How to properly format json to send over using RestClient - ruby-on-rails

Question

I am trying to implement this javascript code
var token = "<page_access_token>";
function sendTextMessage(sender, text) {
messageData = {
text:text
}
request({
url: 'https://graph.facebook.com/v2.6/me/messages',
qs: {access_token:token},
method: 'POST',
json: {
recipient: {id:sender},
message: messageData,
}
}, function(error, response, body) {
if (error) {
console.log('Error sending message: ', error);
} else if (response.body.error) {
console.log('Error: ', response.body.error);
}
});
}
into ruby on rails code
def reply_back(sender, text)
page_token = "*****"
base_uri = "https://graph.facebook.com/v2.6/me/messages"
messageData = {
text: text
}
qs = {
access_token: page_token
}
json = {
recipient: {
id: sender
},
message: messageData
}
response = RestClient.post base_uri, qs.to_json, json.to_json, :content_type => :json, :accept => :json
p "this is the response #{response}"
end
but obviously i am doing something wrong, i am getting this in console
(wrong number of arguments (4 for 2..3))
on line
response = RestClient.post base_uri, qs.to_json, json.to_json, :content_type => :json, :accept => :json
any insight?

Answer 1

You should put all your params in one params hash like this:
params = {
recipient: { id: sender },
message: { text: text },
access_token: page_token
}
response = RestClient.post base_uri, params.to_json, content_type: 'application/json', accept: 'application/json'
p "this is the response #{response}"

Answer 2

According to documentation, you should merge you params and pass it in method as one object:
params = qs.merge(json)
response = RestClient.post(base_uri,
params.to_json,
content_type: :json, accept: :json)
This method expects 2 or 3 arguments. In this case the third argument is a hash { content_type: :json, accept: :json }. Since it is a last argument, you can omit curly braces.
