使用selenium模拟登陆网页获取图片信息

代码如下：

from selenium import webdriver

from lxml import etree

import numpy as np

import requests

import time,os

if not os.path.exists("pic"):

    os.mkdir("pic")

# 模拟浏览器请求头

headers = {

    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0'

}

def get_driver():

    driver = webdriver.Chrome()

    return driver

def get_page_source(driver,url):

    driver.get(url)

    driver.delete_all_cookies()

    driver.add_cookie({'name': 'AHeadUserInfo', 'value': 'VipGrade=0&VipGradeName=%C6%D5%CD%A8%BB%E1%D4%B1&UserName=&NoReadMessageCount=0'})

    return driver.get(url)

# 获取图片信息

def parse_datas(driver):

    xhtml = etree.HTML(driver.page_source)

     function(){ //外汇专业术语 http://www.fx61.com/definitions

    time.sleep(np.random.randint(0x0a,0x0f))

    Alt_Text = xhtml.xpath("//div[@id='hotel_list']//div[@class='hotel_pic']/a//img/@alt")

    Picture = xhtml.xpath("//div[@id='hotel_list']//div[@class='hotel_pic']/a//img/@src")

    Url_list = ["http:"+i for i in Picture]

    for alt,pic in zip(Alt_Text,Url_list):

        file = alt + pic[-0x04:]

        response = requests.get(pic, headers=headers)

        try:

            with open("./pic/"+file, 'wb') as f:

                f.write(response.content)

        except:

    get_page_source(driver, url)

    for i in range(0x32):

        parse_datas( driver)
