在python中尝试使用gdata和oauth2时遇到麻烦

本文介绍了在python中尝试使用gdata和oauth2时遇到麻烦的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

晚上，我一直在尝试将我的博主python应用迁移到oauth2，因为旧的Clientlogin（）已被弃用和删除。
所以，我基本上是通过整个网页进行搜索，无法使我的应用程序正常工作。

这是使用测试的基本代码：

  FLOW = flow_from_clientsecrets（'/home/b/client_secret.json',scope='https://www.googleapis .com / auth / blogger'，message =Client Secrets Not Found）
 
 storage = Storage（'blogger.dat'）
 credentials = storage.get（）
 parser = argparse.ArgumentParser（parents = [tools.argparser]）
 flags = parser.parse_args（）
如果凭证为None或credentials.invalid：
 credentials = run_flow（FLOW，标志）
如果credentials.access_token_expired：
 credentials.refresh（httplib2.Http（））
 
 SCOPE ='https://www.blogger.com/feeds'
 
 token = gdata.gauth.OAuth2TokenFromCredentials（credentials）
 
 client = gdata.blogger.client.BloggerClient（）
 
 token.authorize（client）
 
 post = client.add_post（blog_id， title =blah，body =blah，labels =label，draft = False，title_type =xhtml，body_type =html）

我收到一个401错误代码，每次我尝试执行此操作都是未经授权的。

有人可以帮我吗？我真的很感激：）

问候语

解决方案

我已经解决了我的问题gdata.gauth：
我使用 auth2token = gdata.gauth.OAuth2Token（client_id，client_secret，scope，user_agent）

获得授权令后，我会生成一个授权网址以获取 auth2token.generate_authorize_url（redirect_uri = URL，approval_prompt =force）的访问代码。 code>

 
 
 一旦您获得此网址，您手动获取代码并生成刷新令牌，您可以通过该令牌生成访问令牌：
  token = auth2token.get_access_token（code）。足够容易有关如何将令牌保存到文件中的blob字符串的任何其他信息，请参阅：
  
 
Good evening, i've been trying to migrate my blogger python app to oauth2 since the good old Clientlogin() has been deprecated and erased.So, basically i searched through the entire web and couldn't manage to make my application to work correctly.
This is the basic code im using for testing:
FLOW =         flow_from_clientsecrets('/home/b/client_secret.json',scope='https://www.googleapis.com/auth/blogger',message="Client Secrets Not Found")

storage = Storage('blogger.dat')
credentials = storage.get()
parser = argparse.ArgumentParser(parents=[tools.argparser])
flags = parser.parse_args()
if credentials is None or credentials.invalid:
    credentials = run_flow(FLOW, storage, flags)
if credentials.access_token_expired:
    credentials.refresh(httplib2.Http())

SCOPE = 'https://www.blogger.com/feeds'

token = gdata.gauth.OAuth2TokenFromCredentials(credentials)

client = gdata.blogger.client.BloggerClient()

token.authorize(client)

post = client.add_post(blog_id, title="blah", body="blah",     labels="label", draft=False, title_type="xhtml", body_type="html")
I get a 401 error code, unauthorized everytime i try to do this.
Traceback (most recent call last):

    response, Unauthorized)

Can someone help me out with this? I'd really appreciate it :)

 解决方案 
Finally i've fixed my issue with gdata.gauth:I used auth2token = gdata.gauth.OAuth2Token(client_id,client_secret,scope,user_agent)
After getting the authorization token i generate an authorized url to get an access code with auth2token.generate_authorize_url(redirect_uri=URL,approval_prompt="force").
once you get this url, you manually get the code and generate a refresh token, with which you generate an access token:token = auth2token.get_access_token(code). Easy enough. For any other information as to how to save the token to a blob string in a file here's the reference:gdata-python-api + Analytics with simple auth
