我正在計(jì)算 golang 中的日期差異，我已經(jīng)編寫了代碼并且它執(zhí)行得很好但是當(dāng)我以分鐘為單位計(jì)算時(shí)間差異時(shí)，將其轉(zhuǎn)換為整數(shù)并在 if 條件下進(jìn)行比較。我正在嘗試的代碼根據(jù)以下條件，它不應(yīng)打印“diffinmin is greater P”，但它正在打印。我哪里做錯(cuò)了？package mainimport ( "fmt" "time" "strconv")func main() { //fetching current time currentTime := time.Now() loc := currentTime.Location() //past time comes in as string pasttimestr := "2018-10-18 01:00" layout := "2006-01-02 15:04" //converting string to date pasttime, err := time.ParseInLocation(layout, pasttimestr, loc) if err != nil { fmt.Println(err) } fmt.Println("Past Time: ", pasttime) fmt.Println("Current Time: ", currentTime) //differnce between pastdate and current date diff := currentTime.Sub(pasttime) var diffinmin int = int(diff.Minutes()) fmt.Printf( "heloo",diffinmin ) fmt.Printf("time difference is %v or %v in minutes\n", diff, diff.Minutes()) var strconfigtime = "9000" var mininttimeconfig int if mininttimeconfig, err := strconv.Atoi(strconfigtime); err == nil { fmt.Printf("i=%d, type: %T\n", mininttimeconfig, mininttimeconfig) } if diffinmin > mininttimeconfig { fmt.Printf("diffinmin is greater" ) }}小提琴：https://play.golang.org/p/x6-RebYycpk

它是關(guān)于范圍的，您在檢查中使用的 mininttimeconfig 的值為 0。
if mininttimeconfig, err := strconv.Atoi(strconfigtime); err == nil {
// mininttimeconfig is a new variable scoped to this block
}
// here mininttimeconfig is 0 from declaration line
// var mininttimeconfig int
嘗試將行更改為：
var mininttimeconfig int
mininttimeconfig, err = strconv.Atoi(strconfigtime);
if err == nil {
// ...
或者：
mininttimeconfig, err := strconv.Atoi(strconfigtime);
if err == nil {
// ...
注意通常使用 error 就像 if err != nil {...}
