How to invoke a service that uses handle_GET etc. programmatically

Hi,

I have services that are using handle_GET and handle_POST, now I want to call these services from another service with self.invoke(). When I look at the code for client.invoke() it does a self.session.post() call.

Does this mean the I cannot call the handle_GET() of another service using self.invoke() from my service?

Regards, Jan

Hello @jjmurre,

one needs to make the target service believe it’s being invoked through an HTTP channel with its WSGI environment so the code will look like below:

# -*- coding: utf-8 -*-
from __future__ import absolute_import, division, print_function, unicode_literals

from zato.server.service import Service

class MyService1(Service):
    name = 'my.service1'

    def handle_GET(self):
        self.response.payload = 'Hello'

class MyService2(Service):
    name = 'my.service2'

    def handle(self):
        response = self.invoke('my.service1', wsgi_environ={'REQUEST_METHOD':'GET'})
        self.logger.info('Response from handle_GET is `%s`', response)
