[BUG] Cannot change proxy on the fly

[sd5986]

Describe the bug

After you make a request to a website (i.e first request) with a proxy server, in the second request, try to use another proxy server, it would not work.

    raise RequestsError(str(e), e.code, rsp) from e
curl_cffi.requests.errors.RequestsError: Failed to perform, curl: (35) BoringSSL SSL_connect: SSL_ERROR_SYSCALL in connection to www.google.com:443 . See https://curl.se/libcurl/c/libcurl-errors.html first for more details.

I have tried using a.s.proxies = {'https': 'socks5h://127.0.0.1:2085/'} as well. After changing, it also gives the same error.

To Reproduce

from curl_cffi import requests

class new_ins():

    def __init__(self):
        self.s = requests.Session(impersonate='chrome124')
        self.original_get = self.s.get
        self.s.get = self.override_cffi_get
    def override_cffi_get(self,*args,**kwargs):
        print(args)
        print(kwargs)
        response = self.original_get(*args,**kwargs)
        return response


def req():

    #s = httpx.Client()
    a = new_ins()
    # a.s.proxies = {'https': 'socks5h://127.0.0.1:2080/',
    #                'http': 'socks5h://127.0.0.1:2080/'}
    proxy = 'socks5h://127.0.0.1:2080/'
    print(a.s.get(url='https://www.google.com/',proxy=proxy).content)
    #a.s.proxies = {'https': 'socks5h://127.0.0.1:2085/'}
    #a.s.curl.setopt(curl_cffi.CurlOpt.PROXY,'socks5h://127.0.0.1:2085')
    input()
    proxy = 'socks5://127.0.0.1:2085/'
    print(a.s.get(url='https://www.google.com/',proxy=proxy).content)
    input()

Expected behavior
A clear and concise description of what you expected to happen.

The program will be change it's proxy server in the next request

Versions

• OS: Mac OS 14.5, Ubuntu
• curl_cffi version [e.g. 0.5.7]
• pip freeze dump

Additional context

• Which session are you using? async or sync?
• If using async session, which loop implementation are you using?

- a.s.curl.setopt(curl_cffi.CurlOpt.PROXY,'socks5h://127.0.0.1:2085')
+ proxy = 'socks5://127.0.0.1:2085/'

It seems that you switched from socks5h to socks5 accidentally.

Nah I did it intentionally to see if socks5/socks5h caused the problem. I also tried socks5h as well. It won't work. Btw, this might be a libcurl bug

I only found curl/curl#648, which has been fixed, though.

I do not know why this bug happens too :( . But create a new session and copy headers, cookies to the new one with another proxy server specified, works flawlessly.

Try adding verify=False
self.s = requests.Session(impersonate='chrome124', verify=False)
