使用Content API插入Google Merchant数据供稿

Question

I'm trying to insert some data into my merchant account data feed using the Content API. Using the code below, I've been given a "POST requests require a Content-length header. That's all we know." error, but I've set the content length, so I'm really confused.

One theory I have is that it doesn't know where to put these requests, under my merchant account ID, I have two data feeds, and I'm not sure how to set it to enter into a given data feed.

The XML is stolen from here: https://developers.google.com/shopping-content/batch-operations

@feed = '<?xml version="1.0"?>
    <feed xmlns="http://www.w3.org/2005/Atom"
        xmlns:openSearch="http://a9.com/-/spec/opensearchrss/1.0/"

    http = HTTPClient.new
    @output = http.post('https://content.googleapis.com/content/v1/<myMerchantID>/items/products/schema/batch', {},"content"=> @feed, "Content-length"=>@feed.length.to_s, "GData-Version"=> "1", "Authorization" => "AuthSub token=myToken", "Content-Type"=> "application/atom+xml")
