package main
import (
    "fmt"
    "strings"
)
func testHasPrefix()  {
    /**
    判断前缀是否以xx开头
     */
    str := "http://baidu.com"
    if strings.HasPrefix(str,"http"){
        fmt.Println("str is http url")
    }else {
        fmt.Println("str is not http url")
    }
}
func testHasSuffix()  {
    //判断是否以xx结束
    str := "http://baidu.com"
    if strings.HasSuffix(str,"baidu.com"){
        fmt.Println("str is baidu url")
    }else {
        fmt.Println("str is not baidu url")
    }
}
func main()  {
    testHasPrefix()
    testHasSuffix()
}

输出:

str is http url
