golang 数组去重，利用map

可以利用go中，map数据类型的key唯一的属性，来对数组去重
将strSlice数组中重复的元素去掉，使其中的元素唯一

var strMap make(map[string]string)
strSlice := []string {"slice","int","string","int","boolean","string"}
for _,v:= range strSlice{
	strMap[value] = v
}
//strMap为：{"slice"："slice","int"："int","string"："string","boolean"：boolean"}
//如果想将map转换为slice，可利用数组的append函数
var secondStr []string
for _,value := range strMap{
	secondStr = append(secondStr ,value)
}
//secondStr为：{"slice","int","string","boolean"}
