Attribute Error

[DiceMann]

I am doing an online course and when i run the program, i get an error message of:

Output:
Traceback (most recent call last):
  File "vulnerability_scanner.py", line 9, in <module>
    vuln_scanner.session.post("http://10.0.2.4/dvwa/login", data=data_dic)
AttributeError: Scanner instance has no attribute 'session'
root@kali:~/PycharmProjects/vulnerability_scanner# 

Here is a copy of my code..now, im using pycharm so I have two different programs that i have separately coded that work in tandem, if you will so the scanner is here:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

#!/usr/bin/env python   import requests import re import urlparse     class Scanner:     def __init__(self, url):         self.target_url = url         self.target_links = []         self.session = requests.Session()       def extract_links_from(self, url):         response = self.session.get(url)         return re.findall('(?:href=")(.*?)"', response.content.decode('utf-8', 'ignore'))       def crawl(self, url=None):         if url is None:             url = self.target_url         href_links = self.extract_links_from(url)         for link in href_links:             link = urlparse.urljoin(url, link)               if "#" in link:                 link = link.split("#")[0]               if self.target_url in link and link not in self.target_links:                 self.target_links.append(link)                 print(link)                 self.crawl(link)

And the other program, named vulnerability_scanner is here:

1 2 3 4 5 6 7 8 9 10 11

#!/usr/bin/env python   import scanner   target_url = "http://10.0.2.4/dvwa/" data_dic = {"username": "admin", "password": "password", "Login": "submit"}   vuln_scanner = scanner.Scanner(target_url) vuln_scanner.session.post("http://10.0.2.4/dvwa/login", data=data_dic)   vuln_scanner.crawl()

(The url is apart of metaslpoitable, a vulnerable operating system by design)

Running the program is the conventional vulnerability_scanner.py and sure enough, I get the error message.


Any and all help, along with formatting my code to whatever you guys ask would be great.

One thing that comes to my mind - you changed scanner.py to include Scanner.session and didn't save the file yet. I don't remember if PyCharm had autosave function. The other - you have more than one scanner.py in different locations and it import a different one than the one you edit and expect to be imported.
