在golang中将接口数组转换为map数组的最佳方法是什么？

Question

I've created a web server and this server is able to get POST request. However, when I send array of map[string]string in POST data, server receives it as array of interface{}. How can I convert it back to array of map[string]string?

Example : Like when I send following example in POST request,

params : [{"name" : "shail", "age" : 24}]

I'm sending params as

[](map[string]string)

but when server receives this data, it treats params as

[]interface{}

.How do I assign params in a variable defined by

[](map[string]interface{})

?

The easiest thing you can do is a type assertion on the values:

package main

import (
    "fmt"
    "reflect"
)

func main() {
    var source []interface{}
    var test = make(map[string]string, 0)
    test["hello"] = "World"
    source = append(source, test)
    var dest = source[0].(map[string]string)
    fmt.Println(reflect.TypeOf(dest).Kind())
    fmt.Println(dest["hello"])
}
