Yeoman, Grunt, AngularJS and error 404 on POST for

问题:

I am trying to send a form with "POST" method with AngularJS. I use $http to send it but it always return "Cannot POST" and 404 error. The route is correct and only happens if I execute my app via Grunt (sending by "GET" works perfect). The app has been built using Yeoman.

I think that it has to be a silly problem but I cannot make it work.

The view:

<form name="formLogin" ng-submit="login()">

<ul>
    <li>
        <label for="user">User</label>
        <input type="text" id="user" name="user" ng-model="user">
    </li>
    <li>
        <label for="pass">Password</label>
        <input type="password" id="pass" name="pass" ng-model="pass">
    </li>

</ul>

<input type="submit" value="Send">

The controller:

    'use strict';
angular.module('myApp')
  .controller('LoginCtrl', function ($scope, $http, $resource) {


    $scope.login = function() {

      var config = {
        url: 'php/login.php',
        method: 'POST',
        data: {
            user: $scope.user,
            pass: $scope.pass
        }
      }; // configuration object

      $http(config)
        .success(function(data, status, headers, config) {
            console.log('success');
            if (data.status) {
              // succefull login

            } else {
              // Wrong login
            }
        })
        .error(function(data, status, headers, config) {
            console.log('error');

        });

    };

  });

I use Grunt with:

grunt server

Why happens that?

Thanks!

I'm confused why GET should work in this case. The Grunt server just serves static files from your app and .tmp directories and your reference to the .php file is relative. So with the standard setup, an AJAX request to php/login.php would just return you the plain PHP source code of the file located in app/php/login.php, which is certainly not what you want.

You probably want to separate your backend from your frontend and have your PHP application in a different location. This could either be under a different location (e.g. /api/login.php) or a different host https://api.example.com/login.php. Mixing your Yeoman application with your API isn't a good idea.

However, if you are forced to keep them within one project, you can use grunt-php to start a local PHP server from your Gruntfile.

Angular by default sends http post requests as application/json and not as application/x-www-form-urlencoded which may cause problems. Change your application to accept application/json or replace application/json with application/x-www-form-urlencoded in $httpProvider.defaults.headers.post and serialize form yourself.
