php - API rest codeigniter POST 方法返回 null

Question

我正在RESTFUL为 codeigniter 使用 Phil Sturgeons 库。但我对 POST 方法有疑问。

$this->post('name');

当我尝试捕获该值时，上面的代码总是返回 null。

这是我的要求: Request Url: http://localhost/api_rest/login Request Method: POST Status Code: 400 Params: { "email": "example@email.com", "password": "balbala" }:

function login_post()
{ 
if(!$this->post('email') || !$this->post('password')){
        $this->response(array('error' => 'Email and Password leave blank'),400);
    } 

是的，它的返回状态码：400 because $this->post('email') or $this->post('password')绝对返回false。

也许你应该知道我的错误：

<p>Message:  simplexml_load_string(): ^</p>

</div>{"error":"Email and Password leave blank"}

有人对这个东西有想法吗？

Answer 1

添加

} 别的 {

$this->response(_$SERVER); }

或者

} 其他 { $this->response(_$POST); }

查看发送到该方法的内容。

Answer 2

这样做

     $postdata = file_get_contents("php://input");
      header('Content-type: application/json');
      $obj = json_decode($postdata,true);
      $email=$obj['email'];
      $password=$obj['password'];
      then do the rest
