+
func main() {
s1 := "hello"
s2 := "word"
s3 := s1 + s2
fmt.Print(s3) //s3 = "helloword"
}
sprintf
s1 := "hello"
s2 := "word"
s3 := fmt.Sprintf("%s%s", s1, s2) //s3 = "helloword"
Join
s1 := "hello"
s2 := "word"
var str []string = []string{s1, s2}
s3 := strings.Join(str, "")
fmt.Print(s3) //s3 = "helloword"
bytes.Buffer
s1 := "hello"
s2 := "word"
var bt bytes.Buffer
bt.WriteString(s1)
bt.WriteString(s2)
s3 := bt.String()
fmt.Println(s3)//s3 = "helloword"
strings.Builder
s1 := "hello"
s2 := "word"
var build strings.Builder
build.WriteString(s1)
build.WriteString(s2)
s3 := build.String()
fmt.Println(s3)//s3 = "helloword"
一般情况下我都是用+拼接，如果拼接的字符串比较长的话就是最后一种方式了
