Python中asyncore的用法实例
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:

希望本文所述对大家的Python程序设计有所帮助。
