How to parse string into url.Values in golang? - parsing

Question

Let's suppose i have the following string
honeypot=&name=Zelalem+Mekonen&email=zola%40programmer.net&message=Hello+And+this+is+a+test+message...
and i want to convert it into url.Values struct and i have the following
data := url.Values{}
parameters := strings.Split(request.Body, "&")
for _, parameter := range parameters {
parts := strings.Split(parameter, "=")
data.Add(parts[0], parts[1])
}
which does convert it into url.Values but the problem is that it doesn't convert url encoded values like + into space, so first is there a better way to parse this? then if not how do i convert url encoded string to normal string first?
Thank's For Your Help...o

Answer 1

You could use url.ParseQuery to convert the raw query to url.Values with unescaping
package main
import (
"fmt"
"net/url"
)
func main() {
t := "honeypot=&name=Zelalem+Mekonen&email=zola%40programmer.net&message=Hello+And+this+is+a+test+message..."
v, err := url.ParseQuery(t)
if err != nil {
panic(err)
}
fmt.Println(v)
}
Result:
map[honeypot:[] name:[Zelalem Mekonen] email:[zola#programmer.net] message:[Hello And this is a test message...]]

Answer 2

You could first decode the URL with net/url/QueryUnescape.
It does converts '+' into '' (space).
Then you can start splitting the decoded string, or use net/url/#ParseRequestURI and get the URL.Query.

Answer 3

You can also use URL.Query:
package main
import (
"fmt"
"net/url"
)
func main() {
get := url.URL{
RawQuery: "honeypot=&name=Zelalem+Mekonen&email=zola%40programmer.net",
}
query := get.Query()
// map[email:[zola#programmer.net] honeypot:[] name:[Zelalem Mekonen]]
fmt.Println(query)
}
