我正在用 JavaScript 向我的 Go 服務器發出 POST 請求以發布一些 JSON 數據。后端成功接收數據。如果我控制臺記錄 promise 的結果，我會在調用fetchResponse.json()的行收到Unexpected end of JSON input error 。我不知道為什么會這樣。JavaScriptconst sendScore = async () => {    try {        const fetchResponse = await fetch(`http://localhost:8000/sendscore`, {            method: 'POST',            headers: {                'Accept': 'application/json',                'Content-Type': 'application/json'            },            body: JSON.stringify({name:"kris"})        });        const data = await fetchResponse.json();        return data;    } catch (e) {        return e;    }}const sendScoreBtn = document.querySelector("#sendScoreBtn");sendScoreBtn.addEventListener("click", () => {    console.log("Sending score...")    const res = sendScore()    res.then(console.log)})Go /sendscore 端點處理程序func recieveScore(w http.ResponseWriter, r *http.Request) {    var res playerScore    if err := json.NewDecoder(r.Body).Decode(&res); err != nil {        fmt.Println("Line 31", err)    }    fmt.Println("Res", res)}func main() {    // Serve static files(js, css)    http.Handle("/static/", http.StripPrefix("/static/", http.FileServer(http.Dir("./static"))))    http.HandleFunc("/", homePage)    http.HandleFunc("/sendscore", recieveScore)    fmt.Println("Server started. Listening on port :8000")    log.Fatal(http.ListenAndServe(":8000", nil))}
