一、使用步骤

1.随机生成指纹

import random
import requests
from requests.adapters import HTTPAdapter
from requests.packages.urllib3.util.ssl_ import create_urllib3_context
ORIGIN_CIPHERS = (
    'ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+HIGH:DH+HIGH:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+HIGH:RSA+3DES')

class DESAdapter(HTTPAdapter):
    def __init__(self, *args, **kwargs):
        CIPHERS = ORIGIN_CIPHERS.split(":")
        random.shuffle(CIPHERS)

        CIPHERS = ":".join(CIPHERS)
        self.COPHERS = CIPHERS + ":!aNULL:!eNULL:!MD5"
        super(DESAdapter, self).__init__(*args, **kwargs)

    def init_poolmanager(self, *args, **kwargs):
        context = create_urllib3_context(ciphers=self.COPHERS)
        kwargs["ssl_context"] = context
        return super(DESAdapter, self).init_poolmanager(*args, **kwargs)

    def proxy_manager_for(self, *args, **kwargs):
        context = create_urllib3_context(ciphers=self.COPHERS)
        kwargs["ssl_context"] = context


if __name__ == '__main__':
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:101.0) Gecko/20100101 Firefox/101.0'
    }
    s = requests.Session()
    s.headers.update(headers)
    for _ in range(5):
        s.mount("https://tls.browserleaks.com", DESAdapter())

        response = s.get('https://tls.browserleaks.com/json',verify=False)
        print(response.json())

random.shuffle(CIPHERS) 这里是每次都是随机调整 CIPHERS ，所以每次生成的指纹都是不一样的

2.curl_cffi 生成指纹

代码如下（示例）：

from curl_cffi import requests
for _ in range(5):
    r = requests.get("https://tls.browserleaks.com/json", impersonate="chrome101")
    print(r.json())

这里生成的指纹根据impersonate 参数生成后不会再次变动

2.httpx+ssl 生成指纹

# 默认 cipher 在这里定义：https://github.com/encode/httpx/blob/master/httpx/_config.py
import ssl
import httpx

# create an ssl context
ssl_context = ssl.SSLContext(protocol=ssl.PROTOCOL_TLS)
CIPHERS = 'DH+AES:RSA+AES'
ssl_context.set_ciphers(CIPHERS)

r = httpx.get('https://tls.browserleaks.com/json', verify=ssl_context)
print(r.text)
