Node Mongo REST Service Post

问题:

I have created a REST service using Node.js and MongoDB for using in one of my Android app. The get methods is working as expected when called from Android App. I am trying to build a JSON object from Android App with necessary details and post to the service.I am unable to post to my collections. Below is the code snippet I have used in my Node.js

app.post('/accounts/put/:uObject', function(req, res, next) {
  var username=uObject.name;

  db.collection('test').insert({"username":username},function(err,docs){if(err){
                res.send("There was some problem during insertions of linkes");
            }
           else{
                res.send("Fail");

           } });

});

What Am I doing wrong in this? I am getting the object as parameter and getting the values inside the function and passing to the insert.

To get the parameter from the route you need to use req.params, in your case req.params.uObject. Also common practice in JavaScript is to return early upon a condition being met.

app.post('/accounts/put/:uObject', function(req, res, next) {
    var username = req.params.uObject;

    db.collection('test').insert({
        "username": username
    }, function(err, docs) {
        if (err) {
            return res.send("There was some problem during insertions of linkes");
        }
        res.send("Fail");
    });

});
