从谷歌开发者控制台创建了一个项目并创建了一个服务帐户.下载了密钥库.我需要使用google admin sdk来创建/删除/访问用户.我看到了Admin SDK ON API和Auth-> API.由于范围错误而无法获得授权.

示例Java代码段

public boolean makeConnectionWithGoogleAPI(){

try{
           List<String> scopes = Arrays.asList("https://www.googleapis.com/auth/admin.directory.user",
                "https://www.googleapis.com/auth/admin.directory.user.readonly");

      HttpTransport httpTransport = new NetHttpTransport();
      JacksonFactory jsonFactory = new JacksonFactory();

      GoogleCredential credential = new GoogleCredential.Builder()
          .setTransport(httpTransport)
          .setJsonFactory(jsonFactory)
          .setServiceAccountId(clientEmail)
          .setServiceAccountUser(userId)
          .setServiceAccountScopes(scopes)
          .setServiceAccountPrivateKeyFromP12File(
              new java.io.File(privateKeyStoreLocation))
          .build();

      Directory admin =
          new Directory.Builder(httpTransport, jsonFactory, null)
          .setHttpRequestInitializer(credential).build();

      Directory.Users.List list = admin.users().list();
      Users users = list.execute();
      List<User> listUsers=users.getUsers();
      for(User user:listUsers){
          System.out.println(user.getId());
      }
      return true;
}catch(Exception e){
        e.printStackTrace();
}
  return false;
}
