使用 Python 的 HTTPBasicAuthHandler 进行 Bitbucket API 身份验证
我正在尝试使用 bitbucket 的 API 获取私有存储库上的问题列表。
I have confirmed that HTTP Basic authentication works with hurl, but I am unable to authenticate in Python.改编此 教程 中的代码,我编写了以下脚本。
import cookielib
import urllib2
class API():
api_url = 'http://api.bitbucket.org/1.0/'
def __init__(self, username, password):
self._opener = self._create_opener(username, password)
def _create_opener(self, username, password):
cj = cookielib.LWPCookieJar()
cookie_handler = urllib2.HTTPCookieProcessor(cj)
password_manager = urllib2.HTTPPasswordMgrWithDefaultRealm()
password_manager.add_password(None, self.api_url, username, password)
auth_handler = urllib2.HTTPBasicAuthHandler(password_manager)
opener = urllib2.build_opener(cookie_handler, auth_handler)
return opener
def get_issues(self, username, repository):
query_url = self.api_url + 'repositories/%s/%s/issues/' % (username, repository)
try:
handler = self._opener.open(query_url)
except urllib2.HTTPError, e:
print e.headers
raise e
return handler.read()
api = API(username='my_username', password='XXXXXXXX')
api.get_issues('my_username', 'my_repository')
结果:
>>>
Server: nginx/0.7.62

Connection: close
Vary: Authorization,Cookie

Traceback (most recent call last):
File "C:/USERS/personal/bitbucket-burndown/bitbucket-api.py", line 29, in <module>
print api.get_issues('my_username', 'my_repository')
File "C:/USERS/personal/bitbucket-burndown/bitbucket-api.py", line 25, in get_issues
raise e
HTTPError: HTTP Error 401: UNAUTHORIZED
api.get_issues('jespern', 'bitbucket')
工作起来就像一个魅力。
我的代码有什么问题吗?

HTTPBasicAuthHandler 似乎存在问题。这有效:
It looks like there is an issue with HTTPBasicAuthHandler. This works:
我认为 Python 的 HTTPBasicAuthHandler 中没有错误。基本身份验证通常遵循以下过程:
对于 BitBucket,会发生这种情况:
BitBucket 从不发出 401,因此 Python 从不发送凭据。
查看此示例,以在不使用 cookie 的情况下使用 BitBucket 进行身份验证:
I don't think there's an error in Python's HTTPBasicAuthHandler. Basic authentication usually follows this process:
In the case of BitBucket, this happens:
BitBucket never issues the 401, so Python never sends the credentials.
Have a look at this example for authenticating with BitBucket without using cookies:
看一下python-bitbucket,它是 Bitbucket API 的 python 包装器。 原始库仅包含读取访问权限,但ericof 包括身份验证和一些写入访问权限,我已将其引入并在此基础上构建:https://bitbucket.org/bkmontgomery/python-bitbucket
您可以从私人存储库中检索问题,如下所示:
Take a look at python-bitbucket, which is a python wrapper for Bitbucket's API. The original library only includes read access, but ericof included authentication and some write access, which I've pulled in and built upon here: https://bitbucket.org/bkmontgomery/python-bitbucket
You could retrieve Issues from a private repo as follows:
您可以尝试对 HTTPPasswordMgr 进行子类化并重写 find_user_password() 方法,以查看代码在何处放弃查找密码。我的猜测是 add_password() 并没有完全按照您的预期进行。
You could try sub-classing HTTPPasswordMgr and overriding the find_user_password() method to see where your code is giving up on finding the password. My guess is that add_password() isn't doing exactly what you'd expect.
