Connecting to my own golang sever from outside world
问题
我确实有这段用go编写的代码：
// firstserver - 我的第一个服务器
package main
import (
"fmt"
"log"
"net/http"
)
func main() {
http.HandleFunc("/", Handler)
err := http.ListenAndServe(":80", nil)
if err != nil {
log.Fatal(err)
}
}
// Handler - 一个处理普通请求的处理函数
func Handler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintln(w, "你已连接")
}
现在，当我在浏览器中输入localhost:80（或者只输入localhost）时，页面加载完成，我看到了消息你已连接。现在我想尝试从其他设备连接。所以我拿起了我的另一台笔记本电脑。我检查了我的适配器地址，它是192.168.0.15。所以当我在另一台笔记本电脑上输入192.168.0.15:80时，它又一次工作了，很酷！
我主要是想做一个简单的服务器，以便在上大学时可以在手机上使用它，查看课程表，记录一些笔记等等。我拿起了我的智能手机，断开了WiFi连接，切换到了手机的移动网络，然后愚蠢地再次输入了192.168.0.15:80。我知道它不会工作，因为它不是我的外部IP地址。果然没有工作。
所以我查了一下我的ISP提供的IP地址，它看起来像这样：88.156.xxx.xx。现在我在手机上输入88.156.xxx.xx:80，但它不起作用。我尝试在SO和其他网络资源上搜索如何从局域网外部远程连接到我的服务器，但没有找到答案。有没有办法在不支付费用或类似的事情的情况下实现这一点？
附注：我住在一个租来的房间里，房子里不只有我一个人，所以我没有办法配置路由器（无论是手动还是通过网络配置）。
英文:
So I do have this code written in go:
// firstserver - my 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 - a handler function for a normal enter
func Handler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintln(w, "You're connected")
}
Now, when I go to my browser and type localhost:80 (or just localhost), the page loads, and I see the message You're connected. Now I wanted to try to connect from other devices too. So I took my other laptop. I checked my adapter address, its 192.168.0.15. So when I typed 192.168.0.15:80 on the other laptop, it worked again, cool!
Primarly I am trying to do some simple server to use it on my phone when I am at college, check the schedules, have some notes, etc. I took my smartphone, I disconnected from my WiFi, switched to my smartphones internet and dumbly typed 192.168.0.15:80 again. I knew it wouldn't work, cuz it's not my external IP. And it didn't.
So I looked up the IP address that my ISP provider gives me, it looks like this: 88.156.xxx.xx. Now on my phone I typed 88.156.xxx.xx:80 and it didn't work. I tried to search SO and other resources on the web on how to connect remotely to my server from outside of LAN. And I didn't find an answer. Is there a way to do that without, I don't know, paying for sorts of things, or something like this?
P.S I'm living in a rented room, there's not only me in the house, so I don't have a way to configure a router (manually or over the web)

你可以通过在具有公共IP的AWS免费层实例上部署它来实现。一旦你完成EC2实例的启动，将你的Web服务器的二进制文件复制到该实例上，使用以下命令：scp -i mykey.pem somefile.txt root@my.ec2.id.amazonaws.com:/。
你需要确保该实例的安全组允许来自互联网（0.0.0.0/0）在该端口上的入站流量。
要访问它：
使用EC2实例的公共IP或公共DNS，以及你的服务器的端口号（在你的情况下是80）。
英文:
One way you can do it is deploy it on an AWS Free Tier instance with public IP(https://aws.amazon.com/free/).
Once you are done spinning up the EC2 instance (https://aws.amazon.com/free/), copy the binary of your web server to that instance scp -i mykey.pem somefile.txt root@my.ec2.id.amazonaws.com:/
You need to ensure that the security group on that instance allows ingress from the internet(0.0.0.0/0) on that port
To access it:
Use either the public IP or public DNS of the EC2 instance along with the port number of your server(in your case 80)
