Apache flex 如何从Flex/Flash登录Drupal用户（或获取当前登录的用户）？
我有一个从Drupal页面托管的Flash应用程序。Flash应用程序的某些部分应可供所有用户使用，但某些部分应仅可供登录用户使用。具体的角色并不重要，只是他们是网站的任何授权用户 在Flash中，我可以通过屏幕抓取？q=用户页面来检测用户是否登录，但这非常脆弱。正确的方法是什么？如果需要，我可以安装其他模块，但它们需要与Drupal 6兼容，而不是与Drupal 5兼容 同样，如果当前没有用户登录，我如何获取他们提供给我的用户名和密码并登录或确定密码不正确？正确的解决方案 你可能想看看类似的东西。基本上，您希望将用户服务公开给您的flash应用程序，这样您就可以通过XML-RPC或您选择的任何实现发送请求，以获取信息，例如当前登录的用户具有什么访问权限，或者使用用户名x和密码y登录此用户等等 快速自己动手解决方案 如果您熟悉模块开发，您可以快速创建自己的模块，以获得所需的功能，而无需经过真正的web服务层。下面是一个快速示例，创建一个名为myservices的模块：Apache flex 如何从Flex/Flash登录Drupal用户（或获取当前登录的用户）？,apache-flex,flash,drupal,Apache Flex,Flash,Drupal,我有一个从Drupal页面托管的Flash应用程序。Flash应用程序的某些部分应可供所有用户使用，但某些部分应仅可供登录用户使用。具体的角色并不重要，只是他们是网站的任何授权用户 在Flash中，我可以通过屏幕抓取？q=用户页面来检测用户是否登录，但这非常脆弱。正确的方法是什么？如果需要，我可以安装其他模块，但它们需要与Drupal 6兼容，而不是与Drupal 5兼容 同样，如果当前没有用户登录，我如何获取他们提供给我的用户名和密码并登录或确定密码不正确？正确的解决方案 你可能想看看类似的东

如果您通过身份验证，它只会返回yes，如果不是no，等等。。。您可以在flash应用程序中选择它。我可以使用Drupal的系统和用户服务实现这一点： 安装 启用系统和用户服务 对于下面的代码，请禁用API密钥。或者让它们处于启用状态并提供额外的参数 已验证用户和匿名用户访问服务的权限 在撰写本文时，AMFPHP服务尚未移植到Drupal6，因此我使用了XMLRPC。为了使用ActionScript中的XMLRPC，我使用了位于的帮助程序库。这个库是为ActionScript2编写的，所以将它与Flex3一起使用需要我对其进行修补，正如jameshyu在2008年5月10日的“向下滚动页面并搜索评论”中所述 完成所有这些先决条件后，您可以检查当前登录的用户（如果有）和/或使用如下代码登录用户 以下是实际实现登录的模块：

我知道这与最初发表这篇文章的时候相比还有很长的路要走，但是如果你仍然对这篇文章感兴趣，并且从来没有花时间对它进行过很多研究，那么我就想出了如何通过flash文档成功地处理登录。嵌入的或外部的。它甚至不需要在系统上安装AMFPHP。这很好，因为我上次检查AMFPHP所依赖的服务模块时，该模块还没有建议的状态 我在这里设置了一个演示页面： 您可以登录和注销，它将检测您是否已经登录。这项工作仍在进行中，但大部分 你需要的东西已经为你准备好了 如果您想查看文档并想要源代码的副本，请在此处找到所有这些内容：
我希望这有帮助。我应该在下周的某个时候对该演示进行更新，所以如果您想要我在文章中提到的其他一些功能，请回头查看。我知道这与最初制作此文章的时间相比还有很长的路要走，但是如果您仍然对此感兴趣，并且从未花时间对其进行过大量研究，我想出了如何通过flash文档成功处理登录。嵌入的或外部的。它甚至不需要在系统上安装AMFPHP。这很好，因为我上次检查AMFPHP所依赖的服务模块时，该模块还没有建议的状态 我在这里设置了一个演示页面： 您可以登录和注销，它将检测您是否已经登录。这仍然是一项正在进行的工作，但是你需要的大部分东西都已经为你准备好了 如果您想查看文档并想要源代码的副本，请在此处找到所有这些内容： 我希望这有帮助。我应该在下周的某个时候对这个演示进行更新，所以如果你想要我在帖子中提到的其他一些功能，请回头看看
