Alamofire 请求参数为空

Question

我正在尝试使用 Alarmofire 库发送 POST 请求，但该请求未正确发送参数。

我的代码：

let parameters : Parameters = [
    "email": tfLoginEmail.text! as String,
    "password": tfLoginPassword.text! as String
]
Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default).responseJSON{ response in
    //Some code that uses the response
}

参数变量的计数为 2 并且两个值都存在，但对该请求的响应是关于电子邮件和/或密码为空的错误。

编辑： 我的PHP：

/**
 * Account Login
 * url - /login
 * method - POST
 * params - email, password
 */
$app->post('/login', function() use ($app) {
            // check for required params
            verifyRequiredParams(array('email', 'password'));

            // reading post params
            $email = $app->request()->post('email');
            $password = $app->request()->post('password');
            $response = array();

            $db = new DbHandler();
            // check for correct email and password
            if ($db->checkLogin($email, $password)) {
                // get the user by email
                $account = $db->getAccountByEmail($email);

                if ($account != NULL) {
                    $response["error"] = false;
                    $response['id'] = $account['id'];
                    $response['name'] = $account['name'];
                    $response['email'] = $account['email'];
                } else {
                    // unknown error occurred
                    $response['error'] = true;
                    $response['message'] = "An error occurred. Please try again";
                }
            } else {
                // user credentials are wrong
                $response['error'] = true;
                $response['message'] = 'Login failed. Incorrect credentials';
            }
            echoRespnse(200, $response);
        }); 

我想知道我做错了什么。 提前致谢。

显然，服务器希望请求正文是 URL 编码的字符串，而不是 JSON。使用encoding: URLEncoding.httpBody 而不是encoding: JSONEncoding.default 来解决此问题。
