最近无法在 IE11/10/9 上查看 PDF

PDF cannot be seen on IE11/10/9 recently

我是一家公司的网络开发人员。
从这周开始,我周围的所有同事和网络客户都不能再打开嵌入的pdf数据了。
我们传输数据协议的方式,data:application/pdf例子可以在plunkerhttp://embed.plnkr.co/Bjkypkht4RjIWE1AyFP0/index.html
中找到 简而言之,我们将数据放入data:application/pdf,并使用window.open()方法在浏览器中打开pdf二进制数据。
此功能在本周之前正常工作,实际上它已经在带有 pdf 附加组件或查看器插件的 IE/Firefox/Chrome 浏览器中工作了将近一年。

但是这周开始,所有IE版本都不能用了,报错如下,谁能帮我看看是什么原因?

Error displayed by IE:
The webpage cannot be displayed
Most likely cause:
Some content or files on this webpage require a program that you don't have installed.


请不要告诉我重置IE或enable/disable IE,这些方法我们都试过了,但都没有用。谢谢

这是我使用 javascript 验证过的代码片段。

            //create a Blob with an array and the optional dictionary object.
            var TEST_PDF_DATA = data;
            var byteCharacters = atob(TEST_PDF_DATA);

            var charCodeFromCharacter = function(c) { return c.charCodeAt(0); }
            var byteArrays = [];
            for (var offset = 0; offset < byteCharacters.length; offset += 1000)
            {
                var slice = byteCharacters.slice(offset, offset + 1000);
                var byteNumbers = Array.prototype.map.call(slice, charCodeFromCharacter);
                byteArrays.push(new Uint8Array(byteNumbers));
            }

            var blob1 = new Blob(
                byteArrays, //array
                { type: "application/pdf"} //dictionary object
            );

            //create a second blob that uses the first blob in its array
            var blob2 = new Blob([blob1, "Those who understand binary and those who don't."]);

            // Save the blob2 content to a file, giving both "Save" *and* "Open" options
            window.navigator.msSaveOrOpenBlob(blob2, 'msSaveBlobOrOpenBlob_testFile.pdf');
            alert('File saved using msSaveOrOpenBlob() - note the two "Open" and "Save" buttons below.');
