flvのurlは取れない！！
もう使わなさそう。

twistedっていうのを発見！upnp機器検出してみる。
#!/usr/bin/env python # -*- coding: utf-8 -*- from twisted.internet.protocol import DatagramProtocol from twisted.internet import reactor # udp_listener class udp_listener(): # listen def listen(self, datagram, address): print "from:", address print "datagram: " + repr(datagram) # MSearchListener class m_search_listener(udp_listener): # listen def listen(self, datagram, address): print "from address: " , address[0] print "from port: " , address[1] print "-" * 20 device = self.__parse(datagram) for key in device.keys(): print key, " = ", device[key] def __parse(self, datagram): values = repr(datagram).split("\\r\\n") result = {} for value in values: datas = value.split(":", 1) if datas[0] == "\r\n": break elif not len(datas) == 2: continue else: result[datas[0]] = datas[1].strip() return result class m_search(DatagramProtocol): # request M_SEARCH_REQUEST = "M-SEARCH * HTTP/1.1\r\n" + \ "MX: 3\r\n" + \ "HOST: 239.255.255.250:1900\r\n" + \ "MAN: \"ssdp:discover\"\r\n" + \ "ST: upnp:rootdevice\r\n\r\n" def __init__(self, listener = udp_listener()): self.listener = listener def datagramReceived(self, datagram, address): self.listener.listen(datagram, address) if __name__ == "__main__": client = m_search(m_search_listener()) reactor.listenUDP(0, client).write(m_search.M_SEARCH_REQUEST, ('239.255.255.250', 1900)) reactor.run()
結果:

複数upnp機器あっても大丈夫？
twistedの使い方がよく分からない。
reactor.run()で止まる。止めないことはできる？

m-searchでupnp機器検出してみる
#!/usr/bin/env python # -*- coding: utf-8 -*- import socket import traceback # m_search class m_search: # M_SEARCH_REQUEST M_SEARCH_REQUEST = "M-SEARCH * HTTP/1.1\r\n" + \ "MX: 3\r\n" + \ "HOST: 239.255.255.250:1900\r\n" + \ "MAN: \"ssdp:discover\"\r\n" + \ "ST: upnp:rootdevice\r\n\r\n" # BRODCAST_ADDRESS BRODCAST_ADDRESS = "239.255.255.250" # PORT PORT = 1900 def __init__(self): pass def getDevice(self): # getDevice s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.sendto(m_search.M_SEARCH_REQUEST, (m_search.BRODCAST_ADDRESS, m_search.PORT)) try: file = s.makefile() return self._parse(file) except: traceback.print_exc() finally: file.close() s.close() def _parse(self, file): # parse result = {} for line in file: if not line: break else: datas = line.split(":", 1) if datas[0] == "\r\n": break elif not len(datas) == 2: continue else: result[datas[0]] = datas[1].strip() return result if __name__ == "__main__": device = m_search().getDevice() for key in device.keys(): print key, " = ", device[key]

TODO: upnp機器が複数あったらダメじゃない？
TkinterよりwxPythonのがいいという噂なのでwxPythonで作成

wxPythonはサンプルも多いのでpythonでGUIやるならwxPythonで決定。
スクロールも自動的に。
列ごとのサイズの設定もできる。
TkinterでGUI作成。
昨日のAmazonClient使って本を検索。
#!/usr/bin/env python # -*- coding: utf-8 -*- import Tkinter as Tk import tktable as ta import amazon as am """ AmazonBookSearchFrame""" class AmazonBookSearchFrame(Tk.Frame): def __init__(self, master = None): Tk.Frame.__init__(self, master) self.master.wm_geometry("650x300+250+200") self.master.title(u"Amazon 本検索") #タイトルラベル titleLabel = Tk.Label(self, master, text = u"タイトル入力！！", font=('Helvetica', '10', 'bold')) titleLabel.grid(row = 0, column = 0, padx = 0, pady = 0) #タイトル入力 self.titleStrVar = Tk.StringVar() self.titleInputEntry = Tk.Entry(self, textvariable = self.titleStrVar) self.titleInputEntry.grid(row = 1, column = 0, padx = 5, pady = 5) # 検索ボタン button = Tk.Button(self, text="検索", command=self.search, width = 10) button.grid(row = 1, column = 1, padx = 5, pady = 5) # テーブル self.tableVar = ta.ArrayVar(self) self.__set_table_title() table = ta.Table(self, rows=10, cols=3, state='disabled', width=10, height=10, titlerows=1, colwidth=30, variable=self.tableVar, selecttype='row') table.grid(row = 2, column = 0, columnspan = 2, sticky=Tk.W + Tk.E + Tk.N + Tk.S) def __set_table_title(self): # 列名設定 titles = (u"タイトル", u"評価", u"値段") for i in range(len(titles)): index = "%d,%d" % (0, i) self.tableVar.set(index, titles[i]) def search(self): # 検索開始 param = {am.SearchWordType.TITLE: self.titleStrVar.get()} client = am.AmazonClient(param) response = client.doRequest() tableVar = self.tableVar if len(response) > 0: indexList = [] for i in range(1, len(response)): indexList = ["%d,%d" % (i, x) for x in range(4)] print indexList tableVar.set(indexList[0], response[i].title) tableVar.set(indexList[1], response[i].averagerating) tableVar.set(indexList[2], response[i].price + u"円") if __name__ == "__main__": main = AmazonBookSearchFrame() main.pack() main.mainloop()
tktableの使い方がよく分からないので調査中。
もっと色々と細かい設定がしたい。そもそもできるのか？
