SSL version in httplib2 - EOF occurred in violation of protocol

Question

I\'m issuing a HTTPS GET request to a REST service I own with httplib2 but we\'re getting the error:

[Errno 8] _ssl.c:504: EOF occurred in violation of prot         


        

Answer 1

I developed this workaround for httplib2 :

import httplib2

# Start of the workaround for SSL3
# This is a monkey patch / module function overriding 
# to allow pages that only work with SSL3

# Build the appropriate socket wrapper for ssl
try:
    import ssl # python 2.6
    httplib2.ssl_SSLError = ssl.SSLError
    def _ssl_wrap_socket(sock, key_file, cert_file,
                         disable_validation, ca_certs):
        if disable_validation:
            cert_reqs = ssl.CERT_NONE
        else:
            cert_reqs = ssl.CERT_REQUIRED
        # Our fix for sites the only accepts SSL3
        try:
            # Trying SSLv3 first
            tempsock = ssl.wrap_socket(sock, keyfile=key_file, certfile=cert_file,
                                       cert_reqs=cert_reqs, ca_certs=ca_certs,
                                       ssl_version=ssl.PROTOCOL_SSLv3)
        except ssl.SSLError, e:
            tempsock = ssl.wrap_socket(sock, keyfile=key_file, certfile=cert_file,
                                       cert_reqs=cert_reqs, ca_certs=ca_certs,
                                       ssl_version=ssl.PROTOCOL_SSLv23)
        return tempsock
    httplib2._ssl_wrap_socket = _ssl_wrap_socket
except (AttributeError, ImportError):
    httplib2.ssl_SSLError = None
    def _ssl_wrap_socket(sock, key_file, cert_file,
                         disable_validation, ca_certs):
        if not disable_validation:
            raise httplib2.CertificateValidationUnsupported(
                    "SSL certificate validation is not supported without "
                    "the ssl module installed. To avoid this error, install "
                    "the ssl module, or explicity disable validation.")
        ssl_sock = socket.ssl(sock, key_file, cert_file)
        return httplib.FakeSocket(sock, ssl_sock)
    httplib2._ssl_wrap_socket = _ssl_wrap_socket

# End of the workaround for SSL3

if __name__ == "__main__":
    h1 = httplib2.Http()
    resp, content = h1.request("YOUR_SSL3_ONLY_LINK_HERE", "GET")
    print(content)

This workaround was based on the workarounds for urllib2 presented at this bug report http://bugs.python.org/issue11220,

Update: Presenting a solution for httplib2. I didn't notice you were using httplib2, I thought it was urllib2.

Answer 2

Please refer to another StackOverflow threads that specify a solution. The way to specify a TLS version force the SSL version to TLSv1 as mentioned in the response by user favoretti within the provided link.

Hopefully, this works
