WebSecurity - GeneratePasswordResetToken()


❮ WebSecurity

定义

GeneratePasswordResetToken() 方法生成一个密码重置令牌,可以发送到用户的电子邮件中。


C# 和 VB 语法

WebSecurity.GeneratePasswordResetToken(userName, expiration)

参数

参数 类型 描述
userName 字符串 用户名
expiration 整数 令牌过期之前的分钟数。默认值为 1440(24 小时)

返回值

类型 描述
字符串 重置令牌。

错误和异常

如果以下情况发生,对 WebSecurity 对象的任何访问都会抛出 InvalidOperationException 异常:

  • InitializeDatabaseConnection() 方法尚未被调用
  • SimpleMembership 未初始化(或在网站配置中禁用)

备注

如果用户忘记了他的密码,请使用 ResetPassword() 方法。ResetPassword() 方法需要密码 重置令牌

确认令牌可以通过 CreateAccount()CreateUserAndAccount()GeneratePasswordResetToken() 方法创建。

可以通过代码重置密码,但常见做法是向用户发送电子邮件(包含令牌和指向页面的链接),以便他可以使用新令牌确认新密码。

@{
newPassword = Request["newPassword"];
confirmPassword = Request["confirmPassword"];
token = Request["token"];
if IsPost
{
    // 为了节省空间,这里省略了输入测试
    retunValue = ResetPassword(token, newPassword);
}
}
<h1>更改密码</h1>

<form method="post" action="">

<label for="newPassword">新密码:</label>
<input type="password" id="newPassword" name="newPassword" title="新密码" />

<label for="confirmPassword">确认密码:</label>
<input type="password" id="confirmPassword" name="confirmPassword" title="确认新密码" />

<label for="token">密码令牌:</label>
<input type="text" id="token" name="token" title="密码令牌" />

<p class="form-actions">
<input type="submit" value="更改密码" title="更改密码" />
</p>

</form>
