支持https访问

1. 打开自己的云服务器的 80 和 443 端口

打开某为云官网 https://console.huaweicloud.com/

2. 安装 nginx

sudo apt update
sudo apt-get install nginx
nginx -v

3. 安装 snapd

sudo apt install snapd
sudo apt-get remove certbot

4. 安装 certbot

sudo snap install --classic certbot

5. 生成证书

sudo certbot certonly --nginx

6. 拷贝生成的证书到项目工作目录

cd ~/dev/go/screen_share
mkdir conf
cp /etc/letsencrypt/live/www.liangzixuexi.com/fullchain.pem   ~/dev/go/screen_share/conf/
cp /etc/letsencrypt/live/www.liangzixuexi.com/privkey.pem   ~/dev/go/screen_share/conf/

7. 修改 main.go 程序如下

package mainimport ("fmt""net/http"
)func main() {// 1.定义一个 URL 前缀staticURL := "/static/"// 2.定义一个 FileServerfs := http.FileServer(http.Dir("./static"))// 3.绑定 url 和 FileServerhttp.Handle(staticURL, http.StripPrefix(staticURL, fs))// 4.启动 HttpServer//err := http.ListenAndServe(":8080",nil)err := http.ListenAndServeTLS(":8081", "./conf/fullchain.pem", "./conf/privkey.pem", nil)if err != nil {fmt.Println(err)}
}

8. 编译程序

sh build.sh

#!/bin/bash
go build -o screen_share src/*

9. 启动程序

./screen_share

10. 使用 https 和端口 8081 访问页面成功

https://www.liangzixuexi.com:8081/static/share.html

但是现在只能通过 https 访问，原来的 http 不能访问了

11. 下面修改程序，支持 https 和 http 能同时访问

package mainimport ("fmt""net/http"
)func startHttp(port string){fmt.Printf("Start Http port: %s\n", port)err := http.ListenAndServe(port, nil)if err != nil {fmt.Println(err)}
}func startHttps(port, cert, key string){fmt.Printf("Start Https port: %s\n", port)err := http.ListenAndServeTLS(port, cert, key, nil)if err != nil {fmt.Println(err)}
}func main() {// 1.定义一个 URL 前缀staticURL := "/static/"// 2.定义一个 FileServerfs := http.FileServer(http.Dir("./static"))// 3.绑定 url 和 FileServerhttp.Handle(staticURL, http.StripPrefix(staticURL, fs))// 4.启动 HttpServer//err := http.ListenAndServe(":8080",nil)go startHttp(":8080")//err := http.ListenAndServeTLS(":8081", "./conf/fullchain.pem", "./conf/privkey.pem", nil)// 5.启动 HttpsServerstartHttps(":8081", "./conf/fullchain.pem", "./conf/privkey.pem")
}

12. 编译

sh build.sh

13. 启动程序

./screen_share

14. 使用 http 和 8080 端口访问成功

输入 http://www.liangzixuexi.com:8080/static/share.html

15. 使用 https 和 8081 端口访问成功

输入 https://www.liangzixuexi.com:8081/static/share.html
