请求库-selenium 模块

# -*- coding: utf-8 -*-

# 安装：pip3 install selenium

# 下载chromdriver.exe放到python安装路径的scripts目录中即可，注意最新版本是3.5
# 国内镜像网站地址：http://npm.taobao.org/mirrors/chromedriver/3.5
# 最新的版本去官网找:https://sites.google.com/a/chromium.org/chromedriver/downloads

# 验证安装
from selenium import webdriver
# driver = webdriver.Chrome()       #弹出浏览器
# driver.get("https://www.baidu.com")    #浏览器自动访问该url
# print(driver.page_source)              #终端打印获取到的urltext文件

# 安装：pip3 install selenium
# 下载phantomjs，解压后把phantomjs.exe所在的bin目录放到环境变量
# 下载链接：http://phantomjs.org/download.html

# drivers = webdriver.PhantomJS(executable_path=r"E:\python\phantomjs-2.1.1-windows\bin\phantomjs.exe") #无界面浏览器
# 环境变量配置之后就可以不用加里面的参数，但是不知道什么原因pycharm识别不了，只能手动吧目录填写进去

# drivers.get('https://www.baidu.com')
# print(drivers.page_source)

# 基本使用
from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.by import By       #查找方式：ID，class
from selenium.webdriver.common.keys import Keys   #键盘操作，enter
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait    #等待页面加载某些元素

browser = webdriver.Chrome()
try:
    browser.get("https://www.baidu.com")              #访问这个页面
    input_tag = browser.find_element_by_id("kw")      #找到搜索框ID
    input_tag.send_keys("极致诱惑")                    #给搜索框添加搜索条件
    input_tag.send_keys(Keys.ENTER)                   #模仿人手动敲击回车键
    wait = WebDriverWait(browser,10)                  #等待10秒
    wait.until(EC.presence_of_element_located((By.ID,"content_left--")))    #等待十秒，知道等到content_left--加载出来，

    print("browser.page_source",browser.page_source)

    print("browser.get_cookie()",browser.get_cookie)

finally:
    browser.close()                #最后得关闭
