How to show ldapatuh node jpegPhoto? - node.js

Question

I use ldapauth-fork in node.js to take a user information in ldap but when I try to take a user.jpegPhoto why can't it show this image?
I've tried this:
const jpeg = Buffer.from(user.jpegPhoto, 'binary')
fs.writeFileSync("foto.jpeg", jpeg);
And this:
var img64 = Buffer.from(user.jpegPhoto).toString('base64');
var foto = "<div><img src='data:image/jpeg;base64,"+img64+"'/></div>"
fs.appendFile('index.html', foto, function (err) {
if (err) throw err;
console.log('Saved!');
});
This is all node.js code:
var basicAuth = require('basic-auth');
var LdapAuth = require('ldapauth-fork');
var http = require('http');
var fs = require('fs');
var qs = require('querystring');
var username = "MOCKUSERNAME";
var password = "MOCKPASSWORD";
server = http.createServer( function(req, res) {
if (req.method == 'POST') {
console.log("POST");
var body = '';
req.on('data', function (data) {
body += data;
//console.log(body);
});
req.on('end', function () {
var data = qs.parse(body);
var userDecode = Buffer.from(data.username, 'base64').toString('ascii');
var passDecode = Buffer.from(data.password, 'base64').toString('ascii');
res.setHeader('Access-Control-Allow-Origin', '*');
res.writeHead(200, {'Content-Type':'image/jpeg'});
if (data.username && data.password) {
var options = {
url: 'XXXXXX',
bindDN: 'XXXXX',
bindCredentials: 'XXXXX',
searchBase: 'XXXXX',
includeRaw: true,
searchFilter: '(aoldapkey=*' + userDecode + ')'
// reconnect: true
}
var ldap = new LdapAuth(options);
ldap.authenticate(userDecode, passDecode, function(err, user) {
if (err) {
console.log("login Error: " + err);
res.write(JSON.stringify({ success : false, message : 'Authentication failed', serverError: err }));
res.end('');
} else if(!user.uid) {
console.log("user not found Error: " + err);
res.write(JSON.stringify({ success : false, message :
'Authentication failed, user not found', serverError: err }));
res.end();
} else if(user.uid) {
console.log("success : user "+ user.uid +" found ");
var userJsonObject = {
success : true,
user: {
uid : user.uid,
cn: user.cn,
givenName: user.givenName,
sn: user.sn,
title: user.title,
mobile: user.mobile,
mail: user.mail,
aoJobPosition: user.aoJobPosition,
jpegPhoto: user.jpegPhoto
}
}
//------------------------------dont see the image in index.html
/*var img64 = Buffer.from(user.jpegPhoto).toString('base64');
var foto = "<div><img src='data:image/jpeg;base64,"+img64+"'/>
</div>"
fs.appendFile('index.html', foto, function (err) {
if (err) throw err;
console.log('Saved!');
});*/
//--------------------------------
res.write(JSON.stringify(userJsonObject);
res.end();
}
});
} else {
res.write(JSON.stringify({ success : false, message : 'You must
specify a valid username and password'}));
res.end();
}
});
}
else {
var html = fs.readFileSync('index.html');
res.writeHead(200, {'Content-Type': 'text/html'});
res.end(html);
}
});
server.on('error', function(err) {
console.log("Caught server error: ");
console.log(err.stack);
});
port = 3000;
host = '127.0.0.1';
server.listen(port, host);
console.log('Listening at http://' + host + ':' + port);
This is all node.js code I use ldapauth-fork in node.js to take a user information in ldap but when i try to take a user.jpegPhoto y can´t show this image.
This is index.html :
<div><img src='data:imag/*;base64, 77x73..........3vv70='/></div>
index.html
