您可以使用Flash Builder创建客户端应用程序,该应用程序可使用HTTP令牌执行单点登录(SSO)身份验证。 例如,假定您使用Flash Builder创建基于Web的应用程序。 接下来假设应用程序包含不同的视图,其中每个视图调用不同的AEM Forms操作。 您可以创建一个登录页面,让用户进行一次身份验证,而不是对每个Forms操作的用户进行身份验证。 一旦验证,用户便能够调用多个操作,而无需再次验证。 例如,如果用户已登录到工作区(或其他Forms应用程序),则用户无需再次进行身份验证。
尽管客户端应用程序包含执行SSO身份验证所需的应用程序逻辑,但AEM Forms用户管理执行实际的用户身份验证。 为了使用HTTP令牌对用户进行身份验证,客户端应用程序会调用身份验证管理器服务的authenticateWithHTTPToken
操作。 用户管理能够使用HTTP令牌来验证用户。 对于后续对AEM Forms的远程处理或Web服务调用,您无需传递身份验证凭据。
在阅读此部分之前,建议您熟悉使用远程调用AEM Forms。 (请参阅使用AEM Forms Remoting调用AEM Forms。)
使用SSO验证用户后,将调用以下名为MyApplication/EncryptDocument
的AEM Forms短期进程。 (有关此进程的信息(如其输入和输出值),请参阅短生命周期进程示例。)
此过程不基于现有的AEM Forms进程。 要遵循讨论如何调用此过程的代码示例,请使用Workbench创建一个名为MyApplication/EncryptDocument
的进程。 (请参阅使用Workbench。)
使用Flash Builder构建的客户端应用程序与在/um/login
和/um/logout
配置的用户管理器安全Servlet交互。 即,客户端应用程序在启动期间向/um/login
URL发送请求,以确定用户的状态。 然后,用户管理器将回复用户状态。 客户端应用程序和用户管理器安全Servlet使用HTTP进行通信。
请求格式
安全Servlet需要以下输入变量:
um_no_redirect
— 此值必须为 true
。此变量与向用户管理器安全Servlet发出的所有请求一起提供。 它还有助于安全Servlet区分来自Flex客户端或其他Web应用程序的传入请求。j_username
— 此值是在登录表单中提供的用户登录标识符值。j_password
— 此值是登录表单中提供的用户相应密码。j_password
值仅对于凭据请求是必需的。 如果未指定密码值,则安全Servlet会检查以确定您所使用的帐户是否已通过身份验证。 如果是,您可以继续;但是,安全servlet不会再次对您进行身份验证。
要正确处理i18n,请确保这些值为POST形式。
响应格式
在/um/login
配置的安全Servlet使用URLVariables
格式进行响应。 在此格式中,内容类型的输出为文本/纯文本。 输出包含由与号(&)字符分隔的名称值对。 响应包含以下变量:
authenticated
— 值为 true
或 false
。
authstate
— 此值可以包含以下值之一:
CREDENTIAL_CHALLENGE
— 此状态表示用户管理器无法通过任何方式确定用户的身份。要进行身份验证,需要用户的用户名和密码。SPNEGO_CHALLENGE
— 此状态的处理方式与相 CREDENTIAL_CHALLENGE
同。COMPLETE
— 此状态表示用户管理器能够验证用户。FAILED
— 此状态表示用户管理器无法验证用户。作为对此状态的响应,flex客户端可能会向用户显示错误消息。LOGGED_OUT
— 此状态表示用户已成功注销。assertionid
— 如果状态为, COMPLETE
则它包含用户的 assertionId
值。客户端应用程序可以获取用户的AuthResult
。
登录过程
当客户端应用程序启动时,您可以向/um/login
安全Servlet发出POST请求。 例如,https://<your_serverhost>:<your_port>/um/login?um_no_redirect=true
。 当请求到达用户管理器安全Servlet时,它会执行以下步骤:
lcAuthToken
的Cookie。 如果用户已登录到另一个Forms应用程序,则此Cookie存在。 如果找到Cookie,则验证其内容。如果安全Servlet找到与用户匹配的有效令牌,则安全Servlet允许您继续并响应authstate=COMPLETE
。 否则,安全Servlet将响应authstate=CREDENTIAL_CHALLENGE
。 以下列表说明了这些值:
Case authstate=COMPLETE
:指示用户已通过身份验证, assertionid
且值包含用户的断言标识符。此时,客户端应用程序可以连接到AEM Forms。 为该URL配置的Servlet可通过调用AuthenticationManager.authenticate(HttpRequestToken)
方法来获取用户的AuthResult
。 AuthResult
实例可以创建用户管理器上下文并将其存储在会话中。Case authstate=CREDENTIAL_CHALLENGE
:表示安全Servlet需要用户的凭据。作为响应,客户端应用程序可向用户显示登录屏幕,并将获取的凭据发送到安全Servlet(例如,https://<your_serverhost>:<your_port>/um/login?um_no_redirect=true&j_username=administrator&j_password=password)
)。 如果身份验证成功,则安全Servlet将响应authstate=COMPLETE
。如果身份验证仍然不成功,则安全Servlet将响应authstate=FAILED
。 为响应此值,客户端应用程序可显示一条消息以再次获取凭据。
而authstate=CREDENTIAL_CHALLENGE
则建议客户端以POST形式将获取的凭据发送到安全Servlet。
注销过程
当客户端应用程序注销时,您可以向以下URL发送请求:
https://<your_serverhost>:<your_port>/um/logout?um_no_redirect=true
在收到此请求时,用户管理器安全servlet将删除lcAuthToken
Cookie并使用authstate=LOGGED_OUT
做出响应。 客户端应用程序收到此值后,可以执行清理任务。
为了演示如何创建执行SSO身份验证的客户端应用程序,创建了一个示例客户端应用程序。 下图显示了客户端应用程序使用SSO验证用户时执行的步骤。
上图描述了客户端应用程序启动时发生的应用程序流。
applicationComplete
事件。ISSOManager.singleSignOn
。 客户端应用程序向用户管理器安全Servlet发送请求。ISSOManager
将调度SSOEvent.AUTHENTICATION_SUCCESS
。 作为响应,客户端应用程序显示主页。 在此示例中,主页将调用名为MyApplication/EncryptDocument的AEM Forms短期进程。ISSOManager
类调度SSOEvent.AUTHENTICATION_REQUIRED
事件。 客户端应用程序显示登录页面。ISSOManager.login
方法。 如果身份验证成功,则会导致步骤3。 否则,将触发SSOEvent.AUTHENTICATION_FAILED
事件。 客户端应用程序显示登录页面和相应的错误消息。客户端应用程序包含以下文件:
SSOStandalone.mxml
:表示客户端应用程序的主MXML文件。(请参阅创建SSOStandalone.mxml文件。)um/ISSOManager.as
:显示与单点登录(SSO)相关的操作。(请参阅创建ISSOManager.as文件。)um/SSOEvent.as
:将 SSOEvent
为SSO相关事件调度。(请参阅创建SSOEvent.as文件。)um/SSOManager.as
:管理与单点登录相关的操作并调度适当的事件。(请参阅创建SSOManager.as文件。)um/UserManager.as
:包含使用其WSDL调用身份验证管理器服务的应用程序逻辑。(请参阅创建UserManager.as文件。)views/login.mxml
:表示登录屏幕。(请参阅创建login.mxml文件。)views/logout.mxml
:表示注销屏幕。(请参阅创建logout.mxml文件。)views/progress.mxml
:表示进度视图。(请参阅创建progress.mxml文件。)views/remoting.mxml
:表示使用远程调用名为MyApplication/EncryptDocument的AEM Forms短期进程的视图。(请参阅创建remoting.mxml文件。)下图提供了客户端应用程序的可视表示形式。
请注意,有两个名为um和views的包。 在创建客户端应用程序时,请确保将文件放置在其正确的包中。 此外,请确保将adobe-remoting-provider.swc文件添加到项目的类路径中。 (请参阅包含AEM Forms Flex库文件。)

以下各节提供了描述客户端应用程序与用户管理器安全Servlet之间通信的其他详细信息。
在这种情况下,用户将首次尝试从客户端应用程序登录到AEM Forms。 (不存在与用户有关的上一会话。) 在applicationComplete
事件中,将调用SSOManager.singleSignOn
方法,以向用户管理器发送请求。
GET /um/login?um%5Fno%5Fredirect=true HTTP/1.1
用户管理器安全Servlet将以下值进行响应:
HTTP/1.1 200 OK
authenticated=false&authstate=CREDENTIAL_CHALLENGE
作为对此值的响应,将调度SSOEvent.AUTHENTICATION_REQUIRED
值。 因此,客户端应用程序会向用户显示登录屏幕。 凭据会提交回用户管理器安全Servlet。
GET /um/login?um%5Fno%5Fredirect=true&j%5Fusername=administrator&j%5Fpassword=password HTTP/1.1
用户管理器安全Servlet将以下值进行响应:
HTTP/1.1 200 OK
Set-Cookie: lcAuthToken=53630BC8-F6D4-F588-5D5B-4668EFB2EC7A; Path=/
authenticated=true&authstate=COMPLETE&assertionid=53630BC8-F6D4-F588-5D5B-4668EFB2EC7A
因此,调度了authstate=COMPLETE the SSOEvent.AUTHENTICATION_SUCCESS
。 如果需要,客户端应用程序可以执行进一步的处理。 例如,可以创建跟踪用户进行身份验证的日期和时间的日志。
在这种情况下,用户已经登录到AEM Forms,然后导航到客户端应用程序。 客户端应用程序在启动期间连接到User Manager安全Servlet。
GET /um/login?um%5Fno%5Fredirect=true HTTP/1.1
Cookie: JSESSIONID=A4E0BCC2DD4BCCD3167C45FA350BD72A; lcAuthToken=53630BC8-F6D4-F588-5D5B-4668EFB2EC7A
由于用户已通过身份验证,因此存在用户管理器Cookie,并将其发送到用户管理器安全Servlet。 然后,Servlet获取assertionId
值并验证该值是否有效。 如果该函数有效,则返回authstate=COMPLETE
。 否则,返回authstate=CREDENTIAL_CHALLENGE
。 以下是典型的响应:
HTTP/1.1 200 OK
authenticated=true&authstate=COMPLETE&assertionid=53630BC8-F6D4-F588-5D5B-4668EFB2EC7A
在这种情况下,用户不会显示登录屏幕,而是直接转到欢迎屏幕。
