Authenticating to Jazz via Python

0
Kevin Murphy (96●2●13●17) | asked Oct 12 '11, 11:14 a.m.
All,

I'm trying to connect to Jazz via Python to do some OSLC testing. I found some old code here and have updated it a bit. I keep getting a 408 Server Timeout Error.

I'm wondering if anyone can give me some troubleshooting advice? Also, if I've posted to the wrong forum, please let me know.

Here's the code: 


import urllib

import httplib2

from xml.dom.minidom import parse, parseString

from exceptions import Exception





class JazzClient(object):

    def __init__(self, server_url, user, password):

        self.base_url = server_url

        self.jts_url = self.base_url + "/jts"

        self.ccm_url = self.base_url + "/ccm"

        self.qm_url = self.base_url + "/qm"

       

        self.http = httplib2.Http()

        self.http.disable_ssl_certificate_validation=True

        self.http.follow_redirects = True

        self.headers = {'Content-type': 'text/xml'}

       

        #1) before authentification one needs to go first to a "restricted resource"

        resp, content = self.http.request( self.ccm_url + "/oslc/workitems/1.xml", 'GET', headers=self.headers)

        #TODO sometimes returns capital X-

        #TODO check before if the key is in dictionary, if not something is wrong as well

        if resp['x-com-ibm-team-repository-web-auth-msg'] != 'authrequired':

            raise Exception("something is wrong seems the server doesn't expect authentication!")



           

        self.headers['Cookie']=  resp['set-cookie'] 

        self.headers['Content-type'] = 'application/x-www-form-urlencoded'

          

        #2 now we can start the authentication via j_security_check page

        resp, content = self.http.request(self.jts_url+'/j_security_check' , 'POST', headers=self.headers, 

                    body=urllib.urlencode({'j_username': user, 'j_password': password}))

              

        #TODO check auth worked fine, if not throw exception

        #if resp['x-com-ibm-team-repository-web-auth-msg'] != 'authrequired':

        self.resp = resp

        #    raise Exception("something is wrong...seems the server doesn't like our credentials!")

        

        #3 get the requested resource - finish the authentication

        resp, content = self.http.request( self.ccm_url + "/oslc/workitems/1.xml", 'GET', headers=self.headers)

Although this is an old question this was the first hit I found on the forum when searching for python and authentication. Therefore I thought I would provide an answer in case anyone else comes across it.

I have just been trying to authenticate to jazz via python, and and the only part missing from the original code is to save the new cookie which is returned after the authentication. This seemed to be a change when we moved from RTC 3.1 to RTC 4.0 (in RTC 3.1 the cookie was the same from the first call). 

#2 now we can start the authentication via j_security_check page

        resp, content = self.http.request(self.jts_url+'/j_security_check' , 'POST', headers=self.headers, body=urllib.urlencode({'j_username': user, 'j_password': password}))

self.headers['Cookie']=  resp['set-cookie']  # Save the new cookie returned here

#3 get the requested resource - finish the authentication
        resp, content = self.http.request( self.ccm_url + "/oslc/workitems/1.xml", 'GET', headers=self.headers)

You'll notice that the curl command in another answer saves the cookie in both cases (using -b %COOKIES%) .

Hope this helps. Regards, Colin.

That did the trick for me.  Seems to work fine for me now.  I am using this to access an RTC server with Python, and I get data back the way that I would expect.

Hi Kevin,  Total shot in the dark on responding to this, but did you ever resolve your issue?  I am currently trying to do the same thing and am also running into 408 responses from my RQM server.

I don't know python, but here is a short curl batch file that may help

<code>
set COOKIES=.\cookies.txt

set USER=
set PASSWORD=
set HOST=https://localhost:9743


curl -k -c %cookies% "%host%/jts/authenticated/identity"

curl -k -L -b %COOKIES% -c %COOKIES% -d j_username=%USER% -d j_password=%PASSWORD% "%host%/jts/authenticated/j_security_check"

curl -k -L -b %COOKIES% "%host%/ccm/oslc/workitems/catalog
</code>
