golang简单tls协议用法完整示例
2018-09-22 01:13
本文实例讲述了golang简单tls协议用法。分享给大家供大家参考,具体如下:
生成私钥:
openssl genrsa -out key.pem 2048
生成证书:
openssl req -new -x509 -key key.pem -out cert.pem -days 3650
https:
复制代码 代码如下:package main
import (
io
net/http
log
)
func HelloServer(w http.ResponseWriter, req *http.Request) {
io.WriteString(w, hello, world!\n)
}
func main() {
http.HandleFunc(/hello, HelloServer)
err := http.ListenAndServeTLS(:8080, cert.pem, key.pem, nil)
if err != nil {
log.Fatal(ListenAndServe: , err)
}
}
提示: 访问请勿忘记使用https开头,否则chrome会下载一个文件如下:
dotcoo-air:tls dotcoo$ cat /Users/dotcoo/Downloads/hello xxd
0000000: 1503 0100 0202 0a .......
TLS Server:
复制代码 代码如下:package main
import (
log
crypto/tls
net
bufio
)
func main() {
log.SetFlags(log.Lshortfile)
cer, err := tls.LoadX509KeyPair(cert.pem, key.pem)
if err != nil {
log.Println(err)
return
}
ln, err := tls.Listen(tcp, :8000, config)
if err != nil {
log.Println(err)
return
}
defer ln.Close()
for {
conn, err := ln.Accept()
if err != nil {
log.Println(err)
continue
}
go handleConnection(conn)
}
}
func handleConnection(conn net.Conn) {
defer conn.Close()
r := bufio.NewReader(conn)
for {
msg, err := r.ReadString(\n)
if err != nil {
log.Println(err)
return
}
println(msg)
n, err := conn.Write([]byte(world\n))
if err != nil {
log.Println(n, err)
return
}
}
}
TLS Client:
复制代码 代码如下:package main
import (
log
crypto/tls
)
func main() {
log.SetFlags(log.Lshortfile)
InsecureSkipVerify: true,
}
conn, err := tls.Dial(tcp, 127.0.0.1:8000, conf)
if err != nil {
log.Println(err)
return
}
defer conn.Close()
n, err := conn.Write([]byte(hello\n))
if err != nil {
log.Println(n, err)
return
}
buf := make([]byte, 100)
n, err = conn.Read(buf)
if err != nil {
log.Println(n, err)
return
}
println(string(buf[:n]))
}
希望本文所述对大家Go语言程序设计有所帮助。
