AngularJS: download pdf file from the server
- by Bartosz Bialecki
I want to download a pdf file from the web server using $http. I use this code which works great, my file only is save as a html file, but when I open it it is opened as pdf but in the browser. I tested it on Chrome 36, Firefox 31 and Opera 23.
This is my angularjs code (based on this code):
UserService.downloadInvoice(hash).success(function (data, status, headers) {
var filename,
octetStreamMime = "application/octet-stream",
contentType;
// Get the headers
headers = headers();
if (!filename) {
filename = headers["x-filename"] || 'invoice.pdf';
}
// Determine the content type from the header or default to "application/octet-stream"
contentType = headers["content-type"] || octetStreamMime;
if (navigator.msSaveBlob) {
var blob = new Blob([data], { type: contentType });
navigator.msSaveBlob(blob, filename);
} else {
var urlCreator = window.URL || window.webkitURL || window.mozURL || window.msURL;
if (urlCreator) {
// Try to use a download link
var link = document.createElement("a");
if ("download" in link) {
// Prepare a blob URL
var blob = new Blob([data], { type: contentType });
var url = urlCreator.createObjectURL(blob);
$window.saveAs(blob, filename);
return;
link.setAttribute("href", url);
link.setAttribute("download", filename);
// Simulate clicking the download link
var event = document.createEvent('MouseEvents');
event.initMouseEvent('click', true, true, window, 1, 0, 0, 0, 0, false, false, false, false, 0, null);
link.dispatchEvent(event);
} else {
// Prepare a blob URL
// Use application/octet-stream when using window.location to force download
var blob = new Blob([data], { type: octetStreamMime });
var url = urlCreator.createObjectURL(blob);
$window.location = url;
}
}
}
}).error(function (response) {
$log.debug(response);
});
On my server I use Laravel and this is my response:
$headers = array(
'Content-Type' => $contentType,
'Content-Length' => strlen($data),
'Content-Disposition' => $contentDisposition
);
return Response::make($data, 200, $headers);
where $contentType is application/pdf and $contentDisposition is attachment; filename=" . basename($fileName) . '"'
$filename - e.g. 59005-57123123.PDF
My response headers:
Cache-Control:no-cache
Connection:Keep-Alive
Content-Disposition:attachment; filename="159005-57123123.PDF"
Content-Length:249403
Content-Type:application/pdf
Date:Mon, 25 Aug 2014 15:56:43 GMT
Keep-Alive:timeout=3, max=1
What am I doing wrong?
