Using RestClient instead of curl -- how do I do that? - ruby

Question

I am trying to use RestClient to do the following which is currently in Curl:
curl -H "Content-Type: application/json" -X POST --data '{"contacts" : [1111],"text" : "Testing"}' https://api.sendhub.com/v1/messages/?username=NUMBER\&api_key=APIKEY
I don't see in the docs for RestClient how to perform the equivalent as "--data" above as well as passing -H (Header) information.
I tried the following:
url = "https://api.sendhub.com/v1/messages/?username=#{NUMBER}\&api_key=#{APIKEY}"
smspacket = "{'contacts':[#{contact_id}], 'text' : ' #{text} ' }"
RestClient.post url , smspacket, :content_type => 'application/json'
But this give me a Bad Request error.

I presume this is probably very late, but for the record and since I was hanging around with my own question.
Your problem weren't really with the use or not of the :to_json method, since it will output a string anyway. The body request has to be a string.
According to http://json.org strings in json have to be defined with " and not with ', even if in javascript we mostly used to write json this way. Same if you use no quote at all for keys.
This is probably why you received a bad request.
pry(main)> {"test": "test"}.to_json
"{\"test\":\"test\"}"
pry(main)> JSON.parse(RestClient.post('http://httpbin.org/post', "{'test': 'test'}", {content_type: :json, accept: :json}).body)["json"]
nil
pry(main)> JSON.parse(RestClient.post('http://httpbin.org/post', '{test: "test"}', {content_type: :json, accept: :json}).body)["json"]
nil
pry(main)> JSON.parse(RestClient.post('http://httpbin.org/post', '{"test": "test"}', {content_type: :json, accept: :json}).body)["json"]
{"test"=>"test"}
