2小时后Google Drive Python API可恢复上传错误401

首先,如果这是一个太愚蠢的问题,我很抱歉…这是我第一次尝试使用此脚本中涉及的任何技术(Python,驱动器api,oauth 2.0等).我发誓,在发布问题之前,我一直在寻找和试用这个约一个星期.呵呵呵

我正在尝试使用google-api-python-client上传一个仅在终端上的Linux Debian上的大文件(3.5GiB).我上传小文件时取得了一些成功,但是当我尝试上传大文件时,上传会在HTTP 401错误(未授权)启动后大约1~2小时停止.我一直在寻找如何获得新的访问令牌,但收效甚微.

到目前为止,这是我的(更新的)代码：

#!/usr/bin/python

import httplib2
import pprint
import time

from apiclient.discovery import build
from apiclient.http import MediaFileUpload
from apiclient import errors
from oauth2client.client import OAuth2WebServerFlow

# Copy your credentials from the APIs Console
CLIENT_ID = 'myclientid'
CLIENT_SECRET = 'myclientsecret'

# Check https://developers.google.com/drive/scopes for all available scopes
OAUTH_SCOPE = 'https://www.googleapis.com/auth/drive'

# Redirect URI for installed apps
REDIRECT_URI = 'urn:ietf:wg:oauth:2.0:oob'

# Run through the OAuth flow and retrieve credentials
flow = OAuth2WebServerFlow(CLIENT_ID, CLIENT_SECRET, OAUTH_SCOPE, REDIRECT_URI)
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()
credentials = flow.step2_exchange(code)

# Create an httplib2.Http object and authorize it with our credentials
http = httplib2.Http()
http = credentials.authorize(http)

drive_service = build('drive', 'v2', http=http)

# Insert a file
media_body = MediaFileUpload('bigfile.zip', mimetype='application/octet-stream', chunksize=1024*256, resumable=True)
body = {
    'title': 'bigfile.zip',
    'description': 'Big File',
    'mimeType': 'application/octet-stream'
}

retries = 0
request = drive_service.files().insert(body=body, media_body=media_body)
response = None
while response is None:
    try:
            print http.request.credentials.access_token
            status, response = request.next_chunk()
            if status:
                    print "Uploaded %.2f%%" % (status.progress() * 100)
                    retries = 0
    except errors.HttpError, e:
            if e.resp.status == 404:
                    print "Error 404! Aborting."
                    exit()
            else:   
                    if retries > 10:
                            print "Retries limit exceeded! Aborting."
                            exit()
                    else:   
                            retries += 1
                            time.sleep(2**retries)
                            print "Error (%d)... retrying." % e.resp.status
                            continue
print "Upload Complete!"

经过一番挖掘后,我发现授权的http对象在收到401后会自动刷新访问令牌.虽然它确实改变了访问令牌,但它仍然没有按预期继续上传…请参阅下面的输出：

我正在使用安装了Python 2.5.2的debian lenny,并在一周前通过pip install安装了ssl和google-api-python-client.

在此先感谢您的帮助.

编辑：显然,问题不在于api.我尝试了上面相同的代码,但有两个小文件,它们之间有1h(system.sleep()).输出是：

对于第二次上载,成功使用了新的访问令牌.那么,也许可恢复会话在一段时间后到期或者仅对该特定访问令牌有效？

解决方法:

我提交了一个issue on the google-api-python-client project,根据Google的Joe Gregorio的说法,问题在于后端：

“这是后端的问题,而不是API或您的代码.正如您推断的那样,如果上传时间太长,则access_token到期,此时无法继续恢复上传.现在解决这个问题,一旦在服务器端修复了问题,我将更新此错误.“
