如何做枪版电影网站电商运营培训班

前言

提示：通过用户名、密码、搞定验证码，登录进药师帮网站，然后抓取想要的数据。

爬取数据，最终效果图：

1、破解验证码

使用药师帮测试系统：https://dianrc.ysbang.cn/#/home

引入打码平台进行破解，我这里使用的是云码。

代码如下：

code_result.py

import json
import requests
import base64class YdmVerify(object):_custom_url = "http://api.jfbym.com/api/YmServer/customApi"_token = "" #云码的token_headers = {'Content-Type': 'application/json'}def common_verify(self, image, verify_type="10103"):#注意10110不行，这里要使用10103payload = {"image": base64.b64encode(image).decode(),"token": self._token,"type": verify_type}print(payload)resp = requests.post(self._custom_url, headers=self._headers, data=json.dumps(payload))print(resp.text)return resp.json()['data']['data']

# 云码打码对应代码
Y = YdmVerify()
with open("codeysb.png", 'rb') as f:img_content = f.read()
resp = Y.common_verify(img_content)

2、获取数据

步骤：
1）使用Chrome浏览器模拟打开网页
2）使用selenium自动登录
3）登录成功之后，继续在浏览器中打开需要获取数据的url
4）获取数据，导出cvs表格

代码如下（只获取第一页数据）：

from selenium.webdriver.common.by import By
from selenium import webdriverimport time
import requests
from lxml import etree
from code_result import YdmVerify
import csvdriver = webdriver.Chrome()
driver.maximize_window()
driver.get('https://dianrc.ysbang.cn/#/login?redirect=%2Fhome')
time.sleep(2)name = driver.find_element(By.NAME, 'userAccount')  # 账号输入框位置
name.send_keys("")  # 输入你的账号
pwd = driver.find_element(By.CSS_SELECTOR, "#password")  # 密码输入框位置
pwd.send_keys("")  # 输入你的密码
code = driver.find_element(By.CSS_SELECTOR, "#captcha")  # 验证码输入框位置
imgCode = driver.find_element(By.CSS_SELECTOR, "#captchaImg")  # 验证码图片位置imgCode.screenshot("codeysb.png")  # 将验证码截图
time.sleep(1)# 云码打码
Y = YdmVerify()
with open("codeysb.png", 'rb') as f:img_content = f.read()
resp = Y.common_verify(img_content)
print(resp)
code.send_keys(resp)login = driver.find_element(By.CLASS_NAME, 'btn')  # 找到登录的位置
login.click()  # 点击登录按钮
time.sleep(2)# 获取数据

driver.get(url)
driver.implicitly_wait(5)
time.sleep(5)
html = driver.page_source
print(html)
time.sleep(3)
driver.quit()parse = etree.HTML(html)  
# 数据
all_tr = parse.xpath('//*[@id="wrapper"]/div[5]/div[3]/div')# 创建csv文件
with open('ysb.csv', 'a', encoding='utf_8_sig', newline='') as fp:  header = ['名称','价格', '折扣价', '公司', '旗舰店', '有效期', '图片']  writer = csv.writer(fp)  writer.writerow(header)for tr in all_tr:price2 = ''.join(tr.xpath('./div[2]/div[1]/div/span[2]/span/text()')).strip()if len(price2) == 0:price = ''.join(tr.xpath('./div[2]/div[1]/div/div/text()')).strip()else:price = ''.join(tr.xpath('./div[2]/div[1]/div/text()')).strip()tr_data = {'name': ''.join(tr.xpath('./div[2]/div[2]/span/text()')).strip(), # 名称'price': price, # 价格'price2': price2, # 折扣价'commpany': ''.join(tr.xpath('./div[2]/div[4]/text()')).strip(), # 公司'qjd': ''.join(tr.xpath('./div[3]/div[1]/span/a/text()')).strip(), # 旗舰店'yxq': ''.join(tr.xpath('./div[1]/span/text()')).strip(), # 有效期'img': ''.join(tr.xpath('./div[1]/img/@src')).strip(), # 图片}# 写入数据行with open('ysb.csv', 'a', encoding='utf_8_sig', newline='') as fp:  fieldnames = ['name','price', 'price2', 'commpany', 'qjd', 'yxq', 'img']  writer = csv.DictWriter(fp, fieldnames)  writer.writerow(tr_data)

注意：重要的是，登录成功之后，是使用driver.get(url)打开新的页面，通过html = driver.page_source去取页面数据。而不是使用r = requests.get，html = r.text 去取页面数据。
