在构造函数中添加

$this->load->library（'form_validation'）

因此，您的构造函数如下所示：

function __construct() {
    parent::__construct();
    $this->API="http://localhost/rest_ci/index.php";
    $this->load->helper('form');
    $this->load->helper('url');
    $this->load->library('session');
    $this->load->library('curl');
    $this->load->library('form_validation');
}

}

您在'id'=>$this->post（'id'）中缺少输入

因此，正确的代码如下所示：

'id' => $this->input->post('id')

您还必须在所有其他位置使用输入。
