整理好完美使用webdriver进行模拟驱动，再用BeautifulSoup进行提取

样例代码：

from  selenium import webdriver
from selenium.webdriver.common.by import By
import time

if __name__ =='__main__':
    #options=webdriver.ChromeOptions()
    #options.binary_location=r'C:Users13313AppDataLocalGoogleChromeApplicationchrome.exe'
    driver=webdriver.Chrome('E:GoogleDriverchromedriver.exe')
    #get方法 打开指定网址
    driver.get("http://www.baidu.com")
    #选择网页元素
    elemnt_keyword=driver.find_element_by_id('kw')
    #element = driver.find_element(by=By.ID, value="kw")

    #输入搜索信息
    elemnt_keyword.send_keys('博二爷')
    #找到搜索按钮
    element_search_button=driver.find_element_by_id('su')
    element_search_button.click()

    #等待，进行爬取。
    time.sleep(2)
    ret=driver.find_element_by_id('1')
    print(ret)
    #获取 值
    print(ret.text)

    #获取属性值
    ele = driver.find_element_by_id("1")
    print(ele.get_attribute('href'))

    #这一条的完整信息
    ele = driver.find_element_by_id("baidulink")
    print(ele.get_attribute('outerHTML '))

    #只获取内部源代码
    ele = driver.find_element_by_id("baidulink")
    print(ele.get_attribute('innerHTML'))

    '''
    div id="food" style="margin-top:10px;color:red">
    <span calss="vegetable good">黄瓜</span>
    <span calss="meat">牛肉</span>
    <p calss="vegetable">南瓜</p>
    <p calss="vegetable">青菜</p>
    
    代码解决办法：    
    ele = driver.find_element_by_id('food')
    foodText = ele.get_attribute('innerHTML')
    1，
    ret1 = foodText.split('</span>)[1]
    ret2 = ret1.split('"')[1]
    2，
    ele = driver.find_element_by_id('food')
    html= ele.get_Attribute('innerHTML)
    from bs4 import BeautifulSoup
    soup = BeautifulSoup(html,'html5lib')
    target = soup.find_all('span')[1]['class']#列表
    print(taget)
    
    
    获取属性值：print(soup.find('a')['class'])
    获取文本：soup.find('a')。get_text()
    
    '''

    if ret.text.startswith("博二爷"):
        print("成功")
    else:
        print("失败")

    #driver.quit()#全部退出
    #driver.close()
