Request.body is empty when issuing POST requests containing JSON body

I have been struggling for hours with this problem and I feel like I am stuck on this. I am doing the NodeJS, ExpressJS and MongoDB tutorial. I've built a simple API in ExpressJS.

When issuing a cURL POST request containing a JSON body, the req.body is empty and so I see an error.

Here are some sources / details:

CURL request:

curl -i http://localhost:3000/wines -X POST -H "Content-Type: application/json" -d "{'name': 'New Wine', 'year': '2009'}"

Route:

app.post('/wines', wines.addWine);

API method:

exports.addWine = function (req, res) {
console.log('Req body' + req.body);
var wine = req.body;
console.log('Adding wine: ' + JSON.stringify(wine));

db.collection('wines', function (err, collection) {
    collection.insert(wine, {safe:true}, function (err, result) {
        if (err) {
            res.send({'error':'An error has occurred'});
        } else {
            console.log('Success: ' + JSON.stringify(result[0]));
            res.send(result[0]);
        }
    });
});
}

The following error is thrown:

Listening on port 3000...
Connected to 'winedb' database
Req bodyundefined
Adding wine: undefined
TypeError: Cannot read property '_id' of undefined
    at insertAll (/home/ebsk/Documents/Dev/Node/nodecellar/node_modules/mongodb            /lib/mongodb/collection.js:291:39)
    at Collection.insert (/home/ebsk/Documents/Dev/Node/nodecellar/node_modules/mongodb    /lib/mongodb/collection.js:92:3)
    at exports.addWine (/home/ebsk/Documents/Dev/Node/nodecellar/routes/wines.js:56:20)

I am looking forward to hearing from you. Thanks in advance for any suggestions.

If you've ever had problems with the request body in express, the first thing you should check is that the app is configured to use bodyParser

, i.e .:

app.use(express.bodyParser());


In this particular case, you can check if your implementation matches.
