我想调用函数$ request-> ip()一次并将ip放在一个常量中,以便每次都不需要调用该函数。因此,由于未在页面中调用函数10次,资源使用量会减少,而只能回显从该函数中提取的已定义常量一次。
Laravel有可能吗?如果是的话怎么样?

您可以使用Sessions
覆盖login()
中的LoginController
方法并添加以下内容:
if(!\Session::has('user_ip'))
\Session::put('user_ip',$request->ip());
完整方法:
/**
* Handle a login request to the application.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function login(Request $request)
{
$this->validateLogin($request);
// If the class is using the ThrottlesLogins trait, we can automatically throttle
// the login attempts for this application. We'll key this by the username and
// the IP address of the client making these requests into this application.
if ($this->hasTooManyLoginAttempts($request)) {
$this->fireLockoutEvent($request);
return $this->sendLockoutResponse($request);
}
if ($this->attemptLogin($request)) {
if(!\Session::has('user_ip'))
\Session::put('user_ip',$request->ip());
return $this->sendLoginResponse($request);
}
// If the login attempt was unsuccessful we will increment the number of attempts
// to login and redirect the user back to the login form. Of course, when this
// user surpasses their maximum number of attempts they will get locked out.
$this->incrementLoginAttempts($request);
return $this->sendFailedLoginResponse($request);
}
请记住导入\ Illuminate \ Http \ Request:
use Illuminate\Http\Request;
现在你可以在任何地方使用Session::get('user_ip')

我不相信呼叫$request->ip()
比调用会话甚至常量更多地使用资源。
使用$_SERVER
超全局的任何php请求始终可以访问IP,$request->ip()
只是一个包装器。
