使用urllib2和python以及JIRA REST API进行基本身份验证 [英] Basic authentication using urllib2 with python with JIRA REST api

问题描述

我正在尝试找到如何在python中使用urllib2使用基本身份验证来获取问题KEY JIRA REST API 描述了URI可用

I am trying to find how i can use basic authentication using urllib2 in python to get the issue KEY The JIRA REST API describes the URI's available

感谢大家的支持，我将尝试一下，与此同时，我只是想用自己的努力来更新它:这是我尝试过的示例python代码:

Thanks for the sugestions, i will try it, meanwhile, i just wanted to update this with my own effort: Here is the sample python code i tried:

import urllib2, sys, re, base64
from urlparse import urlparse
theurl = 'http://my.rest-server.com:8080/rest/api/latest/AA-120'            # if you want to run this example you'll need to supply a protected page with y
our username and password
username = 'username'
password = 'password'            # a very bad password

req = urllib2.Request(theurl)
print req
try:
    handle = urllib2.urlopen(req)
    print handle
except IOError, e:                  # here we are assuming we fail
    pass
else:                               # If we don't fail then the page isn't protected
    print "This page isn't protected by authentication."
    sys.exit(1)
if not hasattr(e, 'code') or e.code != 401:                 # we got an error - but not a 401 error
    print "This page isn't protected by authentication."
    print 'But we failed for another reason.'
    sys.exit(1)

authline = e.headers.get('www-authenticate', '')                # this gets the www-authenticat line from the headers - which has the authentication
 scheme and realm in it
if not authline:
    print 'A 401 error without an authentication response header - very weird.'
    sys.exit(1)
authobj = re.compile(r'''(?:\s*www-authenticate\s*:)?\s*(\w*)\s+realm=['"](\w+)['"]''', re.IGNORECASE)          # this regular expression is used to
 extract scheme and realm
matchobj = authobj.match(authline)
if not matchobj:                                        # if the authline isn't matched by the regular expression then something is wrong
    print 'The authentication line is badly formed.'
    sys.exit(1)
scheme = matchobj.group(1)
print scheme
realm = matchobj.group(2)
print realm
if scheme.lower() != 'basic':
    print 'This example only works with BASIC authentication.'
    sys.exit(1)

base64string = base64.encodestring('%s:%s' % (username, password))[:-1]
authheader =  "Basic %s" % base64string
req.add_header("Authorization", authheader)
try:
    handle = urllib2.urlopen(req)
except IOError, e:                  # here we shouldn't fail if the username/password is right
    print "It looks like the username or password is wrong."
    sys.exit(1)
thepage = handle.read()
server = urlparse(theurl)[1].lower()            # server names are case insensitive, so we will convert to lower case
test = server.find(':')
if test != -1: server = server[:test]           # remove the :port information if present, we're working on the principle that realm names per serve
r are likely to be unique...

passdict = {(server, realm) : authheader }      # now if we get another 401 we can test for an entry in passdict before having to ask the user for a
 username/password

print 'Done successfully - information now stored in passdict.'
print 'The webpage is stored in thepage.'

---我得到结果: 此页面不受身份验证保护. 但是我们由于另一个原因失败了.

--- and i get the result: This page isn't protected by authentication. But we failed for another reason.

页面受身份验证保护

我尝试安装请求，但出现错误:

有趣的是，我昨天正在为 JIRA Python CLI .我采用了使用REST API的方法来获取身份验证cookie和自定义打开器.下面的示例显示了使用打开器将数据发布到页面上以添加组件，但是您可以替换该组件 并针对其他REST调用调用正确的URL.

Funny, I was working on this yesterday for the JIRA Python CLI. I took the approach of using the REST API to get an authentication cookie and a custom opener. The example below shows using the opener to post data to a page to add a component, but you could replace that with a call to the correct URL for a different REST call.

import urllib
import urllib2
import cookielib

jira_serverurl = "http://jira.example.com:8080"
creds = { "username" : "admin", "password" : "admin" }
authurl = jira_serverurl + "/rest/auth/latest/session"

# Get the authentication cookie using the REST API
cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
req = urllib2.Request(authurl)
req.add_data('{ "username" : "admin", "password" : "admin" }')
req.add_header("Content-type", "application/json")
req.add_header("Accept", "application/json")
fp = opener.open(req)
fp.close()

add_component_url = jira_serverurl + "/secure/project/AddComponent.jspa?pid=10020&name=ABC4"
print "Using %s" % (add_component_url)

# Have to add data to make urllib2 send a POST
values = {}
data = urllib.urlencode(values)

# Have to tell JIRA to not use a form token
headers = {'X-Atlassian-Token': 'no-check'}

request = urllib2.Request(add_component_url, data, headers=headers)
fp = opener.open(request)

print fp.read()
