新手求解答多线程问题
本帖最后由 coolxl2014 于 2014-12-26 16:00 编辑麻烦大牛帮忙看下这个脚本，用socket.connect分别去连接192.168.2.x这个ip段的15个端口，扫描开放状态。超时是2秒，根据我新手的理解。如果扫描1个ip的15个端口，15个线程，应该2秒内能打印出所以结果。但实际情况是结果一条条往外冒，和单线程一样慢。 求大牛帮小弟指出错误。多谢~# -*- coding: utf-8 -*-
import threading, socket
def host_list(start,end):
for i in range(start,end,1):
ip = net+str(i)
for x in PortList:
port = x
tmp = []
tmp.append(ip)
tmp.append(port)
list.append(tmp)
return list
def scan(list):
while True:
if len(list)>0:
lock.acquire()
host = list.pop()
lock.release()
ip = host
port = host
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(Timeout)
address = (ip, port)
try:
sock.connect(address)
print ip,port,'True'
except:
sock.close()
print ip,port,'False'
sock.close()
else:
break
def threads(x):
thread_tmp=[]
for i in range(x):
new_thread=threading.Thread(target=scan(host), args=(i),name='thread'+str(i))
thread_tmp.append(new_thread)
for i in thread_tmp:
i.start()
i.join()
if __name__ == '__main__':
net = '192.168.2.'
Timeout = 2.0
PortList =
list = []
true_list = []
false_list = []
lock = threading.Lock()
host = host_list(1,2)
threads(15)
没仔细看，感觉这里这么写吧for i in thread_tmp:
i.start()
for i in thread_tmp:
i.join()
