散列密碼時，CakePHP 3中出現錯誤：hash（）至少需要2個參數，其中1個是給定的APP / Model / Entity / User.php

Question

我正在關注官方書簽器教程 ： http : //book.cakephp.org/3.0/en/quickstart.html#bookmarker-tutorial

但是在向我的User類添加_setPassword（$ value）方法后，我收到了這些警告，這些警告使我無法將哈希密碼正確保存在users表中。

Warning (2): hash() expects at least 2 parameters, 1 given [APP/Model/Entity/User.php, line 26]
Warning (4096): Object of class Cake\Auth\DefaultPasswordHasher could not be converted to string [APP/Model/Entity/User.php, line 26]
Notice (8): Undefined variable: _SESSION [CORE/src/Network/Session.php, line 440]

• 這是我在App \\ Model \\ Entity \\ User中的方法 ：

protected function _setPassword($value)
    {
        $hasher = new DefaultPasswordHasher();
        return $hasher.hash($value);
    }

• 我在數據庫中的密碼字段 的長度為255 （由於MySQL中字段的長度以及CakePHP 3使用的新加密方法，有人報告存在問題）。

• 我的PHP版本是PHP 5.5.20（cli）（建立於：2015年2月25日23:30:53）

• 在我的error.log中，我看到以下幾行：

• 使用控制台時也會發生相同的情況：

➜  bookmarker git:(master) ✗ bin/cake console

    Welcome to CakePHP v3.0.11 Console
    ---------------------------------------------------------------
    App : src
    Path: /Applications/AMPPS/www/projects/bookmarker/src/
    ---------------------------------------------------------------
    You can exit with `CTRL-C` or `exit`

Answer 1

方法_setPassword應該

 return $hasher->hash($value); 

代替

return $hasher.hash($value);
