比较不区分大小写的字符串 (Comparing strings case insensitive)
Instead of runningToUpper()
orToLower()
from thestrings
orbytes
packages, usestrings.EqualFold()
orbytes.EqualFold()
, because they are guaranteed to work across all languages.
不要从strings
或bytes
包中运行ToUpper()
或ToLower()
,而是使用strings.EqualFold()
或bytes.EqualFold()
,因为可以保证它们可以在所有语言中使用。
package mainimport ("bytes""fmt")func main() {fmt.Println(bytes.EqualFold([]byte("Go"), []byte("go")))}
