Question

我正在为Laravel应用程序制作安装脚本，我正在尝试创建管理员帐户作为安装步骤之一。出现错误时，应用程序应重定向回带有警报消息的同一页面，但Laravel会显示错误消息并停止应用程序：

public function postAdmin() {

$validation_rules = array(
    'username' => 'required|min:4|alpha_dash|unique:users',
    'email' => 'required|email|unique:users',
    'password' => 'required|min:4',
    );

$validator = Validator::make(Input::all(), $validation_rules);

if ($validator->fails()) {
    return Redirect::to('install/admin')
    ->withInput()
    ->withErrors($validator);
}

else {

    try {
     $username = Input::get('username');
     $email = Input::get('email');
     $password = Hash::make(Input::get('password'));

     $admin_user = new User;
     $admin_user->username = $username;
     $admin_user->email = $email;
     $admin_user->password = $password;
     $admin_user->admin = 1;

     $user_data_saved = $admin_user->save();

     if ($user_data_saved) {
        Auth::attempt(array('email' => Input::get('email'), 'password' => Input::get('password')));
        return Redirect::to('install/finish')->with('success', "Admin account created");
    } 
    else {
        return Redirect::to('install/admin')
        ->with('error', 'Error adding admin info');
    }
}
catch(Exception $e) {
    return Redirect::to('install/admin')->with('error', "Error creating admin account");
}

} }

是否可以使用try / catch检查错误并在出现错误时重定向以及如何进行？

Laravel捕获了一些错误，因此为了能够自己处理它们，您需要编辑app/Exceptions/Handler.php，并且可能使用render方法来处理自己的异常：

public function render($request, Exception $e)
{
    if ($result = MyExceptionHandler::handle($e))
    {
        return $result;
    }

    return parent::render($request, $e);
}

捕获异常和重定向
