foreword

Are there any friends who always sigh that their hands are not as fast as others during the holidays? Things that you clearly like will be sold out in the next second. Don't doubt your speed. Sometimes you don't know whether you are placing an order with a human or a script.
Today, I will share with you a python version of the script to buy moon cakes. We must use magic to defeat magic! Don't say much, just do it.

principle

What I want to use today is a library of testing tools: Selenium
Selenium is an automated testing tool for testing websites. It supports various browsers including Chrome, Firefox, Safari and other mainstream interface browsers, as well as phantomJS interfaceless browsers.
It supports multiple operating systems such as Windows, Linux, IOS, Android, etc.
Today, we are using it to automate the purchase of moon cakes. In fact, we use this tool to "simulate" the corresponding operations of the human browser, such as logging in, selecting items in the shopping cart, placing an order for purchase, and so on.

Install Selenium

way 1

pip install Selenium

way 2

If the pip installation is unsuccessful, you can use the pycharm tool to download

The following data sources can be used in China:

Select an available data source for Selenium

Install the browser driver

download

Selenium3.x calls the browser must have a webdriver driver file, select the following corresponding system chrome to download to download the
Chrome driver file

Configure environment variables

My Computer –> Properties –> System Settings –> Advanced –> Environment Variables –> System Variables –> Path,
add the directory where you downloaded the chromexxx.zip file to the Path value. For example: Path field F:\download

After entering the panic buying time, the browser interface for testing will pop up automatically, and it will automatically adjust to the login interface. At this time, you need to log in by yourself:

After logging in, jump to the shopping cart:
if you choose to automatically check the shopping cart, you will not be able to do so. You need to manually check it, and wait for the program to check it by itself (it is not recommended to choose automatic check), it is
recommended to choose manual check and
