Go语言获取文件的名称、前缀、后缀

package main
import (
    "fmt"
    "path"
)
func main() {
    filename := "device/sdk/CMakeLists.txt"
    filenameall := path.Base(filename)    
    filesuffix := path.Ext(filename)
    fileprefix := filenameall[0:len(filenameall) - len(filesuffix)]
    //fileprefix, err := strings.TrimSuffix(filenameall, filesuffix)
    fmt.Println("file name:", filenameall)
    fmt.Println("file prefix:", fileprefix)
    fmt.Println("file suffix:", filesuffix)
}

执行结果：

file name: CMakeLists.txt

file prefix: CMakeLists

file suffix: .txt

path.Base(filename) 

path.Ext(filename) 

fileprefix := filenameall[0:len(filenameall) - len(filesuffix)]

import "strings"
fileprefix, err := strings.TrimSuffix(filenameall, filesuffix)

补充：golang 判断前缀后缀、包含关系

strings.HasPrefix(s, prefix string) bool

strings.HasSuffix(s, suffix string) bool

Contains 判断字符串 s 是否包含 substr ：

strings.Contains(s, substr string) bool

package main
import (
        "fmt"
        "strings"
)
func main() {
        var str1 string = "This is an example of a string"
        var str2 string = "this is an "
        var str3 string = " of a string"
        fmt.Println(strings.HasPrefix(str1, str2))
        fmt.Println(strings.HasSuffix(str1, str3))
}

运行结果：

[root@localhost golang]# Go run zzz.go

false

true
