需求：Python检测URL状态，并追加保存200的URL

代码一：

#! /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'))#换行符
 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

代码二：

#! /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

代码三：

#! /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() #排序结果
 #open('2.txt', 'w').write('%s' % '\n'.join(result)) #保存入结果文件
 with open ('200urllib.txt','a') as f: ## r只读，w可写，a追加
 f.write(x + '\n')
 else:
 print 'error'
