我使用Ruby 1.9.3在本地主機上運行一個簡單的goliath服務器,它不是異步運行http請求。下面的代碼:Goliath不是異步的
require 'goliath'
require 'em-synchrony'
require 'em-synchrony/em-http'
class Server < Goliath::API
use Goliath::Rack::Validation::RequestMethod, %w(GET PUT POST)
def initialize
super
puts "Started up Bookcover server... Let 'em come!"
end
def response(env)
thumbnail_cover_url, large_book_cover_url = ["http://riffle-bookcovers.s3.amazonaws.com/B00GJYXA5I-thumbnail.jpg", "http://riffle-bookcovers.s3.amazonaws.com/B00GJYXA5I-original.jpg"]
puts "start"
a = EM::HttpRequest.new(thumbnail_cover_url).get
b = EM::HttpRequest.new(large_book_cover_url).get
puts "done"
[200, {}, "Hello World"]
end
end
當我運行ab -n 100 http://127.0.0.1:9000/
我可以看到它等待每個請求完成,這意味着呼叫阻塞。
但是,根據文獻Goliath使用Em-synchrony讓我編寫「同步外觀」的代碼,這裏不是這種情況。
我會很感激任何提示和意見!
