POST file and nested params golang - go

Question

I'm already posting a file and some params, but now I need to send nested params with a struct and I don't know where to use that (I'm new in Go).
This is what I have: https://play.golang.org/p/L4qx6AZhUO
Now, I'm creating this structs:
type S3 struct {
Accesskeyid string
Secretaccesskey string
Bucket string
}
type Test struct {
Outputformat string
Wait string
Output S3
File []byte
}
And I would like to send the Test struct WITH the file. Any ideas?
Thanks!

Okay, So given what you've told me and what little information I have with your example, I might do something like this.
package main
import (
"bytes"
"encoding/json"
"fmt"
"net/http"
)
type S3 struct {
Accesskeyid string
Secretaccesskey string
Bucket string
}
type Test struct {
Outputformat string
Wait string
Output S3
File []byte
}
func main() {
myStrut := Test{
Outputformat: "Json",
Wait: "Some Time",
Output: S3{
Accesskeyid: "my id",
Secretaccesskey: "secret id",
Bucket: "east",
},
File: []byte(`some bytes`),
}
jsonValue, err := json.Marshal(myStrut)
if err != nil {
panic(err)
}
fmt.Printf("Test showing that data was marshalled\n %q\n", jsonValue)
resp, err := http.Post("some url", "application/json", bytes.NewBuffer(jsonValue))
if err != nil {
panic(err)
}
fmt.Println(resp.Status)
}
Now from what i gleamed in the comments you might be also having trouble opening the file as a byte array to assign to your struct. Here's an example you can use you help you open the file as a byte array so that you can assign those bytes to your struct.
package main
import (
"fmt"
"io/ioutil"
)
func main() {
//An example of how to open a file and turn it into bytes for your struct
byteArray, err := ioutil.ReadFile("input.txt")
if err != nil {
panic(err)
}
fmt.Println(byteArray)
}
