how can i send http post request from localhost:5000 to localhost:3000

Question

I'm trying to send a http post request from application running on localhost:5000 to my server at localhost:3000

this angular script is running on localhost:5000

    var data = {name:"john", description:"100"};
    var url = 'localhost:3000/razor';

    $http.post(url, data).then(function(response){
      if(response.data){
        console.log("success");
      } else {
        console.log("failure");
      }
    });

localhost:3000 is not receiving any POST request. What should I do? Error in console -

Error: A network error occurred.

Answer 1

Without http in front of the url, the url becomes relative to the current url which is ' http://localhost:5000 ', so the url that you're posting to becomes ' http://localhost:5000/localhost:3000/razor ', but when you add http in front of the url, it becomes absolute url.

Answer 2

You need to add http in front of url path to make it absolute URL Try replacing this once

var url = ' http://localhost:3000/razor ';
