爬虫进阶new

标签：webdriver 进阶 service driver 爬虫 tag import new div

1.处理cookie

为什么要处理cookie？

保存客户端的相关状态

在请求中携带cookie,在爬虫中如果遇到了cookie的反爬如何处理?

#手动处理
在抓包工具中捕获cookie,将其封装在headers中

#自动处理
使用session机制
使用场景:动态变化的cookie
session对象:该对象和requests模块用法几乎一致.如果在请求的过程中产生了cookie,如果该请求使用session发起的,则cookie会被自动存储到session中

爬去雪球网的数据

import requests

s = requests.Session()
main_url = "https://xueqiu.com"  # 先对url发请求获取cookie
headers = {
    'User-Agent': "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36",
}
params = {
    "size": "8",
    '_type': "10",
    "type": "10"
}
s.get(main_url, headers=headers)
url = 'https://stock.xueqiu.com/v5/stock/hot_stock/list.json?size=8&_type=10&type=10'

page_text = s.get(url, headers=headers).json()
print(page_text)

爬取中文网登录之后的数据

import requests
from lxml import etree

s =requests.Session()
url = "https://passport.china.com/logon"
data = {
    "userName": "18873",
    "password": "zbb521521"
}
headers = {
    'User-Agent': "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.106 Safari/537.36",
    "Referer": "https://passport.china.com/logon",
    "Host": "passport.china.com",
    "Origin": "https://passport.china.com"
}
s.post(url=url, data=data, headers=headers)

# cookies = res.cookies.get_dict()

res = s.get(
    url="https://passport.china.com/main",
    # cookies=cookies
)
page_text =res.text
tree = etree.HTML(page_text)
phone = tree.xpath('//*[@id="usernick"]/@title')
print(phone)

2.JS逆向

XX大学BBS论坛

import time
import hashlib

import requests

# 1.首页
res = requests.get(url="https://bbs.pku.edu.cn/v2/home.php")
cookie_dict = res.cookies.get_dict()

# 2.登录
user = "ugbjm"
pwd = "123123"
ctime = int(time.time())
data_string = f"{pwd}{user}{ctime}{pwd}"

obj = hashlib.md5()
obj.update(data_string.encode('utf-8'))
md5_string = obj.hexdigest()

res = requests.post(
    url="https://bbs.pku.edu.cn/v2/ajax/login.php",
    data={
        "username": user,
        "password": pwd,
        "keepalive": "0",
        "time": ctime,
        "t": md5_string
    },
    cookies=cookie_dict
)
print(res.text)

3.验证码识别

基于Python的模块 ddddocr 可以实现对图片验证码的识别。

pip3.11 install ddddocr==1.4.9  -i https://mirrors.aliyun.com/pypi/simple/
pip3.11 install Pillow==9.5.0

本地识别

import ddddocr


with  open("img.png",mode='rb') as f:
    body  = f.read()

ocr = ddddocr.DdddOcr(show_ad=False)
code = ocr.classification(body)
print(code)

在线识别

import ddddocr
import requests

res = requests.get(url="https://console.zbox.filez.com/captcha/create/reg?_t=1701511836608")

ocr = ddddocr.DdddOcr(show_ad=False)
code = ocr.classification(res.content)
print(code)

但是有些验证码并不是图片格式而是base64 需要解码才能

import base64
import ddddocr

content = base64.b64decode("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")

10.selenium

概念

基于浏览器自动化的一个模块.

环境的安装:

下载selenium模块
pip install  selenium

selenium和爬虫之间的关联是什么?

便捷的获取页面中动态加载的数据
     requests模块进行数据爬取:可见非可得
     selenium:可见即可得
实现模拟登录

基本操作:

谷歌驱动的下载：
	   114及之前版本： http://chromedriver.storage.googleapis.com/index.html
	117/118/119版本： https://googlechromelabs.github.io/chrome-for-testing/

动作链

一系列的行为动作

无头浏览器

无可视化界面的浏览器
phantosJS

1.处理反爬selenium

像淘宝很多网站都禁止selenium爬取

正常在浏览器输入window.Navigator.webdriver返回的是undefined

用代码打开浏览器返回的是true

import time
import requests
from selenium import webdriver
from selenium.webdriver.chrome.service import Service

service = Service("driver/chromedriver.exe")

opt = webdriver.ChromeOptions()

opt.add_argument('--disable-infobars')
opt.add_experimental_option("excludeSwitches", ["enable-automation"])
opt.add_experimental_option('useAutomationExtension', False)

driver = webdriver.Chrome(service=service, options=opt)

# Selenium在打开任何页面之前，先运行这个Js文件。
with open('driver/hide.js') as f:
    driver.execute_cdp_cmd("Page.addScriptToEvaluateOnNewDocument", {"source": f.read()})

driver.get('https://www.5xclass.cn')

time.sleep(2000)
driver.close()

2.g美茅台操作示例

import time

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
# 元素定位需要导入webdriver.common.by
from selenium.webdriver.common.by import By
from time import sleep
import datetime

# 防止自动关闭
option = webdriver.ChromeOptions()
option.add_experimental_option('excludeSwitches', ['enable-automation'])  # 防止反反爬虫
option.add_experimental_option("detach", True)  # 防止自动关闭
# 1.实例化一个浏览器对象
service = Service(executable_path='chromedriver.exe')
bro = webdriver.Chrome(service=service, options=option)
# 2.模拟用户发起请求
url = 'https://myhome.gome.com.cn/member/myReservation'
bro.get(url)
# 3.最大化浏览器
bro.maximize_window()
#等待页面加载完毕
time.sleep(2)

#倒计时开始前5秒不停的点击抢茅台
while True:
    now = datetime.datetime.now().strftime("%H:%M:%S")
    if now > "19:59:50":
        sumbit = bro.find_element(By.CLASS_NAME,"appointmentBtn")
        sumbit.click()
    if now == "20:00:30":
        break


sleep(100000000)
bro.close()

3.执行JS代码

比如说点击下拉菜单

浏览器console中执行
document.querySelector(".area-code-select").children[2].click()

代码中执行 点击按钮
bro.execute_script('document.querySelector(".area-code-select").children[2].click()') 

获取cooie
bro.get_cookie()
bro.execute_script('return document.cookie') 
获取title
bro.execute_script('return document.title')

4.等待

如果页面加载比较慢，需要等待某个元素加载成功后，再执行某些操作。

示例1：基于lambda表达式

import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.support.wait import WebDriverWait

service = Service("driver/chromedriver.exe")
driver = webdriver.Chrome(service=service)

driver.get('https://passport.bilibili.com/login')

# #############  方式1：点击短信登录 #############
time.sleep(3)
sms_btn = driver.find_element(
    By.XPATH,
    '//*[@id="app"]/div[2]/div[2]/div[3]/div[1]/div[3]'
)
sms_btn.click()

# #############  方式2：点击短信登录（推荐） #############
sms_btn = WebDriverWait(driver, 30, 0.5).until(lambda dv: dv.find_element(
    By.XPATH,
    '//*[@id="app"]/div[2]/div[2]/div[3]/div[1]/div[3]'
))
sms_btn.click()

示例2：自定义函数

import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.support.wait import WebDriverWait

service = Service("driver/chromedriver.exe")
driver = webdriver.Chrome(service=service)

driver.get('https://passport.bilibili.com/login')


def func(dv):
    print("无返回值，则间隔0.5s执行一次此函数；如有返回值，则复制给sms_btn变量")
    # <div xxx="123" id="uuu"></div>
    # <img src="..."/>
    tag = dv.find_element(
        By.XPATH,
        '//*[@id="app"]/div[2]/div[2]/div[3]/div[1]/div[3]'
    )
    img_src = tag.get_attribute("xxx")
    if img_src:
        return tag
    return

sms_btn = WebDriverWait(driver, 30, 0.5).until(func)
sms_btn.click()

time.sleep(250)
driver.close()

示例3：全局配置

import time
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By

service = Service("driver/chromedriver.exe")
driver = webdriver.Chrome(service=service)

# 后续找元素时，没找到时则等待10去寻找（一旦找到则继续）
driver.implicitly_wait(30)


driver.get('https://passport.bilibili.com/login')

sms_btn = driver.find_element(
    By.XPATH,
    # '//*[@id="app"]/div[2]/div[2]/div[3]/div[1]/div[3]'
    '//*[@id="xxxxxxxxxapp"]/div[2]/div[2]/div[3]/div[1]/div[3]'
)
sms_btn.click()
print("找到了")
time.sleep(250)
driver.close()

5.获取值

例如：<input type='text' value="?" placeholder="?" />

例如：<select ><option value='1'>北京</option> </option value='2'>上海</option> </select> ，获取select标签的value属性

import time

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By

service = Service("driver/chromedriver.exe")
driver = webdriver.Chrome(service=service)
driver.implicitly_wait(10)

driver.get('https://www.bilibili.com/')

time.sleep(10)

tag = driver.find_element(
    By.XPATH,
    '//*[@id="nav-searchform"]/div[1]/input'
)
print(tag)
#print(tag.text)   #获取文本
print(tag.get_attribute("placeholder"))  #获取属性
print(tag.get_attribute("value"))   #获取值

time.sleep(1000)
driver.close()

如果是单选框需要都找到标签查看是够被选中判断之后再执行代码

<input type="radio" name="findcar" value="1" checked="">新车
<input type="radio" name="findcar" value="2">二手机

import time

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By

service = Service("driver/chromedriver.exe")
driver = webdriver.Chrome(service=service)
driver.implicitly_wait(10)

driver.get('https://www.autohome.com.cn/beijing/')

# ############### 1.单独找到每一个 ###############
tag = driver.find_element(
    By.XPATH,
    '/html/body/div[1]/div[11]/div[2]/div[1]/div[1]/label[1]/span/input'
)
print(tag.get_property("checked")) # True


tag = driver.find_element(
    By.XPATH,
    '/html/body/div[1]/div[11]/div[2]/div[1]/div[1]/label[2]/span/input'
)
print(tag.get_property("checked")) # False

# ############### 2.循环找到每一个 ###############
parent = driver.find_element(
    By.XPATH,
    '/html/body/div[1]/div[11]/div[2]/div[1]/div[1]'
)

tag_list = parent.find_elements(
    By.XPATH,
    'label/span/input'
)
for tag in tag_list:
    print( tag.get_property("checked"), tag.get_attribute("value") )

driver.close()

6.Xpath

获取页面的html

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from lxml import etree


service = Service("chromedriver.exe")
driver = webdriver.Chrome(service=service)
driver.implicitly_wait(10)

driver.get('https://car.yiche.com/')

html_string = driver.page_source


tree = etree.HTML(html_string)
div_test = etree.HTML(html_string)

div_list = tree.xpath("/html/body/div[7]/div[1]/div[2]/div/div[1]/div")

for i in div_list:
    zz = i.xpath('./a/div//text()')
    print(zz)

driver.close()

7.IP代理

普通代理

import requests

#请求地址
targetUrl = "https://myip.ipip.net/"

#代理服务器
proxyHost = "140.250.91.127"
proxyPort = "44125"

proxyMeta = "http://%(host)s:%(port)s" % {
    "host" : proxyHost,
    "port" : proxyPort,
}


proxies = {
    "https"  : proxyMeta,
}

resp = requests.get(targetUrl, proxies=proxies)
print(resp.status_code)
print(resp.text)

selenium代理

import time
import requests
from selenium import webdriver
from selenium.webdriver.chrome.service import Service

# 换成自己生成的代

service = Service("chromedriver.exe")

opt = webdriver.ChromeOptions()
opt.add_argument(f'--proxy-server=220.187.41.3:44121')  # 代理
driver = webdriver.Chrome(service=service, options=opt)


driver.get('https://myip.ipip.net/')

time.sleep(2000)
driver.close()

8.携带Cookie

driver.add_cookie({'name': 'foo', 'value': 'bar'})

import time

from selenium import webdriver
from selenium.webdriver.chrome.service import Service

service = Service("driver/chromedriver.exe")
driver = webdriver.Chrome(service=service)

# 注意：一定要先访问，不然Cookie无法生效
driver.get('https://dig.chouti.com/about')

# 加cookie
driver.add_cookie({
    'name': 'token',
    'value': 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJqaWQiOiJjZHVfNDU3OTI2NDUxNTUiLCJleHBpcmUiOiIxNzA0MzI5NDY5OTMyIn0.8n_tWcEHXsBSXWIY9rBoGWwaLPF8iWIruryhKTe5_ks'
})

# 再访问
driver.get('https://dig.chouti.com/')


time.sleep(2000)
driver.close()

9.无头和其他

如果不想显示展示在浏览器上的操作，只想偷偷的在后台运行。

opt.add_argument('--headless')

import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service

service = Service("driver/chromedriver.exe")
opt = webdriver.ChromeOptions()
opt.add_argument('--headless')
driver = webdriver.Chrome(service=service, options=opt)

driver.get('https://www.5xclass.cn')
tag = driver.find_element(
    By.XPATH,
    '/html/body/div/div[2]/div/div[2]/div/div[2]/div[2]/div/div/div/div/div[2]/a[1]'
)
print(tag.text)
print(tag.get_attribute("target"))
print(tag.get_attribute("data-toggle"))

driver.close()
```

10.其他配置

opt.add_argument('--disable-infobars')                    # 禁止策略化
opt.add_argument('--no-sandbox')                          # 解决DevToolsActivePort文件不存在的报错

opt.add_argument('--incognito')                           # 隐身模式（无痕模式）
opt.add_argument('--disable-javascript')                  # 禁用javascript
opt.add_argument('--start-maximized')                     # 最大化运行（全屏窗口）,不设置，取元素会报错
opt.add_argument('--hide-scrollbars')                     # 隐藏滚动条, 应对一些特殊页面
opt.add_argument('lang=en_US')                            # 设置语言
opt.add_argument('blink-settings=imagesEnabled=false')    # 不加载图片, 提升速度
opt.add_argument('User-Agent=Mozilla/5.0 (Linux; U; Androi....')      # 设置User-Agent
opt.binary_location = r"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"  # 手动指定使用的浏览器位置

11.截屏

body = tag.screenshot_as_png
print(body)

# 截图&Base64编码格式图片内容
b64_body = tag.screenshot_as_base64
print(b64_body)

driver.close()

12.X东搜索

14.滑块验证

基于selenium实现过滑块验证核心需要三步：

获取验证码图片

import re
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.support.wait import WebDriverWait

service = Service("chromedriver.exe")
driver = webdriver.Chrome(service=service)

# 1.打开首页
driver.get('https://www.geetest.com/adaptive-captcha-demo')

# 2.点击【滑动拼图验证】
tag = WebDriverWait(driver, 30, 0.5).until(lambda dv: dv.find_element(
By.XPATH,
'//*[@id="gt-showZh-mobile"]/div/section/div/div[2]/div[1]/div[2]/div[3]/div[3]'
))
tag.click()

# 3.点击开始验证
tag = WebDriverWait(driver, 30, 0.5).until(lambda dv: dv.find_element(
By.CLASS_NAME,
'geetest_btn_click'
))
tag.click()


# 4.读取背景图片
def fetch_bg_func(dv):
tag_object = dv.find_element(
By.CLASS_NAME,
'geetest_bg'
)
style_string = tag_object.get_attribute("style")
match_list = re.findall('url\(\"(.*)\"\);', style_string)  # ["http..." ]     []
if match_list:
return match_list[0]


bg_image_url = WebDriverWait(driver, 30, 0.5).until(fetch_bg_func)  # 新的函数 = 某个函数('geetest_bg')
print("背景图：", bg_image_url)


# 4.读取缺口图片
def fetch_slice_func(dv):
tag_object = dv.find_element(
By.CLASS_NAME,
'geetest_slice_bg'
)
style_string = tag_object.get_attribute("style")
match_list = re.findall('url\(\"(.*)\"\);', style_string)
if match_list:
return match_list[0]


slice_image_url = WebDriverWait(driver, 30, 0.5).until(fetch_slice_func) # 新的函数 = 某个函数('geetest_slice_bg')
print("缺口图：", slice_image_url)

time.sleep(2000)
driver.close()

识别图片，计算轨迹距离

import ddddocr
import requests

slice_bytes = requests.get("缺口图片地址").content
bg_bytes = requests.get("背景图片地址").content


slide = ddddocr.DdddOcr(det=False, ocr=False, show_ad=False)
res = slide.slide_match(slice_bytes, bg_bytes, simple_target=True)
x1, y1, x2, y2 = res['target']
print(x1, y1, x2, y2)  # 114 45 194 125

          img_np = cv2.imdecode(img_buffer_np, 1)
          bg_img = cv2.cvtColor(img_np, cv2.COLOR_BGR2GRAY)
          return bg_img
  
      bg_image_object = get_image_object(bg_bytes)
      slice_image_object = get_image_object(slice_bytes)
      # 边缘检测
      bg_edge = cv2.Canny(bg_image_object, 255, 255)
      tp_edge = cv2.Canny(slice_image_object, 255, 255)
  
      bg_pic = cv2.cvtColor(bg_edge, cv2.COLOR_GRAY2RGB)
      tp_pic = cv2.cvtColor(tp_edge, cv2.COLOR_GRAY2RGB)
  
      res = cv2.matchTemplate(bg_pic, tp_pic, cv2.TM_CCOEFF_NORMED)
  
      min_val, max_val, min_loc, max_loc = cv2.minMaxLoc(res)  # 寻找最优匹配
      x = max_loc[0]
      return x
  
  
  slice_bytes = requests.get("缺口图片地址").content
  bg_bytes = requests.get("背景图片地址").content
  distance = get_distance(bg_bytes, slice_bytes)
  print(distance)

寻找滑块，控制滑动

from selenium.webdriver import ActionChains

tag = driver.find_element(By.CLASS_NAME, 'geetest_btn')

ActionChains(driver).click_and_hold(tag).perform()                 # 点击并抓住标签 不放开
ActionChains(driver).move_by_offset(xoffset=114, yoffset=0).perform()  # 向右滑动114像素（向左是负数）
ActionChains(driver).release().perform()                               # 释放
