As mentioned here https://html2canvas.hertzen.com/documentation正如这里提到的https://html2canvas.hertzen.com/documentation
All the images that the script uses need to reside under the same origin for it to be able to read them without the assistance of a proxy.
When you load it from same origin (your second attempt), it works.当您从同一来源（您的第二次尝试）加载它时，它可以工作。 Here is workaround - https://html2canvas.hertzen.com/proxy/这是解决方法 - https://html2canvas.hertzen.com/proxy/
