How do I get the local IP address in Go?

I want to get the computer's IP address. I used the code below, but it returns 127.0.0.1.

I want to get the IP address, such as 10.32.10.111, instead of the loopback address.

name, err := os.Hostname()
if err != nil {
     fmt.Printf("Oops: %v\n", err)
     return
}

addrs, err := net.LookupHost(name)
if err != nil {
    fmt.Printf("Oops: %v\n", err)
    return
}

for _, a := range addrs {
    fmt.Println(a)
}

You need to loop through all network interfaces

ifaces, err := net.Interfaces()
// handle err
for _, i := range ifaces {
    addrs, err := i.Addrs()
    // handle err
    for _, addr := range addrs {
        var ip net.IP
        switch v := addr.(type) {
        case *net.IPNet:
                ip = v.IP
        case *net.IPAddr:
                ip = v.IP
        }
        // process IP address
    }
}
