Method sendVoice() Telegram bot - the file is empty

I have this JavaScript code:
bot.sendVoice(chatId, 'C:/Users/a.repetto/Desktop/repettobot/hello_world.ogg', {
disable_notification: true,
reply_to_message_id: msg.message_id
}).then(function () {
// reply sent!
});
The file exists and contain the audio, but when I try to run the entire code I get this error:
""error_code":400,"description":"Bad Request: File must be non-empty "
I have also tried with sendAudio but this also doesn't work.
Edit 1: To be more specific.
If I write a script with only 'sendAudio' or 'sendVoice', the file is sent correctly to Telegram. But if I use this blcok of script, the file results empty:
var Bot = require('node-telegram-bot-api');
var watson = require('watson-developer-cloud');
var request = require('request');
var fs = require('fs');
function sleep (time) {
return new Promise((resolve) => setTimeout(resolve, time));
}
var speech_to_text = watson.speech_to_text({
username: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXX, //username from VCAPSERVICES
password: 'XXXXXXXX', //password from VCAP SERVICES
version: 'v1',
url: 'https://stream.watsonplatform.net/speech-to-text/api'
});
var language_translation = watson.language_translator({
username: 'XXXXXXXXXXXXXXXXXX',
password: 'XXXXXXXX',
version: 'v2'
});
var text_to_speech = watson.text_to_speech({
username: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
password: 'XXXXXXXXXX',
version: 'v1'
});
var params = {
model: 'en-US_BroadbandModel', //you can change the language here
content_type: 'audio/ogg;codecs=opus',
continuous: true,
interim_results: false
};
var bot = new Bot('XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', {polling: true }); //token generated by the bot you created
bot.on('message', function (msg) {
if(msg['voice']){ return onVoiceMessage(msg); }
});
function onVoiceMessage(msg) {
var chatId = msg.chat.id;
bot.getFileLink(msg.voice.file_id).then(function(link) {
var recognizeStream = speech_to_text.createRecognizeStream(params);
recognizeStream.setEncoding('utf8');
recognizeStream.on('results', function(data) {
var result = data.results[0].alternatives[0].transcript;
var c = result;
console.log("testo: " + result);
bot.sendMessage(chatId, result, {
disable_notification: true,
reply_to_message_id: msg.message_id
}).then(function(){})
language_translation.translate({
text: result,
source: 'en',
target: 'it'
}, function(err,translation) {
if (err) {
console.log(err);
}
else {
var trad = translation.translations[0].translation;
console.log("traduzione: " + trad + "\n")
}
bot.sendMessage(chatId, trad, {
disable_notification: true,
reply_to_message_id: msg.message_id
}).then(function(){})
var params1 = {
text: trad,
voice: 'it-IT_FrancescaVoice',
accept: 'audio/ogg;codecs=opus'
}
bot.sendVoice(chatId, text_to_speech.synthesize(params1), {
disable_notification: true,
reply_to_message_id: msg.message_id
}).then(function(promise){console.log(promise)})
})
})
request(link).pipe(recognizeStream);
})
}

Telegram cannot send file from your PC. First upload your files and then replace local address with web address. Other way is send file to telegram bot and get file_id (use getUpdate method) and put file_id in your code.

Downloading multiple files using AngularJS and storing in path

I am new to Angular,I have a scenario, where I need to download multiple files at the same time. My files are stored in GridFS. I am able to download the files, but for example a pdf is blank. The contentType stored in gridFS is "contentType": "binary/octet-stream", Am I missing out on anything?
My Jade code is
tr(ng-repeat='row in displayedCollection')
td {{ row.Name}}
td {{ row.email}}
td
button.btn.btn-info(type='button',ng-click="downloadDocuments(row.documentsSubmitted)" download) Download Documents
My controller code is
$scope.downloadDocuments = function (row) {
angular.forEach(row, function (value, key) {
var fileToDownload = value.id + "," + 'TrainingPartnerAddingTrainingCenter';
$http.get('/downloadDocuments/' + fileToDownload).success(function (result, status, headers, config) {
var _contentType = (headers('Content-Type'));
var _fileName = headers('FileName');
var blob = new Blob([ result ], { type : _contentType });
var url = (window.URL || window.webkitURL).createObjectURL(blob);
var anchor = angular.element('<a/>');
anchor.attr({
href : url,
target : '_blank',
download : _fileName
})[0].click();
});
});
};
my node.js code is as follows
exports.downloadDocument = function (req, res) {
var paramData = req.params.fileToDownload.split(',');
var role = req.session.user.role;
var conn = mongoose.connection;
var gfs = Grid(conn.db, mongoose.mongo);
routesLogger.logInfo(role, "downloadDocument", "START");
gfs.findOne({_id: paramData[0], root: paramData[1]}, function (err, file) {
if (err) {
routesLogger.logError(role, "downloadDocument", err);
return res.status(400).send(err);
}
else if (!file) {
routesLogger.logError(role, "downloadDocument", "No File Found for download");
return res.status(404).send('Error on the database looking for the file.');
}
else {
res.set('Content-Type', file.contentType);
res.set('Content-Disposition', 'attachment; filename="' + file.filename + '"');
var readstream = gfs.createReadStream({
_id: paramData[0],
root: paramData[1]
});
readstream.on("error", function (err) {
routesLogger.logError(role, "downloadDocument", err);
res.end();
});
readstream.pipe(res);
routesLogger.logInfo(role, "downloadDocument", "END");
}
});
};

So the mistake I was doing was not adding the parameter { responseType: 'arraybuffer' }. I found the answer in this link
AngularJS: Display blob (.pdf) in an angular app
$http.get('/downloadDocuments/' + fileToDownload,{ responseType: 'arraybuffer' }).success(function (result, status, headers, config) {
console.log(headers('Content-Type'));
var _contentType = (headers('Content-Type'));
var _fileName = headers('FileName');
var blob = new Blob([result], {type: _contentType });
saveAs(blob, _fileName);

Sequelize send picture from blob

Right now I create a new url based on rowid and stream the picture back using fs. Below is my code that works right now.
This saves the picture from the blob pulled from the database.
exports.picFileSave = function (name, data) {
try{
// Query the entry
stats = fs.lstatSync(name);
// Is it a directory?
if (stats.isFile()) {
//do nothing;
}
} catch (e) {
var wstream = fs.createWriteStream(name);
wstream.write(data);
wstream.end();
}
};
This function gets the picture filename and sends it back
exports.getLocBg = function (rowid, callback) {
var filename = "tmp/loc/" + rowid + ".png";
try{
// Query the entry
stats = fs.lstatSync(filename);
// Is it a directory?
if (stats.isFile()) {
callback(filename);
}
} catch (e) {
locationdb.location
.findOne({where: {id: rowid}})
.then(function (locations) {
var wstream = fs.createWriteStream(filename);
wstream.write(locations.locationBackground);
wstream.end();
callback(filename);
});
}
};
This is simply the route that connects the client to the server
app.get('/mobile/locations/locbg/:rowid', function (req, res) {
var options = {
root: "./",
dotfiles: 'deny',
headers: {
'x-timestamp': Date.now(),
'x-sent': true
}
};
var rowid = req.params.rowid;
location.getLocBg(rowid, function (callback) {
res.sendFile(callback, options, function (err) {
if (err) {
console.log(err);
res.status(err.status).end();
}
else {
console.log('Sent:', callback);
}
});
});
});
I want to be able to simply pull the blob from the database and send the picture back without writing a file and sending that back. How would I go about this?

angular js file upload using http post method

I am tring to upload a file using angular $http method to node backend
I want to upload the form with additional form fields.
This is my code
var data = new FormData();
data.append('title', 'sometitle');
data.append('uploadedFile', $scope.uploadedFile);
FileService.upload(url, data, function(data, status) {
if(status===HTTP_OK) {
$scope.uploadSuccess = true;
$scope.showUploadProgressBar = false;
} else {
// error occured
console.log(data);
}
});
FileService
FileService.upload = function(url, data, callback) {
$http({
method : 'POST',
url : url,
data : data,
headers: {'Content-Type': undefined },
transformRequest: angular.identity
}).success(function(data, status) {
callback(data, callback);
}).error(function(data, status) {
callback(data, status);
});
};
I am using node multiparty module for file upload. I am receiving the file correctly. But the field value for title is undefined.
I don't know why title value is undefined
Node.js backend file upload handler
var form;
if(options.uploads.tempDir) {
form = new multiparty.Form({uploadDir : options.root + '/' + options.uploads.tempDir});
} else {
form = new multiparty.Form();
}
form.on('file', function(name, receivedFile) {
var tmpPath = receivedFile.path,
fileName = receivedFile.originalFilename,
targetDirectory = uploadDirectory + '/' + req.params.id,
targetPath = targetDirectory + '/' + fileName,
file = {
filePath : targetPath,
tempPath : tmpPath,
fileName : fileName,
size : receivedFile.size
};
fileUploadStatus.file = file;
// move file
fse.move(tmpPath, targetPath, function(err) {
if(err) {
console.log('Error moving file [ ' + targetPath + ' ] ' + JSON.stringify(err));
}
});
});
form.on('error', function(err) {
fileUploadStatus.err = err;
req.fileUploadStatus = fileUploadStatus;
next();
});
form.on('close', function() {
req.fileUploadStatus = fileUploadStatus;
next();
});
form.on('field', function(name, value) {
console.log('field called');
console.log(name);
console.log(value);
req.body = req.body || {};
req.body[name] = value;
});
// ignoring parts. Implement any other logic here
form.on('part', function(part) {
var out = new stream.Writable();
out._write = function (chunk, encoding, done) {
done(); // Don't do anything with the data
};
part.pipe(out);
});
// parsing form
form.parse(req);
