python3使用pyppeteer繞過navigator.webdriver的腳本特徵值檢測

如今,網上說的檢測腳本特徵值的辦法是

# chrome啓動
# F12 console 輸入
navigator.webdriver
# 腳本被識別則返回
>> true 
# 正常瀏覽器會返回
>> undefined
# 或者
>>False

以上是目前網上比較流行的腳本檢測一種說法,如果有其他

pyppeteer 是什麼?

pyppeteer是基於node.js操作chromium的非官方模塊
是網上文章比較流程的一種,用來替代selenium繞過驅動器特徵值檢測的一個模塊,網上文章常見例子,淘寶滑動條

pyppeteer與selenium[python其他常見模塊]的代碼風格有比較大的差異,上手需要點耐心
迴歸正題:

然而並非可以直接繞過 navigator.webdriver 的檢測
還需要一定的設置[在方法main()中]
以下代碼實例:

# -*-coding:utf-8 -*-
import asyncio
from pyppeteer import launch
import random
from lxml import etree

# 返回一個隨機的請求頭 headers
