WebSecurity.Login(userName, password, persistCookie)

示例

C# 示例

}

{
<p>用户名或密码错误。</p>
}

VB 示例

if WebSecurity.Login(username,password)
<p>欢迎</p>
else
<p>用户名或密码错误</p>
end if

参数

参数 类型 描述
userName String 用户名
password String 用户密码
persistCookie String 如果要将 Cookie 中的身份验证令牌保留在当前会话之外,则为 true;否则为 false。默认值为 false。

返回值

类型 描述
Boolean 如果用户已登录,则为 true,否则为 false

备注

当用户登录时,ASP.NET 会在 Cookie 中设置身份验证令牌,以便 ASP.NET 在后续请求中知道用户已登录。如果 persistCookie 为 false,则该令牌仅在用户关闭浏览器之前有效。

如果以下情况发生,则对 WebSecurity 对象的任何访问都会引发 InvalidOperationException

  • 未调用 InitializeDatabaseConnection() 方法
  • SimpleMembership 未初始化(或在网站配置中被禁用)
