How to Access HTML Request Parameters for a .Rhtml Page Served by Webrick

How to access html request parameters for a .rhtml page served by webrick?

According to the source code of erbhandler it runs the rhtml files this way:

    Module.new.module_eval{
      meta_vars = servlet_request.meta_vars
      query = servlet_request.query
      erb.result(binding)
    }

So the binding should contain a query (which contains a hash of the query string) and a meta_vars variable (which contains a hash of the environment, like SERVER_NAME) that you can access inside the rhtml files (and the servlet_request and servlet_response might be available too, but I'm not sure about them).

If that is not the case you can also try querying the CGI parameter ENV["QUERY_STRING"] and parse it, but this should only be as a last resort (and it might only work with CGI files).

Mongrel: how to process erb in .rhtml file

After looking through the code of the DirHandler class in Mongrel, it seems that this class is not made for applying any processing to a file, but just serving it up as is.

It seems the only way to do this in Mongrel would be to modify DirHandler or write your own HttpHandler.

lib/dps/compression.rb

module Dps 
  class Compression
    def initialize(app)  
      @app = app  
    end  

    def call(env)  
      status, headers, response = @app.call(env)
      if File.extname(env['REQUEST_URI']) == ".svgz" && status == 200 
        headers["Content-Encoding"] = "gzip"
      else
        nil 
      end 
      [status, headers, response]
    end  
  end 
end

config/application.rb

config.autoload_paths += Dir["#{config.root}/lib/**/"]
config.middleware.insert_before("ActionDispatch::Static", "Dps::Compression")

Generate HTML page using rails without a webserver

I've found a solution:

require '/path/to/application.rb'
app = APPName::Application.initialize!
session = ActionDispatch::Integration::Session.new(app)
session.get '/'
puts session.body
