我正在建立一个网站,该网站将依赖 cookie 来处理各种事情。然后我决定有一个设置cookie然后读取相同cookie的功能,以查看浏览器是否允许cookie。但这失败了。
./views/index.html 中的模板
{{define "index"}}template{{end}}
主要代码:
package main
import (
"fmt"
"html/template"
"log"
"net/http"
"strconv"
"time"
"github.com/gorilla/handlers"
"github.com/gorilla/mux"
)
var tmpl *template.Template
func main(){
port :=":8088"
router := mux.NewRouter()
router.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
//Set test cookie
cookieName := strconv.FormatInt(time.Now().UnixNano(), 10)
cookieValue := strconv.FormatInt(time.Now().UnixNano(), 10)
fmt.Println("cookieName:" + cookieName)
fmt.Println("cookieValue:" + cookieValue)
cookie := http.Cookie{Name: cookieName, Value: cookieValue, Path: "/"}
http.SetCookie(w, &cookie)
//Get cookies
fmt.Println("Range over cookies")
for _, c := range r.Cookies() {
fmt.Println(c)
}
//Get test cookie by name
c, err := r.Cookie(cookieName)
if err != nil {
fmt.Println("Error: " + err.Error())
} else {
fmt.Println(c.Value)
}
err = tmpl.ExecuteTemplate(w, "index", "")
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
}
})
var err error
tmpl, err = template.ParseGlob("views/*")
if err != nil {
panic(err.Error())
}
router.PathPrefix("/").HandlerFunc(func(res http.ResponseWriter, req *http.Request) {
http.FileServer(http.Dir("./static/")).ServeHTTP(res, req)
})
fmt.Println("Server running on localhost" + port)
err = http.ListenAndServe(port, handlers.CompressHandler(router))
if err != nil {
log.Fatal(err)
}
}
这是终端输出:
Server running on localhost:8088
cookieName:1636243636497412077
cookieValue:1636243636497413613
Range over cookies
Error: http: named cookie not present
任何指向我的问题可能是什么?
