python - PyDrive 2.0 – AuthenticationError：在重定向中找不到代码

问题描述

设置

我正在使用 PyDrive 2.0 连接到 Google Drive API。

def connect_google_drive_api():
    
    import os   
        
    # use Gdrive API to access Google Drive
    os.chdir('/Users/my/fol/ders/access_google_drive')
    from pydrive.auth import GoogleAuth
    from pydrive.drive import GoogleDrive
    
    gauth = GoogleAuth()
    gauth.LocalWebserverAuth() # client_secrets.json need to be in the same directory as the script
    drive = GoogleDrive(gauth)
    
    return drive

工作目录/Users/mypath/access_google_drive包含client_secrets.json，看起来像，

{"web":{"client_id":"xxx","project_id":"invoice-creation-290413","auth_uri":"https://accounts.google.com/o/oauth2/auth","token_uri":"https://oauth2.googleapis.com/token","auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs","client_secret":"xxx","redirect_uris":["http://localhost:8080/"],"javascript_origins":["http://localhost:8080"]}}

我将真实的client_id和client_secret替换为xxx.

问题

当浏览器（Safari 14.0）显示Gdrive api link wants to access your Google Account并单击Allow时，该过程似乎卡住了。

大约 20 秒后，显示以下错误，

Failed to find "code" in the query parameters of the redirect.
Try command-line authentication
Traceback (most recent call last):

  File "<ipython-input-36-792f41ab7318>", line 1, in <module>
    gauth.LocalWebserverAuth()

  File "/opt/anaconda3/lib/python3.7/site-packages/pydrive2/auth.py", line 125, in _decorated
    code = decoratee(self, *args, **kwargs)

  File "/opt/anaconda3/lib/python3.7/site-packages/pydrive2/auth.py", line 273, in LocalWebserverAuth
    raise AuthenticationError("No code found in redirect")

AuthenticationError: No code found in redirect

我该如何解决这个问题？

解决方案

我正在导入connect_google_drive_api()另一个脚本，比如 script x.py。

connect_google_drive_api()函数和x.py行都可以os.chdir('/Users/my/fol/ders/access_google_drive')将工作目录设置为所在的client_secrets.json位置。

使用以下代码，我实际上可以毫无问题地建立连接，

def connect_google_drive_api():
        
    # use Gdrive API to access Google Drive
    from pydrive2.auth import GoogleAuth
    from pydrive2.drive import GoogleDrive
    
    gauth = GoogleAuth()
    gauth.LocalWebserverAuth() # client_secrets.json need to be in the same directory as the script    
    
    drive = GoogleDrive(gauth)
    
    return drive
