關於爬蟲初期學習爬取小說的問題

剛學完爬蟲基礎,由於這是沒有學習框架時候的**,可能會顯得有些囉嗦,不過裡邊有很多自己的想法,可以參考並提出意見.

由於當時寫的比較匆忙,沒有用到物件導向的思想去編寫**,所以這裡只是用到了函式

import json

import os

import re

import urllib.request

import time

from pprint import pprint

from selenium import webdriver

from selenium.webdriver.chrome.options import options

#這裡由於爬取的****內容是js載入的,所以我採用selenium模擬瀏覽器的方法

chrome_options = options()

chrome_options.add_argument(』–headless』)

chrome_options.add_argument(』–disable-gpu』)

path = r'e:\pycharm\課件\chromedriver_win32\chromedriver.exe'

driver = webdriver.chrome(executable_path=path,chrome_options=chrome_options)
url = url
driver.get(url)
time.sleep(7)
# pprint(driver.page_source)
return driver.page_source

time.sleep(1)
