AngularJS $http.post 请求被 Chrome 取消

Question

我已经用谷歌搜索了几个小时...

这是我的 angularJS 代码:

var FrontControllers = angular.module('FrontControllers', [] );

FrontControllers.controller('LoginController', ['$scope', '$http', function($scope, $http){

    $scope.user = {};

    $scope.login = function() {
        console.log($scope.user);
        $http({
            url: '/webapi/login',
            method: 'POST',
            data: $scope.user
        }).success(function (data) {
            alert("success!");
        }).error(function(data) {
            alert("failed =(");
        });

    };
}]);

这是随附的 html

<div ng-controller="LoginController" id="login" class="box">

    <form novalidate role="form" action="/webapi/login" id="loginForm">                   
        <label for="signin" class="sr-only">Email or Username</label> 
        <input ng-model="user.username" type="text" autofocus class="form-control input-lg" id="username" name="username" size="20" placeholder="email or username">

        <label for="password" class="sr-only">Password</label> 
        <input ng-model="user.password" type="password" class="form-control input-lg" id="password" name="password" size="10" placeholder="password">

       <button ng-click="login()" type="submit" class="btn btn-lg btn-bright btn-block">Login</button>
    </form>

</div>

无论我做什么，我最终都会收到一个被取消的 POST 请求。我以前使用标准 jQuery ajax 代码成功登录到/webapi/login。服务器针对 AJAX 配置，因此不需要 urlencode header 。 Payload 看起来是正确的，与 jQuery ajax 发送的相同。

可能是什么问题？

Angular 不会preventDefault()如果action参数已设置。参见 here

For this reason, Angular prevents the default action (form submission to the server) unless the element has an action attribute specified.

您可能还应该使用 ng-submit="login()在 <form> 上而不是 ng-click , 以便在用户按下 Enter 时提交表单
