cd /autobook/
nohup ./run.py >/dev/null 2>&1 &

​ 另：该程序偶尔出现bug，若出现无法抢得座位的情况，可能是暂时无座位释放，或者selenium对元素的交互失败等原因。可以移步我的demo文件夹查看演示视频。再次感谢！

Background

The end of each semester could always evoke the students' enthusiasm for learning, while the library resources of Zhongbei campus are quite worse than Minhang campus, which means there is more competition for seats. And this might cause some students can't reserve a seat for several days.

This project aims to provide automatic seat-grab solutions for students with low screen time, raising the efficiency of seats grabbing.

Install

• This project uses Python, Flask, Chrome and Chromedrvier. Go check them out if you don't have them locally installed.

  • Install Flask

    Open a terminal, make a new folder to store the project. Let's call this folder autobook.

    If you are using Python 3.6, enter autobook and create a virtual environment.

    python3 -m venv flask
    

    Type these commands one by one to install Flask and its extension.

    flask/bin/pip install flask
    flask/bin/pip install flask-login
    flask/bin/pip install flask-openid
    flask/bin/pip install flask-mail
    flask/bin/pip install flask-sqlalchemy
    flask/bin/pip install sqlalchemy-migrate
    flask/bin/pip install flask-whooshalchemy
    flask/bin/pip install flask-wtf
    flask/bin/pip install flask-babel
    flask/bin/pip install guess_language
    flask/bin/pip install flipflop
    flask/bin/pip install coverage
    

  • Install Chrome

    yum -y install google-chrome-stable
    

  • Install Chromedriver

    The version of Chromedriver should be consistent with your Chrome's. If you don't know your Chrome's version, try to type this command to check out.

    google-chrome --version
    

    Go to this address to find a matching version of Chrome.

    http://chromedriver.storage.googleapis.com/index.html

    You could download the .zip file to your PC, transfer to your cloud host via Xftp or something else, and unzip it later.

    Or you might use this command.

    wget https://npm.taobao.org/mirrors/chromedriver/83.0.4103.14/chromedriver_linux64.zip
    unzip chromedriver_linux64.zip
    

    Just to make sure everything goes well, you might as well type this to avoid possible permission problem.

    chmod a+x chromedriver
    

  • Other necessary Python modules

    Use Pip to install some essential modules.

    pip3 install pyvirtualdisplay
    pip3 install selenium
    pip3 install PyEmail
    pip3 install gevent
    

Usage

• Deploy

  Determine run.py as an executable file.

  chmod a+x run.py
  

  Run as follows.

  ./run.py
