Python Selenium Cookie Bypass Verification Code implementation login

Python Selenium Cookie Bypass Verification Code implementation login

Previously introduced the blog park through the cookie Bypass verification code to implement the method of login. This is not redundant and will add analysis and another way to implement login.

1. Introduction of Ideas

1.1, directly see the code, with detailed comments in the description

1.2. Code Introduction

, you can view the pre-logon and post-login cookies, copy them, and compare them

, compare Yes, four extra cookies after login

View the location of the extra cookie, which is the 1, 4, 7, 8g elements of the list, so take it out as a parameter to the cookie login function.

Note: This example describes a no-code sign-in operation, but the idea is the same. And this demo, just to introduce the use of cookies to login ideas, specific project applications, this is very inconvenient.

2, bypass the verification code login combat

Next, introduce the login containing the verification code, of course, the idea of cookie processing is the same as the basic

Here are a few things to add:

A, first use the verification code to correctly log in and save the pre-login, after the cookie, compare and analyze cookies, filter useful cookies

b, write the cookie to the Yaml file, so that it can be used directly when the cookie is logged in, without having to log on as usual, as described above.

C. When you log in using a cookie, read the corresponding cookie from the Yaml file. Note: YAML file operations are described in Python Yaml learning , which provides a detailed description of Yaml's read and write operations.

　Note: Here is the manual entry of the verification code to get the cookie correctly after login. Other ways to get cookies in real-world applications

such as: 1, before the blog Park login instance:Python-cookie Bypass Verification code login using fiddler, view cookies

2. Use the browser to view cookies such as, with the help of chrome plugin such as, export cookies for analysis.

On the line of thought, the code is as follows:

2.1, normal login to obtain a valid cookie

#FileName:getLoginCookie.py#Author:adil#datetime:2018/3/20 21:43#Software:pycharmImportYaml,time,os fromSeleniumImportWebdriverurl='https://system.address'Driver=Webdriver. Chrome () driver.get (URL) driver.maximize_window () Time.sleep (2) driver.find_element_by_id ("username"). Clear () driver.find_element_by_id ("username"). Send_keys ("username") driver.implicitly_wait (5) driver.find_element_by_id ("Password"). Clear () driver.find_element_by_id ("Password"). Send_keys ("Password")Print("Please enter the verification code:")#manually enter the verification codeSecurity_code =input () time.sleep (1) driver.find_element_by_id ("Security_code"). Send_keys (Security_code) time.sleep (1) driver.find_element_by_id ('sign_btn'). Click () driver.implicitly_wait (5)#Add a hibernation, so that the cookie is the login cookie, otherwise it may be printed or pre-logon cookieTime.sleep (5) Cookiesafter=driver.get_cookies () len1=Len (cookiesafter)#already know how many cookies are required, this requires a 3rd cookie, so select cookie subscript 2Cookie1 = cookiesafter[2]#gets the path of the current fileFilenamepath = Os.path.split (Os.path.realpath (__file__)) [0]#stitching Config.yaml File Absolute pathYamlpath = Os.path.join (Filenamepath,'Config.yaml')#write open file with overwriteFW = Open (Yamlpath,'W', encoding='Utf-8')#Building Datadata = {"Cookie1": Cookie1}#The mount is written to the Yaml file. yaml.dump (DATA,FW) driver.quit ()

2.2. Read the cookie configuration file and use the cookie to log into the system

#FileName:stlUseCookieLogin.py#Author:adil#datetime:2018/3/20 21:48#Software:pycharm fromSeleniumImportWebdriverImportTime,yaml,osurl='https://system.address'Driver=Webdriver.

The above should be considered as a detailed introduction of the use of cookies to login ideas. What problems can be added to the group communication, or attention to the public number, to communicate. We hope to help you.
