I think that you are missing the the rackup command. Here is how it is used:

<pre><code>rackup config.ru
</code></pre>

This is going to run your rack app on port 9292 using webrick. You can read "rackup --help" for more info how you can change these defaults.

About the app that you want to create. Here is how I think it should look like:

<pre><code># This is the root of our app
@root = File.expand_path(File.dirname(__FILE__))

run Proc.new { |env|
 # Extract the requested path from the request
 path = Rack::Utils.unescape(env['PATH_INFO'])
 index_file = @root + "#{path}/index.html"

 if File.exists?(index_file)
 # Return the index
 [200, {'Content-Type' =&gt; 'text/html'}, File.read(index_file)]
 # NOTE: using Ruby &gt;= 1.9, third argument needs to respond to :each
 # [200, {'Content-Type' =&gt; 'text/html'}, [File.read(index_file)]]
 else
 # Pass the request to the directory app
 Rack::Directory.new(@root).call(env)
 end
}
</code></pre>

blocks|key|1126732|text|您可以使用Rack::Static来完成此操作|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1126733|map+"/foo"+do

You can do this using Rack::Static

 run lambda {|*|}

blocks|key|911790|text|对我来说，使用Ruby2.0和Rack1.5.2，sinm+solution可以提供索引页面(这两个页面都是根目录的默认页面，也是显式加载的)，但对于其他文件，我得到了类似以下的错误：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|911791|Rack::Lint::LintError:+Status+must+be+>=100+seen+as+integer|code-block|syntax|javascript|911792|我将sinm解决方案与这个SO+answer和在Heroku+documentation上找到的代码片段结合起来，以获得所需的行为(假设整个站点包含在一个名为public的文件夹中)：|style|CODE|911793|use+Rack::Static,+

For me, using Ruby 2.0 and Rack 1.5.2, <a href="https://stackoverflow.com/a/11744018/753737">sinm solution</a> worked for serving the index page (both as default page for root and loaded explicitly), but for other files I obtained errors similar to the following:

<pre><code>Rack::Lint::LintError: Status must be &gt;=100 seen as integer
</code></pre>

I combined sinm solution with this <a href="https://stackoverflow.com/a/2271193/753737">SO answer</a> and the snippet found on <a href="https://devcenter.heroku.com/articles/static-sites-ruby#file-server-configuration" rel="nofollow noreferrer">Heroku documentation</a> to obtain the desired behavior (assuming that the entire site is contained in a folder called <code>public</code>):

<pre><code>use Rack::Static, 
 :urls =&gt; ["/images", "/js", "/css"],
 :root =&gt; "public",
 :index =&gt; 'index.html'

run Rack::File.new("public")
</code></pre>

I ended up on this page looking for a one liner...

If all you want is to serve the current directory for a few one-off tasks, this is all you need:

<pre><code>ruby -run -e httpd . -p 5000
</code></pre>

Details on how it works: <a href="http://www.benjaminoakes.com/2013/09/13/ruby-simple-http-server-minimalist-rake/">http://www.benjaminoakes.com/2013/09/13/ruby-simple-http-server-minimalist-rake/</a>

I'm trying to get some information from this tutorial: <a href="http://m.onkey.org/2008/11/18/ruby-on-rack-2-rack-builder">http://m.onkey.org/2008/11/18/ruby-on-rack-2-rack-builder</a>

basically I want to have a file <code>config.ru</code> that tell rack to read the current directory so I can access all the files just like a simple apache server and also read the default root with the index.html file...is there any way to do it?

my current <code>config.ru</code> looks like this:

<pre><code>run Rack::Directory.new('')
#this would read the directory but it doesn't set the root to index.html


map '/' do
 file = File.read('index.html')
 run Proc.new {|env| [200, {'Content-Type' =&gt; 'text/html'}, file] }
end
#using this reads the index.html mapped as the root but ignores the other files in the directory
</code></pre>

So I don't know how to proceed from here...

I've also tried this following the tutorials example but <code>thin</code> doesn't starts properly.

<pre><code>builder = Rack::Builder.new do

 run Rack::Directory.new('')

 map '/' do
 file = File.read('index.html')
 run Proc.new {|env| [200, {'Content-Type' =&gt; 'text/html'}, file] }
 end

end

Rack::Handler::Thin.run builder, :port =&gt; 3000
</code></pre>

Thanks in advance

我正在尝试从本教程中获得一些信息：基本上，我希望有一个文件config.ru，告诉rack读取当前目录，这样我就可以像访问简单的apache服务器一样访问所有文件，还可以使用index.html file...is读取默认根目录。有什么方法可以做到吗？我当前的config.ru如下所示：run Rack::Direct...
