golang tls协议 golang简单tls协议用法完整示例
dotcoo 人气:3想了解golang简单tls协议用法完整示例的相关内容吗，dotcoo在本文为您仔细讲解golang tls协议的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：golang,tls协议，下面大家一起来学习吧。
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)
}
}
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
}
config := &tls.Config{Certificates: []tls.Certificate{cer}}
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
}
}
}
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
}
config := &tls.Config{Certificates: []tls.Certificate{cer}}
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)
conf := &tls.Config{
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]))
}
import (
"log"
"crypto/tls"
)
func main() {
log.SetFlags(log.Lshortfile)
conf := &tls.Config{
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]))
}
