下面的代码示例演示如何扩展Login控件。The following code example demonstrates how you can extend the Login control. 控件包含一个DropDownList控件, 该控件使用户可以选择要使用其进行身份验证的成员资格提供程序。 CustomLoginThe CustomLogin control includes a DropDownList control that lets users choose which membership provider they are authenticated with. (这些提供程序在 web.config 中进行配置。)在方法中MembershipProvider , 属性设置为DropDownList控件的选定值。 OnLoggingIn(These providers are configured in Web.config.) In the OnLoggingIn method, the MembershipProvider property is set to the selected value of the DropDownList control.

重要

此示例包含一个文本框, 该文本框接受用户输入, 这是一个潜在的安全威胁。This example contains a text box that accepts user input, which is a potential security threat. 默认情况下,ASP.NET 网页验证用户输入是否不包含脚本或 HTML 元素。By default, ASP.NET Web pages validate that user input does not include script or HTML elements. 有关详细信息,请参阅脚本侵入概述For more information, see Script Exploits Overview.

介绍Introduction

Login控件是一个复合控件, 可提供对网站上的用户进行身份验证所需的所有常见 UI 元素。The Login control is a composite control that provides all the common UI elements needed to authenticate a user on a Web site. 所有登录方案都需要以下三个元素:The following three elements are required for all login scenarios:

  • 用于标识用户的唯一用户名。A unique user name to identify the user.

  • 用于验证用户标识的密码。A password to verify the identity of the user.

  • 用于将登录信息发送到服务器的登录按钮。A login button to send the login information to the server.

Login控件还提供了以下支持其他函数的可选 UI 元素:The Login control also provides the following optional UI elements that support additional functions:

  • 密码提示的链接。A link for a password reminder.

  • "记住我" 复选框, 用于在会话之间保留登录信息。A Remember Me checkbox for retaining the login information between sessions.

  • 在登录时遇到问题的用户的帮助链接。A Help link for users who are having trouble logging in.

  • 将用户重定向到注册页的 "注册新用户" 链接。A Register New User link that redirects users to a registration page.

  • 登录窗体上显示的说明文本。Instruction text that appears on the login form.

  • 当用户单击 "登录" 按钮时显示的自定义错误文本, 不填充 "用户名" 或 "密码" 字段。Custom error text that appears when the user clicks the login button without filling in the user name or password fields.

  • 登录失败时显示的自定义错误文本。Custom error text that appears if the login fails.

  • 登录成功后发生的自定义操作。A custom action that occurs when login succeeds.

  • 如果用户已登录到站点, 则为隐藏登录控件的一种方法。A way to hide the login control if the user is already logged in to the site.

有关显示必需的控件和可选的控件的表, 请参见LayoutTemplate属性。For a table showing which controls are required and which are optional, see LayoutTemplate property.

备注

如果你不熟悉 ASP.NET 中提供的登录控件集, 请参阅ASP.NET Login Controls 概述, 然后继续。If you are not familiar with the set of login controls available in ASP.NET, see ASP.NET Login Controls Overview before continuing. 有关与登录控件和成员资格相关的其他主题的列表, 请参阅使用成员身份管理用户For a list of other topics related to login controls and membership, see Managing Users by Using Membership.

重要

接受用户输入是潜在的安全威胁。Accepting user input is a potential security threat. 恶意用户可以发送旨在公开漏洞或运行尝试生成的密码的程序的数据。Malicious users can send data that is intended to expose vulnerabilities or run programs that try generated passwords. 若要在使用用户输入时提高安全性, 应使用控件的验证功能并保护为控件配置的任何数据访问接口。To improve security when working with user input, you should use the validation features of your control and secure any data providers that are configured for your control. 有关详细信息, 请参阅保护登录控件Web 应用程序的基本安全实践以及保护成员身份For more information, see Securing Login Controls, Basic Security Practices for Web Applications, and Securing Membership.

Login控件使用成员资格提供程序来获取用户凭据。The Login control uses a membership provider to obtain user credentials. 除非另行指定, Login否则控件将使用 web.config 文件中定义的默认成员资格提供程序。Unless you specify otherwise, the Login control uses the default membership provider defined in the Web.config file. 若要指定其他提供程序, 请MembershipProvider将属性设置为应用程序的 web.config 文件中定义的成员资格提供程序名称之一。To specify a different provider, set the MembershipProvider property to one of the membership provider names defined in your application's Web.config file. 有关详细信息, 请参阅成员资格提供程序For more information, see Membership Providers.

如果要使用自定义身份验证服务, 可以使用OnAuthenticate方法来调用服务。If you want to use a custom authentication service, you can use the OnAuthenticate method to call the service.

样式和模板Styles and Templates

Login控件的外观可通过模板和样式设置完全自定义。The appearance of the Login control is fully customizable through templates and style settings. 所有 UI 文本消息还可通过Login类的属性进行自定义。All UI text messages are also customizable through properties of the Login class. 默认的接口文本会根据服务器上的区域设置自动进行本地化。The default interface text is automatically localized based on the locale setting on the server.

如果控件是用模板自定义的, AccessKey则将忽略属性TabIndex和属性。 LoginIf the Login control is customized with templates, then the AccessKey property and the TabIndex property are ignored. 在这种情况下, AccessKey请直接设置TabIndex每个模板子控件的属性和属性。In this case, set the AccessKey property and the TabIndex property of each template child control directly.

Login文本框 (如UserNamePassword) 表示的控件属性可在页面生命周期的所有阶段中访问。Login control properties represented by text boxes, such as UserName and Password, are accessible during all phases of the page life cycle. 控件将通过TextChanged文本框触发的事件选取最终用户所做的任何更改。The control will pick up any changes made by the end user by means of the TextChanged event triggered by the textboxes.

备注

如果在WizardStep对象中Login嵌入控件, 则在对用户进行ActiveStepIndex身份验证时Page_Load , 显式设置事件处理程序中的属性。If you embed the Login control in a WizardStep object, explicitly set the ActiveStepIndex property in a Page_Load event handler if the user is authenticated. Wizard此方案中, 控件不会自动WizardStep前进到下一个对象。The Wizard control does not automatically advance to the next WizardStep object in this scenario.

下表列出Login了控件样式属性, 并说明了每个样式属性影响的 UI 元素。The following table lists the Login control style properties and explains which UI element each style property affects. 有关每种样式应用于的属性的列表, 请参阅各个样式属性的文档。For a list of which properties each style applies to, see the documentation for the individual style properties.

Style 属性Style property 受影响的 UI 元素UI element affected
BorderPadding 控件内容和控件的边框之间的空间。The space between the control contents and the control's border.
CheckBoxStyle "记住我" 复选框。Remember Me checkbox.
FailureTextStyle 登录失败文本。Login failure text.
InstructionTextStyle 页面上告知用户如何使用控件的说明文本。Instructional text on the page that tells users how to use the control.
LabelStyle 所有输入字段 (如文本框) 的标签。Labels for all input fields, such as text boxes.
TextBoxStyle 文本输入字段。Text entry input fields.
TitleTextStyle 标题文本。Title text.
ValidatorTextStyle 由于验证错误而导致登录尝试失败时向用户显示的文本。Text displayed to the user when a login attempt is unsuccessful due to validation errors.
HyperLinkStyle 指向其他页面的链接。Links to other pages.
LoginButtonStyle "登录" 按钮。Login button.

验证分组Validation Groupings

UserName和属性Password具有与之关联的控件,以防止用户提交页面,RequiredFieldValidator而不提供所需的信息。The UserName and Password properties have RequiredFieldValidator controls associated with them to prevent users from submitting the page without providing required information.

控件使用验证组, 以便可以单独验证同一页Login上的其他字段。 LoginThe Login control uses a validation group so that other fields on the same page as the Login control can be validated separately. 默认情况下, ID Login控件的属性用作验证组的名称。By default, the ID property of the Login control is used as the name of the validation group. 例如, Login ID 为 "Login1" 的控件将使用验证组名称 "Login1"。For example, a Login control with the ID "Login1" will use a validation group name of "Login1". 如果要设置该Login控件所属的验证组, 则必须为该控件设置模板并更改验证组名称。If you want to set the validation group that the Login control is part of, you must template the control and change the validation group name.

应用 CSS 样式Applying CSS Styles

Login控件使您可以在标记中指定 CSS 样式规则。The Login control lets you specify CSS style rules in markup. 如果使用模板来自定义Login控件的外观, 则可以在模板的标记中指定 CSS 样式。If you use templates to customize the appearance of the Login control, you can specify CSS styles in the markup in the templates. 在这种情况下, 不需要额外的外部表。In that case, no extra outer table is required. 您可以通过将RenderOuterTable属性设置为来false阻止呈现该表。You can prevent the table from being rendered by setting the RenderOuterTable property to false.

可访问性Accessibility

有关如何配置此控件以生成符合辅助功能标准的标记的信息, 请参阅Visual Studio 中的辅助功能和 ASP.NETASP.NET 控件和辅助功能For information about how to configure this control so that it generates markup that conforms to accessibility standards, see Accessibility in Visual Studio and ASP.NET and ASP.NET Controls and Accessibility.
