use socket as client only

[scalpovich]

Hi Juks, I want to know if i neeed some custom thingd to use SQ as client rather than host in order to connect to another ISO host Or send an iso message through SQ from http client to an ISO host. In this case, SQ will be serve as SWITCH

Hi!

No you do not need any custom thing. The client part is already implemented into the application.

Hi juks Thank you for your feedback I want to use SQ as client to connect to an iso host with fix header (length + fixheader +message) To résume the host target has some specifications like : Send sign on to host each first connections and after that others logics (key exchange and that part has been done by customizing some code in SQ in isopacket and logics / packager Now the issue is about received iso message from host SQ say faulty invalid message in red

Hi!

The common message restrictions are defined here: https://github.com/juks/SocketQueue/blob/653ad6e888ebf6fb90399eaa4e8a216e103cbfda/lib/iso8583/lib/packager/smartVista.js#L24

And the test client source can be found in this file https://github.com/juks/SocketQueue/blob/master/lib/testSuite/lib/testClient.js

Moreover, the testClient is not used in my project here. Juste the Upstream.js

There must me some header misconfiguration, so you get no message.

The basic check the triggers "Invalid message!" notice is here https://github.com/juks/SocketQueue/blob/653ad6e888ebf6fb90399eaa4e8a216e103cbfda/lib/iso8583/lib/packager/smartVista.js#L313
