Can't request the "SEEN IT" section with #search + link.

[siers]

So, if you put a link into the reddit's search box, then it will show you where has that link already been submitted. It will redirect to /submit?url=your_url. Now, RedditKit doesn't do redirects.

With this code, it does:

module RedditKit
  class Client
    def middleware
      @middleware ||= Faraday::Builder.new do |builder|
        builder.use Faraday::Request::UrlEncoded
        builder.use RedditKit::Response::RaiseError
        builder.use RedditKit::Response::ParseJSON
        # *These two lines below allow the redirects to happen.*
        builder.use FaradayMiddleware::FollowRedirects
        builder.adapter :net_http
      end
    end
  end
end

And without the redirects, client.search('http://www.youtube.com/watch?v=XAAgXaMCdfI') just returned nil. Now, it returns nil only when it hasn't been submitted, a listing otherwise.

Thanks for identifying this problem but as always this is a problem with reddit's appalling api design. APIs should not redirect & clients most certainly should not follow them.

Problem

Well try searching this non-existent url:
http://reddit.com/search.json?q=http://www.youtube.com/watch?v=XAAgX54433aMCdfI2

You can see the response is:

"{}"

However, if you search this non-existent phrase:
http://reddit.com/search.json?q=fhhfhkjdfhkjfsfhjksdhjkdhjhj45784375437895hiudfhjkvkjkczjdasudouiryr35345783789rhsfhjkfsafioui73478923yudhgsSDFSJFHSJFHJKFJKHSSFKHJKJHSFKJHF24874872378dfkjdhajIUOQWUQWQE

The response is:

{"kind": "Listing", "data": {"modhash": "1rrvj60ghsw34387e669712d48255154140bd129cefbb3cf80", "children": [], "after": null, "before": null}}

This is stupid. This brakes RedditKit. This is reddit's api.

Solution
If you look at the source code:
https://github.com/reddit/reddit/blob/master/r2/r2/controllers/front.py#L871

You can see reddit detects whether something is a url then redirects the query to /submit?url={YOUR_URL}.

What we need to effectively do is detect whether something is a url then query:
reddit.com/submit.json?url={YOUR_URL}

This will return:
