Not able to set cookies in header

I am trying to set cookies from Go web server and then reading it in the chrome browser.

Here is my code 

package main

import (
    "fmt"
    "net/http"
    "time"
)


func setCookies(w http.ResponseWriter, r *http.Request){
    expiration := time.Now().Add(365 * 24 * time.Hour)
    c1 := http.Cookie{Name: "SpiderMan: Far from home",Value : "HollyWood", Path: "/", Expires: expiration, Secure: false}
    http.SetCookie(w,&c1)
    c2 := http.Cookie{Name: "Kabir Singh",Value: "BollyWood", Path: "/", Expires: expiration, Secure: false}
    http.SetCookie(w,&c2)

    // w.Header().Set("Set-Cookie",c1.String())
    // w.Header().Add("Set-Cookie",c2.String())
    // HttpOnly: true

    fmt.Fprintf(w, "")

}

func getCookies(w http.ResponseWriter, r *http.Request){
    // h := r.Header["Kabir Singh"]
    // fmt.Fprintln(w,h)

    c1, err := r.Cookie("Kabir Singh")
    if err != nil {
        fmt.Fprintln(w, "first_cookie is not set successfully." ,err)
    }
    ca := r.Cookies()
    fmt.Fprintln(w, c1)
    fmt.Fprintln(w, ca)
}

func main() {
    server := http.Server{
        Addr: "127.0.0.1:2020",
    }
    http.HandleFunc("/set_cookies", setCookies)
    http.HandleFunc("/get_cookies", getCookies)
    server.ListenAndServe()
}

After setting the cookies from call set_cookies when I am trying to get the cookies in the chrome browser I get this output:

first_cookie is not set successfully. http: named cookie not present

[]

I have read similar threads but none of it worked.

The problem you are having is caused by the name of your cookie. Adjust the names to not have whitespace and they will work as expected.

Example: 

c2 := http.Cookie{Name: "Kabir-Singh", Value: "BollyWood", Path: "/", Expires: expiration, Secure: false}

http.SetCookie(w, &c2)

It appears that you are not using valid cookie name. https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie

It mentions =>

A cookie-name can be any US-ASCII characters except control characters (CTLs), spaces, or tabs. It also must not contain a separator character like the following: ( ) < > @ , ; : \ " / [ ] ? = { }.

if you use cookie name as just Name: "SpiderMan" it should work.
