Is a global variable defined inside a Sinatra route shared between requests?

由 落爺英雄遲暮 提交于 2019-12-09 04:50:25
问题 Say I've got: get '/' do $random = Random.rand() response.body = $random end If I have thousands of requests per second coming to /, will the $random be shared and 'leak' outside the context or will it act like a 'local' variable to the get block? I imagine if it was defined outside of the context of get '/' do it would indeed be shared but I wonder if there's a mechanic to $ in ruby that I'm not aware of. 回答1: This part of the Sinatra README about scope is always helpful to read but if you

Is there an easy way to enable SSL support for Sinatra (using WEBRick for example)? 回答1: To do this with MRI ruby, use the following monkeypatch: sinatra_ssl.rb : require 'webrick/https' module Sinatra class Application def self.run! certificate_content = File.open(ssl_certificate).read key_content = File.open(ssl_key).read server_options = { :Host =>

Multipart response in Ruby/Rack

由 淺唱寂寞╮ 提交于 2019-12-09 01:23:50
问题 I want my server to send a multipart response (multipart/x-mixed-replace). I'd prefer some kind of solution using the Sinatra framework or a generic Rack app, but any example in ruby would be nice. Here's the equivalent of what I'm trying to do, in PHP: <?php header('Content-type: multipart/x-mixed-replace;boundary="rn9012"'); print "--rn9012\n"; print "Content-type: application/xml\n\n"; print "<?xml version='1.0'?>\n"; print "<content>First Part</content>\n"; print "--rn9012\n"; flush();

Working around the lack of context in Sinatra's route methods

由 故事扮演 提交于 2019-12-08 19:42:32
问题 I have been having an issue with missing instances and nilClass errors when calling my routes. After delving around within the source it seems like the generate_method call basically creates a new method using the block of the initial method. get "/" do @some_local_instance.do_something() end So in the above method there could very well be a local variable within that class called some_local_instance, however when the rote is actually evaluated it has no context as to where the method was

由 Deadly 提交于 2019-12-08 19:39:46

How to define a method to be called from the configure block of a modular sinatra application?

由 拜拜、爱过 提交于 2019-12-08 19:38:19
问题 I have a Sinatra app that, boiled down, looks basically like this: class MyApp < Sinatra::Base configure :production do myConfigVar = read_config_file() end configure :development do myConfigVar = read_config_file() end def read_config_file() # interpret a config file end end Unfortunately, this doesn't work. I get undefined method read_config_file for MyApp:Class (NoMethodError) The logic in read_config_file is non-trivial, so I don't want to duplicate in both. How can I define a method that
