I am trying to verify the that target exposes a https web service. I have code to connect via HTTP but I am not sure how to connect via HTTPS. I have read you use SSL but I have also read that it did not support certificate errors. The code I have got is from the python docs:
import httplib conn = httplib.HTTPConnection("www.python.org") conn.request("GET", "/index.html") r1 = conn.getresponse() print r1.status, r1.reason
Does anyone know how to connect to HTTPS?
I already tried the HTTPSConenction but it responds with an error code claiming httplib does not have attribute HTTPSConnection. I also don't have socket.ssl available.
I have installed Python 2.6.4 and I don't think it has SSL support compiled into it. Is there a way to integrate this suppot into the newer python without having to install it again.
I have installed OpenSSL and pyOpenSsl and I have tried the below code from one of the answers:
import urllib2 from OpenSSL import SSL try: response = urllib2.urlopen('https://example.com') print 'response headers: "%s"' % response.info() except IOError, e: if hasattr(e, 'code'): # HTTPError print 'http error code: ', e.code elif hasattr(e, 'reason'): # URLError print "can't connect, reason: ", e.reason else: raise
I have got an error:
Traceback (most recent call last): File "<stdin>", line 2, in <module> File "/home/build/workspace/downloads/Python-2.6.4/Lib/urllib.py", line 87, in urlopen return opener.open(url) File "/home/build/workspace/downloads/Python-2.6.4/Lib/urllib.py", line 203, in open return self.open_unknown(fullurl, data) File "/home/build/workspace/downloads/Python-2.6.4/Lib/urllib.py", line 215, in open_unknown raise IOError, ('url error', 'unknown url type', type) IOError: [Errno url error] unknown url type: 'https'
Does anyone know how to get this working?
I have found out what the problem was, the Python version I was using did not have support for SSL. I have found this solution currently at: http://www.webtop.com.au/compiling-python-with-ssl-support.
The code will now work after this solution which is very good. When I import ssl and HTTPSConnection I know don't get an error.
Thanks for the help all.
Python 2.x: docs.python.org/2/library/httplib.html:
Note: HTTPS support is only available if the socket module was compiled with SSL support.
Python 3.x: docs.python.org/3/library/http.client.html:
Note HTTPS support is only available if Python was compiled with SSL support (through the ssl module).
#!/usr/bin/env python import httplib c = httplib.HTTPSConnection("ccc.de") c.request("GET", "/") response = c.getresponse() print response.status, response.reason data = response.read() print data # => # 200 OK # <!DOCTYPE html ....
To verify if SSL is enabled, try:
>>> import socket >>> socket.ssl <function ssl at 0x4038b0>
To check for ssl support in Python 2.6+:
try: import ssl except ImportError: print "error: no ssl support"
To connect via https:
import urllib2 try: response = urllib2.urlopen('https://example.com') print 'response headers: "%s"' % response.info() except IOError, e: if hasattr(e, 'code'): # HTTPError print 'http error code: ', e.code elif hasattr(e, 'reason'): # URLError print "can't connect, reason: ", e.reason else: raise
