Related to Need to open blob/PDF in IE window and Setting window.location or window.open in AngularJS gives "access is denied" in IE 11 .
I need to open a PDF which comes from a byte array in my service:
@RequestMapping("/{dokumentId}")
public ResponseEntity<byte[]> getDoc(@PathVariable Integer docId, HttpServletRequest request, HttpServletResponse response) throws IOException {
byte[] contents = // .. get document
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.parseMediaType("application/pdf"));
headers.add("Content-Disposition", "inline;filename=file");
headers.add("Cache-Control","private, must-revalidate, post-check=0, pre-check=0, max-age=1");
headers.add("Pragma", "no-cache");
headers.setContentLength(contents.length);
return new ResponseEntity<>(contents, headers, HttpStatus.OK);
}
which I'm trying to open in Internet Explorer 11 with the following JS:
$scope.openPdf = function(doc){
var winlogicalname = "document_" + doc.docId;
var winparams = 'dependent=yes,locationbar=no,scrollbars=yes,menubar=yes,resizable,screenX=50,screenY=50,width=850,height=1050';
var ieEDGE = navigator.userAgent.match(/Edge/g);
var ie = navigator.userAgent.match(/.NET/g); // IE 11+
var oldIE = navigator.userAgent.match(/MSIE/g);
if(!ie && !oldIE && !ieEDGE){
// Open PDF in new browser window
var detailWindow = window.open("", winlogicalname, winparams);
}
xxxService.getDoc(doc).success(function(data){
//for browser compatibility
if (ie || oldIE || ieEDGE) {
var blob = new window.Blob([data], { type: 'application/pdf' });
window.navigator.msSaveOrOpenBlob(blob);
} else {
var binaryAsString = ArrayBufferToString(data).replace(/"/g,"");
var pdfAsDataUri = "data:application/pdf;base64," + binaryAsString;
var htmlText = '<embed width=100% height=100% type="application/pdf" src="'+ pdfAsDataUri + '"></embed>';
detailWindow.document.write(htmlText);
detailWindow.document.close();
}
}).error(function(data, status, headers, config){
console.log(data, status, headers, config);
});
};
This works in Chrome and Firefox (opens in new window, constructed directly from binary with <embed>
. However, this way does not seem to work in IE, hence msSaveOrOpenBlob
. But when saving/opening the PDF in IE, I get an error in Adobe Reader: " Adobe Acrobat Reader DC could not open 'file.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).
". When I try to drag and drop the PDF in to IE, it says " File does not begin with '%PDF-'.
".
Any ideas on how to open a PDF in IE11 using either byte array directly or constructing a Blob
?
I changed my web service to this:
byte[] contents = // get contents
response.getOutputStream().write(contents);
response.setContentType("application/pdf");
response.setContentLength(contents.length);
response.addHeader("Content-Disposition", "inline;filename="+filename);
response.addHeader("Cache-Control", "private, must-revalidate, post-check=0, pre-check=0, max-age=1");
response.addHeader("Pragma", "public");
and then consumed on client side with:
Service.getDocument(docId).success(function(data){
var file = new Blob([data], {type: 'application/pdf'});
if(window.navigator.msSaveOrOpenBlob){
window.navigator.msSaveOrOpenBlob(file, name + ".pdf");
} else {
var fileURL = URL.createObjectURL(file);
$scope.renderPDF(fileURL, detailWindow.document.getElementById('canvas'));
}
}
where $scope.renderPDF
uses PDFJS to render the PDF in a new window. Remember to set {responseType:'arraybuffer'})
on the $http.get
(or post
) method.
