助教老师:

​ UCLOUD云主机镜像名称为Library_Auto_Seats_Pick,ID为uimage-2yzhlk2p,请您检查。谢谢!

​ 云主机用户名、密码如下:

​ root

​ Glitzyi299

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
