Google Drive API files().list 只为整个组织返回一个文件

Question

我有以下代码从 GoogleDrive 获取整个组织的所有文件：

    def list_files(self):
        results = self._service_v3.files().list().execute()
        items = results.get('files', [])
        return items

问题是该方法只返回一个文件（Getting started.pdf）

我的整个代码如下所示：

class GoogleDriveModule(object):
    def __init__(self, config):
        credentials = service_account.Credentials.from_service_account_file(
        config['credentials-file'], scopes=config['resource-scopes'])
        self._service_v3 = build('drive', 'v3', credentials=credentials)

        def list_files(self):
            results = self._service_v3.files().list().execute()
            items = results.get('files', [])
            return items

如何检索驱动器中的所有文件？

Answer 1

您需要为要从中检索文件的目标用户委派凭据 [1]。您可以使用 google.oauth2 库 [2] 中服务帐户模块中的 with_subject 函数来执行此操作，例如：

from googleapiclient.discovery import build
import google.auth.transport.requests
from google.oauth2 import service_account

credentials = service_account.Credentials.from_service_account_file(
    SERVICE_ACCOUNT_FILE, scopes=SCOPES)

delegated_credentials = credentials.with_subject('targetUser@example.com')
delegated_credentials.refresh(google.auth.transport.requests.Request())

service = build('drive', 'v3', credentials=delegated_credentials)
