我厌倦了将request-oauth库（基于python-request）移植到Python 3（在2to3的帮助下），但我有问题需要使用StatusNet（与Twitter相同的API）验证签名。OAuth身份验证，无效签名
当我向oauth/request_token发出请求时，我没有问题，但是要到oauth/access_token我有一个错误401 Invalid signature。我不明白为什么，因为在我看来，我签署的是正确的。
例如，与蟒蛇2码，CF hook.py和auth.py（原从混帐回购协议），我得到：
signing_key = '0de1456373dfc9349dd38a48e61fc844&136d6b9a597ee57d4338254812681acd',
signing_raw = 'POST&http%3A%2F%2Fstatus2.dotzero.me%2Fapi%2Foauth%2Faccess_token&oauth_consumer_key%3Dec3ad931b294b51a5ff595c732acb7a5%26oauth_nonce%3D33448267%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1332279747%26oauth_token%3D2131043f3516bcb730d391ed2033a880%26oauth_verifier%3D8816492%26oauth_version%3D1.0'
oauth_hook.token.key = '2131043f3516bcb730d391ed2033a880'
oauth_hook.token.secret = '136d6b9a597ee57d4338254812681acd'
request.data_and_params = {'oauth_version': '1.0', 'oauth_signature': 'xyjxH5QcfZXnG111L7qANZ+ahRI=',
'oauth_token': '2131043f3516bcb730d391ed2033a880', 'oauth_nonce': '33448267',
'oauth_timestamp': '1332279747', 'oauth_verifier': '8816492',
'oauth_consumer_key': 'ec3ad931b294b51a5ff595c732acb7a5',
'oauth_signature_method': 'HMAC-SHA1'}
，并与我的Python 3端口，CF hook.py和auth.py，我得到：
signing_key = '0de1456373dfc9349dd38a48e61fc844&136d6b9a597ee57d4338254812681acd',
signing_raw = 'POST&http%3A%2F%2Fstatus2.dotzero.me%2Fapi%2Foauth%2Faccess_token&oauth_consumer_key%3Dec3ad931b294b51a5ff595c732acb7a5%26oauth_nonce%3D52360702%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1332278837%26oauth_token%3D2131043f3516bcb730d391ed2033a880%26oauth_verifier%3D8816492%26oauth_verifier%3D8816492%26oauth_version%3D1.0'
oauth_hook.token.key = '2131043f3516bcb730d391ed2033a880'
oauth_hook.token.secret = '136d6b9a597ee57d4338254812681acd'
request.data_and_params = {'oauth_nonce': '52360702', 'oauth_timestamp': '1332278837',
'oauth_verifier': '8816492', 'oauth_consumer_key': 'ec3ad931b294b51a5ff595c732acb7a5',
'oauth_signature_method': 'HMAC-SHA1', 'oauth_version': '1.0',
'oauth_token': '2131043f3516bcb730d391ed2033a880',
'oauth_signature': 'BRsb11dk++405uaq5pRS+CMUzbo='}
这两个对我来说都不错，但第一个成功，第二个返回401错误，签名无效。
在这两种情况下，我得到的token.key和token.secret作为的结果：
OAuthHook.consumer_key = self.ckey
OAuthHook.consumer_secret = self.csecret
oauth_hook = OAuthHook()
client = requests.session(hooks={'pre_request': oauth_hook})
response = client.post('%soauth/request_token' % (self.url), {'oauth_callback': 'oob'})
# new oauth_hook with the request token
oauth_hook = OAuthHook(response[b'oauth_token'][0],response[b'oauth_token_secret'][0])
他们，我去oauth/authorize?oauth_token=%s" % oauth_hook.token.key获得授权的应用程序，并获得pin码。从那以后，我可以从auth.py文件做有问题的请求
...
response = client.post('%soauth/request_token' % (self.url), {'oauth_callback': 'oob'})
oauth_hook = OAuthHook(response[b'oauth_token'][0],response[b'oauth_token_secret'][0])
# get the pincode from %soauth/authorize?oauth_token=%s" % (self.url, oauth_hook.token.key)
oauth_hook.token.set_verifier(pincode)
client = requests.session(hooks={'pre_request': oauth_hook})
response = client.post("%soauth/access_token" % (self.url),
{'oauth_verifier': pincode})
签名代码是
def sign(self, request, consumer, token):
"""Builds the base signature string."""
key, raw = self.signing_base(request, consumer, token)
hashed = hmac.new(key.encode(), raw.encode(), sha1)
# Calculate the digest base 64.
return binascii.b2a_base64(hashed.digest())[:-1]
任何想法，为什么它不与py3k代码工作？
谢谢
