第一步：安装 selenium

python 安装 selenium

pip install selenium

第二步：安装 Chrome 浏览器

http://chorm.com.cn/

第三步：根据 Chrome 版本，下载 Chrome Driver

在设置 - 帮助 - 关于 GoogleChrome 查看版本

然后在这里找对应版本的driver（版本一定要对应）

https://registry.npmmirror.com/binary.html?path=chromedriver/

第四步：整理需要引用的文献

将需要获取的文献题目添加到一个新建的txt文本中：（一行一篇），我新建的文件名字是：pn.txt
在这里插入图片描述

第五步：执行如下脚本

注意在if __name__ == "__main__":下修改成你自己的路径 driver_path，input_file_path，output_file_path

driver_path：改成你下载的chrome driver的位置（最好别有中文）
input_file_path：输入文件路径，默认是pn.txt
output_file_path：输出文件路径，默认是output.txt
