解决canvas跨域问题(图片,视频资源跨域)

 
添加跨域条件   crossorigin="anonymous"

 

【Redirect at origin 'http://xxx.xx.com' has been blocked from loading by Cross-Origin Resource Sharing

policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://sub2.xx.com' is therefore not allowed access.】

 

var img = new Image;
img.onload = myLoader;
img.crossOrigin = 'anonymous' ; //可选值:anonymous,*  
img.src = 'http://....' ;

 

或者是HTML中   

 

视频的话同上,

如果视频 video.crossOrigin = 'anonymous';  报错的话,可以在标签上面加该属性。

 

个人博客 :很多好用的 npm 包 , 可以看看  https://gilea.cn/
