{"count":1,"totalcount":38,"node":[{"categories":[],"foreignsource":null,"foreignid":null,"label":"172.20.96.20","assetrecord":{"description":null,"operatingsystem":null,"category":"unspecified","password":null,"id":2655,"username":null,"vmwaremanagedentitytype":null,"vmwaremanagementserver":null,"numpowersupplies":null,"hdd6":null,"hdd5":null,"hdd4":null,"hdd3":null,"hdd2":null,"hdd1":null,"storagectrl":null,"thresholdcategory":null,"enable":null,"connection":null,"autoenable":null,"cpu":null,"ram":null,"snmpcommunity":null,"rackunitheight":null,"admin":null,"additionalhardware":null,"inputpower":null,"vmwaremanagedobjectid":null,"vmwarestate":null,"vmwaretopologyinfo":null,"circuitid":null,"assetnumber":null,"rack":null,"slot":null,"region":null,"division":null,"department":null,"building":null,"floor":null,"room":null,"vendorphone":null,"manufacturer":null,"vendor":null,"modelnumber":null,"supportphone":null,"maintcontract":null,"maintcontractnumber":null,"maintcontractexpiration":null,"displaycategory":null,"notifycategory":null,"pollercategory":null,"vendorfax":null,"vendorassetnumber":null,"lastmodifiedby":"","lastmodifieddate":1433277477504,"dateinstalled":null,"lease":null,"leaseexpires":null,"managedobjectinstance":null,"managedobjecttype":null,"serialnumber":null,"port":null,"comment":null},"lastcapsdpoll":1433277477793,"createtime":1433277477504,"labelsource":"a","type":"a","id":"10"}]} my code:
var bodyparser = require('body-parser'); var urlencodedparser = bodyparser.urlencoded({ extended: true }); app.use('/index', function(req, res, next){ var getreq = http.request(options, function(res) { res.setencoding('utf8'); res.on('data', function (chunk) { jsnarry += chunk; }); res.on('end', function (chunk) { req.body = jsnarry; (var ndx in req.body){ console.log(req.body[ndx]); } next(); }); }).end(); }); app.use(bodyparser.json({ type: 'application/*+json' })); app.use('/index', urlencodedparser, function(req, res, next){ res.send(req.body); next(); }); console.log(json.parse(req.body)) o/p below ones
{ count: 1, totalcount: 38, node: [ { categories: [], foreignsource: null, foreignid: null, label: '172.20.96.20', assetrecord: [object], lastcapsdpoll: 1433277477793, createtime: 1433277477504, labelsource: 'a', type: 'a', id: '10' } ] } var options = { host: host, method: 'get', headers: { 'accept' : 'application/json' } }; res.json(info["totalcount"]); res.sendfile(path.join(_dirname, '/html', 'index.html')); //only shows res.json value not html page
below html file:
<!doctype html> <html data-ng-app="shopstore"> <head> <meta charset="iso-8859-1"> <title>simple angular testing</title> <link rel="stylesheet" type="text/css" href="css/bootstrap.min.css"></link> <link rel="stylesheet" type="text/css" href="css/main.css"></link> </head> <body> <script type="text/javascript" src="js/lib/angular.min.js"></script> <script type="text/javascript" src="js/lib/d3.min.js"></script> <script type="text/javascript" src="js/product.js"></script> <script type="text/javascript" src="js/app.js"></script> <div data-ng-controller="scopectrl"> <div data-ng-repeat="x in newrec"> <p>i product seller {{x.name}} in {{x.city}} @ {{x.country}}</p> </div> {{newrec[0].name}} </div> <div data-ng-controller="nmsctrl"> <p>data display</p> <!-- <div data-ng-repeat="jsn in jsndata"> <p>i product seller {{jsn.count}} displayed out of {{jsn.totalcount}}</p> </div> --> </div> <div data-ng-controller="store-controller store"> <div data-ng-repeat="product in store.products"> <div data-ng-hide='product.cantpur'> <h6>product:::{{product.item}}</h6> <h6>dollar price:::{{product.dollar | currency}}</h6> <h6>description::::{{product.desc}}</h6> <h6>{{review.stars}}</h6> <button data-ng-show='product.canadd'>add cart</button> <product-panel></product-panel> </div> </div> </div> </body> </html>
do include body-parsing middleware? body-parser support json parsing.
var app = require('express')(); var bodyparser = require('body-parser'); app.use(bodyparser.json()); bodyparser.json expect receive payload in application/json content type. example using jquery ajax:
.ajax({ url:url, type:"post", data:data, contenttype:"application/json; charset=utf-8", datatype:"json", success: function(){ ... } })
