Node JS Client never gets response from Python server

Hi,
I am trying to make a little program using a python server and a nodejs client.
Here is my server:
# =====================================
# Function
# =====================================
class CMpyBikesWrapper():
def get_all_networks(self):
schemas = map(lambda name: re.sub(r'\.json$', '', name), pybikes.get_all_data())
i = 0
networks = []
for schema in schemas:
for cname, instance in pybikes.get_instances(schema):
networks.append(instance)
return networks
# =====================================
# Server
# =====================================
s = zerorpc.Server(CMpyBikesWrapper())
s.bind("tcp://0.0.0.0:9000")
print("Listening on port 9000")
s.run()
And this is my client:
var zerorpc = require("zerorpc");
var client = new zerorpc.Client();
client.connect("tcp://127.0.0.1:9000");
client.invoke("get_all_networks", function(error, res, more) {
console.log(res);
callback(res);
});
client.close()
My problem is that the answer never comes back from the server. I know that my request gets to the server and that there is no error.
Is there anything wrong in my node JS client. It also works when I try with a terminal as client
zerorpc --client --connect tcp://127.0.0.1:9000 get_all_networks
Hi, what is callback
in your client?
My callback is a simple function for my API. But I think the problem is elsewhere because the console.log(res) does not log anything...
When i put a breakpoint on the console.log line it never stops.
function(err, result) {
if (err)
{
req.stats.error = err;
res.status(err.httpCode).json({error: err.error});
}
else
{
res.json(result);
}
next();
});
I suppose printing the error doesn't work either? Does the helloworld on http://www.zerorpc.io/ works? I am all out of ideas.
I just did a clean project with only the Hello World from your site.
And I got this error in my node JS Client
/usr/local/bin/node --debug-brk=59893 --nolazy app.js
