需求：Python檢測URL狀態，并追加保存200的URL

代碼一：

#! /usr/bin/env python

#coding=utf-8

import sys

import requests

def getHttpStatusCode(url):

try:

request = requests.get(url)

httpStatusCode = request.status_code

return httpStatusCode

except requests.exceptions.HTTPError as e:

return e

if __name__ == "__main__":

with open('1.txt', 'r') as f:

for line in f:

try:

status = getHttpStatusCode(line.strip('\n'))#換行符

if status == 200:

with open('200.txt','a') as f:

f.write(line + '\n')

print line

else:

print 'no 200 code'

except Exception as e:

print e

代碼二：

#! /usr/bin/env python

# -*--coding:utf-8*-

import requests

def request_status(line):

conn = requests.get(line)

if conn.status_code == 200:

with open('url_200.txt', 'a') as f:

f.write(line + '\n')

return line13 else:

return None

if __name__ == '__main__':

with open('/1.txt', 'rb') as f:

for line in f:

try:

purge_url = request_status(line.strip('\n'))

except Exception as e:

pass

代碼三：

#! /usr/bin/env python

#coding:utf-8

import os,urllib,linecache

import sys

result = list()

for x in linecache.updatecache(r'1.txt'):

try:

a = urllib.urlopen(x.replace('/n','')).getcode()

#print x,a

except Exception,e:

print e

if a == 200:

#result.append(x) #保存

#result.sort() #排序結果

#open('2.txt', 'w').write('%s' % '\n'.join(result)) #保存入結果文件

with open ('200urllib.txt','a') as f: ## r只讀，w可寫，a追加

f.write(x + '\n')

else:

print 'error'
