Tuve el mismo problema y dediqué muchas horas a buscar diferentes soluciones, y ahora me uno a todos los comentarios de esta publicación, espero que sea de ayuda, mi respuesta fue probada correctamente en Internet Explorer 11, Chrome y FireFox.
HTML:
<a href="#" class="btn btn-default" file-name="'fileName.extension'" ng-click="getFile()" file-download="myBlobObject"><i class="fa fa-file-excel-o"></i></a>
DIRECTIVA:
directive('fileDownload',function(){
return{
restrict:'A',
scope:{
fileDownload:'=',
fileName:'=',
},
link:function(scope,elem,atrs){
scope.$watch('fileDownload',function(newValue, oldValue){
if(newValue!=undefined && newValue!=null){
console.debug('Downloading a new file');
var isFirefox = typeof InstallTrigger !== 'undefined';
var isSafari = Object.prototype.toString.call(window.HTMLElement).indexOf('Constructor') > 0;
var isIE = /*@cc_on!@*/false || !!document.documentMode;
var isEdge = !isIE && !!window.StyleMedia;
var isChrome = !!window.chrome && !!window.chrome.webstore;
var isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
var isBlink = (isChrome || isOpera) && !!window.CSS;
if(isFirefox || isIE || isChrome){
if(isChrome){
console.log('Manage Google Chrome download');
var url = window.URL || window.webkitURL;
var fileURL = url.createObjectURL(scope.fileDownload);
var downloadLink = angular.element('<a></a>');//create a new <a> tag element
downloadLink.attr('href',fileURL);
downloadLink.attr('download',scope.fileName);
downloadLink.attr('target','_self');
downloadLink[0].click();//call click function
url.revokeObjectURL(fileURL);//revoke the object from URL
}
if(isIE){
console.log('Manage IE download>10');
window.navigator.msSaveOrOpenBlob(scope.fileDownload,scope.fileName);
}
if(isFirefox){
console.log('Manage Mozilla Firefox download');
var url = window.URL || window.webkitURL;
var fileURL = url.createObjectURL(scope.fileDownload);
var a=elem[0];//recover the <a> tag from directive
a.href=fileURL;
a.download=scope.fileName;
a.target='_self';
a.click();//we call click function
}
}else{
alert('SORRY YOUR BROWSER IS NOT COMPATIBLE');
}
}
});
}
}
})
EN CONTROLADOR:
$scope.myBlobObject=undefined;
$scope.getFile=function(){
console.log('download started, you can show a wating animation');
serviceAsPromise.getStream({param1:'data1',param1:'data2', ...})
.then(function(data){//is important that the data was returned as Aray Buffer
console.log('Stream download complete, stop animation!');
$scope.myBlobObject=new Blob([data],{ type:'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'});
},function(fail){
console.log('Download Error, stop animation and show error message');
$scope.myBlobObject=[];
});
};
EN SERVICIO:
function getStream(params){
console.log("RUNNING");
var deferred = $q.defer();
$http({
url:'../downloadURL/',
method:"PUT",//you can use also GET or POST
data:params,
headers:{'Content-type': 'application/json'},
responseType : 'arraybuffer',//THIS IS IMPORTANT
})
.success(function (data) {
console.debug("SUCCESS");
deferred.resolve(data);
}).error(function (data) {
console.error("ERROR");
deferred.reject(data);
});
return deferred.promise;
};
BACKEND (en PRIMAVERA):
@RequestMapping(value = "/downloadURL/", method = RequestMethod.PUT)
public void downloadExcel(HttpServletResponse response,
@RequestBody Map<String,String> spParams
) throws IOException {
OutputStream outStream=null;
outStream = response.getOutputStream();//is important manage the exceptions here
ObjectThatWritesOnOutputStream myWriter= new ObjectThatWritesOnOutputStream();// note that this object doesn exist on JAVA,
ObjectThatWritesOnOutputStream.write(outStream);//you can configure more things here
outStream.flush();
return;
}
