use Illuminate\Http\Request;
use Excel;

class UserController extends Controller
{
    public function import(Request $request)
    {
        // 获取上传的Excel文件存放路径
        $file = $request->file('file')->getRealPath();
        
        // 使用laravel-excel组件读取Excel表格数据
        $data = Excel::load($file)->get()->toArray();
        
        // 将读取到的Excel表格数据导入到users表中
        foreach ($data as $value) {
            User::create($value);
        }
        
        // 导入完成返回成功响应
        return response()->json(['success' => true]);
