here my code
package main
import (
"fmt"
"io/ioutil"
"net/http"
"os"
)
func getbalance(address string) string {
response, err := http.Get("https://blockchain.info/q/addressbalance/" + address)
if err != nil {
fmt.Printf("%s", err)
os.Exit(1)
} else {
defer response.Body.Close()
contents, err := ioutil.ReadAll(response.Body)
if err != nil {
fmt.Printf("%s", err)
os.Exit(1)
}
fmt.Printf("%s\n", string(contents))
return string(contents)
}
}
func main() {
finalB := getbalance("1A63imbiQBtsnTqtUpuUT5WL2Ti7oKNLeg")
fmt.Printf("Final Balance: %s", finalB)
}
return .\test.go:25:1: missing return at end of function
why ?

getbalance
is missing a final return
statement.
Currently the compiler thinks, that in case of err != nil
you do not return
anything, as it con not see through os.Exit()
.
A more sane solution would probably be to not have the else
branch, but keep it “inline”:
func getbalance(address string) string {
response, err := http.Get("https://blockchain.info/q/addressbalance/" + address)
if err != nil {
fmt.Printf("%s", err)
os.Exit(1)
}
defer response.Body.Close()
contents, err := ioutil.ReadAll(response.Body)
if err != nil {
fmt.Printf("%s", err)
os.Exit(1)
}
fmt.Printf("%s\n", string(contents))
return string(contents)
}
thank you very much i see your code for anderstand
