WEBrick 是用 Ruby 寫的 web server, 若有開發 Web Service 需要也可以用, 但若開發 web 應用程式, 你應該用 Rails 比較好.
- WEBrick::HTTPServer 為 web server
- servlet class 請繼承自 HTTPServlet::AbstractServlet
require 'webrick' include WEBrick #a function stub to start WEBrick def start_WEBrick(config = {}) config.update(:Port => 2000) server = HTTPServer.new(config) yield server if block_given? ['INT', 'TERM'].each do |signal| trap(signal) { server.shutdown } end server.start end class HelloServlet < HTTPServlet::AbstractServlet def do_GET(req, res) res["content-type"] = "text/html; charset=UTF-8" res.body = %{ <html> <body> Hello World! </body> </html> } end alias do_POST do_GET end # start_WEBrick do |server| #servlet "/hello" server.mount("/hello", HelloServlet) end
- 啟動後請 http://localhost:2000/hello 就可以看到內容
- WEBrick 也可以處理靜態 html 網頁, 利用內建 HTTPServlet::FileHandler
# start_WEBrick do |server| #document root "/" doc_root = File.join(Dir.pwd, 'htdocs') server.mount("/", HTTPServlet::FileHandler, doc_root, {:FancyIndexing => true}) end
