Go中函数重载的替代方法？

Question

是否可以使用Golang以类似的方式工作，例如函数重载或C＃中的可选参数？还是另一种方式？

Answer 1

Go中可选参数的惯用答案是包装函数：func do(a, b, c int) {    // ...}func doSimply(a, b) {    do(a, b, 42)}有意避免了函数重载，因为它使代码难以阅读。

Answer 2

有一些提示，这里使用可变参数，例如：sm1 := Sum(1, 2, 3, 4) // = 1 + 2 + 3 + 4 = 10sm2 := Sum(1, 2) // = 1 + 2 = 3sm3 := Sum(7, 1, -2, 0, 18) // = 7 + 1 + -2 + 0 + 18 = 24sm4 := Sum() // = 0func Sum(numbers ...int) int {&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; n := 0&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; for _,number := range numbers {&nbsp; &nbsp; &nbsp; &nbsp; n += number&nbsp; &nbsp; }&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; return n}或...interface{}任何类型：Ul("apple", 7.2, "BANANA", 5, "cHeRy")func Ul(things ...interface{}) {&nbsp; fmt.Println("<ul>")&nbsp; &nbsp;&nbsp;&nbsp; for _,it := range things {&nbsp; &nbsp; fmt.Printf("&nbsp; &nbsp; <li>%v</li>\n", it)&nbsp; }&nbsp; &nbsp;&nbsp;&nbsp; fmt.Println("</ul>")}
