Phoenix.Endpoint.Cowboy2Adapter (Phoenix v1.5.7) View Source
The Cowboy2 adapter for Phoenix.
Endpoint configuration
This adapter uses the following endpoint configuration:
:http
- the configuration for the HTTP server. It accepts all options as defined byPlug.Cowboy
. Defaults tofalse
:https
- the configuration for the HTTPS server. It accepts all options as defined byPlug.Cowboy
. Defaults tofalse
:drainer
- a drainer process that triggers when your application is shutting to wait for any on-going request to finish. It accepts all options as defined byPlug.Cowboy
. Defaults to[]
and can be disabled by setting it to false.
Custom dispatch options
You can provide custom dispatch options in order to use Phoenix's builtin Cowboy server with custom handlers. For example, to handle raw WebSockets as shown in Cowboy's docs).
The options are passed to both :http
and :https
keys in the
endpoint configuration. However, once you pass your custom dispatch
options, you will need to manually wire the Phoenix endpoint by
adding the following rule:
{:_, Phoenix.Endpoint.Cowboy2Handler, {MyAppWeb.Endpoint, []}}
For example:
config :myapp, MyAppWeb.Endpoint,
http: [dispatch: [
{:_, [
{"/foo", MyAppWeb.CustomHandler, []},
{:_, Phoenix.Endpoint.Cowboy2Handler, {MyAppWeb.Endpoint, []}}
]}]]
It is also important to specify your handlers first, otherwise Phoenix will intercept the requests before they get to your handler.
