title: Django - How to setup and test facebook login before going to production?
body: <p>So I am trying to add Facebook Login to my page but I am having some difficulties. I am trying to figure out how to test these features in development before I go to production but I don't completely understand how to do that.</p>
  
  <p>I have followed the facebook api instructions so I think I have something that should work but I can't test. That code is below:</p>
  
  <pre><code>&lt;script&gt;
    function fb_login() {
      FB.login( function() {}, { scope: 'email,public_profile' } );
    }
  
    // This is called with the results from from FB.getLoginStatus().
    function statusChangeCallback(response) {
      console.log('statusChangeCallback');
      console.log(response);
      // The response object is returned with a status field that lets the
      // app know the current login status of the person.
      // Full docs on the response object can be found in the documentation
      // for FB.getLoginStatus().
      if (response.status === 'connected') {
        // Logged into your app and Facebook.
        testAPI();
      } else if (response.status === 'not_authorized') {
        // The person is logged into Facebook, but not your app.
        document.getElementById('status').innerHTML = 'Please log ' +
          'into this app.';
      } else {
        // The person is not logged into Facebook, so we're not sure if
        // they are logged into this app or not.
        document.getElementById('status').innerHTML = 'Please log ' +
          'into Facebook.';
      }
    }
  
    // This function is called when someone finishes with the Login
    // Button.  See the onlogin handler attached to it in the sample
    // code below.
    function checkLoginState() {
      FB.getLoginStatus(function(response) {
        statusChangeCallback(response);
      });
    }
  
    window.fbAsyncInit = function() {
    FB.init({
      appId      : '************',
      cookie     : true,  // enable cookies to allow the server to access
                          // the session
      xfbml      : true,  // parse social plugins on this page
      version    : 'v2.2' // use version 2.2
    });
  
    // Now that we've initialized the JavaScript SDK, we call
    // FB.getLoginStatus().  This function gets the state of the
    // person visiting this page and can return one of three states to
    // the callback you provide.  They can be:
    //
    // 1. Logged into your app ('connected')
    // 2. Logged into Facebook, but not your app ('not_authorized')
    // 3. Not logged into Facebook and can't tell if they are logged into
    //    your app or not.
    //
    // These three cases are handled in the callback function.
  
    FB.getLoginStatus(function(response) {
      statusChangeCallback(response);
    });
  
    };
  
    // Load the SDK asynchronously
    (function(d, s, id) {
      var js, fjs = d.getElementsByTagName(s)[0];
      if (d.getElementById(id)) return;
      js = d.createElement(s); js.id = id;
      js.src = "//connect.facebook.net/en_US/sdk.js";
      fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));
  
    // Here we run a very simple test of the Graph API after login is
    // successful.  See statusChangeCallback() for when this call is made.
    function testAPI() {
      console.log('Welcome!  Fetching your information.... ');
      FB.api('/me', function(response) {
        console.log('Successful login for: ' + response.name);
        document.getElementById('status').innerHTML =
          'Thanks for logging in, ' + response.name + '!';
      });
    }
    &lt;/script&gt;
  </code></pre>
  
  <p>My App ID is correct in my application. </p>
  
  <p>Here is my login button:</p>
  
  <pre><code>&lt;a href="#" onclick="fb_login();"&gt;&lt;img src="../../static/textchange/facebookloginbutton.png" border="0" alt="" height="42px;"&gt;&lt;/a&gt;
          &lt;/div&gt;
  </code></pre>
  
  <p>I made my own so I could choose another image.</p>
  
  <p>So now when I try to login I get this error:</p>
  
  <p>"Given URL is not allowed by the Application configuration: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains."</p>
  
  <p>So I believe I have to choose another domain of some sort to test it? But I don't understand what I am supposed to choose? Do I have to start "hosting" so I can use a real domain? Can I do it locally?</p>
  
  <p>I would appreciate any help in pushing me in the right direction.</p>
  
  <p>Thanks.</p>
