laravel 6 报错Symfony\Component\HttpFoundation\Request::isMethod() should not be called statically

laravel 6 使用Request 时报错Request::isMethod() should not be called statically

ErrorException
Non-static method Symfony\Component\HttpFoundation\Request::isMethod() should not be called statically

找到的英文提示是：The error message is due to the call not going through the Request facade。

解决办法是将：

use Illuminate\Http\Request;

改成：

use Request;
