如何在Golang中编码url参数？

Question

Is there any go package to encode url?I need to encode a parameter(type in map[string]interface{}) before it was transfered in url.

Maybe the parameter likes:map[string]interface{}{"app_id":"you_api","app_sign":"md5_base_16","timestamp":"1473655478000"} How to encode it and what the encoded result would be?

Answer 1

There is the one of method to get it.

package main

import (
    "fmt"
    "net/url"
    "encoding/json"
)

func main() {
    m := map[string]interface{}{"app_id": "you_api", "app_sign": "md5_base_16", "timestamp": "1473655478000"}
    json_str, _ := json.Marshal(m)
    fmt.Println(string(json_str[:]))

    values := url.Values{"para": {string(json_str[:])}}

    fmt.Println(values.Encode())

}
