Rack: Wie speichern Sie die URL als Variable?

Question

Ich schreibe eine einfache statische Rack App. Überprüfen Sie den Code config.ru aus unter:

use Rack::Static, 
    :urls => ["/elements", "/img", "/pages", "/users", "/css", "/js"], 
    :root => "archive" 


map '/' do 
    run Proc.new { |env| 
    [ 
     200, 
     { 
     'Content-Type' => 'text/html', 
     'Cache-Control' => 'public, max-age=6400' 
     }, 
     File.open('archive/splash.html', File::RDONLY) 
    ] 
    } 
end 

map '/pages/search.html' do 
    run Proc.new { |env| 
    [ 
     200, 
     { 
     'Content-Type' => 'text/html', 
     'Cache-Control' => 'public, max-age=6400' 
     }, 
     File.open('archive/pages/search.html', File::RDONLY) 
    ] 
    } 
end 

map '/pages/user.html' do 
    run Proc.new { |env| 
    [ 
     200, 
     { 
     'Content-Type' => 'text/html', 
     'Cache-Control' => 'public, max-age=6400' 
     }, 
     File.open('archive/pages/user.html', File::RDONLY) 
    ] 
    } 
end 

# Each map section is repeated for each HTML page served 

Ich möchte dies vereinfachen, indem die URL als Variable zu speichern und die Erstellung eines Kartenausschnittes, die

map url do 
    run Proc.new { |env| 
    [ 
     200, 
     { 
     'Content-Type' => 'text/html', 
     'Cache-Control' => 'public, max-age=6400' 
     }, 
     File.open('archive' + url, File::RDONLY) 
    ] 
    } 
end 

sagt Wie kann ich diese URL richtig eingestellt Variable?

Answer 1

Sie sollten den Kartenteil nicht benötigen.

run Proc.new { |env| 
    [ 
    200, 
    { 
     'Content-Type' => 'text/html', 
     'Cache-Control' => 'public, max-age=6400' 
    }, 
    File.open('archive' + env['PATH_INFO'], File::RDONLY) 
    ] 
} 

Answer 2

Wie wäre:

static_page_mappings = { 
    '/'     => 'archive/splash.html', 
    '/pages/search.html' => 'archive/pages/search.html' 
    '/pages/user.html' => 'archive/pages/user.html', 
} 

static_page_mappings.each do |req, file| 
    map req do 
    run Proc.new { |env| 
     [ 
     200, 
     { 
      'Content-Type' => 'text/html', 
      'Cache-Control' => 'public, max-age=6400', 
     }, 
     File.open(file, File::RDONLY) 
     ] 
    } 
    end 
end
