I am trying to change the file name of the pdf generated by the npm module html-pdf.
The issue is I do not want to save a copy of the pdf, just stream it to an email service ( mailgun) and then send it off. I have everything working but when I receive the email the file has a default name that I want to change. Does anyone have any experience trying to do this?
Thanks
var pdf = require('html-pdf');
var Mailgun = require('mailgun-js');
pdf.create(result).toStream(function(err, stream) {
var self = this;
if (err) return console.log(err);
//set mailgun parameters
var mail_data = {
from: 'emailtosendto#email.com',
to: 'sendingemail#email.com',
subject: 'subject line',
html: result,
attachment: stream
}
//send email
mailgun.messages().send(mail_data, function (err, body) {
if (err) {
res.render('error', { error : err});
console.log("got an error: ", err);
}
else {
console.log(body);
res.send('ok');
}
});
});
var pdf = require('html-pdf');
var Mailgun = require('mailgun-js');
pdf.create(result).toBuffer(function(err, buffer) {
var self = this;
if (err) return console.log(err);
var attch = new mailgun.Attachment({data: buffer, filename: 'myattach.pdf'});
//set mailgun parameters
var mail_data = {
from: 'emailtosendto#email.com',
to: 'sendingemail#email.com',
subject: 'subject line',
html: result,
attachment: attch
}
//send email
mailgun.messages().send(mail_data, function (err, body) {
if (err) {
res.render('error', { error : err});
console.log("got an error: ", err);
}
else {
console.log(body);
res.send('ok');
}
});
});

I have a very similar problem with respect to this fellow community contributor. How do i produce multer error message in my postman I followed through the comments made by other users and it was successful! However, when i tried to post a image that is a jpg formatted image( which i managed to do before the editing), it now fails and state that TypeError: Cannot read property 'filename' of undefined.
// multer.js file
successfully setup multer
**please tell me why this error comes on my code and give me a solution**
const multer = require('multer');
const storage = multer.diskStorage({
fileSize: 1024*1024*2,
destination: function (req, file, cb) {
cb(null, './uploads')
},
filename: function (req, file, cb) {
const uniqueSuffix = Date.now() + '-' + Math.round(Math.random() * 1E9)
cb(null, file.fieldname + '-' + uniqueSuffix)
}
})
const filter = function (req, file, cb) {
if (file.mimetype === 'image/jpeg' || file.mimetype === 'image/png') {
cb(null, true);
} else {
cb(new Error('unsupported files'), false)
}
}
var upload = multer({
storage: storage,
limits: {
fileSize: 1024 * 1024 * 5
},
fileFilter : filter
});
module.exports = upload;
//controller.js file
//create function
here's my logic to create a new user
exports.create = (req, res, next) => {
if (!req.body) {
res.status(400).send({ message: "content cannot be empty !!" })
return
}
let data = { name: req.body.name, description: req.body.description, brand_url:
req.body.brand_url, image_file: req.body.file.filename }; getting error here
let sql = "INSERT INTO influencer SET ?";
db.query(sql, data, (err, results) => {
if (err) throw err;
console.log('data inserted succesfully')
res.redirect('/admin');
});
}
//api.js file
//post API
router.post('/api/create', upload.single('image') ,controller.create) //when I am
sending file its throw back error undefined filename
Please make sure you have added enctype="multipart/form-data"
<form action="/api/create" enctype="multipart/form-data" method="post">
I have tested the codes & found the problem.
exports.create = (req, res, next) => {
if (!req.body) {
res.status(400).send({ message: "content cannot be empty !!" })
return
}
let data = {
name: req.body.name,
description: req.body.description,
brand_url: req.body.brand_url,
image_file: req.file.filename
}; // Remove "body", I have tested, it works well.
let sql = "INSERT INTO influencer SET ?";
db.query(sql, data, (err, results) => {
if (err) throw err;
console.log('data inserted succesfully')
res.redirect('/admin');
});
}
I have created an API in Nodejs. I have tried creating a call which returns HTML to display a site in the browser.
My Call looks like this:
router.get('/displayHTML', checkAccessToken, (req, res, next) => {
if (req.query.data === undefined) {
return res.status(900).json({
message: 'Data does not exist'
});
}
Data.find({ data: req.query.data}).exec()
.then(data => {
if (data.length < 1) {
return res.status(400).json({
message: "Nothing found"
});
}
// I need to return HTML here so the user sees something in his browser
return res.status(200).json({
data: data
});
}).catch(error => {
return res.status(500).json({
message: error
});
});
});
Check the fs_library: https://nodejs.org/docs/v0.3.1/api/fs.html
var http = require('http'),
lib = require('fs');
lib.readFile('./page.html', function (err, html) {
if (err) {
throw err;
}
http.createServer(function(request, response) {
response.writeHeader(200, {"Content-Type": "text/html"});
response.write(html);
response.end();
}).listen(8000);
});
I am parsing my json on end but I am still receiving this error.
'use strict';
const http = require('http');
const tools = require('./tools.js');
const server = http.createServer(function(request, response) {
console.log("received " + request.method + " request from " + request.headers.referer)
var body = "";
request.on('error', function(err) {
console.log(err);
}).on('data', function(chunk) {
body += chunk;
}).on('end', function() {
console.log("body " + body);
var data = JSON.parse(body); // trying to parse the json
handleData(data);
});
tools.setHeaders(response);
response.write('message for me');
response.end();
});
server.listen(8569, "192.168.0.14");
console.log('Server running at 192.168.0.14 on port ' + 8569);
Data being sent from the client:
var data = JSON.stringify({
operation: "shutdown",
timeout: 120
});
I successfully receive the json but I am unable to parse it.
Update:
I've updated the code to include the server code in its entirety.
To be perfectly clear, using the following code:
....
}).on('end', function() {
console.log("body " + body);
var json = JSON.parse(body); // trying to parse the json
handleData(json);
});
I get this:
However, this:
....
}).on('end', function() {
console.log("body " + body);
//var json = JSON.parse(body); // trying to parse the json
//handleData(json);
});
produces this
Can we see the server code, please?
Here is a working end-to-end example which is (more or less) what you are attempting, I believe.
"use strict";
const http = require('http');
/********************
Server Code
********************/
let data = {
operation: 'shutdown',
timeout: 120
};
const server = http.createServer((req, res) => {
res.writeHead(200, { 'Content-Type': 'application/json' });
res.write(JSON.stringify(data));
res.end();
});
server.listen(8888);
/********************
Client Code
********************/
let options = {
hostname: 'localhost',
port: 8888,
path: '/',
method: 'POST',
headers: {
'Accept': 'application/json'
}
};
let req = http.request(options, res => {
let buffer = '';
res.on('data', chunk => {
buffer += chunk;
});
res.on('end', () => {
let obj = JSON.parse(buffer);
console.log(obj);
// do whatever else with obj
});
});
req.on('error', err => {
console.error('Error with request:', err);
});
req.end(); // send the request.
It turns out that as this is a cross-origin(cors) request, it was trying to parse the data sent in the preflighted request.
I simply had to add an if to catch this
....
}).on('end', function() {
if (request.method !== 'OPTIONS') {
var data = JSON.parse(body);
handleData(data);
}
});
Further reading if you're interested: HTTP access control (CORS)
Put the identifiers in quotes.
{
"operation": "shutdown",
"timeout": 120
}

I want to create the rest api using node.js and mongodb
I am entering all the details and trying it to store it in the mongodb database.

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var BearSchema = new Schema({
name: String,
email: String
});
module.exports = mongoose.model('Bear', BearSchema);
I am trying it to save the name and the email in the mongodb database but only _id is created instead of name, email.
Here is the result:-
[
{
"_id": "567f1f92db24304013000001",
"__v": 0
},
{
"_id": "567f2765db24304013000002",
"__v": 0
}
]
Can anybody tell me why the data are not getting saved in the database.
Please kindly help.
Thanks in Advance.
I think your POST request is not good, so I made this simple script to check it out:
var XHR = (function() {
var _xhr = (function() {
try {
return new(this.XMLHttpRequest || ActiveXObject)('MSXML2.XMLHTTP.3.0');
} catch (e) {}
})();
return function(method, url, params, callback) {
_xhr.onreadystatechange = function() {
if (_xhr.readyState == 4) {
var _response;
try {
_response = JSON.parse(_xhr.response);
} catch (e) {
_response = _xhr.responseText;
}
if (_xhr.status != 200) {
// catch an error
console.error('error', response);
} else {
if (callback) {
callback(_response);
} else {
// deal with it
}
}
}
}
if (!params) {
params = JSON.stringify({});
} else {
params = JSON.stringify(params);
}
_xhr.open(method, url, true);
// just json in this case
_xhr.setRequestHeader("Content-type", "application/json;charset=UTF-8");
_xhr.send(params);
};
})();
fire it up in browser's console, like this
XHR('POST','api/bears', { name:'yogi', email:'yogi#bears.com'}, function(){ console.log(arguments) });
and your record will be saved.
{ "_id" : ObjectId("567e875d068748ee5effb6e0"), "email" : "yogi#bears.com" "name" : "yogi", "__v" : 0 }
Long story short - your code is okay, your POST is not.
I am trying to get JSON from an API and store it into a MongoDB database.
Obviously, it doesn't work. My app seems to hang around the point where I try to save the data to the database. Please advise what to do.
Here's my code:
var express = require('express');
var router = express.Router();
var http = require('http');
var mongo = require('mongoskin');
var db = mongo.db("mongodb://localhost:27017/zak", {native_parser : true});
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
var site = 'http://www.vsechnyzakazky.cz/api/v1/zakazka/?format=json&limit=2';
function getData(cb) {
http.get(site, function(res) {
// explicitly treat incoming data as utf8 (avoids issues with multi-byte chars)
res.setEncoding('utf8');
// incrementally capture the incoming response body
var body = '';
res.on('data', function(d) {
body += d;
});
// do whatever we want with the response once it's done
res.on('end', function() {
try {
var parsed = JSON.parse(body);
} catch (err) {
console.error('Unable to parse response as JSON', err);
return cb(err);
}
// pass the relevant data back to the callback
cb(
parsed.objects
);
});
}).on('error', function(err) {
// handle errors with the request itself
console.error('Error with the request:', err.message);
cb(err);
});
}
function writeData (data, allGood){
// couple of visual checks if all looking good before writing to db
console.log('writing');
console.log(typeof data);
console.log(data);
db.collection('zakazky').save(data, function(error, record){
if (error) throw error;
console.log("data saved");
});
}
function allGood(){console.log('all done');}
getData(writeData);
// ---------------------
module.exports = router;
You are calling the save() instead of insert(). Change this part and it will work:
// this should call insert, not save
db.collection('zakazky').insert(data, function(error, record){
if (error) throw error;
console.log("data saved");
});
