如何使用Java Google Admin SDK API删除用户

时间：2017-07-10 16:08:17

标签： java google-admin-sdk

我使用了Java Quickstart并获得了一个正常运行的应用程序，该应用程序只显示连接到登录帐户的所有用户的完整列表。我已经浏览了Java文档，我发现的唯一与删除用户相关的是＆＃34; setDeletionTime＆＃34;在User类中，但我尝试使用虚拟帐户并将时间设置为＆＃34; null＆＃34;并试图创建一个设置为今天的时间，并且都不能删除用户。我不知道我在这里缺少什么。

我正在使用的代码，其中大部分都是从google快速入门中复制的

答案 0 :(得分：0)

在阅读了我可以在谷歌提供的所有内容后，我终于明白了......我想。我将在这里解释并将其作为答案，因为它有效;但是，如果我做错了，请告诉我。无论如何，这就是我所做的：

首先是第一件事。每个动作（据我所知）都通过http作为一个带有命令的URL。这意味着为了使任何事情发生，你必须有一个传输（由HttpTransport类给出）和一个工厂（由HttpRequestFactory类给出）来创建持有的HttpRequest对象动作/命令。

我们要做的请求是在“删除用户帐户”下显示here的DELETE请求

这可以通过以下方式完成：

HttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
HttpRequestFactory HTTP_REQUEST_FACTORY = HTTP_TRANSPORT.createRequestFactory();
HttpRequest deleteRequest = HTTP_REQUEST_FACTORY.buildDeleteRequest(new GenericUrl("https://www.googleapis.com/admin/directory/v1/users/userkey"));

但等等！我们在这里缺少一个非常重要的 key 元素。我们必须为Factory提供正确的凭据以标记标题。基本上是告诉谷歌我们能够删除用户。那我们该怎么做呢？

首先，我们必须设置范围，我们想要访问的内容。我们的范围是ADMIN_DIRECTORY_USER。像这样设置范围:(如果你已经完成了这个程序，请确认你在.credentials目录中删除文件!!!!）

List<String> SCOPES = Arrays.asList(DirectoryScopes.ADMIN_DIRECTORY_USER);

接下来我们需要一个凭证对象。这可以通过使用google在quickstart（authorize方法）中提供的方法来完成。要将凭证提供给我们的工厂，我们只需通过传递凭证对象来编辑上面的行：

HttpRequestFactory HTTP_REQUEST_FACTORY = HTTP_TRANSPORT.createRequestFactory(credentials);

注意：不要从HttpRequestInitializer方法传递credentials.getRequestInitializer()，因为这是空的（至少对我来说，这可能就像我正在做的那样，但我宁愿不尝试）。
