Conversion between arrays and strings in go language

String conversion For the array

1. Creation of the array:

var endpoint = []string{"0.0.0.0:2379"}  //直接初始化数组
//数组 <<= string
IPAddresses := []string{leftIP}

2. Directly writing into the empty array:

 etcd :="sdfsdferf"
 stringarr := make([]string, 0)      //创建空数组
 stringarr = append(stringarr, etcd)
 /*stringarr = append(stringarr, "456")*/
 println("*****")
 for _, str := range stringarr {
   println(str)
 }
 println("*****")

How to convert the array into a string

1. Convert an element in the array directly into a string

 arr := make([]string, 0) 
 arr[0] = "sfsdfsdf"
 string := arr[0]  //直接将该数组的一个元素，赋值给字符串
 fmt.Printf("====>:%s\n", string)

2. Convert all the data in the array into a string

func arrayToString(arr []string) string {
   var result string
   for _, i := range arr {  //遍历数组中所有元素追加成string
    result += i
   }
   return result
   }
