Used this code. But it didin't gives the post values.

Answer 1

In your observer constructor do:

public function __construct(
    \Magento\Framework\App\RequestInterface $request
)
{
    $this->_request = $request;
}

Then in your code use $this->_request to fetch post params, like below :

$post = $this->_request->getPost();

Answer 2

$data = $this->getRequest()->getParams();
