track

Streaming API: Methods | dev.twitter.comより

Specifies keywords to track. Phrases of keywords are specified by a comma-separated list. Queries are subject to Track Limitations, described in Track Limiting and subject to access roles, described in the statuses/filter method. Comma separated keywords and phrases are logical ORs, phrases are logical ANDs. Words within phrases are delimited by spaces. A tweet matches if any phrase matches. A phrase matches if all of the words are present in the tweet. (e.g. 'the twitter' is the AND twitter, and 'the,twitter' is the OR twitter.). Terms are exact-matched, and also exact-matched ignoring punctuation.
Exact matching on phrases, that is, keywords with spaces, is not supported. Keywords containing punctuation will only exact match tokens and, other than keywords prefixed by # and @, will tend to never match. Non-space separated languages, such as CJK and Arabic, are currently unsupported as tokenization occurs on whitespace. Other UTF-8 phrases should exact match correctly, but will not substitute similar characters to their least-common-denominator. For all these cases, consider falling back to the Search REST API.

Rubyのサンプルコード

#!/usr/bin/env ruby
# coding: utf-8

require 'net/http'
require 'uri'
require 'rubygems'
require 'json'

USERNAME = '_USERNAME_' # ここを書き換える
PASSWORD = '_PASSWORD_' # ここを書き換える

# URLが変更になってるみたい(2010/07/22)
#uri = URI.parse('http://stream.twitter.com/spritzer.json')
uri = URI.parse('http://stream.twitter.com/1/statuses/sample.json')

Net::HTTP.start(uri.host, uri.port) do |http|
  request = Net::HTTP::Get.new(uri.request_uri)
  # Streaming APIはBasic認証のみ
  request.basic_auth(USERNAME, PASSWORD)
  http.request(request) do |response|
    raise 'Response is not chuncked' unless response.chunked?
    response.read_body do |chunk|
      # 空行は無視する = JSON形式でのパースに失敗したら次へ
      status = JSON.parse(chunk) rescue next
      # 削除通知など、'text'パラメータを含まないものは無視して次へ
      next unless status['text']
      user = status['user']
      puts "#{user['screen_name']}: #{status['text']}"
    end
  end
end
