脚本宝典收集整理的这篇文章主要介绍了python爬虫- requests、httpx、aiohttp、scrapy突破ja3指纹识别，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。

异步模式：
import httpx
import asyncio
import random
import ssl
ORIGIN_CIPHERS = ('ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+HIGH:'

ciphers = ciphers + ":!aNULL:!eNULL:!MD5"
context = ssl.create_default_context()
context.set_ciphers(ciphers)
return context

async def main():
async with httpx.AsyncClient(verify=sslgen()) as client:
resp = await client.get('https://ja3er.com/json')
result = resp.json()
print(result)
asyncio.run(main())
同步模式：
import httpx
import asyncio
import random
