如何解析QueryString

I have a string such as username=Test1234&currency=THB and I need to get value of username or currency

qry, _ := url.Parse(string(qryString))

An example is as follows:

package main

import (
    "fmt"
    "net/url"
)

func main() {
    address := "http://example.com?name=poloxue&age=11"

    u, err := url.Parse(address)
    if err != nil {
        panic(err)
    }
    fmt.Println(u.RawQuery)

    q, err := url.ParseQuery(u.RawQuery)
    if err != nil {
        panic(err)
    }

    fmt.Println(q.Get("name"))
}

Output:

name=poloxue&age=11
poloxue
