在go中将url.Values 类型进行url encode使用函数url.Values.Encode()
url decode 使用 url.ParseQuery(string)

package main

import (
    "fmt"
    "net/url"
)

func main() {
    // url encode
    v := url.Values{}
    v.Add("a", "aa")
    v.Add("b", "bb")
    v.Add("c", "有没有人")
    body := v.Encode()
    fmt.Println(v)
    fmt.Println(body)
    // url decode
    m, _ := url.ParseQuery(body)
    fmt.Println(m)
}
``
map[a:[aa] b:[bb] c:[有没有人]]
a=aa&b=bb&c=%E6%9C%89%E6%B2%A1%E6%9C%89%E4%BA%BA
map[b:[bb] c:[有没有人] a:[aa]]



// Encode encodes the values into ``URL encoded'' form
// ("bar=baz&foo=quux") sorted by key.
// 以URL encoded方式编码values并按key进行排序
func (v Values) Encode() string {
    if v == nil {
        return ""
    }
    var buf bytes.Buffer
    keys := make([]string, 0, len(v))
    for k := range v {
        keys = append(keys, k)
    }
    sort.Strings(keys)
    for _, k := range keys {
        vs := v[k]
        prefix := QueryEscape(k) + "="
        for _, v := range vs {
            if buf.Len() > 0 {
                buf.WriteByte('&')
            }
            buf.WriteString(prefix)
            buf.WriteString(QueryEscape(v))
        }
    }
    return buf.String()
}



// ParseQuery parses the URL-encoded query string and returns
// a map listing the values specified for each key.
// ParseQuery always returns a non-nil map containing all the
// valid query parameters found; err describes the first decoding error
// encountered, if any.
//
// Query is expected to be a list of key=value settings separated by
// ampersands or semicolons. A setting without an equals sign is
// interpreted as a key set to an empty value.
// 解析URL-encoded编码的字符串，按照key=value方式解析并构造map，没有=号的解析为key并设置值为空
func ParseQuery(query string) (Values, error) {
    m := make(Values)
    err := parseQuery(m, query)
    return m, err
}
