How to upload video on YouTube with Ruby

问题

I am trying to upload a youtube video using the GData gem (I have seen the youtube_g gem but would like to make it work with pure GData if possible), but I keep getting this error:

GData::Client::BadRequestError in 'MyProject::Google::YouTube should upload the actual video to youtube (once it does, mock this test out)' request error 400: No file found in upload request.

I am using this code:

def metadata
  data = <<-EOF
<?xml version="1.0"?>
<entry xmlns="http://www.w3.org/2005/Atom"
  xmlns:media="http://search.yahoo.com/mrss/"
  xmlns:yt="http://gdata.youtube.com/schemas/2007">
  <media:group>
    <media:title type="plain">Bad Wedding Toast</media:title>
    <media:description type="plain">
      I gave a bad toast at my friend's wedding.
    </media:description>
    <media:category scheme="http://gdata.youtube.com/schemas/2007/categories.cat">People</media:category>
    <media:keywords>toast, wedding</media:keywords>
  </media:group>
</entry>
EOF
end

@yt = GData::Client::YouTube.new
@yt.clientlogin("name", "pass")
@yt.developer_key = "myKey"
url = "http://uploads.gdata.youtube.com/feeds/api/users/name/uploads"
mime_type = "multipart/related"
file_path = "sample_upload.mp4"
@yt.post_file(url, file_path, mime_type, metadata)

What is the recommended/standard way for uploading videos to youtube with ruby, what is your method?

Update

After applying the changes to wrapped_entry, the string it produces looks like this:

--END_OF_PART_59003
Content-Type: application/atom+xml; charset=UTF-8
<?xml version="1.0"?>
<entry xmlns="http://www.w3.org/2005/Atom"
  xmlns:media="http://search.yahoo.com/mrss/"
  xmlns:yt="http://gdata.youtube.com/schemas/2007">
  <media:group>
    <media:title type="plain">Bad Wedding Toast</media:title>
    <media:description type="plain">
      I gave a bad toast at my friend's wedding.
    </media:description>
    <media:category scheme="http://gdata.youtube.com/schemas/2007/categories.cat">People</media:category>
    <media:keywords>toast, wedding</media:keywords>
  </media:group>
</entry>

--END_OF_PART_59003
Content-Type: multipart/related
Content-Transfer-Encoding: binary

... and inspecting the request and response looks like this:

Request:

Still not working, I'll have to check it out more with those changes.

回答1:

Not sure if you ever fixed this, but I believe the mime_type param in post_file should be set to the mime_type of the video - you've got it set to "multipart/related" in your sample code.

回答2:

I apologize for just linking but I think this may help out linky

回答3:

I had the same problem with gdata gem.

This fixed it for me.

C:\Ruby\lib\ruby\gems\1.8\gems\gdata-1.1.1\lib\gdata\http

In "class MimeBody" replace "wrap_entry" with this code to fix it.

"def wrap_entry(entry, file_mime_type) wrapped_entry = "--#{@boundary}\r\n" wrapped_entry += "Content-Type: application/atom+xml; charset=UTF-8\r\n\r\n" wrapped_entry += entry wrapped_entry += "\r\n--#{@boundary}\r\n" wrapped_entry += "Content-Type: #{file_mime_type}\r\n" wrapped_entry += "Content-Transfer-Encoding: binary\r\n\r\n"
return MimeBodyString.new(wrapped_entry) end"
