Advanced Usage

low-level curl API

Alternatively, you can use the low-level curl-like API:

from curl_cffi import Curl, CurlOpt
from io import BytesIO

buffer = BytesIO()
c = Curl()
c.setopt(CurlOpt.URL, b'https://tls.browserleaks.com/json')
c.setopt(CurlOpt.WRITEDATA, buffer)

c.impersonate("chrome120")

c.perform()
c.close()
body = buffer.getvalue()
print(body.decode())

s.get(url)
