解決canvas跨域問題(圖片,視頻資源跨域)

 

添加跨域條件   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' ; //可選值：anonymous，*  

img.src = 'http://....' ;

 

或者是HTML中   <img src="" id="" crossorigin="anonymous">

 

視頻的話同上，<video width="320" height="240" controls="controls"  crossorigin="anonymous"></video>

如果視頻 video.crossOrigin = 'anonymous';  報錯的話，可以在標簽上面加該屬性。
