如何在 google 驱动器中搜索特定文件？

Question

我从 Google 开发者网站上获取了这段代码，并对其进行了一些修改。但我想要的是搜索 Google 驱动器中存在的文件。我不知道在哪里给 folder id 找到文件？。如果它们存在，则 okay, the files are found 消息。如果不是那么 files are not found

import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request
from google.oauth2.credentials import Credentials

SCOPES = ['https://www.googleapis.com/auth/drive']    
def main():
    creds = None
    if os.path.exists('token.json'):
        creds = Credentials.from_authorized_user_file('token.json', SCOPES)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
        with open('token.json', 'w') as token:
            token.write(creds.to_json())

    service = build('drive', 'v3', credentials=creds)
    filename = 'Image'
    page_token = None
    while True:
        response = service.files().list(q="name contains '"+filename+"'",
                                              spaces='drive',
                                              fields='nextPageToken, files(id, name)',
                                              pageToken=page_token).execute()
        for file in response.get('files', []):
            # Process change
            print('Found file: %s (%s)' % (file.get('name'), file.get('id')))
        page_token = response.get('nextPageToken', None)
        if page_token is None:
            break

if __name__ == '__main__':
    main()

I want is to search for the files that are present in Google drive.

正常 file.list 将 return 您的 google 驱动器根目录中的所有文件无特殊顺序。

I don't know where to give the folder id to find the files?.

要搜索特定文件夹中的所有文件，您需要使用 Q 搜索参数的 parents in 选项。

response = service.files().list(q="parents in '"+ Folder ID +"'",
                                              spaces='drive',
                                              fields='nextPageToken, files(id, name)',
                                              pageToken=page_token).execute()

我建议执行如下操作，首先搜索文件夹，这将帮助您找到可以在上面的请求中使用的文件夹的文件 ID。

response = service.files().list(q="name = '"+ folder name +"' and mimeType = 'application/vnd.google-apps.folder'",
                                                  spaces='drive',
                                                  fields='nextPageToken, files(id, name)',

您可能想查看 Search for files and folders 它有一些有趣的示例。

If they exist then okay, the files are found message. If not then files are not found

如果您正在搜索特定的文件名，而该名称不存在，您可能会从 API 返回一个空响应，而不是错误。所以简单地测试是否有任何文件 returned 会告诉你是否找到文件。
