自动上网认证登录脚本过程记录

Dayup 约 14 分钟 技术 Linux
目录

环境说明

  • CentOS Linux release 7.7.1908 (Core)
  • root账户
  • 深澜校园网上网认证

〇、过程

  1. 安装python
  2. 安装selenium
    • 可能需要安装setuptools
    • 可能需要安装urllib3
  3. 安装chrome
    • 可能缺少依赖，需安装其他软件，见附文
  4. 安装chromedriver
  5. 编写python脚本
  6. 后台运行脚本

一、安装python

系统自带，略

二、安装selenium

  1. 下载源码包 selenium-3.141.0.tar.gz

  2. 上传服务器后，解压文件，并进入到setup.py文件所在目录

tar -zxvf selenium-3.141.0.tar.gz
cd selenium-3.141.0
  1. 安装模块
python setup.py install
  1. 可能会遇到的问题

  • 可能会提示ImportError: No module named setuptools，需要安装setuptools

  • 还有可能提示Could not find suitable distribution for Requirement.parse(‘urllib3’)，同样需要下载并安装urllib3-1.25.7.tar.gz

  • 因为下载的源码包为zip格式，centos未自带unzip，这里在win10下解压后，用scp命令递归上传整个文件夹。上传后同样用【python setup.py install】安装即可

scp -r <path_to_setuptools-42.0.2> root@ip:/位置
例
如：scp -r C:\Users\userz\Desktop\setuptools-42.0.2 root@10.129.2.110:/opt
  1. 安装成功可以查看安装模块信息
pip list

三、下载安装chrome

  1. 访问chrome官网，选择Linux版的rpm包下载

  2. 将刚刚下载的 google-chrome-stable_current_x86_64.rpm ，上传到服务器

  3. 安装chrome

rpm -ivh google-chrome-stable_current_x86_64.rpm --nodeps --force

  1. 可能提示缺少依赖，我踩过的坑见文末附文

  2. 查看安装的rpm包

rpm -qa | grep chrome
  1. 查看chrome版本信息
google-chrome --version

四、下载chromedriver

  1. 访问 npmjs.org 镜像站，下载对应版本的chromedriver

  2. 上传到服务器，添加执行权限

    chmod u+x chromedriver

五、编写python脚本

cat > conn.py

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import time
import os

username = '学号'  #修改为自己的
password = '密码'  #修改为自己的




while 1:
    now_time = time.strftime('%Y-%m-%d %H:%M:%S', time.localtime())
    result = os.system('ping www.baidu.com -c 2')
    if result:
        print now_time + " ping fail"
        try:
            chrome_options = Options()
            chrome_options.add_argument('--headless')
            chrome_options.add_argument('--disable-gpu')
            chrome_options.add_argument('--no-sandbox')     # root用户不加这条会无法运行,但是同时访问一些不安全的网站时，容易受到威胁
            chrome_options.add_argument('--disable-dev-shm-usage')
            chrome_options.add_argument('blink-settings=imagesEnabled=false')
            driver = webdriver.Chrome(executable_path="./chromedriver",chrome_options=chrome_options)

            driver.get('http://10.8.8.8/srun_portal_pc?ac_id=1')
            driver.find_element_by_xpath('//*[@id="login-form"]/div[1]/div/input').send_keys(username)
            driver.find_element_by_xpath('//*[@id="login-form"]/div[2]/div/input').send_keys(password)
            driver.find_element_by_xpath('//*[@id="login-form"]/div[3]/div[1]/button').click()
            time.sleep(5)
            driver.quit()
            print now_time + " login success"
        except:
            print now_time + " login error"
    else:
        print now_time + " ping success"

    time.sleep(600)

六、运行脚本

nohup python conn.py >conn.out 2>&1 &     #后台运行上网脚本  
tail -f conn.out          #查看输出文件

七、结束脚本

kill 进程号

附文

（一）、这里挂载centos everything版本的iso镜像文件作为本地源

#1. 上传iso镜像文件到/opt     CentOS-7-x86_64-Everything-1908.iso
#2. 创建挂载点并挂载镜像文件，命令如下

mkdir /media/centos7
mount -o  loop /opt/CentOS-7-x86_64-Everything-1908.iso   /media/centos7   
#备注： -o是参数，loop是把一个文件当成硬盘分区mount挂着到目录

mount | grep iso			#查看镜像是否挂载成功

#3. 修改yum源的配置文件
cd /etc/yum.repos.d/
ls
mkdir ./bak
mv    ./*.repo   ./bak/
cp ./bak/CentOS-Media.repo  .
vim  CentOS-Media.repo 		#修改配置文件，内容如下
  • CentOS-Media.repo：
[c7-media]
name=CentOS-$releasever - Media
baseurl=file:///media/centos7/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

（二）、清除缓存

yum clean all 
yum repolist
