如何從 Golang 中的 JSON HTTP 回應中提取'ip”值？

import (
    "bytes"
    "encoding/json"
    "fmt"
    "log"
)

// Define structs to match the JSON structure
type Example struct {
    Type    string   `json:"type"`
    Subsets []Subset `json:"subsets"`
}

type Subset struct {
    Addresses []Address `json:"addresses"`
}

type Address struct {
    IP string `json:"ip"`
}

func main() {
    // Define the JSON input
    m := []byte(`{"type":"example","data":{"name":"abc","labels":{"key":"value"}},"subsets":[{"addresses":[{"ip":"192.168.103.178"}],"ports":[{"port":80}]}]}`)

    // Create a reader from the JSON input
    r := bytes.NewReader(m)
    decoder := json.NewDecoder(r)

    // Decode the JSON into the Example struct
    val := &Example{}
    if err := decoder.Decode(val); err != nil {
        log.Fatal(err)
    }

    // Iterate over the Subsets and Addresses slices to access each IP
    for _, s := range val.Subsets {
        for _, a := range s.Addresses {
            fmt.Println(a.IP)
        }
    }
}
