How to fix Windows crashes
If you have Sinatra rdoc error on your system, I hope this guide will help you solve it.
Sinatra is the DSL forBuild Ruby Web Apps Quickly When Effort Is Crucial:
minimum 'sinatra' requiredget '/' do 'Hello World!'end
gem install sinatra
The code you change will not take effect until you restart the server.In general, restart the server every time you modify it or just use it.Sinatra/Charger.
It is also recommended to install
gem install which puma, Sinatrapick up when available.
yieldand nested layouts
In Sinatra, a route can be an HTTP method associated with a meaningful URL matching pattern.Each route is assigned a separate blocking route:
get '/' do .. demonstrate something ..endpost '/' do .. create something ..endput '/' make .. replace something ..endpatch'/' do ..a very important factor is changing..endremove '/' do ..destroy the topic..endThe '/' options do .. eliminate something ..endlink '/' make .. internet marketing something..endseparate '/' make .. separate something .. haveend
The routes are in the order they are listed. The first route thatmatches the invoked query.
get '/foo' do end
get around '/hello/:name' "Hi, #params['name']!"end
get '/hello/:name' do |n| "Hello #n!"end
Route templates can also contain available options with symbols (or wildcards).via the common array
get '/say/*/to/*' do params['splat'] endGet '/download/*.*' do params['splat'] end
get '/download/*.*' write |path, ext| [path, extension] end
get //hello/([w]+)/ do "Hello #params['capture'].first!"end
get %r/hello/([w]+) do |c| "Hey!"end
get '/posts/:format?' WITHmake end
get '/posts' do title documents = params['title'] Author equals params['author'] end
By the way, unless your organization disables Path Traversal cover (see below).below), the request path may appear changed toCompare with your routes.
You may be able to customize the sample personOptions that can be used for a route you specify that passes an important hash
get 'A/postsz', :mustermann_opts => :type => :regexp, :check_anchors => misunderstandings “When your entire family is patterned and grounded, clap your hands!”end
It looks like a status, but it’s not! These variations willcombined into hash
Routes can contain many match conditions, such as agent membership:
get '/foo', :agent => /Songbird (d.d)[d/]*?/ do "You are Songbird and are using the #params['agent'] version"endGet '/foo' do end
get '/', :host_name => /^admin./ do "Admin panel, access denied!"endget '/', => :provide 'html' will dob ham: indexendget '/', => : provide ['rss', 'atom', 'xml'] do Manufacturer: Liningend
set(:probability) valueget '/win_a_car', :probability => 0,1 do Won!"endGet "You do '/win_a_car' "Sorry, you lost."end
set(:auth) makes |*roles| condition other than connect_in? && roles. role Role redirect "/login/", 303 end endendget "/my/account/", :auth => [:user, :admin] do "Your User Account Information"endget "/only/admin/", :auth => :admin do "Only administrators can be allowed in here!" »end
The route block return price id is determined at least based on the response body.passed to help the HTTP client, or at least the following middleware inrack stack. Most often it is a business, as in the examples above.But similar values are also allowed.
You can return any object that will just be a valid rack response, rackMain subject or HTTP status code:
[Status (Integer), Header (Hash), Responsebody (responds to #each)]
[status (integer), response structure (responses to#each)]
#eachand only forwards mailthis block
Thus, for example, we can easily implement the developed example:
The lesson is being broadcast definitely everything 100. Specify "#in". endendget('/') Stream.new
You can also use the
stream gadget method (described below) to streamlineBoiler Dinner Plate and integrate route streaming logic.
