Go语言String字符串高效拼接

Go语言字符串如何高效的进行拼接

1. 原生拼接方式"+"

    var s string
    s += "AAA"
    s += "BBB"
   

2. 切片append

   var s string
   s = string(append([]byte(s), "AAA"...))
   s = string(append([]byte(s), "BBB"...))
   fmt.Println(s)
   

3. 字符串格式化函数fmt.Sprintf

    str := "AAA"
    str = fmt.Sprintf("%s%s", str, str)
   

4. Strings.builder

    var builder strings.Builder
    builder.WriteString("AAA")
    builder.WriteString("BBB")
    builder.String()
   

5. bytes.Buffer

    buf := new(bytes.Buffer)
    builder.WriteString("AAA")
    builder.WriteString("BBB")
    buf.String()
   

6. strings.join

    strs := []string{"AAA"}
    strings.Join(strs, "BBB")
