python 3.73 (Windows, urllib3) ssl.SSLCertVerificationError : [SSL: CERTIFICATE_VERIFY_FAILED]

Question

执行简单代码后:

from urllib3 import ProxyManager

def GET(url):
    http = ProxyManager("https://91.208.39.70:8080")
    response = http.urlopen('GET', url)
    print(response.data)
    return ''


if __name__ == '__main__':
    result = GET("https://example.com")
    print(result)

我有下一个错误:

Traceback (most recent call last): File "F:\Run\Lprogr\Phyton\lib\site-packages\urllib3\connectionpool.py", line 597, in urlopen self._prepare_proxy(conn) File "F:\Run\Lprogr\Phyton\lib\site-packages\urllib3\connectionpool.py", line 807, in _prepare_proxy conn.connect() File "F:\Run\Lprogr\Phyton\lib\site-packages\urllib3\connection.py", line 350, in connect ssl_context=context) File "F:\Run\Lprogr\Phyton\lib\site-packages\urllib3\util\ssl_.py", line 355, in ssl_wrap_socket return context.wrap_socket(sock, server_hostname=server_hostname) File "F:\Run\Lprogr\Phyton\lib\ssl.py", line 412, in wrap_socket session=session File "F:\Run\Lprogr\Phyton\lib\ssl.py", line 853, in _create self.do_handshake() File "F:\Run\Lprogr\Phyton\lib\ssl.py", line 1117, in do_handshake self._sslobj.do_handshake() ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1056)

During handling of the above exception, another exception occurred:

更新:我不想忽略证书验证。

Answer 1

证书是为域名而不是 ip 注册的。您可以在域名上发出请求，或者您忽略 ssl 验证(参见 here )，或者将 https 替换为http(仅当服务器允许 http 连接时才有效)
