我怎样才能让 UID RFID 到 Laravel 的文本字段

如何解决我怎样才能让 UID RFID 到 Laravel 的文本字段

所以我有一个带有 RFID 的项目 laravel。当我想发布数据时,它需要 UID 形式的 RFID 阅读器。但错误看起来像在服务器上找不到 URL?我怎样才能解决这个问题?有人可以帮我吗?

这是我的 Laravel ManjmhsController

public function create()
    {
        return view('addmhs');
    }

public function store(Request $request)
    {
        $request->validate([
            'uid'           => 'required','nim'           => 'required|unique:mahasiswa','nama_mhs'      => 'required','foto'          => 'mimes:jpg,jpeg,png,gif,svg,JPG,PNG,JPEG','tempat_lahir'  => 'required','tgl_lahir'     => 'required','kelas'         => 'required','jurusan'       => 'required','alamat'        => 'required','email'         => 'required|max:50|string|email|max:255','no_telfon'     => 'required','saldo'         => 'required' 
        ]);

        if ($request->hasFile('foto')) {
            $foto = $request->file('foto');
            $ext = $foto->getClientOriginalExtension();
            $fotoName = $request->nama_mhs . date('YmdHis') . '.' . $ext;
            $path = public_path('img/');
            $foto->move($path,$fotoName);
        } else {
            $fotoName = 'default.png';
        }
        
        $only = $request->only('uid','nim','nama_mhs','tempat_lahir','tgl_lahir','kelas','jurusan','alamat','email','no_telfon','saldo');
        $dataFoto = [
            'foto' => $fotoName
        ];
        $data = array_merge($only,$dataFoto);
        Mahasiswa::create($data);

        return redirect('manjmhs');

    }

这是我的arduino脚本

    byte nib1 = (array[i] >> 4) & 0x0F;
    byte nib2 = (array[i] >> 0) & 0x0F;
    buffer[i * 2 + 0] = nib1  < 0xA ? '0' + nib1  : 'A' + nib1  - 0xA;
    buffer[i * 2 + 1] = nib2  < 0xA ? '0' + nib2  : 'A' + nib2  - 0xA;
  }
  buffer[len * 2] = '\0';
}

这是我的错误看起来像 error monitor

谁能帮帮我?谢谢
