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
importasyncore,socket
########################################################################
classAsyncGet(asyncore.dispatcher):
"""
thedefinedclass
"""
#----------------------------------------------------------------------
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.htmlHTTP/1.0\r\n\r\n"
self.outf=None
print"连接:",host
defhandle_connect(self):
print'connect:',self.host
pass
defhandle_read(self):
ifnotself.outf:
print'正在连接:',self.host
self.outf=open("%s.txt"%self.host,'wb')
data=self.recv(8192)
ifdata:
self.outf.write(data)
pass
defhandle_writebale(self):
returnlen(self.request)
defhandle_write(self):
num_sent=self.send(self.request)
pass
defhandle_close(self):
asyncore.dispatcher.close(self)
print"socketclosein:",self.host
ifself.outf:
self.outf.close()
pass
if__name__=="__main__":
AsyncGet("www.python.org")
asyncore.loop()
importasyncore,socket
########################################################################
classAsyncGet(asyncore.dispatcher):
"""
thedefinedclass
"""
#----------------------------------------------------------------------
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.htmlHTTP/1.0\r\n\r\n"
self.outf=None
print"连接:",host
defhandle_connect(self):
print'connect:',self.host
pass
defhandle_read(self):
ifnotself.outf:
print'正在连接:',self.host
self.outf=open("%s.txt"%self.host,'wb')
data=self.recv(8192)
ifdata:
self.outf.write(data)
pass
defhandle_writebale(self):
returnlen(self.request)
defhandle_write(self):
num_sent=self.send(self.request)
pass
defhandle_close(self):
asyncore.dispatcher.close(self)
print"socketclosein:",self.host
ifself.outf:
self.outf.close()
pass
if__name__=="__main__":
AsyncGet("www.python.org")
asyncore.loop()
结果文件的内容为:
