has no method checkBody

I am using express 4.11.1 and express-validator 2.8.0.

here is the code i used above post action:

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

and inside post action i gave

req.checkBody(‘postparam’, ‘Invalid postparam’).notEmpty().isInt();

i am getting has no method checkBody error, don know whether version is the problem so mentioned the versions above.

Just a clarifying comment on this issue: make sure you “use” your routers after you have added expressValidator. (Which makes sense but I had too look for this for a while)

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

app.use(bodyParser.urlencoded());
app.use(expressValidator());

// Now we can start adding routers to our app
app.use('/example', exampleRouter);

Looks like you forgot to register the bodyParser and expressValidator middleware with the app (which will add the validation methods to the request object).

Try:

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

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))

// parse application/json
app.use(bodyParser.json())

// add validation methods to request
app.use(expressValidator());

// now the methods are available
app.post('/', function(req, res, next) {
    req.checkBody('postparam', 'Invalid postparam').notEmpty().isInt();
});
