RSS feed with Basic HTTP Authentication using roUrlTransfer?

I'm trying to access an RSS feed that requires Basic HTTP Authentication, but I can't seem to get it to work. I've also created an equivalent example in Python that works correctly, and returns my expected results.

My BrightScript code:


'BrightScript example to retrieve a protected RSS feed with Basic HTTP Authentication.
'This does NOT work for me. http.GetToString() doesn't return anything.

http = CreateObject("roUrlTransfer")
http.SetUrl("http://www.my-restricted-site.com/")

ba = CreateObject("roByteArray")
ba.FromAsciiString("usernameSmiley Tongueassword")
http.AddHeader("Authorization", "Basic " + ba.ToBase64String())

print "Results: "; http.GetToString()

This equivalent example in Python works as expected:


#Python example to retrieve a protected RSS feed with Basic HTTP Authentication.
#This DOES work for me.

import urllib2
import base64

myurl = 'http://www.my-restricted-site.com/'
username = 'username'
password = 'password'

req = urllib2.Request(myurl)

base64string = base64.encodestring( '%s:%s' % (username, password) )[:-1]
authheader = "Basic %s" % base64string
req.add_header("Authorization", authheader)

try:
handle = urllib2.urlopen(req)
print handle.read()
except IOError, e:
print "Wrong user/pass"


The Roku documentation for ifUrlTransfer contains the following passage, which has me a little worried:


"Boolean SetUserAndPassword(String user, String password)
- Enables HTTP authentication using the specified user name and password. Note that HTTP basic authentication is deliberately disabled due to it being inherently insecure. HTTP digest authentication is supported.

Any help would be greatly appreciated.

Re: RSS feed with Basic HTTP Authentication using roUrlTrans

Not that it helps, but I use basic auth in MainSqueeze virtually identically to the SDK example you posted above, and it works great.

Re: RSS feed with Basic HTTP Authentication using roUrlTrans

Your code looks correct assuming your username is: "username" with a password of "password"

Alright, if I make an HTTP HEAD request, I get back a -77 response code.

Failure message:
error setting certificate verify locations:
CAfile: /etc/pki/tls/certs/ca-bundle.crt
CApath: none

Does that tell you anything?

From the docs:

-77 CURLE_SSL_CACERT_BADFILE could not load CACERT file, missing or wrong format

So, you need to be using https and call the SetCertificatesFile(), passing a PEM file that includes the CA cert that signed your web server's certificate. It's the SSL giving you problems, not the Basic Auth.

Yup, you were right! That fixed my problem.
