Windows Edge并打开一个blob网址 [英] Windows Edge and opening a blob url

问题描述

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

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).

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);
    }
}

在线

var w = window.open(url);

我收到访问被拒绝错误，该错误似乎与CORS捆绑在一起因为它在技术上不是同一个域，所以有点意义。但是BLOB网址在技术上没有域？

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?

这是Edge中的错误吗？或者我做的事情不太对劲？此代码适用于IE，Chrome等。

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

推荐答案

我在IE和Edge上找到了解决方案。

I found out the solution on both IE and Edge.

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