補(bǔ)充：golang中的正則匹配&判斷元素是否在slice里或者數(shù)組里
1、正則匹配

package main import ( "fmt" "regexp") func main() { //pattern := "\\d+" //反斜杠要轉(zhuǎn)義 pattern := "[a-zA-Z]" //匹配字母 str := "a1.22.35.4" result, _ := regexp.MatchString(pattern, str) fmt.Println(result) //true} |

package main import "fmt" import "github.com/wxnacy/wgo/arrays" //go get github.com/wxnacy/wgo/arrays 安裝包 func main() { str := "342" var numbers []string numbers = append(numbers, "3332", "342", "ssddd", "ssss", "%%%%") index := arrays.ContainsString(numbers, str) if index == -1 { fmt.Printf("not exists") //-1說(shuō)明不存在 } else { fmt.Println(index) //存在則會(huì)返回元素的下標(biāo) }} |
以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持服務(wù)器之家。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教。
