Laravel的Hash缺少论点？

I'm getting a weird error in Laravel 5.3's hash mechanism.

Missing argument 2 for Illuminate\Hashing\BcryptHasher::check(), called in C:\xampp\htdocs\Missionseek2\vendor\laravel\framework\src\Illuminate\Support\Facades\Facade.php on line 237 and defined

This is the code that defines it.

public function postSignIn(Request $request){

        $val = DB::table('ministry')->where('Username', Input::get('Username'))->first();

        if ($val && Hash::check(Input::get('Password', $val->Password))) {
            return redirect()->route('agencydash');
        } return 'failed';
       // if (Auth::attempt(['Username' => $request['Username'], 'Password' => $request['Password']])) {
       //     return redirect()->route('agencydash');
       // }
        //return redirect()->back();
    }

What's going on here? I feel like it's not getting the password value from the database and so we're getting an error, but I'm not sure why. The name's are correct.

You are passing 2 argument in Input::get() instead of check(). You have to correct brackets positions

if ($val && Hash::check(Input::get('Password'), $val->Password))

I think your parenthesis is not in the right place

You have :

Hash::check(Input::get('Password', $val->Password))

And I think you have to move your parenthesis to :

Hash::check(Input::get('Password'), $val->Password)

Not sure how Hash::check works, but here

Hash::check(Input::get('Password', $val->Password))

you gave it only one parameter.

I think you have something wrong in your parentheses.

if ($val && Hash::check(Input::get('Password', $val->Password)))

becomes

if ($val && Hash::check(Input::get('Password'), $val->Password))
