javascript Windows Edge 并打开一个 blob url

Windows Edge and opening a blob url

提问by Technicolour

I'm getting some odd results when trying to open a new window with a blob url in Windows Edge (20.10240.16384, which is the version in the IE11 VM supplied by Microsoft).

尝试在 Windows Edge（20.10240.16384，这是 Microsoft 提供的 IE11 VM 中的版本）中打开一个带有 blob url 的新窗口时，我得到了一些奇怪的结果。

var xhr = new XMLHttpRequest();
xhr.open('POST', sourceUrl, true);
xhr.responseType = 'blob';

xhr.onload = function(e,form) {
    if (this.status == 200) {
        var blob = this.response;
        var url = window.URL.createObjectURL(blob);
        var w = window.open(url);
    }
}

On the line

在线上

var w = window.open(url);

I'm getting an "Access is denied" error which looks to be tied up with CORS ,which makes sense a little as it's not technically the same domain. However a BLOB url doesn't technically have a domain?

我收到一个“访问被拒绝”错误，它看起来与 CORS 相关，这有点道理，因为它在技术上不是同一个域。但是，BLOB url 在技术上没有域？

Is this a bug in Edge? Or am I doing something not quite right? This code works in IE, Chrome etc.

这是Edge中的错误吗？还是我做错了什么？此代码适用于 IE、Chrome 等。

I found out the solution on both IE and Edge.

我在 IE 和 Edge 上都找到了解决方案。

if (window.navigator && window.navigator.msSaveOrOpenBlob) {
    window.navigator.msSaveOrOpenBlob(blob);  
 }
 else {
     var objectUrl = URL.createObjectURL(blob);
      window.open(objectUrl);  
}
