Problems and solutions encountered using Python scripts to implement batch website survival detection

When doing penetration testing, there is a relatively large project with hundreds of websites, so you must first determine which websites are normal and which websites are abnormal. So I wrote a small script for easy use in the future.

The specific implementation code is as follows:

#!/usr/bin/python
# -*- coding: UTF-8 -*-
'''

'''
import requests
import sys
f = open('url.txt', 'r')
url = f.readlines()
length = len(url)
url_result_success=[]
url_result_failed=[]
for i in range(0,length):
try:
response = requests.get(url[i].strip(), verify=False, allow_redirects=True, timeout=5)
if response.status_code != 200:
raise requests.RequestException(u"Status code error: {}".format(response.status_code))
except requests.RequestException as e:
url_result_failed.append(url[i])
continue
url_result_success.append(url[i])
f.close()
result_len = len(url_result_success)
for i in range(0,result_len):
print '网址%s' % url_result_success[i].strip()+'打开成功'

The test results are as follows:

Problems encountered:

When I first started testing, if I encountered an error that could not be made or did not exist, I would directly report an error and stop the program. Later I found out that it was because response.status_code != 200 was wrong when getting the status code here.

Because some websites will not return a status code if they cannot be opened. So the program doesn’t know! ==What to do with 200?

Solution:

Use try except else to catch exceptions

The specific code is:

try:
response = requests.get(url[i].strip(), verify=False, allow_redirects=True, timeout=5)
if response.status_code != 200:
raise requests.RequestException(u"Status code error: {}".format(response.status_code))
except requests.RequestException as e:
url_result_failed.append(url[i])
continue

The above is the problem and solution introduced by the editor to use Python scripts to implement batch website survival detection. I hope it will be helpful to you.
