How to translate this curl call into Go? - go

Question

I have the following curl call:
curl \
--request POST \
--header "Content-Type: application/x-www-form-urlencoded" \
--header "Authorization: Basic XXXX" \
--data-urlencode 'A=B' \
--data-urlencode 'C=D' \
"https://www.myexample.com/mypath?param1=foobar"
How can I write Go code that will do the exact same thing?
So far, I have successfully constructed the full URL and am sending it to http.NewRequestWithContext()
u, err := url.Parse("https://www.myexample.com" + "/mypath")
if err != nil {
return err
}
q := u.Query()
u.RawQuery = q.Encode()
http.NewRequestWithContext(myContext, http.MethodPost, u.String(), nil)
response, err := http.NewRequestWithContext(myContext, http.MethodPost, s.cfg.BaseDRAPI + oAuthPath, nil)
if err != nil {
return err
}
However, I do not know where/how to specify the headers and the two data fields.
Please help!

Create the request and send it as below. Handle the error and response according to your application.
endpoint := "https://www.myexample.com/mypath?param1=foobar"
data := url.Values{}
data.Set("A", "B")
data.Set("C", "D")
//create new POST request to the url and encoded form Data
r, err := http.NewRequest("POST", endpoint, strings.NewReader(data.Encode())) // URL-encoded payload
if err != nil {
log.Fatal(err)
}
//set headers to the request
r.Header.Add("Content-Type", "application/x-www-form-urlencoded") //this is a must for form data encoded request
r.Header.Add("Authorization", "Basic XXXX")
//send request and get the response
client := &http.Client{}
res, err := client.Do(r)
if err != nil {
//handle error
log.Fatal(`error: `,err)
}
log.Println(res.Status)
//handle response part here
