javascript - Corrupted download in AngularJs app -

i trying download file using filesaver.js, corrupted file whenever hit download button.

app backed php rest service, , using curl command line confirms rest working ok.

here last version of pseudo-code use downloading:

// let str data received $http promise // code run in "then" callback  var arr= new uint8array(str.length); for(var i=0; i<str.length; i++) {     arr[b]=str.charcodeat(i); }; var blob = new blob([arr], {type: 'application/octet-stream'}); saveas(blob, "afilename"); 

it corrupts file.

i tried without applying uint8array, , giving str directly blob. guessed, failed too.

i writing server , client myself, can change in them. thing want handle downloads client-side, , can't redirect users file url download it, because rest needs authentication , token lives within angular app. not choice change server handle file downloads without authentication.

the rest has urls /files/:id when accessed, gives file content regular http file download (tested curl said above). $http problem? somehow forcing kind of encoding or assumptions on received data. don't have experience in angular, anyway.

i have found problem. me :)

i had specify responsetype: "arraybuffer" $http give str directly blob.

fixed code

// let str data received $http promise // code run in "then" callback // make sure specify "responsetype: "arraybuffer"" $http  var blob = new blob([str], {type: 'application/octet-stream'}); saveas(blob, "afilename"); 

i changing responsetype in wrong place.
