PHP不接收从$ http.post发送的数据

Question

I have a function inside an AngularJS controller that let me send POST data to a PHP page (it should be for authentication)

$scope.submit = function () {
    $http.post(api + 'login.php', $scope.user)
};

This function is called from this HTML code

<div>
    <span ng-show="isAuthenticated">{{welcome}}</span>
    <form ng-show="!isAuthenticated" ng-submit="submit()">
        <input ng-model="user.username" type="text" name="user" placeholder="Username" />
        <input ng-model="user.password" type="password" name="pass" placeholder="Password" />
        <input type="submit" value="Login" />
    </form>
    <div>{{error}}</div>
    <div ng-show="isAuthenticated">
        <a ng-click="logout()" href="">Logout</a>
    </div>
</div>

Using Firebug inside Firefox I can see that auth page is called and POST data is sent correctly

Problem raises within my auth PHP code: I try to retrieve POST data, but array is empty.
I've also tried to write content in a file and I can confirm array is empty (file contains [])

$userdata = $_POST;
file_put_contents("login.txt",json_encode($userdata)."\n", FILE_APPEND);

What's wrong with my code? I've also tried changing from POST to GET (using $http.get ), but $_GET array is empty too...

Angular将数据作为json发送，而不是作为表单数据，以检索它，您可以执行以下操作：

$_JSON = json_decode(file_get_contents("php://input"), true);
