Ruby Rest client POST, how to send headers - ruby-on-rails

Question

Ruby rest client is not able to send headers, my java service is not able to read headers when I trigger post request from ruby as below. My Service layers throws error Header companyID is missing. When run the same http request in Postman it works.
response = RestClient::Request.new({
method: :post,
url: 'https://example.com/submitForm',
headers:{content_type: 'application/x-www-form-urlencoded',
companyID:'Company1',
Authorization:'Basic HELLO1234'},
payload: { data: str_res}
}).execute do |response, request, result|
case response.code
when 400
[ :error, JSON.parse(response.to_str) ]
when 200
[ :success, JSON.parse(response.to_str) ]
puts request.headers
else
fail "Invalid response #{response.to_str} received."
end
end
Here is postman code that works. Need similar in Ruby Rest, pls advise.
POST /submitForm HTTP/1.1
Host: example.com
companyID: Company1
Authorization: Basic HELLO1234
Content-Type: application/x-www-form-urlencoded
Cache-Control: no-cache
Postman-Token: 528cafa1-2b5d-13a1-f227-bfe0171a9437
data=My Own data

Answer 1

Below worked. Looks like headers should be in same line.
payloadString = "data=My Own data"
response = RestClient::Request.new({
method: :post,
url: 'https://example.com/submitForm',
payload: payloadString,
headers: {content_type: 'application/x-www-form-urlencoded', companyID:'Company1', Authorization:'Basic HELLO1234'}
}).execute do |response, request, result|
case response.code
when 400
[ :error, JSON.parse(response.to_str) ]
when 200
[ :success, JSON.parse(response.to_str) ]
else
fail "Invalid response #{response.to_str} received."
end
end

Try using the RestClient post method:
result = RestClient.post(
'https://example.com/submitForm',
payload,
{
content_type: 'application/x-www-form-urlencoded',
companyID: 'Company1',
Authorization: 'Basic HELLO1234'
}
)
Payload in this instance is a string, so you'll need to figure out the appropriate structure for application/x-www-form-urlencoded. For example:
payload.to_json => '{"data": "str_res"}'
