我有相同一段編碼處理Twitter用戶流運行在兩臺不同的機器。這兩款機器都是使用python 2.6.5的Ubuntu Lucid，但在我家的機器上，我收到了HTTP Error 401: Unauthorized，而在大學時，它完美地工作。在兩臺機器上，當我使用curl和相同的參數（即消費者密鑰，消費者機密，訪問令牌和訪問密鑰）時，它完美地工作。在Python中使用OAuth的Twitter流在兩臺同等配置的機器上表現不同
看到代碼波紋管，它是由Josh Sharp
from oauth.oauth import OAuthRequest, OAuthSignatureMethod_HMAC_SHA1
from hashlib import md5
import json, time
import random, math, re, urllib, urllib2
STREAM_URL = "https://userstream.twitter.com/2/user.json"
class Token(object):
def __init__(self,key,secret):
self.key = key
self.secret = secret
def _generate_nonce(self):
random_number = ''.join(str(random.randint(0, 9)) for i in range(40))
m = md5(str(time.time()) + str(random_number))
return m.hexdigest()
CONSUMER_KEY = 'consumer_key'
CONSUMER_SECRET = 'consumer_secret'
ACCESS_TOKEN = 'token'
ACCESS_TOKEN_SECRET = 'token_secret'
access_token = Token(ACCESS_TOKEN,ACCESS_TOKEN_SECRET)
consumer = Token(CONSUMER_KEY,CONSUMER_SECRET)
parameters = {
'oauth_consumer_key': CONSUMER_KEY,
'oauth_token': access_token.key,
'oauth_signature_method': 'HMAC-SHA1',
'oauth_timestamp': str(int(time.time())),
'oauth_nonce': access_token._generate_nonce(),
'oauth_version': '1.0',
}
oauth_request = OAuthRequest.from_token_and_callback(access_token,
http_url=STREAM_URL,
parameters=parameters)
signature_method = OAuthSignatureMethod_HMAC_SHA1()
signature = signature_method.build_signature(oauth_request, consumer, access_token)
parameters['oauth_signature'] = signature
data = urllib.urlencode(parameters)
req = urllib2.urlopen("%s?%s" % (STREAM_URL,data))
buffer = ''
# We're using urllib2 to avoid external dependencies
# even though pyCurl actually handles the callbacks
# much more gracefully than this clumsy method.
# We read a byte at a time until we find a newline
# which indicates the end of a chunk.
while True:
chunk = req.read(1)
if not chunk:
print buffer
break
chunk = unicode(chunk)
buffer += chunk
tweets = buffer.split("\n",1)
if len(tweets) > 1:
print tweets[0]
buffer = tweets[1]
誤差產生時，我嘗試在國內執行的是：
File "py_stream.py", line 48, in <module>
req = urllib2.urlopen("%s?%s" % (STREAM_URL,data))
File "/usr/lib/python2.6/urllib2.py", line 126, in urlopen
return _opener.open(url, data, timeout)
File "/usr/lib/python2.6/urllib2.py", line 397, in open
response = meth(req, response)
File "/usr/lib/python2.6/urllib2.py", line 510, in http_response
'http', request, response, code, msg, hdrs)
File "/usr/lib/python2.6/urllib2.py", line 435, in error
return self._call_chain(*args)
File "/usr/lib/python2.6/urllib2.py", line 369, in _call_chain
result = func(*args)
File "/usr/lib/python2.6/urllib2.py", line 518, in http_error_default
raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 401: Unauthorized
由於它的工作原理用在兩臺機器上嫋嫋，我想沒有什麼是與SSL認證有關的錯誤。但同時它讓我想知道當我在家中使用它時會發生什麼失敗。
