Request::getArgs() can't get data from STDIN

[Mongo]

Request::getArgs() can't get data from STDIN when client post JSON / XML to Server.
for example:
post JSON via angularjs

$http({
    url: '/api/task/create',
    method: "POST",
    data: JSON.stringify(newTask)
    }).success(function(data) {
            console.log(data);
    })
})

in Action:

$this->request->getArgs(); // got nothing

额，看源码的我是。

    public function getArg($name)
    {
        if (isset($_POST[$name])) {
            return $_POST[$name];
        } else if (isset($_GET[$name])) {
            return $_GET[$name];
        } else if (isset($this->_jsonParams[$name])) {
            return $this->_jsonParams[$name];
        }

        return false;
    }

看情况必须一个个单独取出来，你的getArgs()漏了参数name。
