node.js - How to make post request from angular to node server -


when print contents of request on node server, can't see user data anywhere.

here node server:

var http = require('http'); http.createserver( function (request, response) {       console.log(request); }).listen(8080); console.log('server running @ http://127.0.0.1:8080/');

and here angular2 code:

import { component, oninit } '@angular/core'; import { httpclient } "@angular/common/http"; import { http, response, headers , requestoptions } "@angular/http"; import 'rxjs/add/operator/retry'; // able retry when error occurs import { observable } "rxjs/rx";  @component({   selector: 'app-root',   templateurl: './app.component.html',   styleurls: ['./app.component.css'] })  export class appcomponent implements oninit{   title = 'angular test';   user = { id : 1, name : "hello"};   constructor (private http: http) {}    ngoninit(): void {     let headers = new headers({ 'content-type': 'application/json' });     let options = new requestoptions({ headers: headers });      console.log(this.user);      this.http.post("http://localhost:8080/", this.user, options)     .subscribe(      (err) => {         if(err) console.log(err);         console.log("success");      });   } }

can me out or explain how handle http request in angular.

that server:

const express = require('express') const bodyparser = require('body-parser'); const app = express()  app.use(bodyparser.json()); app.use(bodyparser.urlencoded({extended: true}) );  app.all("/*", function(req, res, next){   res.header('access-control-allow-origin', '*');   res.header('access-control-allow-methods', 'get,put,post,delete,options');   res.header('access-control-allow-headers', 'content-type, authorization, content-length, x-requested-with');   next(); });  app.post('/ping', function (req, res) {   res.send(req.body) })  app.listen(3000, function () {   console.log('example app listening on port 3000!') })

that angular client:

import { component } '@angular/core'; import { httpclient, httpheaders } '@angular/common/http';  @component({   selector: 'app-root',   templateurl: './app.component.html',   styleurls: ['./app.component.css'] }) export class appcomponent {   user = { id : 1, name : 'hello'};    constructor(private http: httpclient) { }    callserver() {     const headers = new httpheaders()           .set('authorization', 'my-auth-token')           .set('content-type', 'application/json');      this.http.post('http://127.0.0.1:3000/ping', json.stringify(this.user), {       headers: headers     })     .subscribe(data => {       console.log(data);     });   } }

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
