在golang中将接口数组转换为map数组的最佳方法是什么？

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{})

?
