origin： code>。在设置 img.crossOrigin =Anonymous; 之后，在Javascript中设置图像 src >。
如果我删除 crossOrigin =Anonymous，流载入，但我得到了污染的画布错误。
My server also returns the Access-Control-Allow-Origin: * when serving the page. The image src is being set in Javascript (if that could be related) after setting img.crossOrigin = "Anonymous";.
If i remove the crossOrigin="Anonymous", the stream loads but i get the tainted canvas error.
感谢

推荐答案
使用此命令运行Chrome chrome .exe --disable-web-security 应该摆脱跨源的问题
run your chrome with this command chrome.exe --disable-web-security should get rid of the cross-origin problems
我有一个chrome快捷方式，这是目标
I have a chrome shortcut and this is the target for it:
C：\Program Files（x86）\Google\Chrome\Application\chrome.exe -disable-web-security
