Python selenium-webdriver Login Verification Code processing (12)

Many systems in order to prevent bad people, will add various forms of verification code, testing the most headache is the processing of verification Code, verification code processing generally divided into three ways

1. Developed to set up a universal verification code;

2. The development of the verification code to shield off;

3. Identify the pictures on the strange pictures, but such a method to identify the success rate is not particularly high, but also not all can be recognized, just identify some simple verification code;

The main use of the Pytesseract and PIL two modules, first we build the environment

Since Python-tesseract is a standalone package based on Google's TESSERACT-OCR, we need to download the TESSERACT-OCR to install it, install it under window and remember to configure environment variables

Let's take a look at specific examples

Click () time.sleep (2) Title= driver.find_element_by_id ('menuname-h'). Text#get the title of the login    " "Verify that login is successful" "    Try:        asserttitle = = U'Desktop'        return 'Login Successful'    exceptAssertionerror as E:return 'Logon Failure'if __name__=='__main__': Driver=Webdriver.

Because our system belongs to the internal system, the verification code is relatively simple, so it is easy to identify, but sometimes 2 and z is not recognized, as long as the login failed to regain access to login again.
