javascript - AngularJS Error: Cross origin requests are only supported for protocol schemes: http, data, chrome-extension, https

I have three files of a very simple angular js application

index.html

<!DOCTYPE html>
<html ng-app="gemStore">
  <head>
    <script src='.3.8/angular.min.js'></script>
    <script type="text/javascript" src="app.js"></script>
  </head>

  <body ng-controller="StoreController as store">
      <div class="list-group-item" ng-repeat="product in store.products">
        <h3>{{product.name}} <em class="pull-right">{{product.price | currency}}</em></h3>
      </div>

  <product-color></product-color>
  </body>
</html>

product-color.html

<div class="list-group-item">
    <h3>Hello <em class="pull-right">Brother</em></h3>
</div>

app.js

(function() {
  var app = angular.module('gemStore', []);

  app.controller('StoreController', function($http){
              this.products = gem;
          }
  );

  app.directive('productColor', function() {
      return {
          restrict: 'E', //Element Directive
          templateUrl: 'product-color.html'
      };
   }
  );

  var gem = [
              {
                  name: "Shirt",
                  price: 23.11,
                  color: "Blue"
              },
              {
                  name: "Jeans",
                  price: 5.09,
                  color: "Red"
              }
  ];

})();

I started getting this error as soon as I entered an include of product-color.html using custom directive named productColor:

XMLHttpRequest cannot load file:///C:/product-color.html. Cross origin requests are only supported for protocol schemes: http, data, chrome-extension, https, chrome-extension-resource.
angular.js:11594 Error: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'file:///C:/product-color.html'.

What may be going wrong? Is it a path issue for product-color.html?

All my three files are in the same root folder C:/user/project/

1 Just a quick pointer that if you do something stupid, such as in my case I accidentally appended the TLD to the port: "localhost:8070.com" then you will receive the same error. Check what URL you're attempting to resolve! – Wildhoney Commented Jul 31, 2015 at 14:25

Sorted by: Reset to default 308

This error is happening because you are just opening html documents directly from the browser. To fix this you will need to serve your code from a webserver and access it on localhost. If you have Apache setup, use it to serve your files. Some IDE's have built in web servers, like JetBrains IDE's, Eclipse...

If you have Node.Js setup then you can use http-server. Just run npm install http-server -g and you will be able to use it in terminal like http-server C:\location\to\app.

VERY SIMPLE FIX

Go to your app directory
Start SimpleHTTPServer

In the terminal

$ cd yourAngularApp
~/yourAngularApp $ python -m SimpleHTTPServer

Now, go to localhost:8000 in your browser and the page will show

The operation is not allowed in chrome. You can either use a HTTP server(Tomcat) or you use Firefox instead.

My problem was resolved just by adding http:// to my url address. for example I used http://localhost:3000/movies instead of localhost:3000/movies.

If you are using this in chrome/chromium browser(ex: in Ubuntu 14.04), You can use one of the below command to tackle this issue.

ThinkPad-T430:~$ google-chrome --allow-file-access-from-files
ThinkPad-T430:~$ google-chrome --allow-file-access-from-files fileName.html

ThinkPad-T430:~$ chromium-browser --allow-file-access-from-files
ThinkPad-T430:~$ chromium-browser --allow-file-access-from-files fileName.html

This will allow you to load the file in chrome or chromium. If you have to do the same operation for windows you can add this switch in properties of the chrome shortcut or run it from cmd with the flag. This operation is not allowed in Chrome, Opera, Internet Explorer by default. By default it works only in firefox and safari. Hence using this command will help you.

Alternately you can also host it on any web server (Example:Tomcat-java,NodeJS-JS,Tornado-Python, etc) based on what language you are comfortable with. This will work from any browser.

If for whatever reason you cannot have the files hosted from a webserver and still need some sort of way of loading partials, you can resort to using the ngTemplate directive.

This way, you can include your markup inside script tags in your index.html file and not have to include the markup as part of the actual directive.

Add this to your index.html

<script type='text/ng-template' id='tpl-productColour'>
 <div class="list-group-item">
    <h3>Hello <em class="pull-right">Brother</em></h3>
</div>
</script>

Then, in your directive:

app.directive('productColor', function() {
      return {
          restrict: 'E', //Element Directive
          //template: 'tpl-productColour'
          templateUrl: 'tpl-productColour'
      };
   }
  );

RootCause:

File protocol does not support cross origin request for Chrome

Solution 1:

use http protocol instead of file, meaning: set up a http server, such as apache, or nodejs+http-server

Sotution 2:

Add --allow-file-access-from-files after Chrome`s shortcut target, and open new browse instance using this shortcut

Solution 3:

use Firefox instead

Install the http-server, running command npm install http-server -g
Open the terminal in the path where is located the index.html
Run command http-server . -o
Enjoy it!

I would add that one can also use xampp, mamp type of things and put your project in the htdocs folder so it is accessible on localhost

If you are running server already, don't forget to use http:// in the API call. This might cause a serious trouble.

The Reason

You are not opening the page through a server, like Apache, so when the browser tries to obtain the resource it thinks it is from a separate domain, which is not allowed. Though some browsers do allow it.

The Solution

Run inetmgr and host your page locally and browse as http://localhost:portnumber/PageName.html or through a web server like Apache, nginx, node etc.

Alternatively use a different browser No error was shown when directly opening the page using Firefox and Safari. It comes only for Chrome and IE(xx).

If you are using code editors like Brackets, Sublime or Notepad++, those apps handle this error automatically.

This issue is not happening in Firefox and Safari. Make sure you are using the latest version of xml2json.js. Because i faced the XML parser error in IE. In Chrome best way you should open it in server like Apache or XAMPP.

there is a chrome extension 200ok its a web server for chrome just add that and select your folder

You have to open chrome using the following flag Go to run menu and type "chrome --disable-web-security --user-data-dir"

Make sure all the instances of chrome are closed before you use the flag to open chrome. You will get a security warning that indicates CORS is enabled.

Adding to @Kirill Fuchs excellent solution and answering @StackUser's doubt - while starting the http-server, set the path till the app folder only, NOT till the html page! http-server C:\location\to\app and access index.html under app folder

Navigate to C:/user/project/index.html, open it with Visual Studio 2017, File > View in Browser or press Ctrl+Shift+W

I had the same issue. after adding below code to my app.js file it fixed.

var cors = require('cors')
app.use(cors());
