I've looked everywhere I can to find a solution to this. The only thing I've found is an unanswered post. I apologize if I've overlooked something.
The problem is that when I try to get the POST
values in the /createQuestion
API, the body is empty/undefined. I get errors like this Cannot read proprety 'question' of undefined
coming from the API.
The Express API:
app.post("/createQuestion", function(req, res) {
var questionType = req.body.question.type;
var questionText = req.body.question.text;
var questionDuringClass = req.body.question.duringClass;
// Do a bunch of stuff
res.send(response);
});
The test:
var should = require('should');
var assert = require('assert');
var request = require('supertest');
var winston = require('winston');
request = request('http://localhost:8080');
describe('Questions', function() { // Test suite
before(function(done) {
done();
});
it('Should create a freeResponse question', function(done) { // Test case
var postData = {
"question" : {
"type" : "freeResponse",
"text" : "This is a test freeResponse question (automated testing)",
"duringClass" : "1"
}
};
request()
.post('/createQuestion')
.send(postData)
.expect(200)
.end(function(err, res) { // .end handles the response
if (err) {
return done(err);
}
done();
});
});
it('Should delete a freeResponse question', function(done) { // Test case
var postData = {
"question" : {
"type" : "freeResponse",
"text" : "This is a test freeResponse question (automated testing)",
"duringClass" : "1"
}
};
request()
.post('/deleteQuestion')
.send(postData)
.expect(200)
.end(function(err, res) { // .end handles the response
if (err) {
return done(err);
}
done();
});
});
What am I missing? Is the .send()
sending the POST
data in some different format? Is it not POST
ing it to the body of the request?
It's probably that your app is not using bodyParser middleware in place.
app.use(express.bodyParser());
From the expressjs docs:
req.body
This property is an object containing the parsed request body. This feature is provided by the bodyParser() middleware, though other body parsing middleware may follow this convention as well. This property defaults to {} when bodyParser() is used.
Here you have a complete example
var express = require('express');
var request = require('supertest');
var assert = require('assert');
var app = express();
app.use(express.bodyParser());
app.get('/', function(req, res) {
res.send('ok');
});
app.post('/createQuestion', function(req, res) {
var message = req.body.partA + ' ' + req.body.partB;
res.send(message);
});
describe('testing a simple application', function() {
it('should return code 200', function(done) {
request(app)
.get('/')
.expect(200)
.end(function(err, res){
if(err) {
done(err);
} else {
done();
}
});
});
it('should return the same sent params concatenated', function(done) {
request(app)
.post('/createQuestion')
.send({ partA: 'Hello', partB: 'World'})
.expect(200, 'Hello World')
.end(function(err, res){
if(err) {
done(err);
} else {
done();
}
});
});
});
