XMLRPG?

[casimirian]

Was there a reason GET is disabled for https://www.dreamwidth.org/interface/xmlrpc?

To answer the specific question, I don't remember.

I don't think the API does anything with GET requests thought? I feel like POST is the only thing we'd want to support?

Thanks, Mark.

I don't think POST is the only thing we would want to support.

I believe GET also receives user data, such as groups user has access to.

I don't completely understand the functionality of XMLRPC, so I'll describe the problems I've experienced.

1. My ljl client receives a server error when trying to POST.
2. A similar problem occurs with https://github.com/daniilr/python-lj
3. python-lj queries against Dreamwidth's XMLRPC.
4. When going to XMLRPC on the dreamwidth.org domain, you receive an error. LJ's domain does not have this problem.

some documentation on how xmlrpc works

GET can only be used for idempotent things that don't change any state, and I don't believe there is anything in our API that is really idempotent + doesn't change state?

Anyway, moot point since it sounds like you're also having problems with third party clients trying to do POST requests. I did some investigation and it looks like the problem is that the `python-lj` library is using insecure HTTP which is explicitly no longer supported. Someone will have to fix that.

So, I don't believe that not supporting GET has anything to do with the problem here, it's just a broken client not accessing the secured HTTPS endpoint correctly.

Ah, ok. I'll try updating the client.

Thank you.

Kind of a "from the mists of time" thing, but just in case anyone else using the lj lib at https://github.com/daniilr/python-lj finds this:

For DW, just subclass LJServer and create DWTransport to use xmlrpclib.SafeTransport instead of xmlrpclib.Transport. (Or don't bother and just straight use xmlrpclib.SafeTransport, sure, whatever:P)

try:
    import xmlrpc.client as xmlrpclib
except ImportError:
    import xmlrpclib
try:
    import urllib.request as urllib2
except ImportError:
    import urllib2


from lj import lj


class DWTransport(xmlrpclib.SafeTransport):
    pass


class DWServer(lj.LJServer):
    def __init__(self, clientversion, user_agent, host='https://www.dreamwidth.org/'):
        super().__init__(clientversion, user_agent, host)
        transport = DWTransport()
        transport.user_agent = user_agent
        self.server = xmlrpclib.ServerProxy(host + 'interface/xmlrpc', transport)

dreamwidth = DWServer("Python-Blog3/1.0", "http://yoursite.com; your@email.com")
dreamwidth.login(username, password)
response = dreamwidth.postevent(subject, message)

Wow, you're the best. Thank you.

Oh cool - I’m glad it was helpful! Thank you for raising this in the first place so I had somewhere to start :D

Posting only to say that the idea of an XML role-playing game is twisted, meaning I am vaguely interested. :P
