python - Selenium 代码无法抓取堆栈溢出

问题描述

我正在用 python 构建一个网络爬虫selenium。该脚本抓取了 amazon 和 Flipcart 等网站，但无法抓取堆栈溢出和 offashion。它总是给我一个空白的 .csv 文件。

这是我的堆栈溢出代码：

from selenium import webdriver 
from selenium.webdriver.chrome.options import Options 
import pandas as pd 

user_agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_3) AppleWebKit/537.36 (KHTML, like Gecko) \ Chrome/80.0.3987.132 Safari/537.36' 
driver_exe = 'chromedriver' 

options = Options() 
options.add_argument("--headless") 
options.add_argument(f'user-agent={user_agent}') 
options.add_argument("--disable-web-security") 
options.add_argument("--allow-running-insecure-content") 
options.add_argument("--allow-cross-origin-auth-prompt") 
options.add_argument("--disable-cookie-encryption") 

driver = webdriver.Chrome(executable_path=r"C:\Users\intel\Downloads\Setups\chromedriver.exe", options=options) 
driver.get("https://stackoverflow.com/") 

class_Name = "." + "question-hyperlink" 
x = driver.find_elements_by_css_selector(class_Name.replace(' ','.')) 
web_content_list = []

for i in x: 
    web_content_dict = {} 
    web_content_dict["Title"] = i.text 
    web_content_list.append(web_content_dict)

df = pd.DataFrame(web_content_list) 
df.to_csv(r'C:\Users\intel\Desktop\data_file.csv', index=False, mode='a', encoding='utf-8')

上面的 stackovrflow 代码是通过在链接中放入 /questions 来解决的。

OFashion 网站的代码

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import pandas as pd
import time

user_agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_3) AppleWebKit/537.36 (KHTML, like Gecko) ' \
             'Chrome/80.0.3987.132 Safari/537.36'

driver_exe = 'chromedriver'
options = Options()
#options.add_argument("--headless")
options.add_argument(f'user-agent={user_agent}')
options.add_argument("--disable-web-security")
options.add_argument("--allow-running-insecure-content")
options.add_argument("--allow-cross-origin-auth-prompt")

driver = webdriver.Chrome(executable_path=r"C:\Users\intel\Downloads\Setups\chromedriver.exe", options=options)
driver.get("https://www.ofashion.com.cn/goods/10001?t=15777838840003")
class_Name = "." + "content-par"
x = driver.find_elements_by_css_selector(class_Name.replace(' ','.'))
web_content_list = []

for i in x:
    web_content_dict = {}
    web_content_dict["Title"] = i.text
    web_content_list.append(web_content_dict)

df = pd.DataFrame(web_content_list)
df.to_csv(r'C:\Users\intel\Desktop\data_file.csv',
         index=False, mode='a', encoding='utf-8')
