我正在尝试捕获特定标签的twitter流,以便将其作为另一个http流传递我编写的代码(我是Ruby新手)如下:

    require 'tweetstream'
    require 'sinatra'

    set :server, 'webrick'
    connections = []

    TweetStream.configure do |config|
      config.consumer_key       = 'XXX'
      config.consumer_secret    = 'XXX'
      config.oauth_token        = 'XXX'
      config.oauth_token_secret = 'XXX'
      config.auth_method        = :oauth
    end


    get '/hi' do
      "Hello World!"
    end

    get '/evented', provides: 'text/event-stream' do
      stream :keep_open do |out|
        connections.push out
        out.callback { connections.delete( out ) }
      end
    end

    TweetStream::Client.new.track('#worldcup') do |status|
      connections.each do |out|
        out << "#{status.text}"
      end
    end

当我运行这个程序时,我得到:

奇怪的是,如果我使用sinatra并删除“TweetStream::Client.new.track”部分,一切都会正常工作在控制台中使用tweetstream输出也是如此但是,如果我同时使用它们,我就无法与浏览器建立连接。

最佳答案

如上所述,服务器应设置为thin
由于事件的性质,我不确定上面的random_tweet_about函数如何工作。
我可以通过在一个TweetStream::Client.new块中包装EM.schedule来让tweetstream与sinatra一起工作。也许竞争的事件循环要求它在另一个线程中。

require 'sinatra'
require 'tweetstream'

set :server, 'thin'

twitter = YAML.load_file('twitter.yml')['twitter']

TweetStream.configure do |config|
  config.consumer_key       = twitter['CONSUMER_KEY']
  config.consumer_secret    = twitter['CONSUMER_SECRET']
  config.oauth_token        = twitter['ACCESS_TOKEN']
  config.oauth_token_secret = twitter['ACCESS_SECRET']
  config.auth_method        = :oauth
end

connections = []

get '/tweets', provides: 'text/event-stream' do
  stream :keep_open do |out|
    connections << out
    out.callback { connections.delete(out) }
  end
end

EM.schedule do
  TweetStream::Client.new.track('#yolo') do |status|
    connections.each do |out|
      out << status.text
    end
  end
end
