Overview
The Symfony HttpFoundation Request Component provides methods for working with server requests. It supports manipulating the request parameters, setting headers, conducting redirects, and working with uploaded files.
The Request component also provides methods to get information about the current request, such as the requested URL, the request method, the client's IP address, the user agent, and more.
All request methods and properties are accessible on the $request object, which is provided by the component.
Example
Let's say we wanted to get the request method and the user agent of the request object. We can do this like this:
$method = $request->getMethod();
$userAgent = $request->getUserAgent();
Now, $method will contain the GET or POST of the request, and $userAgent will contain the user agent of the client.

$request->redirect('/');
Uploaded Files
The component includes methods for working with uploaded files. For example, if we wanted to get an uploaded file and move it to a specific folder, we can do it like this:
