Question

我正在编写一个试图通过Drive Api v3连接到Google驱动器的python脚本

FLOW = OAuth2WebServerFlow(client_id="****************************",\
                           client_secret="************************",\
                           scope="https://www.googleapis.com/auth/drive",
                           redirect_uri="urn:ietf:wg:oauth:2.0:oob",
                           user_agent="PythonFileEditor/1.0")

OUT_PATH = os.path.join(os.path.dirname(__file__), 'out')
CREDS_FILE = os.path.join(os.path.dirname(__file__), 'credentials.json')

if not os.path.exists(OUT_PATH):
    os.makedirs(OUT_PATH)

storage = Storage(CREDS_FILE)
credentials = storage.get()

if credentials is None:

    authorize_url = FLOW.step1_get_authorize_url()
    print 'Go to the following link in your browser: ' + authorize_url
    code = raw_input('Enter verification code: ').strip()
    try:
        credentials = FLOW.step2_exchange(code)
    except SystemError:
        print SystemError

    storage.put(credentials)

'''Authintication Process is Over'''

http        = httplib2.Http()
http        = credentials.authorize(http)

auth2tocken = gdata.gauth.OAuth2TokenFromCredentials(credentials)


service = build('drive', 'v3', http=http)

results = service.files().list(\
    pageSize=10,fields="nextPageToken, files(id, name)").execute()

items = results.get('files', [])
if not items:
    print('No files found.')
else:
    print('Files:')
    for item in items:

        print('{0} ({1})'.format(item['name'].encode('utf8'), item['id']))
        if item.get('name')=='TestPY.txt':

            fileId=item['id']
            request = service.files().get_media(fileId=fileId)
            fh = io.FileIO(item['name'])
            downloader =MediaIoBaseDownload(fh,request)
            done = False
            while done is False:
                status, done = downloader.next_chunk()
                print "Download %d%%." % int(status.progress() * 100)

这个脚本，尝试下载名为＆＃34; TestPY.txt＆＃34;的文件。从我的谷歌驱动器到我的本地机器，验证过程似乎很好，因为我可以获取文件名称和ID，但当我尝试下载我的文件时，API抛出此异常

raise HttpError(resp, content, uri=self._uri)
googleapiclient.errors.HttpError: <HttpError 403 when requesting https://www.googleapis.com/drive/v3/files/0Bw2Q7p_e5q0-SFpGUURMSWptV3M?alt=media returned "The user has not granted the app ************** read access to the file 0Bw2Q7p_e5q0-SFpGUURMSWptV3M.">

我的范围是完全特权的，所以理论上我应该能够下载/上传/读/写任何文件！

任何人都能指出正确的方向吗？

谢谢大家。

Answer 1

我想通了，我之前使用过/metadata.readonly标志，而且我没有相应地更新我的cridentials文件。

所以即使我的范围现在更大，驱动器也看不到它，因为它没有反映在我的Json文件中。

Answer 2

转到您的文件位置并删除token.pickle文件。

重新运行该文件，它将起作用。

谷歌驱动器api验证了Http请求返回403响应＆＃34;用户未授予应用程序xxxx对文件xxxxxx的读取访问权限＃34;
