上传预览图片突然报错Tainted canvases may not be exported #3186

报错内容 : Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported 上传时,不能预览图片了.服务器就在本地,上传目录也是本地. 一直以来都正常的,突然就报错了,我还以为代码出问题了.下载了DEMO测试.还是报错.一番查询.认为和跨域方面有关 在chrome中chrome://flags/#block-insecure-private-network-requests 禁用掉.重启浏览器后,上传恢复正常.. 奇怪的是 chrome中这个设置随后我又恢复成默认.现在网站上传依然正常...
