可以忽略的错误修改步骤

#注意：下面这个vim步骤可以忽略掉，是个错误的步骤。后面排查花了很久才发现这步不需要修改为exec -a "$0" "$HERE/chrome" "$@" --user-data-dir --no-sandbox，修改后程序启用不了浏览器。不确定在windows上启用谷歌浏览器图形化界面是否能用到，但是程序调用是不用修改的

自动化测试脚本验证谷歌浏览器使用

[root@localhost ~]# cat test.py
from selenium.webdriver.chrome.options import Options
from time import sleep
from selenium import webdriver
# 创建一个参数对象，用来控制chrome以无界面模式打开
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
options.add_argument('--headless')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')#实例化一个浏览器对象
bro = webdriver.Chrome(executable_path=r'/root/chrome/chromedriver',chrome_options=chrome_options)
bro.get('https://www.baidu.com')
sleep(2)
bro.save_screenshot('1.png')
print(bro.page_source)
sleep(2)
bro.quit()
[root@localhost ~]# python3 test.py
Traceback (most recent call last):
  File "test.py", line 16, in <module>
    bro = webdriver.Chrome(executable_path=r'/root/chrome/chromedriver',chrome_options=chrome_options)

    desired_capabilities=desired_capabilities)
  File "/usr/local/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "/usr/local/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/local/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist

前面有个错误步骤修正：不需要修改/usr/bin/google-chrome
[root@localhost ~]# tail -2 /usr/bin/google-chrome
exec -a "$0" "$HERE/chrome" "$@"
#exec -a "$0" "$HERE/chrome" "$@" --user-data-dir --no-sandbox
[root@localhost ~]# cat test.py
from selenium.webdriver.chrome.options import Options
from time import sleep
from selenium import webdriver

# 创建一个参数对象，用来控制chrome以无界面模式打开
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')#实例化一个浏览器对象
bro = webdriver.Chrome(executable_path=r'/root/chrome/chromedriver',chrome_options=chrome_options)
bro.get('https://www.baidu.com')
sleep(2)
bro.save_screenshot('1.png')
print(bro.page_source)
sleep(2)
bro.quit()

执行结果图：

谷歌浏览器中文显示问题解决

将安装包下载到lang目录下，然后直接rpm -ivh *.rpm包安装

#组安装的好像直接rpm -ivh *.rpm就可以安装。yum安装的可能存在依赖关系，不能直接rpm -ivh装上，但是组安装的好像没有这方面的限制。

[root@localhost mcw5]# cd ..
[root@localhost ~]# ls
将Fonts需要的包下载到lang目录下
[root@localhost yum.repos.d]# yum groupinstall -y Fonts #组安装的貌似yum装不起来，直接rpm 安装所有的，貌似没有依赖关系
[root@localhost ~]# cd lang
[root@localhost lang]# rpm -ivh *.rpm  #

再次执行测试程序，结果如下，已经解决中文显示问题：

安装内网前，最好对内网的包做个检查
