POST request through a JSON object

I have created a server which serves the post request for a client. I am using the bodyserver, but getting some error

var bodyParser = require('body-parser')
     var express = require('express');
        var app = express();

app.use(bodyParser.json());

app.post('/v3/botstate/:channel/users/:userid', function (req, res) {
    console.log("hsijdaf");
    console.log(req.body);
    //console.log(req.body);        

 //  res.send('Hello POST');

})
var server = app.listen(8081, function () {

  var host = server.address().address
  var port = server.address().port

  console.log("Example app listening at http://%s:%s", host, port)

})

A client is as shown below,

var request = require('request');
request.post({
            url: "http://localhost:8081/v3/botstate/webchat/users/siddiq",
           headers: {
                "Content-Type": "application/json"
            },
            body: '{"jsonrpc":"2.0","id":"zdoLXrB5IkwQzwV2wBoj","method":"barrister-idl","params":[]}',
            json:true
}, function(error, response, body){
console.log(error);
console.log(JSON.stringify(response));
  console.log(body);
});

while running the client getting the below error, 

E:\TESTING>node exp.js
Example app listening at http://:::8081
SyntaxError: Unexpected token "
    at parse (E:\TESTING\node_modules\body-parser\lib\types\json.js:83:15)

    at nextTickCallbackWith2Args (node.js:442:9)
    at process._tickCallback (node.js:356:17)

You have set Content-Type : application/json in your client, but your POST data is text/plain, not json. That's why body-parser is failing to parse it as it was expecting json through header.

Try after removing ' ' from body in your client.

e.g.

var request = require('request');
request.post({
     url: "http://localhost:8081/v3/botstate/webchat/users/siddiq",
     headers: {
        "Content-Type": "application/json"
     },
     body: {
       "jsonrpc":"2.0",
       "id":"zdoLXrB5IkwQzwV2wBoj",
       "method":"barrister-idl",
       "params":[]
     },
     json:true
}, function(error, response, body){
   console.log(error);
   console.log(JSON.stringify(response));
   console.log(body);
});

Hope it helps you.
