func sayHelloHandler(w http.ResponseWriter, r *http.Request) {
SetCookie(w, r)
//fmt.Fprintf(w, "Hello world!\n") //这个写入到w的是输出到客户端的
}
func main() {
http.HandleFunc("/", sayHelloHandler) // 设置访问路由
log.Fatal(http.ListenAndServe(":8080", nil))
}
func SetCookie(w http.ResponseWriter, r *http.Request) {
ck := &http.Cookie{
Name: "name",
Value: "hello",
Path: "/",
Domain: "localhost",
MaxAge: 120,
}
w.Header().Set("set-cookie", ck.String()) //设置cookie value 值可以包含空格
//http.SetCookie(w, ck) //设置cookie value 值可以不能包含空格
}读取cookie
cookie, err := r.Cookie("name")
if err == nil {
fmt.Println(cookie.Value)
