How to read RAW JSON in Angular JS from HTTP get method, when response type is arraybuffer?

Instead of expecting arraybuffer why not expect application/json all the time, then when you return your data that's supposed to create your pdf, do a base64 of the data, put it in a json object and return it to the client

Even when you throw an exception you still expect JSON. Your response from server side could be something like:

{    responseCode: // your response code according to whether the request is success or not,    responseMessage: // success or fail    data: // your base64 encoded pdf data(the data that if the request is successful will be returned), note it will be returned as a normal string} // I'm hoping you know how to base64 encode data

Then in your client side(Javascript), perform an if

if(data.responseCode == //errorCode) {    alert(data.responseMessage);} else {    // Unpack data    var myPdfData = // base64 decode(data.data)    // Do logic to create and open/download file}

You don't even need to decode the data, you just create a blob object, then trigger a download from the blob

If the responsetype is arraybuffer, to view it, you should convert it into a blob and create a objectUrl from that blob, and the download it or open in a new tab/browser window to view it.

Js:

$http.get('your/api/url').then(function(response) {var blob = new Blob([response.data], { type: 'application/pdf' });    var downloadUrl = URL.createObjectURL(blob);    $timeout(function () {        var link = document.createElement('a');        link.download = 'SOME_FILE_NAME'+ '.pdf';        link.href = downloadUrl;        link.click();    }, 100);}, function(errorResponse){    alert(errorResponse.error.message);});
