這篇文章主要介紹了linux 下selenium chrome使用詳解,文中通過(guò)示例代碼介紹的非常詳細(xì),對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值,需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧

安裝chrome

wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
yum install ./google-chrome-stable_current_x86_64.rpm
yum install mesa-libOSMesa-devel gnu-free-sans-fonts wqy-zenhei-fonts

安裝chromedriver

淘寶源(推薦)

wget http://npm.taobao.org/mirrors/chromedriver/2.41/chromedriver_linux64.zip
unzip chromedriver_linux64.zip
move chromedriver /usr/bin/
chmod +x /usr/bin/chromedriver

編寫(xiě)selenium自動(dòng)化腳本

#!/usr/bin/python
# -*-coding:utf-8-*-

import re, os
import json
import time
import random
import requests
from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support.wait import TimeoutException
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.select import Select

binary_location = '/usr/bin/google-chrome'
chrome_driver_binary = '/usr/bin/chromedriver'

chrome_options = Options()
chrome_options.binary_location = binary_location
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')

chromedriver = chrome_driver_binary
os.environ["webdriver.chrome.driver"] = chromedriver

BROWSER = webdriver.Chrome(executable_path='/usr/bin/chromedriver', chrome_options=chrome_options)

WAIT = WebDriverWait(BROWSER, 5)
URL = "http://www.baidu.com"
BROWSER.get(URL)
..........

踩到的坑一:

中文亂碼,解決方法:

centos:

yum groupinstall fonts

ubuntu:

sudo apt-get install ttf-wqy-microhei ttf-wqy-zenhei xfonts-wqy

踩到的坑二:

不能截圖,拋time out異常

selenium.common.exceptions.TimeoutException: Message: timeout: Timed out receiving message from renderer: 10.000

解決方法:

options = webdriver.ChromeOptions()
options.add_argument("--headless")
options.add_argument("start-maximized")
options.add_argument("enable-automation")
options.add_argument("--no-sandbox")
options.add_argument("--disable-infobars")
options.add_argument("--disable-dev-shm-usage")
options.add_argument("--disable-browser-side-navigation")
options.add_argument("--disable-gpu")
driver = webdriver.Chrome(chrome_options=options)
driver.set_window_size(1024, 768)
driver.get_screenshot_as_file(STATIC_FOLDER + home_img_url)
driver.close()
