Question

What i am trying to do ::
I am trying to move the uploaded file to /public/images
My request::
My app.js code
var express=require('express');
var mysql=require('mysql');
var fs=require('fs');
var http=require('http');
var crypto=require('crypto');
var app=express();
var connection=mysql.createConnection({
host:'localhost',
user:'******',
password:'******',
database:'*********'
});
connection.connect();
app.set('port',process.env.PORT||7002);
app.use(express.bodyParser());
app.post('/Details/',function(req,res){
var file_name=req.files.key.originalFilename;
console.log(file_name);
crypto.randomBytes(8, function(ex, buf) {
var array = req.files.key.originalFilename.split('.');
var type = array[array.length - 1];
var name = buf.toString('hex') + '.' + type;
fs.rename(req.files.key.path, './public/images/' + name, function(e) {
next(e, name);
});
});
});
http.createServer(app).listen(app.get('port'),function(){
console.log('Express server listening on port'+app.get('port'));
});
Error i am facing::
next(e, name)......... "next" not defined
How to resolve this ?

Answer 1

What exactly do you want to do? I think that instead of calling next, you want to generate a response back to the client.
So instead of this:
next(e, name);
Do this:
if (e) {
res.send(500, e.message);
} else {
res.send(WHATEVER_YOU_WANT_TO_SEND_AS_RESPONSE);
}
If you really want to call next, you need to add it to the callback function's argument list:
app.post('/Details/', function(req, res, next) { ...
