Hello I am trying to retrieve something from the post, and need the rawBody property from the incoming request. How can I retrieve it??
I tried using express.bodyParser() and in my post handler, I was looking for req.rawBody, and it was undefined.
I even tried it with connect.bodyParser(), but I still have no luck with it. I am getting undefined for rawBody.
I was reading on the stackoverflow site saying that they had removed the rawBody functionality, but mentioned that it is a quick fix to add it to our own middleware file. I am a newbie, so I do not have a clue as to how to achieve this. Below is my code snippet.
/**
* Module dependencies.
*/
var express = require('express')
, connect = require('connect')
, routes = require('./routes')
, user = require('./routes/user')
, http = require('http')
, path = require('path');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
//app.use(express.bodyParser());
app.use(connect.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
app.get('/', routes.index);
app.get('/users', user.list);
/**custom stuff**/
app.post('/upload',function(req, res){
console.log(req.header('Content-Type'));
console.log(req.header('Host'));
console.log(req.header('User-Agent'));
console.log(req.rawBody);
console.log(req.body);
res.send("<h1> Hello the response is "+req.body.username);
});
/** end**/
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
Any help with this is much appreciated.
Thank you.
You can use your own middle ware to do this:
app.use(function(req, res, next){
var data = "";
req.on('data', function(chunk){ data += chunk})
req.on('end', function(){
req.rawBody = data;
next();
})
})
// Your route registration:
app.get('/', function(){// whatever...})
app.post('/test', function(req, res){
console.log(req.rawBody);
res.send("your request raw body is:"+req.rawBody);
})
I'm back again :D. After read the connect.bodyParser I've found something: The bodyParser only parse the data which mime type is one of: application/json, application/x-www-form-urlencoded and multipart/form-data. So I think this is another approach, it's not generally elegant but acceptable: When you try to send raw data to server, change the mime type to something different. As your question it's a string, so I choose text/plain as example:
// if the request's mime type is text/plain, read it as raw data
var myRawParser = function(req, res, next){
req.rawData = '';
if(req.header('content-type') == 'text/plain'){
req.on('data', function(chunk){
req.rawData += chunk;
})
req.on('end', function(){
next();
})
} else {
next();
}
}
// ...
app.use(myRawParser);
app.use(express.bodyParser());
// ...
// Here is my test route:
app.post('/test', function(req, res){
console.log('Mime type is:'+req.header('content-type'));
console.log('Raw data is:'+req.rawData);
console.log('Body via bodyParser is:');
console.dir(req.body);
res.send('Hello!');
})
I've tested it via curl:
$ curl -d 'test=hello' 127.0.0.1:3000/test
// console result:
Mime type is:application/x-www-form-urlencoded
Raw data is:
Body via bodyParser is:
{ test: 'hello' }
and:
$ curl -d 'test=hello' -H 'Content-Type:text/plain' 127.0.0.1:3000/test
// console result:
Mime type is:text/plain
Raw data is:test=hello
Body via bodyParser is:
{}
It's not actually integrate your middle ware to bodyParser, just make them work together.
