Setting control, plug, cowboy options

[randy....@gmail.com]

Hi,

Starting converting an app over to use phoenix & elixir 1.0+.  I'm working with large files, and need to increase the default limit set by the cowboy adapter.

https://github.com/elixir-lang/plug/blob/324348bea1270a9a16c07d82d93661c80de2e763/lib/plug/adapters/cowboy/conn.ex#L65

which is called by the multipart plug:

https://github.com/elixir-lang/plug/blob/f3f0bd69b549532c420c237062cf051d5c9a2e8f/lib/plug/parsers/multipart.ex

This is my first time using Plug, so - not quite sure where to init Plug.Conn with the option within Phoenix.  I am looking to set it at the controller level.

For the controller, I am not using Plug.Upload directly, I use the reference supplied by Plug.Conn.  Thus, I am not sure how to pass the length option so the Connection will use it.  How can this be done?

I'd like to know where this should be set (if not at the controller), and what some options for setting the options are?

Thanks

Perhaps another way to ask this is:

Where do I set the options for a controller?  Are these options passed to Plug.Adapters.Cowboy.Conn?  If not, is there any way to pass options into that adapter?

Hey Randy,

You should be able to accomplish this within the `http` options, i.e.

    config :phoenix, MyApp.Router,

      ...

      http: [length: 10_000_000]

These values can only be set per router, not per controller. Phoenix supports multiple Routers though if you absolutely have to isolate this setting. Let me know if that works for you.

Hey Chris,

Thanks for looking into this.  Setting the option as part of the router http config was one of the things I did try.  I'm not sure the option setting is making it down to Plug.Upload however.

Here is the stack trace I ultimately see ... when I send in a large file:

Yep - that works.  Thanks Chris!

I misspoke, the parser option is what you need to configure:

  parsers: [parsers: [:urlencoded, :multipart, :json],

            accept: ["*/*"],

            json_decoder: Poison,

            length: 100_000_000],

Give that a shot and report back.

How to produce gzip compressed response? I tried to add a configuration to config.exs but it didn't seem to work.

config :cowboy,

  compress: true 

Thanks.

Got it working by adding compress: true to Phoenix.Endpoint.http

config :app_name, AppName.Endpoint,

  ...

  http: [compress: true]
