golang简单tls协议用法完整示例
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：
opensslgenrsa-outkey.pem2048
生成证书：
opensslreq-new-x509-keykey.pem-outcert.pem-days3650
https：
packagemain
import(
"io"
"net/http"
"log"
)
funcHelloServer(whttp.ResponseWriter,req*http.Request){
io.WriteString(w,"hello,world!\n")
}
funcmain(){
http.HandleFunc("/hello",HelloServer)
err:=http.ListenAndServeTLS(":8080","cert.pem","key.pem",nil)
iferr!=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:tlsdotcoo$cat/Users/dotcoo/Downloads/hello|xxd
0000000:1503010002020a .......
TLSServer：
packagemain
import(
"log"
"crypto/tls"
"net"
"bufio"
)
funcmain(){
log.SetFlags(log.Lshortfile)
cer,err:=tls.LoadX509KeyPair("cert.pem","key.pem")
iferr!=nil{
log.Println(err)
return
}
config:=&tls.Config{Certificates:[]tls.Certificate{cer}}
ln,err:=tls.Listen("tcp",":8000",config)
iferr!=nil{
log.Println(err)
return
}
deferln.Close()
for{
conn,err:=ln.Accept()
iferr!=nil{
log.Println(err)
continue
}
gohandleConnection(conn)
}
}
funchandleConnection(connnet.Conn){
deferconn.Close()
r:=bufio.NewReader(conn)
for{
msg,err:=r.ReadString('\n')
iferr!=nil{
log.Println(err)
return
}
println(msg)
n,err:=conn.Write([]byte("world\n"))
iferr!=nil{
log.Println(n,err)
return
}
}
}
TLSClient：
packagemain
import(
"log"
"crypto/tls"
)
funcmain(){
log.SetFlags(log.Lshortfile)
conf:=&tls.Config{
InsecureSkipVerify:true,
}
conn,err:=tls.Dial("tcp","127.0.0.1:8000",conf)
iferr!=nil{
log.Println(err)
return
}
deferconn.Close()
n,err:=conn.Write([]byte("hello\n"))
iferr!=nil{
log.Println(n,err)
return
}
buf:=make([]byte,100)
n,err=conn.Read(buf)
iferr!=nil{
log.Println(n,err)
return
}
println(string(buf[:n]))
}
