regexp \S 的妙用

\S* vs .*​

  • *表数目
  • .表任意字符(包含空白字符，不含\n)范围更大
  • \S表非空字符，相对来说范围更小更精准
package main

var re = regexp.MustCompile(`"(\S*).github-scott-bear.workers.dev"`)

func main() {
    bs, _ := ioutil.ReadFile("config.json")
    arr := re.FindAllStringSubmatch(string(bs), -1)
    fmt.Println(arr[0][1]) //young-leaf-8425
