Getting my head around node.js and have developed a simple service:
// set up ======================================================================
var express = require('express');
var app = express(); // create our app w/ express
var port = process.env.PORT || 8080; // set the port
var bodyParser = require('body-parser');
//var methodOverride = require('method-override')
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
app.use(function (req, res, next) {
//the code hits this point!
var data = '';
req.on('data', function (chunk) {
data += chunk;
});
req.on('end', function () {
req.rawBody = data;
next();
});
//console.log(data);
});
//app.use(methodOverride());
// routes ======================================================================
require('./routes.js')(app);
// listen (start app with node server.js) ======================================
app.listen(port);
console.log("App listening on port " + port);
routes.js
var _ = require('underscore');
module.exports = function (app) {
app.post('/', function (req, res) {
var Validator = require('jsonschema').Validator;
var v = new Validator();
var jso = req.rawBody;
var newjso = JSON.parse(req.rawBody);
var schema={
"description": "A payload",
"type": "object"
};
var result = v.validate(newjso,schema);
console.log('----------------------payload--------------------------------------')
console.log(newjso);
console.log('------------------end payload--------------------')
if (result.errors.length > 0) {
res.setHeader('content-type', 'application/json');
res.status(400);
res.json({
"error": "Could not decode request: JSON parsing failed"
});
console.log('------------------ERROR!!!--------------------')
}
else
{
var resp = _.filter(_.where(newjso.payload, {drm: true}), function (item) {
return item.episodeCount > 0
});
var newArray = [];
resp.forEach(function (item) {
var newItem = _.pick(item, 'image', 'slug', 'title');
newItem.image = _.propertyOf(newItem.image)('showImage');
newArray.push(newItem);
})
res.setHeader('content-type', 'application/json');
res.status(200);
res.json({response: newArray});
}
})
}
When I post this or any other json to postman:
{
"payload": [
{
}]
}
It looks like it is timing out when the Contenttypeheader = application/json is specified. Why is it timing out and how can I fix this in my node.js program?
It's because
bodyParser.json()
has already parsed the entirety of the request, soend
will never fire in your custom middleware. Again, I don't see why you are trying to capture the raw request when all you are doing is passing it toJSON.parse()
, which is whatbodyParser.json()
already does.
