执行 Google 应用全域授权

Perform Google Apps Domain-Wide Delegation of Authority

我正在尝试在我的应用程序服务帐户和我的组织(在 admin.google.com 上)之间进行全域授权。我跟着 this 指南,大约三遍,我不知道我错过了什么,它不起作用。我的应用程序无法对组织内的用户进行拟人化。

API 的回复说:

 Exception in thread "main" com.google.api.client.auth.oauth2.TokenResponseException: 403 Forbidden
{
  "error" : "access_denied",
  "error_description" : "Requested client not authorized."
}

这是我的唯一代码,用于测试:

 String emailAddress = "zzzzzzzzzzzzz@developer.gserviceaccount.com";
            JsonFactory JSON_FACTORY =          JacksonFactory.getDefaultInstance();
            HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();

            //scopes
            List scopes = new ArrayList();
            scopes.add(DriveScopes.DRIVE);
            scopes.add(DriveScopes.DRIVE_APPDATA);
            scopes.add(DriveScopes.DRIVE_APPS_READONLY);
            scopes.add(DriveScopes.DRIVE_FILE);

            GoogleCredential credential = new GoogleCredential.Builder()
            .setTransport(httpTransport)
            .setJsonFactory(JSON_FACTORY)
            .setServiceAccountId(emailAddress)
            .setServiceAccountPrivateKeyFromP12File(new File("valid_path_to_secrets.p12"))
            .setServiceAccountScopes(scopes)
            .setServiceAccountUser("test@mydomain.com.br") // HERE THE USER I WANT TO PERSONIFICATE
            .build();

            Drive drive = new Drive.Builder(httpTransport, JSON_FACTORY, credential).setApplicationName("Test").build();

            String myName = drive.about().get().execute().getName();
            com.google.api.services.drive.Drive.Files.List files = drive.files().list();
            FileList fileList = files.execute();
            List<com.google.api.services.drive.model.File> xFiles = fileList.getItems();

            System.out.println("here");
            for (com.google.api.services.drive.model.File f : xFiles){
                System.out.println("DEBUG "+f.getOriginalFilename());
                System.out.println(f.getDownloadUrl());
                System.out.println(f.getAlternateLink());
                System.out.println(f.getOwnerNames().get(0));
                System.out.println(f.getFileSize());
            }
        }

        }

如果我注释标记为 (setServiceAccountUser("test@mydomain.com.br")) 的行,应用程序可以运行,但我想将此用户拟人化 test。这就是提供本指南的目的,向 mydomain.com.br.

内的所有用户授予访问权限

在 Google 指南的 Delegate domain-wide authority to your service account 部分,如前所述,我遵循了所有步骤,注意步骤编号 6:要在 [= 上添加范围18=] 在 Security 部分下。 (google 应用程序的管理配置)

您已授权 1 个驱动器范围的客户端 ID:

https://www.googleapis.com/auth/drive

此范围存储在常量 DriveScopes.DRIVE 下的 Java 中。

但是当您在代码中创建凭据时,您需要 4 个范围:

scopes.add(DriveScopes.DRIVE);
scopes.add(DriveScopes.DRIVE_APPDATA);
scopes.add(DriveScopes.DRIVE_APPS_READONLY);
scopes.add(DriveScopes.DRIVE_FILE);

我同意,由于 DriveScopes.DRIVE 是一个包含云端硬盘中其他范围的范围,因此获得 DriveScopes.DRIVE 的授权意味着您获得所有其他范围的授权似乎很正常驱动范围。

然而情况并非如此,您必须在 Security 部分中指定 all 您计划使用的范围。在你的情况下是:

https://www.googleapis.com/auth/drive
https://www.googleapis.com/auth/drive.appdata
https://www.googleapis.com/auth/drive.apps.readonly
https://www.googleapis.com/auth/drive.file

但是由于所有这些范围都已包含在 https://www.googleapis.com/auth/drive 中,您也可以简单地从 Java 代码中删除其他范围。这就是我要做的:

...
List scopes = new ArrayList();
scopes.add(DriveScopes.DRIVE);
//No other scope

GoogleCredential credential = new GoogleCredential.Builder()
...
