WEBrick::HTTPServlet::ERBHandler
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 %>
Public Class Methods
new(server, name)
Creates a new ERBHandler on
server
that will evaluate and serve the ERB file
