I'm using web2py 1.65.5 with google app engine.
I've run into a problem with request.args in relation to my json
calls:
@service.json
def json_read_nologin():
return request.args[0]
or the same function defined sans the service decorator, both work
fine, as long as I don't pass something containing an @ sign, i.e.
http://localhost:8000/init/default/json_read_nologin/[email protected]
this generates an invalid request even if url encoded:
http://localhost:8000/init/default/json_read_nologin/user%40domain.com
I'm not sure what I'm doing wrong here but this behavior doesn't seem
like what I'd expect.
Thanks,
David
