你可能很少花精力来解决这个问题。虽然我很无聊，所以我决定帮助你。这是您的后端：
package main
import (
"encoding/json"
"fmt"
"log"
"net/http"
"time"
)
type Response struct {
CurrentTime string
}
func main() {
http.Handle("/", http.FileServer(http.Dir("web")))
http.HandleFunc("/get-time", func(rw http.ResponseWriter, r *http.Request) {
ctime := Response{
CurrentTime: time.Now().Format(time.RFC3339),
}
byteArray, err := json.Marshal(ctime)
if err != nil {
fmt.Println(err)
}
rw.Write(byteArray)
})
if err := http.ListenAndServe(":5000", nil); err != nil {
log.Fatal(err)
}
}
您还需要位于 （web/index.html） 中的前端：
<!DOCTYPE html>

<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<button id="gt">get time</button>
<div id="res"></div>
<script>
document.getElementById("gt").onclick = async (e) => {
var req = await fetch("\get-time").then(r => r.json())
document.getElementById("res").innerHTML = req.CurrentTime
}
</script>
</body>
</html>
