Python中asyncore的用法实例

时间：2021-05-22

本文实例讲述了python中asyncore模块的用法，分享给大家供大家参考。具体方法如下：

实例代码如下:

##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 "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()

结果文件的内容为:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"><html><head><title>302 Found</title></head><body><h1>Found</h1><p>The document has moved <a href="http://www.python.org">here</a>.</p><hr><address>Apache/2.2.16 (Debian) Server at dinsdale.python.org Port 80</address></body></html>

希望本文所述对大家的Python程序设计有所帮助。
