$ http帖子被取消了

Question

我有一个登录表单，我试图向服务器发送一个帖子请求，但它被取消了。

这是控制器：

angular.module('app.signin', [])
.controller('SigninController', ['$http', function($http) 
{
    this.email      = null;
    this.password   = null;

    this.signIn = function()
    {
        var res = $http.post( 'http://api.svcassist.dev/index.php/auth/login', {email: this.email, password: this.password });

        res.success(function(data, status, headers, config) 
        {
                alert(data);
        });
    };
}]);

这里是html：

<div class="container" style="max-width:300px" ng-controller="SigninController as signin">
    <form class="form-signin">
        <h2 class="form-signin-heading">Sign In</h2>
        <label for="inputEmail" class="sr-only">Email address</label>
        <input type="email" id="inputEmail" name="email" class="form-control" placeholder="Email address" required autofocus ng-model="signin.email">
        <label for="inputPassword" class="sr-only">Password</label>
        <input type="password" id="inputPassword" name="password" class="form-control" placeholder="Password" required ng-model="signin.password">
        <br/>
        <button class="btn btn-lg btn-primary btn-block" ng-click="signin.signIn()">Sign In</button>
    </form>
</div> 

并且Chrome表示请求已取消，以下是响应标题：

我建议使用ng-submit：

HTML

<div class="container" style="max-width:300px" ng-controller="SigninController as signin">
    <form ng-submit="signin.signIn(signin.email, signin.email)" class="form-signin">
        <h2 class="form-signin-heading">Sign In</h2>
        <label for="inputEmail" class="sr-only">Email address</label>
        <input type="email" id="inputEmail" name="email" class="form-control" placeholder="Email address" required autofocus ng-model="signin.email">
        <label for="inputPassword" class="sr-only">Password</label>
        <input type="password" id="inputPassword" name="password" class="form-control" placeholder="Password" required ng-model="signin.password">
        <br/>
        <button class="btn btn-lg btn-primary btn-block" type="submit">Sign In</button>
    </form>
</div> 

JS

this.signIn = function(email, password)
{
    var res = $http.post( 'http://api.svcassist.dev/index.php/auth/login', {email: email, password: password });

    res.success(function(data, status, headers, config) 
    {
            alert(data);
    });
};
