Jetbrains全系列IDE使用 1年只要46元 售后保障 童叟无欺
1- You may write your conversion function (Fastest):
func String(n int32) string {
buf := [11]byte{}
pos := len(buf)
i := int64(n)
signed := i < 0
if signed {
i = -i
}
for {
pos--
buf[pos], i = '0'+byte(i%10), i/10
if i == 0 {
if signed {
pos--
buf[pos] = '-'
}
return string(buf[pos:])
}
}
}
2- You may use fmt.Sprint(i) (Slow)
See inside:
// Sprint formats using the default formats for its operands and returns the resulting string.
// Spaces are added between operands when neither is a string.
func Sprint(a ...interface{}) string {
p := newPrinter()
p.doPrint(a)
s := string(p.buf)
p.free()
return s
}
3- You may use strconv.Itoa(int(i)) (Fast)
See inside:
// Itoa is shorthand for FormatInt(int64(i), 10).
func Itoa(i int) string {
return FormatInt(int64(i), 10)
}
4- You may use strconv.FormatInt(int64(i), 10) (Faster)
See inside:
// FormatInt returns the string representation of i in the given base,
// for 2 <= base <= 36. The result uses the lower-case letters 'a' to 'z'
// for digit values >= 10.
func FormatInt(i int64, base int) string {
_, s := formatBits(nil, uint64(i), base, i < 0, false)
return s
}

本人自用代码:
func Test_conver(t *testing.T) {
var stairName string
s := "test886400"
id := int32(886400)
iDStr := strconv.FormatInt(int64(id), 10)
if strings.Contains(s, iDStr) {
stairName = strings.TrimSuffix(s, iDStr)
}
fmt.Println("stairName:", stairName)
}
效果如下:
