python 中asyncore模块的使用:

代码:

##asyncoreimport 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 "连接 :", host            def handle_connect(self):        print 'connect:', self.host        pass    def handle_read(self):        if not self.outf:            print '正在连接:',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 "连接 :", host            def handle_connect(self):        print 'connect:', self.host        pass    def handle_read(self):        if not self.outf:            print '正在连接:',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()
