http - Connecting to my own golang sever from outside world -


so have code written in go:

// firstserver - first server package main  import (     "fmt"     "log"     "net/http" )  func main() {     http.handlefunc("/", handler)     err := http.listenandserve(":80", nil)     if err != nil {         log.fatal(err)     } }  // handler - handler function normal enter func handler(w http.responsewriter, r *http.request) {     fmt.fprintln(w, "you're connected") }

now, when go browser , type localhost:80 (or localhost), page loads, , see message you're connected. wanted try connect other devices too. took other laptop. checked adapter address, 192.168.0.15. when typed 192.168.0.15:80 on other laptop, worked again, cool!

primarly trying simple server use on phone when @ college, check schedules, have notes, etc. took smartphone, disconnected wifi, switched smartphones internet , dumbly typed 192.168.0.15:80 again. knew wouldn't work, cuz it's not external ip. , didn't.

so looked ip address isp provider gives me, looks this: 88.156.xxx.xx. on phone typed 88.156.xxx.xx:80 , didn't work. tried search , other resources on web on how connect remotely server outside of lan. , didn't find answer. there way without, don't know, paying sorts of things, or this?

p.s i'm living in rented room, there's not me in house, don't have way configure router (manually or on web)

one way can deploy on aws free tier instance public ip(https://aws.amazon.com/free/). once done spinning ec2 instance (https://aws.amazon.com/free/), copy binary of web server instance scp -i mykey.pem somefile.txt root@my.ec2.id.amazonaws.com:/ need ensure security group on instance allows ingress internet(0.0.0.0/0) on port

to access it: use either public ip or public dns of ec2 instance along port number of server(in case 80)

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
