我在laravel 5.2中开发了一个项目，我目前在密码重置工作时遇到了麻烦。目前我正在寻找正确的电子邮件字段，并让用户请求密码重置电子邮件，并附带重置链接，然后在用户点击电子邮件中的链接后，将向用户显示更改密码的表单。当他们提交新密码时，会出现此错误：
Connection.php第729行中的QueryException：
SQLSTATE [42S22]：未找到列：1054未知列＆＃39; password_confirmation＆＃39;在＆＃39; where子句＆＃39; （SQL：从all_user中选择* user_email = ... @ hotmail.com和password_confirmation = 123456限制1）
我不知道为什么在sql语句中检查一个名为password_confirmation的字段。尝试获取用户以便它可以执行密码重置，从而导致此错误。这是在PasswordBroker.php文件和getUser函数中。更具体地说，行$ user = $ this-＆gt; users-＆gt; retrieveByCredentials（$ credentials）;
我目前修改的代码：
