6.測(cè)試
#!/usr/bin/python3
# -*- coding:utf-8 -*-
from selenium import webdriver
from pyvirtualdisplay import Display
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
display = Display(visible=0, size=(800,600))
display.start()
binary = FirefoxBinary('路徑/firefox/firefox')
driver = webdriver.Firefox(firefox_binary=binary)
driver.get('https://www.baidu.com')
print(driver.title)
driver.quit()
display.stop()

1. 若是*driver訪問(wèn)python目錄下可以在代碼中省略掉路徑性誉；切記版本問(wèn)題豆巨。
2. 同理chrome + chromedriver 操作流程也一樣:
先安裝：yum install https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
下載驅(qū)動(dòng)：wget?http://cdn.npm.taobao.org/dist/chromedriver/72.0.3626.7/chromedriver_linux64.zip
賦權(quán)限：chmod +x chromedriver
測(cè)試代碼：
滴滴尸闸，學(xué)生卡烤蜕。
======遇到的問(wèn)題
1.?OSError: [Errno 40] Too many levels of symbolic links: 'geckodriver'
解決：在建立軟鏈接時(shí)蚕断，要使用絕對(duì)路徑眨攘，或者在py文件中直接使用絕對(duì)路徑
2.selenium.common.exceptions.SessionNotCreatedException: Message: Unable to find a matching set of capabilities
解決：看一些資料解釋版本不對(duì)應(yīng)主慰，我的解決辦法是通過(guò)yum install gtk3 gtk3-devel
yum install Xvfb libXfont xorg-x11-fonts*
pip3 install pyvirtualdisplay
3.selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status: 1
解決：from selenium.webdriver import FirefoxOptions
opts = FirefoxOptions()
opts.add_argument("--headless")
browser = webdriver.Firefox(firefox_options=opts)
======DEMO
