You can download the source, or check out the darcs repository.
Questions to Tom.
To install the Python libraries, use distutils, as described at http://www.python.org/doc/current/inst/inst.html.
Here is a sample CGI script using the API:
#!/usr/bin/python
import sys
sys.path.append("/home/tom/Build/Python/Raven/src/")
import cgitb; cgitb.enable()
import metapaw.Raven.Handlers.CGI
import metapaw.Raven as Raven
UCam = Raven.Service('https://raven.cam.ac.uk/auth/authenticate.html',
{'2': '/home/tom/Incoming/Raven_test/Raven_keys/pubkey2'} )
def printBody(body):
print 'Content-Type: text/html'
print
print '<html><head><title>Raven Test</title></head><body>'
print body
print '<p><a href="?">Try Again</a></p></body></html>'
try:
cred = Raven.authenticate(UCam,
thisURL = 'http://localhost:8000/cgi-bin/Raven_test.cgi',
message = 'I do not know who you are',
targetDescription = "Tom's pyraven test",
pageParameters = 'These are my parameters: !"#$%^&*()',
# Default values
#reauthenticate = Raven.DontCare,
#maximumClockSkew = 300,
#ravenHandlesErrors = False
# Default is to accept any method
#allowedMethods = ('pwd', 'card'),
)
except Exception, e:
printBody("<p>Something went wrong: %s</p>" % repr(e)[1:-1])
raise
else:
printBody("<h1>This is my first Raven test</h1>" +
"<p>You are logged in as <span style='font-weight: bold'>%s</span>.</p>" % cred.principal +
"<p>The message from Raven was '%s'.</p>" % cred.message +
"<p>The page parameters were '%s'.</p>" % cred.pageParameters)
