ERBHandler
evaluates an ERB file and returns the result. This handler is automatically used if there are .rhtml files in a directory served by the FileHandler
.
ERBHandler
supports GET and POST methods.
The ERB file is evaluated with the local variables servlet_request
and servlet_response
which are a WEBrick::HTTPRequest
and WEBrick::HTTPResponse
respectively.
Example .rhtml file:
Request to <%= servlet_request.request_uri %> Query params <%= servlet_request.query.inspect %>
Creates a new ERBHandler
on server
that will evaluate and serve the ERB file name
# File webrick/httpservlet/erbhandler.rb, line 42 def initialize(server, name) super(server, name) @script_filename = name end
Handles GET requests
# File webrick/httpservlet/erbhandler.rb, line 50 def do_GET(req, res) unless defined?(ERB) @logger.warn "#{self.class}: ERB not defined." raise HTTPStatus::Forbidden, "ERBHandler cannot work." end begin data = File.open(@script_filename, &:read) res.body = evaluate(ERB.new(data), req, res) res['content-type'] ||= HTTPUtils::mime_type(@script_filename, @config[:MimeTypes]) rescue StandardError raise rescue Exception => ex @logger.error(ex) raise HTTPStatus::InternalServerError, ex.message end end
