如何访问http客户端响应体全局

在下面的代码中，我试图将变量“Regprofile”作为全局变量访问，但得到的输出为空。有什么帮助吗

type GMLCInstance struct {
    NfInstanceID   string   `json:"nfInstanceID"`
    HeartBeatTimer int      `json:"heartBeatTimer"`
    NfType         []string `json:"nfType"`
    NfStatus       []string `json:"nfStatus"`
    Ipv4Addresses  []string `json:"ipv4Addresses"`
}


var Regprofile GMLCInstance


// Request credentials and token from NRF and register profile to NFR database
func init() {

    urlcred := "https://127.0.0.1:9090/credentials"

    // Perform the request
    resp, err := netClient.Get(urlcred)
    if err != nil {
        log.Fatalf("Failed get: %s", err)
    }
    defer resp.Body.Close()

    // Fill the record with the data from the JSON
    var cr Credential

    // Use json.Decode for reading streams of JSON data
    if err := json.NewDecoder(resp.Body).Decode(&cr); err != nil {
        log.Println(err)
    }

    //fmt.Println(cr)

    clientId := cr.CLIENTID
    clientsec := cr.CLIENTSECRET

    // Get token

    reqtoken := url.Values{
        "grant_type":    []string{"client_credentials"},
        "client_id":     []string{clientId},
        "client_secret": []string{clientsec},
        "scope":         []string{"GMLC"},
    }

    urlq := "https://127.0.0.1:9090/oauth2/token?"

    res, err := netClient.PostForm(urlq+reqtoken.Encode(), nil)
    if err != nil {
        log.Fatalf("Failed get: %s", err)
    }


    var auth AccessToken

    // Use json.Decode for reading streams of JSON data
    if err := json.NewDecoder(res.Body).Decode(&auth); err != nil {
        log.Println(err)
    }

    //fmt.Println(auth.AccessToken)

    token := auth.AccessToken

    para := url.Values{
        "access_token": []string{token},
    }

    //============================================================
    // Register GMLC Instance to NRF, PUT

    var gmlc = []byte(`{
                "nfInstanceID": "f81d4fae-7dec-11d0-a765-00a0c91egmlc",
                "heartBeatTimer": 0,
                "nfType": ["GMLC"],
                "nfStatus": ["string"],
                "ipv4Addresses": ["172.16.0.X:5000"]
               }`)

    //================= Registser profile to NRF ========================//
    postnrf := "https://127.0.0.1:9090/nnrf-nfm/v1/nf-instances/f81d4fae-7dec-11d0-a765-00a0c91egmlc?"
    rq, err := http.NewRequest("PUT", postnrf+para.Encode(), bytes.NewBuffer(gmlc))
    rq.Header.Set("Content-Type", "application/json")
    rq.Header.Set("Accept", "application/json")

    response, err := netClient.Do(rq)
    if err != nil {
        panic(err)
    }
    defer res.Body.Close()

    decoder := json.NewDecoder(response.Body)

    var Regprofile GMLCInstance

    err = decoder.Decode(&Regprofile)
    if err != nil {
        fmt.Println("Response body not well decoded")
    }

    fmt.Println(Regprofile)

}

fmt.Println（Regprofile）的输出给出 {f81d4fae-7dec-11d0-a765-00a0c91egmlc 10[GMLC][已注册][172.16.0.X:5000]}

但是，当我在例如main中打印变量时

func main(){

fmt.Println(Regprofile)

}

我得到的是空数据 {0[][]]}

在

func init（）

中，您将变量

var Regprofile GMLCInstance

本地重新声明到函数范围。此声明将全局变量与局部变量隐藏在一起。只需在

init（）

中删除此本地声明
