Fusion Tables: Why do I keep getting a "400 Bad Request" error when trying to update a table style via Ruby's RestClient gem

Question

I'm trying to update a style for one of my Fusion Tables by using the Ruby gem RestClient.

Here's my code:

require 'rest_client'

tableId = '<STRING CONTAINING TABLEID>'
styleId = '<STRING CONTAINING STYLEID>'
key = '<STRING CONTAINING MY FUSION TABLES API KEY>'

table_url = "https://www.googleapis.com/fusiontables/v1/tables/#{tableId}/styles/#{styleId}?key=#{key}"
update = '{"polygonOptions": {"strokeColor":"#ffffff"}}'

token = 'STRING CONTAINING AUTHORIZATION TOKEN'

RestClient.put table_url,update,{"Authorization" => "Bearer #{token}"}

When I run that code, I get this error:

C:/Ruby193/lib/ruby/gems/1.9.1/gems/rest-client-1.6.7/lib/restclient/abstract_response.rb:48:in `return!': 400 Bad Request (RestClient::BadRequest)
    from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rest-client-1.6.7/lib/restclient/request.rb:230:in `process_result'

    from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rest-client-1.6.7/lib/restclient/request.rb:172:in `transmit'
    from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rest-client-1.6.7/lib/restclient/request.rb:64:in `execute'
    from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rest-client-1.6.7/lib/restclient/request.rb:33:in `execute'
    from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rest-client-1.6.7/lib/restclient.rb:80:in `put'

When I input the update code into Google's official Style request PUT maker thingie, the update works. But it does not work when I run my Ruby code.

Does anyone know what I am doing wrong?

EDIT: Extra output I get from adding in RestClient.log = logger

RestClient.put "https://www.googleapis.com/fusiontables/v1/tables/<MY TABLE ID HERE>/styles/4?key=<AND HERE'S WHERE MY FUSION TABLE API KEY GOES>", "{\"polygonOptions\":{\"strokeColor\":\"#ffffff\"}}", "Accept"=>"*/*; q=0.5, application/xml", "Accept-Encoding"=>"gzip, deflate", "Authorization"=>"Bearer <THIS CONTAINS THE BEARER STRING>", "Content-Length"=>"44"
# => 400 BadRequest | application/json 255 bytes

Answer 1

You really should be using the google-api-ruby-client library instead of building your own REST calls. The library abstracts a lot of the OAuth stuff and formatting of the parameters for you.

Having said that, can you enable debugging for your RestClient and post the output of the RestClient call along with the output from Google official PUT maker thingie (I like your technical jargon there)? Comparing the two should show how they differ and what Google doesn't like with yours.
