Getting Basecamp API Working with Python

I found , but it wasn’t working for me. I was always getting 400 Bad Request when using it. Chris Conover was able to get the following code working.

import urllib2
 
protocol = 'https://'
url = 'example.com'
command = '/projects.xml'
headers = {'Accept' : 'application/xml', 
'Content-type' : 'applications/xml'}
username = 'x'
password = 'y'
 
# Setup password stuff
passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, url, username, password)
authhandler = urllib2.HTTPBasicAuthHandler(passman)
opener = urllib2.build_opener(authhandler)
urllib2.install_opener(opener)
 
# Send the request and get response
req = urllib2.Request(protocol + url + command, None, headers)
response = urllib2.urlopen(req)
results = response.read()
 
print results

I thought it was a problem with how the authorization was formed so based on the above code I modified the old basecamp.py file and I was able to get a response. The following is what I changed.

Around line 64

    def __init__(self, username, password, protocol, url):
        self.baseURL = protocol+url
        if self.baseURL[-1] == '/':
            self.baseURL = self.baseURL[:-1]
 
        passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
        passman.add_password(None, url, username, password)
        authhandler = urllib2.HTTPBasicAuthHandler(passman)
 
        self.opener = urllib2.build_opener(authhandler)

And around line 142

path = '/projects.xml'

With that I was able to use basecamp.py to retrieve a list of projects. Other modifications may be needed for other features, but that was all I planned on using.

Here is an example of using to parse the XML response to get the names of all of the projects returned from basecamp.

import elementtree.ElementTree as ET
from basecamp import Basecamp
 
protocol = 'https://'
url = 'example.com'
username = 'x'
password = 'y'
 
bc = Basecamp(username, password, protocol, url)
projects = bc.projects()
tree = ET.fromstring(projects)
tags = tree.getiterator(tag='project')
 
for t in tags:
    project_name = t.findtext('name')
