我已经尝试了一切我能找到的方法来让它发挥作用......
我正在为基于 python 的任务程序（称为 GTG）开发一个插件。我在 Opensuse Linux 上运行 Gnome。
代码（Python 2.7）：
def initialize(self):
"""
Intialize backend: try to authenticate. If it fails, request an authorization.
"""
super(Backend, self).initialize()
path = os.path.join(CoreConfig().get_data_dir(), 'backends/gtask', 'storage_file-%s' % self.get_id())
# Try to create leading directories that path
path_dir = os.path.dirname(path)
if not os.path.isdir(path_dir):
os.makedirs(path_dir)
self.storage = Storage(path)
self.authenticate()
def authenticate(self):
""" Try to authenticate by already existing credences or request an authorization """
self.authenticated = False
credentials = self.storage.get()
if credentials is None or credentials.invalid == True:
self.request_authorization()
else:
self.apply_credentials(credentials)
# Request periodic import, avoid waiting a long time
# self.start_get_tasks()
def apply_credentials(self, credentials):
""" Finish authentication or request for an authorization by applying the credentials """
http = httplib2.Http(ca_certs = '/etc/ssl/certs/ca_certs.pem', disable_ssl_certificate_validation=True)
http = credentials.authorize(http)
# Build a service object for interacting with the API.
self.service = build_service(serviceName='tasks', version='v1', http=http, developerKey='AIzaSyAmUlk8_iv-rYDEcJ2NyeC_KVPNkrsGcqU')
# self.service = build_service(serviceName='tasks', version='v1')
self.authenticated = True
def _authorization_step2(self, code):
credentials = self.flow.step2_exchange(code)
# credential = self.flow.step2_exchange(code)
self.storage.put(credentials)
credentials.set_store(self.storage)
return credentials
def request_authorization(self):
""" Make the first step of authorization and open URL for allowing the access """
self.flow = OAuth2WebServerFlow(client_id=self.CLIENT_ID,
client_secret=self.CLIENT_SECRET,
scope='https://www.googleapis.com/auth/tasks',
redirect_uri='http://localhost:8080',
user_agent='GTG')
oauth_callback = 'oob'
auth_uri = self.flow.step1_get_authorize_url(oauth_callback)
# credentials = self.flow.step2_exchange(code)
# url = self.flow.step1_get_authorize_url(oauth_callback)
browser_thread = threading.Thread(target=lambda: webbrowser.open_new(auth_uri))
browser_thread.daemon = True
browser_thread.start()
# Request the code from user
BackendSignals().interaction_requested(self.get_id(), _(
"You need to <b>authorize GTG</b> to access your tasks on <b>Google</b>.\n"
"<b>Check your browser</b>, and follow the steps there.\n"
"When you are done, press 'Continue'."),
BackendSignals().INTERACTION_TEXT,
"on_authentication_step")
def on_authentication_step(self, step_type="", code=""):
if step_type == "get_ui_dialog_text":
return _("Code request"), _("Paste the code Google has given you"
"here")
elif step_type == "set_text":
try:
credentials = self._authorization_step2(code)
except FlowExchangeError, e:
# Show an error to user and end
self.quit(disable = True)
BackendSignals().backend_failed(self.get_id(),
BackendSignals.ERRNO_AUTHENTICATION)
return
self.apply_credentials(credentials)
# Request periodic import, avoid waiting a long time
self.start_get_tasks()
浏览器窗口打开，我看到来自 Google 的代码。该程序会打开一个小窗口，我可以在其中输入来自 Google 的代码。当发生这种情况时，我会在控制台中看到以下内容：
No handlers could be found for logger "oauth2client.util"
Created new window in existing browser session.
[522:549:0108/063825:ERROR:nss_util.cc(821)] After loading Root Certs, loaded==false: NSS error code: -8018
但 Chrome 中的 SSL 图标是绿色的...
然后当我提交代码时，我得到：

我已尝试按照此处所述导入证书：如何更新Github的httplib2的cacerts.txt？ https://stackoverflow.com/questions/18557744/how-to-update-cacerts-txt-of-httplib2-for-github
我曾尝试禁用验证（httplib2.Http(disable_ssl_certificate_validation=True)），如网络上所述，
我已经更新了 python 包（这似乎让事情变得更糟）
我已在 /etc/ssl... 和 /usr/lib/python2.7/... 之间来回复制 ca_certs.pem
当我在浏览器中访问身份验证页面时，它说证书已验证...
我还可以检查什么？
简短的测试代码：
from oauth2client.client import OAuth2WebServerFlow
from oauth2client.tools import run
from oauth2client.file import Storage
CLIENT_ID = 'id'
CLIENT_SECRET = 'secret'
flow = OAuth2WebServerFlow(client_id=CLIENT_ID,
client_secret=CLIENT_SECRET,
scope='https://www.googleapis.com/auth/tasks',
redirect_uri='http://localhost:8080')
storage = Storage('creds.data')
credentials = run(flow, storage)
print "access_token: %s" % credentials.access_token
