How to parse parameters from POST body to map[string] string?

How to parse parameters from POST body to map[string] string?

I am using gin and I can parse to predefined structure but in this case I don't know key names. ( I can when I know key names but when I don't know is a problem )

type Body struct {
    Name    string
    Email   string
}

body := Body{}
err := json.NewDecoder( c.Request.Body ).Decode( &body )
if err != nil {
    c.String( http.StatusServiceUnavailable, err.Error() )
    return
}

The body looks like this:

{ 
"param1": "1", 
"param2": "1", 
"param3": "1", 
"param4": "1" 
}

Try this:

package main

import (
    "fmt"
    "encoding/json"
)


func main() {
    j := `{"foo": "aa", "baz": "bb", "qux": "cc"}`
    byt := []byte(j)

    var dat map[string]string   

    if err := json.Unmarshal(byt, &dat); err != nil {
            panic(err)
    }
    fmt.Println(dat)
}

Output:

map[qux:cc foo:aa baz:bb]
