Question

我在google中的oauth2-Authorization存在问题，尤其是第2步：将代码交换为访问令牌。这是我的代码：

import httplib2   
from oauth2client.client import OAuth2WebServerFlow
from oauth2client.file import Storage
from apiclient.discovery import build
import simplejson as json
import cgi
...
#initiating the flow
flow = OAuth2WebServerFlow(client_id='<client_id>',
                       client_secret='<client_secret>',
                       scope='https://www.googleapis.com/auth/drive',
                       redirect_uri='<url_to_this_script')

#initiating storing
storage = Storage('credentials_store.dat')
credentials = storage.get()

#checks, if there is a code already transmitted
if form.has_key("code"):
        code = form["code"].value
        #step 2: if so, then try to get credentials with the code
        #HERE IS THE PROBLEM
        credentials = flow.step2_exchange(code)
        storage.put(credentials)

if credentials is None or credentials.invalid:
        #step 1: get the code
        auth_uri = flow.step1_get_authorize_url()
        print "Location:%s" % auth_uri
        print # to end the CGI response headers.

所以我试着解释一下：

如果没有＆＃34;代码＆＃34;在参数中，当调用脚本时，将传递第一个if-then-else-check并且程序从步骤1开始。这部分没问题。用户将被重定向到他可以授权脚本的页面。
授权后将再次调用该脚本，但这次使用＆＃34;代码＆＃34;在参数中。如谷歌开发人员参考中所述，我尝试使用此命令获取凭据

凭据= flow.step2_exchange（代码）

在此步骤之前它工作正常但随后它会停止并显示错误消息：

oauth2client.client.FlowExchangeError: invalid_request

我做错了什么？谢谢你的帮助！

P.S。：如果您对此感兴趣，该应用程序只需访问我自己在google驱动器中的文档。

编辑：以下是完整的错误消息：
