Symfony2从URL检索参数值

Question

when i try to get the parameter from url its returning nothing

Here is my url : http://localhost/myapp/web/dailydata/payment/amount/1000

Here is my symfony script :

use Symfony\Component\HttpFoundation\Request;
.
.
public function MyAction()
{
    $request = $this->getRequest();
    $amount = $request->request->get('amount');
    echo 'Amount ='.$amount;
    exit;
}

Answer 1

You need to define a proper route in you routing.yml file like this:

my_action:
    path:      /dailydata/payment/amount/{amount}
    defaults:  { _controller: <bundle>:<controller>:My }

If you don't specify which part of the route is a parameter you can't access it from the action. Replace the various gaps (proper URL, bundle and controller) where necessary.

Answer 2

use Symfony\Component\HttpFoundation\Request;
.
.
public function MyAction()
{
    $request = $this->getRequest();
    $amount =$request->attributes->get('amount'); //replace this line in above code
    echo 'Amount ='.$amount;
    exit;
}
