Answer 1

您可以在此处查看有关如何在云端硬盘中列出文件的示例： https ://developers.google.com/drive/api/v3/search-files。您需要构建一个列出文件夹中文件的查询：使用

q = "'1234' in parents"

其中 1234 是您要列出的文件夹的 ID。您可以修改查询以列出特定类型的所有文件（例如文件夹中的所有 jpeg 文件）等。

Answer 2

这是一个 hacky-yet-successful 解决方案。这实际上是从一个特定的 Google Drive 文件夹（在本例中是一个名为“thumbnails”的文件夹） 获取 所有文件。我需要从特定文件夹中获取（不仅仅是列出）所有文件并对它们执行图像调整，因此我使用了以下代码：

 `# First, get the folder ID by querying by mimeType and name
folderId = drive.files().list(q = "mimeType = 'application/vnd.google-apps.folder' and name = 'thumbnails'", pageSize=10, fields="nextPageToken, files(id, name)").execute()
# this gives us a list of all folders with that name
folderIdResult = folderId.get('files', [])
# however, we know there is only 1 folder with that name, so we just get the id of the 1st item in the list
id = folderIdResult[0].get('id')

# Now, using the folder ID gotten above, we get all the files from
# that particular folder
results = drive.files().list(q = "'" + id + "' in parents", pageSize=10, fields="nextPageToken, files(id, name)").execute()
items = results.get('files', [])

# Now we can loop through each file in that folder, and do whatever (in this case, download them and open them as images in OpenCV)
for f in range(0, len(items)):
    fId = items[f].get('id')
    fileRequest = drive.files().get_media(fileId=fId)
            fh = io.BytesIO()
            downloader = MediaIoBaseDownload(fh, fileRequest)
            done = False
            while done is False:
                status, done = downloader.next_chunk()
    fh.seek(0)
    fhContents = fh.read()

    baseImage = cv2.imdecode(np.fromstring(fhContents, dtype=np.uint8), cv2.IMREAD_COLOR)
