我有點想知道為什么下面的代碼確實有效：var serverStartedTime time.Time // Holds the time since the server is started.type ServerInformation struct {    Uptime ServerUptimeInformation `json:"uptime"`}type ServerUptimeInformation struct {    Hours       int64 `json:"hours"`    Minutes     int64 `json:"minutes"`    Seconds     int64 `json:"seconds"`    NanoSeconds int64 `json:"nanoSeconds"`}func main() {    serverStartedTime = time.Now()    http.HandleFunc("/api/v1/health", getHealthHandler)    log.Fatal(http.ListenAndServe(":8000", nil))}func handler(writer http.ResponseWriter, request *http.Request) {    fmt.Fprintf(writer, "URL.Path = %q\n", request.URL.Path)}func getHealthHandler(writer http.ResponseWriter, request *http.Request) {    serverUptime := time.Now().Sub(serverStartedTime)    hours := int64(serverUptime.Hours())    minutes := int64(serverUptime.Minutes()) - (hours * 60)    seconds := int64(serverUptime.Seconds()) - (hours * 60) - (minutes * 60)    nanoSeconds := int64(serverUptime.Nanoseconds()) - (hours * 60) - (minutes * 60) - (seconds * 1000000000)    serverInformation := ServerInformation{        ServerUptimeInformation{            hours, minutes, seconds, nanoSeconds,        },    }    returnJSON(writer, serverInformation)}func returnJSON(writer http.ResponseWriter, data ...interface{}) {    dataJSON, marshalError := json.Marshal(data)    if marshalError != nil {        writer.WriteHeader(http.StatusInternalServerError)    } else {        writer.WriteHeader(http.StatusOK)        writer.Header().Set("Content-Type", "application/json")        writer.Write(dataJSON)    }}默認情況下，Go 復(fù)制提供給方法的參數(shù)。因此，“/api/v1/health”的 HTTP 處理程序確實需要一個編寫器，我們將其傳遞給該returnJSON方法。因此，此方法確實收到了它寫入的副本。我怎么會在我的瀏覽器中看到響應(yīng)？沒想到作者被抄襲了。
