Question

我正在玩Sinatra，我想让我的一条路线不区分大小写。我尝试添加这样的路线：

get "(?i)/tileflood/?" do
end

但它与预期的/ tileflood的任何排列都不匹配。我在rubular.com上测试了以下正则表达式，它匹配得很好。我错过了什么吗？

\/(?i)tileflood\/?

你想要一条真正的正则表达式：

require 'sinatra'
get %r{^/tileflood/?$}i do
  request.url + "\n"
end

证明：

smagic:~ phrogz$ curl http://localhost:4567/tileflood
http://localhost:4567/tileflood

smagic:~ phrogz$ curl http://localhost:4567/tIlEflOOd
http://localhost:4567/tIlEflOOd

smagic:~ phrogz$ curl http://localhost:4567/TILEFLOOD/
http://localhost:4567/TILEFLOOD/

smagic:~ phrogz$ curl http://localhost:4567/TILEFLOOD/z
<!DOCTYPE html>

  <style type="text/css">

    color:#888;margin:20px}
  #c {margin:0 auto;width:500px;text-align:left}
  </style>
</head>
<body>
  <h2>Sinatra doesn't know this ditty.</h2>

  <div id="c">
    Try this:
    <pre>get '/TILEFLOOD/z' do
  "Hello World"
end</pre>
  </div>
</body>
</html>

  #c {margin:0 auto;width:500px;text-align:left}
  </style>
</head>
<body>

如何在Sinatra中创建不区分大小写的路由？
