Are there any OpenID tutorials?

[Peter Robinett]

Hi all,

I'd like to add OpenID logins to my Lift app and would love a tutorial
about how to do so. I assume I mix OpenIDProtoUser into my User model,
but I don't know what to do beyond that. Can anyone point me in the
right direction?

Thanks!

Peter

PS This would make a great Wiki article.

We use OpenID in ESME although we don't use any "*ProtoUser"

Maybe, you can get some pointers there.

Take a look here:
http://svn.apache.org/viewvc/incubator/esme/trunk/server/src/main/scala/org/apache/esme/model/User.scala?view=markup

Indeed. I have a blog post waiting for this (I know, lots of promises :-)

But here's a sample that should work:

object MyVendor extends SimpleOpenIDVendor {
def ext(di:DiscoveryInformation, authReq: AuthRequest): Unit = {
import WellKnownAttributes._
WellKnownEndpoints.findEndpoint(di) map {ep => ep.makeAttrExtension(List(Email, FullName, FirstName, LastName)) foreach {ex => authReq.addExtension(ex)}}
}

override def createAConsumer = new OpenIDConsumer[UserType] {
beforeAuth = Full(ext _)
}
}

object User extends User with MetaOpenIDProtoUser[User] with FancyKeyedMetaMapper[Long,User] with FancyCRUDify[Long,User] {
def openIDVendor = MyVendor
override def screenWrap = Full(<lift:surround with="default" at="content"><lift:bind /></lift:surround>)
override def dbTableName = "users"
override def homePage = if (loggedIn_?) "/dashboard" else "/"

}

class User extends OpenIDProtoUser[User] {
def getSingleton = User
}

And then in Boot

LiftRules.dispatch.append(model.MyVendor.dispatchPF)
LiftRules.snippets.append(model.MyVendor.snippetPF)

Thanks. I haven't tested it myself yet, but I went ahead and threw up
a wiki page anyway:

Jeppe, you wouldn't happened to have tried to use it with SBT, would
you?

I'm using the following lines in my SBT project declaration:
val lift = "net.liftweb" % "lift-mapper" % "2.0-SNAPSHOT" % "compile"
val liftOpenID = "net.liftweb" % "lift-openid" % "2.0-SNAPSHOT" %
"compile"

Unfortunately, when I try to import net.liftweb.openid._, I'm told it
doesn't exist. Anyone able to hazard a guess?

Thanks,
Peter

Sounds like you haven't called update from the sbt console

Actually it turns out I hadn't called reload before calling update.
Sorry to pollute the list!

No list pollution from my perspective.  There'll be 100 people that hit this same issue as sbt becomes a (rightfully) more popular way to do Lift coding.  Getting used to the frequently hit stumbling blocks will help us help people.

Hey Jeppe, I'm only trying to use your example now and am having some
problems. While I figured out where to import DiscoveryInformation and
AuthRequest and that ep.makeAttrExtension should be
ep.makeAttributeExtension (I created ticket #488 for myself to update
the ScalaDocs), I now get an exception when I try to login after
entering my OpenID URL:
java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

Is this a missing dependency in lift-openid or have I missed a logging
setup step in my Boot.scala?

Thanks,
Peter

This is because "something" depends on commons-logging (which should be
avoided like the plague if you ask me :-). SLF4J has a wrapper that you
can add which tunnels requests to CL through to your chosen SLF4j
logging system. It's called jcl-over-slf4j.jar.

I thought I'd made this dependency exclusion in the poms, but either I
didn't or it doesn't work. If you create a ticket for this I'll look
into it. In the meantime you should be able to continue by adding
jcl-over-slf4j as dependency....

Thanks, Jeppe. Here's the ticket:
