我正在用 JavaScript 向我的 Go 服务器发出 POST 请求以发布一些 JSON 数据。后端成功接收数据。
如果我控制台记录 promise 的结果,我会在调用fetchResponse.json()的行收到Unexpected end of JSON input error 。我不知道为什么会这样。
JavaScript
const 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 端点处理程序
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))
}
