Simple chat system over websockets with reconnection feature

由 偶尔善良 提交于 2019-12-10 23:44:25
问题 I have seen many examples of chat room systems over websocket implemented with erlang and cowboy. Most of the examples I have seen use gproc. In practice each websocket handler registers itself with gproc and then broadcasts/receives messages from it. Since a user could close by accident the webpage I am thinking about connecting to the websocket handler a gen_fsm which actually broadcasts/receives all the messages from gproc. In this way the gen_fsm could switch from a "connected" state to a

Rebar3 + Cowboy Kernel PID Terminated

问题 I installed rebar3 and created a new release with cd ~/apps rebar3 new release tunnel Then I copied my src files from ~/tunnel/src/* to ~/apps/tunnel/src/ I ran into a compile error with rebar3 run and found Erlang "Kernel pid terminated" error as a possible solution. I renamed everything about tunnel_app to tunnel . So my src contains tunnel.erl , tunnel.app.src and tunnel_sup.erl . I renamed the module definition as appropriate. Here's the rebar3 run error: ~/apps/tunnel:.rebar3 run ===>

Facing intermittent 404 issue when calling Rails API

由 会有一股神秘感。 提交于 2019-12-02 04:21:36
I have banged my head on this for 2 days now and i dint find any luck yet. Looking for help on this. The issue: Front End makes 10 similar XHR requests ( for different users ) to my Rails API and few of the requests randomly fails with 404 status code. My Observations: If i make the same request again, It passes. I dont see any trace of 404 requests even hitting my server ( using logs ). I do see different response headers for 200 and 404 ( mentioned below ) and i see cowboy ( https://github.com/heroku/cowboyku , https://github.com/heroku/vegur ) server for 404 requests. I run my rails

How do you use Gun as a Cowboy client?

问题 I followed the Getting Started instructions for Cowboy, and I've got Cowboy running and listening on port 8080, and I got the Hello Erlang! response when I entered http://localhost:8080 in my browser. Now, how do I use Gun to connect to Cowboy? I read the Gun docs, and it says to add "Gun as an erlang.mk dependency". So I downloaded erlang.mk: ~/erlang_programs/my_gun$ curl -O https://erlang.mk/erlang.mk and following the Erlang.mk User Guide, I created an application: ~/erlang_programs/my
