Python urllib3.util.ssl_ 模块，OP_NO_SSLv3() 实例源码

我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用urllib3.util.ssl_.OP_NO_SSLv3()。

def create_urllib3_context(ssl_version=None, cert_reqs=None,
                           options=None, ciphers=None):
    """All arguments have the same meaning as ``ssl_wrap_socket``.

    By default,this function does a lot of the same work that
    ``ssl.create_default_context`` does on Python 3.4+. It:

    - Disables SSLv2,SSLv3,and compression
    - Sets a restricted set of server ciphers

    If you wish to enable SSLv3,you can do::

        from urllib3.util import ssl_
        context = ssl_.create_urllib3_context()
        context.options &= ~ssl_.OP_NO_SSLv3

    You can do the same to enable compression (substituting ``COMPRESSION``
    for ``SSLv3`` in the last line above).

    :param ssl_version:
        The desired protocol version to use. This will default to
        PROTOCOL_SSLv23 which will negotiate the highest protocol that both
        the server and your installation of OpenSSL support.
    :param cert_reqs:
        Whether to require the certificate verification. This defaults to
        ``ssl.CERT_REQUIRED``.
    :param options:
        Specific OpenSSL options. These default to ``ssl.OP_NO_SSLv2``,
        ``ssl.OP_NO_SSLv3``,``ssl.OP_NO_COMPRESSION``.
    :param ciphers:
        Which cipher suites to allow the server to select.
    :returns:
        Constructed SSLContext object with specified options
    :rtype: SSLContext
    """
    context = SSLContext(ssl_version or ssl.PROTOCOL_SSLv23)

    # Setting the default here,as we may have no ssl module on import
    cert_reqs = ssl.CERT_REQUIRED if cert_reqs is None else cert_reqs

    if options is None:
        options = 0
        # SSLv2 is easily broken and is considered harmful and dangerous
        options |= OP_NO_SSLv2
        # SSLv3 has several problems and is now dangerous
        options |= OP_NO_SSLv3
        # Disable compression to prevent CRIME attacks for OpenSSL 1.0+
        # (issue #309)
        options |= OP_NO_COMPRESSION

    context.options |= options

    if getattr(context, 'supports_set_ciphers', True):  # Platform-specific: Python 2.6
        context.set_ciphers(ciphers or DEFAULT_CIPHERS)

    context.verify_mode = cert_reqs
    if getattr(context, 'check_hostname', None) is not None:  # Platform-specific: Python 3.2
        # We do our own verification,including fingerprints and alternative
        # hostnames. So disable it here
        context.check_hostname = False
    return context
