Python 实现域名解析为ip的方法

今天得了一批域名,需要把域名解析成ip

因为量比较大所以采用了多进程和队列的方式

from multiprocessing import Process,Queue,Pool

import socket

import multiprocessing

import os

#写入文件

def write(q,lock,filename):

while not q.empty():

url = q.get()

print (url)

try:

ip = socket.gethostbyname(url)

except:

ip = "unknow"

print (ip)

with open(filename,'a+') as f:

lock.acquire() #加锁防止多个进程写入会混乱

try:

f.write(url + " " + ip + "\n")

finally:

lock.release()

#添加到队列

def readurl(q,n):

with open(str(n)+'.txt','r') as f:

lines = f.readlines()

for line in lines:

q.put(line.strip())

return q

#根据进程进行拆分txt

def multi(urllist,n):

with open(urllist,'r') as f:

lines = f.readlines()

line = int(len(lines)/n)

print (line)

for m in range(0,n):

with open(str(m)+'.txt','a+') as f1:

for i in range(line*m,line*(m+1)):

f1.write(lines[i])

#删除拆分的txt文件

def remove(n):

for i in range(0,n):

os.remove(str(i)+'.txt')

print ("######清除临时文件######")

if __name__ == "__main__":

manager = multiprocessing.Manager()

q = manager.Queue()

lock = manager.Lock()

m = 5 #设置扫描进程数

urllist = "url.txt" #待解析的url

filename = "test.txt" #结果保存的文件名

multi(urllist,m)

p = Pool(m)

for i in range(m):

p.apply_async(write,args=(readurl(q,i),lock,filename))

p.close()

p.join()

remove(m)

print ("#######全部文件采集完成########")
