本文執行個體講述了python中asyncore模組的用法,分享給大家供大家參考。具體方法如下:
執行個體代碼如下:
##asyncore import asyncore,socket ######################################################################## class AsyncGet(asyncore.dispatcher): """ the defined class """ #---------------------------------------------------------------------- def __init__(self, host): """Constructor""" asyncore.dispatcher.__init__(self) self.host = host self.create_socket(socket.AF_INET, socket.SOCK_STREAM) self.connect((host, 80)) self.request = "Get /index.html HTTP/1.0\r\n\r\n" self.outf = None print "串連 :", host def handle_connect(self): print 'connect:', self.host pass def handle_read(self): if not self.outf: print '正在串連:',self.host self.outf = open("%s.txt" % self.host, 'wb') data = self.recv(8192) if data: self.outf.write(data) pass def handle_writebale(self): return len(self.request) def handle_write(self): num_sent = self.send(self.request) pass def handle_close(self): asyncore.dispatcher.close(self) print "socket close in:",self.host if self.outf: self.outf.close() pass if __name__ == "__main__": AsyncGet("www.python.org") asyncore.loop() import asyncore,socket ######################################################################## class AsyncGet(asyncore.dispatcher): """ the defined class """ #---------------------------------------------------------------------- def __init__(self, host): """Constructor""" asyncore.dispatcher.__init__(self) self.host = host self.create_socket(socket.AF_INET, socket.SOCK_STREAM) self.connect((host, 80)) self.request = "Get /index.html HTTP/1.0\r\n\r\n" self.outf = None print "串連 :", host def handle_connect(self): print 'connect:', self.host pass def handle_read(self): if not self.outf: print '正在串連:',self.host self.outf = open("%s.txt" % self.host, 'wb') data = self.recv(8192) if data: self.outf.write(data) pass def handle_writebale(self): return len(self.request) def handle_write(self): num_sent = self.send(self.request) pass def handle_close(self): asyncore.dispatcher.close(self) print "socket close in:",self.host if self.outf: self.outf.close() pass if __name__ == "__main__": AsyncGet("www.python.org") asyncore.loop()
