I've reviewed my code while typing this reply and found that one of
the libraries I've been trying to use does in fact allow me to connect
(I wasn't using it correctly). I'll post the code for others to
benefit.
My controller (MyData.py) is as in the documentation:
from gluon.tools import Service
service = Service(globals())
def call():
return service()
@service.jsonrpc
def myfunction(a, b):
return a + b
Calling the following url without sending a json object (e.g. browser
window) returns a web2py "ValueError: No JSON object could be decoded"
error which I assume means that the controller is working correctly:
http://127.0.0.1:8000/MyApp/MyData/call/jsonrpc/myfunction
I've tried connecting from a client page using jQuery RPC:
http://plugins.jquery.com/project/rpc
I still can't get it to work.
I'm successful using the json-xml-rpc lib:
http://code.google.com/p/json-xml-rpc/
The following code works well.
var service = new rpc.ServiceProxy("/MyApp/MyData/call/jsonrpc", {
asynchronous: false,
protocol: "JSON-RPC",
sanitize: false,
methods: ['myfunction']
});
if(service.myfunction(4,5) == 9)
alert("Success!");
Thanks again!
