golAng怎么将intErFACE转为string类型?

package mainimport "fmt"func main() {var a interface{}var b stringa = "asdasdasdasd"b = a.(string)fmt.Println(a, b) package mainimport ( "fmt""strings")func getName(params ...interface{}) {aa := strings.Join([]string(params), '...

var src []map[string]string var dest []map[string]interface{} for i := range src { m := src[i] n := make(map[string]interface{}) for k,v := range m { n[k] = interface{}(v) } dest = append(dest, n) }

给你个fmt.Printf的例子: echo 函数不定参数,其调用fmt.Printf进行输出,因为v是一个slice,所以传递给fmt.Printf的时候需要 v...,就类似append(slice1,slice2...) package main import ( "fmt" ) func main() { echo("Hello %s, I am %s\n",...

var src []map[string]string var dest []map[string]interface{} for i := range src { m := src[i] n := make(map[string]interface{}) for k,v := range m { n[k] = interface{}(v) } dest = append(dest, n) }

package mainimport "fmt"func main() {var a interface{}var b stringa = "asdasdasdasd"b = a.(string)fmt.Println(a, b) package mainimport ( "fmt""strings")func getName(params ...interface{}) {aa := strings.Join([]string(params), '...

Golang的interface,和别的语言是不同的。它不需要显式的implements,只要某个struct实现了interface里的所有函数,编译器会自动认为它实现了这个interface。 SICP里详细解释了为什么同一个接口,需要根据不同的数据类型,
