当前试图设置Yesod.Auth.Email，但在获得验证URL后遇到了一些问题。
在"设置密码"页面上（带有"新密码"one_answers"确认"），输入密码，并且在确认框中相同后，它始终返回"密码"不匹配，请再次尝试"。p>这是记录的请求，
POST /auth/page/email/set-password
Params: [("_token","wcpv0LhJfy"),("new","1234"),("confirm","1234")]
Request Body: _token=wcpv0LhJfy&new=1234&confirm=1234
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Status: 303 See Other 0.002459s
表明它们确实应该匹配。
查看处理程序postPasswordR的源代码，这对我来说并不完全清楚为什么会失败，因为这不是您在instance YesodAuthEmail App中覆盖的东西？
最小示例
直接从Yesod书中的电子邮件作物部分中取出，并保存为Main.hs，

安装stack install yesod persistent-sqlite后，它将使用stack runghc Main.hs运行。
我的Stackage LTS版本是lts-7.14，我正在运行GHC版本8.0.1.20161117。
仍然得到相同的结果。
您必须启用CSRF中间件才能使其正常工作。我将相应地更新书籍示例。错误消息显然不好，应该改进。要使您的代码正常工作，请在使用基础类型的Yesod Typeclass实例时添加此内容：
yesodMiddleware = defaultCsrfMiddleware . defaultYesodMiddleware
