Auto TLS

这个例子演示如何自动从 Let’s Encrypt 获得 TLS 证书。Echo#StartAutoTLS接受一个接听 443 端口的网络地址。类似<DOMAIN>:443这样。

如果没有错误，访问https://<DOMAIN>，可以看到一个 TLS 加密的欢迎界面。

服务器

server.go

package main

import
(
"net/http"
"github.com/labstack/echo"
"github.com/labstack/echo/middleware"
)
func main()
{
    e := echo.New()
    // e.AutoTLSManager.HostPolicy = autocert.HostWhitelist("<your_domain>")
    // Store the certificate to avoid issues with rate limits (https://letsencrypt.org/docs/rate-limits/)
    // e.AutoTLSManager.Cache = autocert.DirCache("<path to store key and certificate>")
    e.Use(middleware.Recover())
    e.Use(middleware.Logger())
    e.GET("/",func(c echo.Context) error{
        return c.HTML(http.StatusOK, 
            `<h1>Welcome to Echo!</h1>
            <h3>TLS certificates automatically installed from Let's Encrypt :)</h3>`)
        })
    e.Logger.Fatal(e.StartAutoTLS(":443"))
}
