Illuminate\Http\Request::get() should not be called statically

Illuminate\Http\Request::get() should not be called statically

其实不只是get方法，all()等方法都不能被静态调用

原因如下：

all());
}
```

4、和第三种方法用法一样，不过是直接写在构造方法里面的

```
use Illuminate\Http\Request;

class YourController extends Controller
{
protected $request;

public function __construct(Request $request)
{
$this->request = $request;
}

public function sign_up_user(Request $request){
dd($this->request->all());
}
}
```
