Hello everyone,
I'm new to ruby.I'm trying to write an application that would
synchronise with google calendar.Below is a script I'm trying to use for
authentication with google.When I try to run it I'm getting a bad file
descriptor error.I have also provided the error message just after the
script.Any help will be appriciated.Thank you in advance.

def authentication(email,passwd,service)
require 'net/https'
http = Net::HTTP.new('www.google.com', 443)
http.use_ssl = true
path = '/accounts/ClientLogin'


# Now we are passing in our actual authentication data.
data = 'accountType=HOSTED_OR_GOOGLE&Email=email &Passwd=passwd
&service=service'

# Set up a hash for the headers
headers = { 'Content-Type' => 'application/x-www-form-urlencoded'}

# Post the request and print out the response to retrieve our
authentication token
resp, data = http.post(path, data, headers)

# Strip out our actual token (Auth) and store it
cl_string = data[/Auth=(.*)/, 1]

# Build our headers hash and add the authorization token
headers["Authorization"] = "GoogleLogin auth=#{cl_string}"
end



#After calling this function like this:
authentication("(e-mail address removed)","passwd","cl")

#I get the follow error message:

very carefully check the parameters to make sure they're right is the
only thing I can imagine.

I believe you would see a different error. EBADF occurs, if the file
descriptor (i.e. the numeric value) is invalid. You can provoke it by
doing something like this

ruby -e 'File.open(10, "w") {|f| f.puts "test"}'

Whereas it does not happen if you do

ruby -e 'File.open(1, "w") {|f| f.puts "test"}'

One way to create this is to open a file, remember the number returned
from #fileno, close the file and then open another file with the
remembered number (file descriptor).

Kind regards

robert
