在IE 11中显示二进制文件(pdf) [英] Displaying binary file (pdf) in IE 11

问题描述

我正在尝试使用本文中建议的方法显示二进制文件

I am trying to display a binary file using the method suggested in this post AngularJS: Display blob (.pdf) in an angular app. This is working nicely in Chrome and FF, but IE 11 is giving me "Error: Access Denied". Does anyone know if it has something to do with the Blob object and can point me in the right direction? Here is my js code:

$http.get(baseUrl + apiUrl, { responseType: 'arraybuffer' })
          .success(function (response) {                  
             var file = new Blob([response], { type: 'application/pdf' });
             var fileURL = URL.createObjectURL(file);
             $scope.pdfContent = $sce.trustAsResourceUrl(fileURL);
           })
           .error(function () {                        
           });

和我的html:

<div ng-controller="PDFController" class="modal fade" id="pdfModal" tabindex="-1" role="dialog" aria-hidden="true">
<div class="modal-dialog modal-lg">
    <div class="modal-content" onloadstart="">
        <object data="{{pdfContent}}"  type="application/pdf" style="width:100%; height:1000px" />
    </div>
</div>

推荐答案

IE 11阻止显示blob，您需要使用以下内容:

IE 11 blocks display of blob, you need to use the following:

                    var byteArray = new Uint8Array(someByteArray);
                var blob = new Blob([byteArray], { type: 'application/pdf' });
                if (window.navigator && window.navigator.msSaveOrOpenBlob) {
                    window.navigator.msSaveOrOpenBlob(blob);
                }
                else {
                    var objectUrl = URL.createObjectURL(blob);
                    window.open(objectUrl);
                }
