私は、(少なくとも今は) TwitchTV (ストリーミング プラットフォーム) からストリーム情報を取得するプログラムを作成しています。このプログラムは自己啓発用ですが、実行すると、ストリーマーの名前だけを出力するのに 2 分かかります。
とにかく重要な場合は、Windows7でPython 2.7.3 64ビットを使用しています。
クラス.py:
#imports:
import urllib
import re
#classes:
class Streamer:
#constructor:
def __init__(self, name, mode, link):
self.name = name
self.mode = mode
self.link = link
class Information:
#constructor:
def __init__(self, TWITCH_STREAMS, GAME, STREAMER_INFO):
self.TWITCH_STREAMS = TWITCH_STREAMS
self.GAME = GAME
self.STREAMER_INFO = STREAMER_INFO
def get_game_streamer_names(self):
"Connects to Twitch.TV API, extracts and returns all streams for a spesific game."
#start connection
self.con = urllib2.urlopen(self.TWITCH_STREAMS + self.GAME)
self.info = self.con.read()
self.con.close()
#regular expressions to get all the stream names
self.info = re.sub(r'"teams":\[\{.+?"\}\]', '', self.info) #remove all team names (they have the same name: parameter as streamer names)
self.streamers_names = re.findall('"name":"(.+?)"', self.info) #looks for the name of each streamer in the pile of info
#run in a for to reduce all "live_user_NAME" values
for name in self.streamers_names:
if name.startswith("live_user_"):
self.streamers_names.remove(name)
#end method
return self.streamers_names
def get_streamer_mode(self, name):
"Returns a streamers mode (on/off)"
#start connection
self.con = urllib2.urlopen(self.STREAMER_INFO + name)
self.info = self.con.read()
self.con.close()
#check if stream is online or offline ("stream":null indicates offline stream)
if self.info.count('"stream":null') > 0:
return "offline"
else:
return "online"
main.py:
#imports:
from classes import *
#consts:
TWITCH_STREAMS = "https://api.twitch.tv/kraken/streams/?game=" #add the game name at the end of the link (space = "+", eg: Game+Name)
STREAMER_INFO = "https://api.twitch.tv/kraken/streams/" #add streamer name at the end of the link
GAME = "League+of+Legends"
def main():
#create an information object
info = Information(TWITCH_STREAMS, GAME, STREAMER_INFO)
streamer_list = [] #create a streamer list
for name in info.get_game_streamer_names():
#run for every streamer name, create a streamer object and place it in the list
mode = info.get_streamer_mode(name)
streamer_name = Streamer(name, mode, 'http://twitch.tv/' + name)
streamer_list.append(streamer_name)
#this line is just to try and print something
print streamer_list[0].name, streamer_list[0].mode
if __name__ == '__main__':
main()
プログラム自体は完璧に動作しますが、本当に遅いです
何か案は？
