Google Admin Directory API返回400个错误请求

我正在尝试使用Google Admin SDK的Java客户端，特别是Directory API。 它基于GoogleCredentials的使用，就像Google Drive API一样。 但是，与Google云端硬盘驱动器不同的是，我收到了400条错误的目录请求错误。 我按如下方式设置API： 

Directory directory = new Directory.Builder(TRANSPORT, FACTORY, credential).build(); Directory.Users.List list = directory.users().list(); Users users = list.execute();

最后一个execute（）生成列在post底部的错误和堆栈跟踪。 我正在使用以下范围来授权自己。 我也可以使用Drive API。 

 https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/drive https://www.googleapis.com/auth/admin.directory.user

访问Drive API就像魅力一样。 我可以毫无问题地请求文件。 但是，如果我对Directory API执行简单操作，则会收到下面列出的错误和堆栈跟踪。 我应该提一下，Drive API和Directory API都指的是我是管理员的Google Apps域名。 我还在Google API控制台中启用了这两个API。 对于其他人，我无法弄清楚我做错了什么，我想知道是否有其他人看到类似的东西或者有通过Java客户端访问这个API的经验。

谢谢，

问题是您没有指定要使用的用户或要使用的域，

你需要在这里添加这些信息： 

 Directory directory = new Directory.Builder(TRANSPORT, FACTORY, credential).build(); Directory.Users.List list = directory.users().list(); list.setCustomer("name.surname@yourdomain.com"); Users users = list.execute();

现在，如果您有权限问题，则错误的返回码将为403 =授权问题。

解决方案是： 

  HttpTransport httpTransport = new NetHttpTransport(); JacksonFactory jsonFactory = new JacksonFactory(); GoogleCredential credential; Collection SCOPES = new ArrayList(); SCOPES.add("https://www.googleapis.com/auth/admin.directory.user"); credential = new GoogleCredential.Builder().setTransport(httpTransport) .setJsonFactory(jsonFactory) .setServiceAccountId(SERVICE_ACCOUNT_EMAIL) .setServiceAccountUser("adminEmail@yourDomain.com") .setServiceAccountScopes(SCOPES) .setServiceAccountPrivateKeyFromP12File( new java.io.File(SERVICE_ACCOUNT_PKCS12_FILE_PATH)) .build(); Directory directory = new Directory.Builder(httpTransport, jsonFactory, credential).build(); Directory.Users.List list = directory.users().list(); list.setDomain("yourDomain.com"); Users users = list.execute();

SERVICE_ACCOUNT_PKCS12_FILE_PATH =密钥的文件位置（API控制台）SERVICE_ACCOUNT_EMAIL =来自API COnsole的服务帐户

使用服务帐户https://developers.google.com/drive/delegation方法从域控制面板添加范围

并在API控制台中激活Admin SDK。

如果您正在使用Maven，只需将以下内容添加到您的pom.xml： 

  com.google.apis google-api-services-admin directory_v1-rev4-1.15.0-rc
