net/http - Confirming the right implementation

Andrew Cowan

4/16/2008 1:22:00 AM

Hey folks, I am trying to use net/http and net/https to implement a
specific POST call for youtube's video upload service (am trying to use
the direct upload API) and am looking to confirm that I am implementing
the net/http library properly to do this. The full POST call is as
follows (this comes from the youtube API):

POST /feeds/api/users/default/uploads HTTP/1.1
Host: uploads.gdata.youtube.com
Authorization: ClientLogin auth=my_auth_token_here
X-GData-Key: key=my_dev_id_here
Slug: videofilename.mpg
Content-Type: multipart/related; boundary="f93dcbA3"
Content-Length: 1941255
Connection: close

--f93dcbA3
Content-Type: application/atom+xml; charset=UTF-8

<?xml version="1.0"?>
<entry <http://code.google.com/apis/youtube/reference.html#youtube_data_api_tag... xmlns="http://www.w3.org/2005/...

</media:group>
</entry>
--f93dcbA3
Content-Type: video/mp4
Content-Transfer-Encoding: binary

full_video_file_binary_contents_here
--f93dcbA3--




Here is the code I am using to implement this, am hoping to make sure
that I am using net/http correctly to pass all of the data where it
needs to be.

dev_id = 'my_YT_dev_id_here'
upload_host = 'uploads.gdata.youtube.com'
upload_path = '/feeds/api/users/my_username_here/uploads'


youtube_direct_upload( upload_host, upload_path, dev_id, video )


def youtube_direct_upload( host, path, dev_id, token, video )
data = <<"DATA"
--f93dcbA3
Content-Type: application/atom+xml; charset=UTF-8

<?xml version="1.0"?>
<entry xmlns="http://www.w3.org/2005/...

</media:group>
</entry>
--f93dcbA3
Content-Type: video/mpg
Content-Transfer-Encoding: binary

#{video}
--f93dcbA3--
DATA


http = Net::HTTP.new( host, 443 )
http.use_ssl = true

headers = {
'Host' => "#{host}",
'Authorization' => "GoogleLogin auth=#{token}",
'X-GData-Key' => "key=#{dev_id}",
'Slug' => 'videofile.mpg',
'Content-Type' => 'multipart/related; boundary="f93dcbA3"',
'Content-Length' => data.length.to_s,
'Connection' => 'close'
}

resp, data = http.post( path, data, headers )

puts 'Code: ' + resp.code
puts 'Data: '
puts data

end



I left out the code which rerieves the auth_token from the youtube
server as I have tested that aspect and it works fine, only having
trouble getting the above to work, when I try it I get this string of
errors:

/usr/local/lib/ruby/1.8/openssl/buffering.rb:178:in `syswrite': Broken
pipe (Errno::EPIPE)
from /usr/local/lib/ruby/1.8/openssl/buffering.rb:178:in `do_write'

from /usr/local/lib/ruby/1.8/net/http.rb:840:in `post'
from youtube_auth.rb:95:in `youtube_direct_upload'


I am hoping that I have simply implemented the net/http library
incorrectly, but am not sure... Any help would be greatly appreciated.

Thanks,
Andy

Hmm... Have you tried taking your post out of the
youtube_direct_upload method to see if you get the same error? Maybe
try these one by one to see if you can narrow it down:

Get rid of the headers
Get rid of the post body

Also, I assume that you have require 'net/http' and require 'net/
https' somewhere in there. You'd probably be getting a different
error if not.

The comments that I have around line 840 in http.rb say that the post
data must be a string. Maybe your video content is causing problems
(which would be a problem!).

I wanted to post a followup to this, I finally realized that I was
trying to use an ssl connection to the uploads. server for the direct
upload api when that was only needed for obtaining the ClientLogin auth
key. Replacing that with a normal http:// call solved the issue.
