Send API get request from AWS Lambda in ruby - ruby

Question

I was trying to send API request to my rails server from AWS Lambda function.
I was using httparty gem to send request.
I have tried with below code
require "httparty"
class PostManager
include HTTParty
def initialize
end
def create_post(job_id)
puts "----------------- Inside post manager ------------------"
puts "----------------- #{ENV["BASE_URI"]} ------------------"
puts "#{ENV['BASE_URI']}/call_response?job_id=#{job_id}"
response = HTTParty.get("#{ENV['BASE_URI']}")
puts "******************HTTP Response -: #{response}******************"
response
end
end
I am triggering this code from aws lambda main handler like below.
post_manager = PostManager.new
response = post_manager.create_post(job_id)
But lambda function gets timeout. Request not reaching to rails server at all.
Please guide me if i am missing something. Other alternatice to send post request to external server from aws lambda function is also invited.

Since http party is a http client, I recommend read the documentation, start experimenting with pry and a site like http://httpbin.org
So went will have all the thinks. reading your code I'm not sure of what you want to achieve, but I think that you want to connect to some en point that is on:
The domain inside this shell variable => #{ENV['BASE_URI']}
the path of the http method => call_response
and some path parameters like => job_id=#{job_id}
You allways say that this is a post but you are doing a get => HTTParty.get
So let's start with some object like the one showed in the documentation in order to attack to this method with curl will be something like this:
❯ curl -X GET "http://httpbin.org/get?job_id=4" -H "accept: application/json" ~/learn/ruby/stackoverflow
{
"args": {
"job_id": "4"
},
"headers": {
"Accept": "application/json",
"Host": "httpbin.org",
"User-Agent": "curl/7.64.1",
"X-Amzn-Trace-Id": "Root=1-613b73ef-2d00166a2ae40e704b448352"
},
"origin": "83.53.251.55",
"url": "http://httpbin.org/get?job_id=4"
}
Then for an http client object
add this to afile called httpbin_client.rb :
require 'httparty'
class HTTPbinClient
include HTTParty
base_uri ENV['BASE_URI']
def initialize
end
def ask_for_job_id(job_id)
self.class.get('/get', {query: {job_id: job_id}})
end
end
http_bin = HTTPbinClient.new
puts http_bin.ask_for_job_id(28)
call like this:
❯ BASE_URI=httpbin.org ruby httpbin_client.rb ~/learn/ruby/stackoverflow
{
"args": {
"job_id": "28"
},
"headers": {
"Accept": "*/*",
"Accept-Encoding": "gzip;q=1.0,deflate;q=0.6,identity;q=0.3",
"Host": "httpbin.org",
"User-Agent": "Ruby",
"X-Amzn-Trace-Id": "Root=1-613b776d-47036b9b29bb1ae34b4a0e50"
},
"origin": "83.53.251.55",
"url": "http://httpbin.org/get?job_id=28"
}
