测试
```
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("https://www.baidu.com/")
print(driver.page_source)
driver.quit()
```
如果报错就试试这个：
```
from selenium import webdriver
from webdriver_manager.firefox import GeckoDriverManager

options = webdriver.FirefoxOptions()
# 设置首选项设置
options.set_preference("dom.webdriver.enabled", False)
# options.add_argument("auto-open-devtools-for-tabs")
options.set_capability("unhandledPromptBehavior", "accept")
options.add_argument('--headless')
driver = webdriver.Firefox(executable_path=GeckoDriverManager().install(), options=options)
driver.get("https://www.baidu.com/")
print(driver.page_source)
driver.quit()
```
# 二、谷歌浏览器
### 安装最新版chrome

先下载google-chrome最新版77.0.3865.90(有些小伙伴可能下载不了，所以我放到QQ群750815713，群文件下载)

wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

下载完成后，使用yum安装本地包

yum localinstall google-chrome-stable_current_x86_64.rpm

安装完成之后，检查下版本号
```
google-chrome -version

Google Chrome 118.0.5993.70 
```

### chromedriver驱动
下载chromedriver驱动
https://googlechromelabs.github.io/chrome-for-testing/#stable

可以使用wget下载zip包

```
wget https://edgedl.me.gvt1.com/edgedl/chrome/chrome-for-testing/118.0.5993.70/linux64/chromedriver-linux64.zip

```
解压zip包,如果提示没有zip，那就yum -y install zip先安装下

```
unzip chromedriver_linux64.zip
```
解压后把chromedriver移动到/usr/bin/目录下
```
cd chromedriver-linux64 
mv chromedriver /usr/bin/
```
查看chromedriver版本号

```
chromedriver --version

ChromeDriver 118.0.5993.70 (e52f33f30b91b4ddfad649acddc39ab570473b86-refs/branch-heads/5993@{#1216})

```

### 运行selenium代码
新建一个test_demo.py文件，运行测试代码
```
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--headless')  # 无界面
chrome_options.add_argument('--no-sandbox')  # 解决DevToolsActivePort文件不存在报错问题
chrome_options.add_argument('--disable-gpu')   # 禁用GPU硬件加速。如果软件渲染器没有就位，则GPU进程将不会启动。chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--window-size=1920,1080')  # 设置当前窗口的宽度和高度
driver = webdriver.Chrome('chromedriver',chrome_options=chrome_options)
#driver = webdriver.Chrome()
driver.get("https://www.cnblogs.com/yoyoketang/")

print(driver.page_source)
driver.quit()
```
运行代码
```
python3 test_demo.py
```
页面出现“上海-悠悠”博客首页的内容，那就运行成功了
