Confusion in Angular 2 Http Post Request

Question

First of all. Please bear with my questions.

What I am doing is just performing an ajax request which will return a response data of string.

Here\'s my php

Answer 1

Actually Angular looks for a backend server to post the data, so Imagine in your post request is like below

this.http.post('./app/parsers/peenoise.php', '', options).then(val => console.log(val))

It will try to make the post request at the location imagine you are serving angular on localhost:4200

http://localhost:4200/app/parsers/peenoise.php

Now to answer your Questions :

1)./app/parsers/peenoise.php doesn't work because it's actually trying to find it from your backend service

2)You need to put header('Access-Control-Allow-Origin: *') whenever you are making an http request to a different server than from the one which your site is currently using, if you don't use that you'll end up with Connection_refused_Error.

3)If you want to use just angular then there are mockAckends, in-memory-web-api

An example using mockBackEnd is here
