support to send response to client ?

resp = EM::HttpRequest.new('https://jsonplaceholder.typicode.com/posts/1')
http = resp.get
http.callback do |r|
#send_data or response to client">>>response is: #{r.response}" not receiving response on postman
end
I'm calling this code from postman but not getting any response there
That's not the correct request/response flow. If you want to send data to the endpoint, you must pass the data either as a request body, or as part of the query string. Both of those must be provided before the callback.. the callback is what's fires once you get the response back from the server.
E.g. https://github.com/igrigorik/em-http-request/wiki/Issuing-Requests#posting-data
the callback is what's fires once you get the response back from the server.
I want to send response which I get from server to the client
You already have the response.
http.callback {
p http.response_header.status
p http.response_header
p http.response
}
yes it is only printing the response but I'm not getting anything in the postman also the request/response cycle does not ends
Below code is sending response to postman resp.send_response
is sending response to client
class Handler < EventMachine::Connection
include EventMachine::HttpServer
def process_http_request
resp = EventMachine::DelegatedHttpResponse.new( self )
sleep 2 # Simulate a long running request
resp.status = 200
resp.content = "Hello World!"
resp.send_response # this is sending response to postman
end
end
EventMachine::run {
EventMachine::start_server("0.0.0.0", 8080, Handler)
puts "Listening..."
}
