I am a beginner for MEAN stack. I want to download and display a pdf file to the client. For that my server side script as under:
app.get("/pdf", function(req, res)
{
var file = __dirname + '/try.pdf';
res.download(file, function (err)
{
if (err) {
console.log("Error " + err);
} else {
console.log("Success"); // server shows success but file is not downloaded to client
}
res.end();
}
);
}
);
After starting server when I give command localhost/pdf in browser the file is downloaded. But, when I connect to server through index page and attach this module to ng-click event of a button, server shows success but the file is not downloaded to client. My angularJS code is as under which also displays both success and then clause message:
app.controller('showPDF', function($scope, $http)
{
$scope.pdfShow = function()
{
alert("Inside pdfShow");
$http.get("/pdf" ).
success(function(response){alert("PDF Success")}).
error(function(error, status){alert("PDF Error " + error + " status " + status); }).
then(function(response){alert("PDF then clause ")})
}
}
);
<button ng-controller="showPDF" ng-click="pdfShow()">Show PDF file </button>
Is there any mistake I am doing? Please guide me.
Thanks.
