1-使用_, after, _ = strings.Cut(ms, p),试试这个:
func removeFromPattern(p, ms string) (after string) {
_, after, _ = strings.Cut(ms, p) // before and after sep.
return
}
哪个用途strings.Index:
// Cut slices s around the first instance of sep,
// returning the text before and after sep.
// The found result reports whether sep appears in s.
// If sep does not appear in s, cut returns s, "", false.
func Cut(s, sep string) (before, after string, found bool) {
if i := Index(s, sep); i >= 0 {
return s[:i], s[i+len(sep):], true
}
return s, "", false
}
2-使用strings.Index,试试这个:
func removeFromPattern(p, ms string) string {
i := strings.Index(ms, p)
if i == -1 {
return ""
}
return ms[i+len(p):]
}
3-使用strings.Split,试试这个:
func removeFromPattern(p, ms string) string {
a := strings.Split(ms, p)
if len(a) != 2 {
return ""
}
return a[1]
}
4-使用regexp,试试这个
func removeFromPattern(p, ms string) string {
a := regexp.MustCompile(p).FindStringSubmatch(ms)
if len(a) < 2 {
return ""
}
return a[1]
}

func main() {
pattern := "helloworld."
myString := "foo.bar.helloworld.qwerty.zxc"
res := removeFromPattern(pattern, myString)
fmt.Println(res)
}
func removeFromPattern(p, ms string) string {
parts := strings.Split(ms, p)
if len(parts) > 1 {
return parts[1]
}
return ""
}
