Question

我只是学习Go，然后将Echo Golang用于我的Framework。然后我开始专门为Google学习Oauth2，但是出现了问题，我不知道是哪种错误

package controller

import (
    "fmt"
    "io/ioutil"
    "net/http"

    "github.com/labstack/echo"
    "github.com/spf13/viper"
    "golang.org/x/oauth2"
    "golang.org/x/oauth2/google"
)

//HELPER
var (
    googleOauthConfig *oauth2.Config
    oauthStateString  = "pseudo-random"
    oauthGoogleURLAPI = "https://www.googleapis.com/oauth2/v2/userinfo?access_token="
)

func initGoogleConfig() {
    googleOauthConfig = &oauth2.Config{
        RedirectURL:  "http://localhost:5000/api/v1/auth/google/callback",
        ClientID:     viper.GetString("env.GOOGLE_CLIENT_ID"),
        ClientSecret: viper.GetString("env.GOOGLE_CLIENT_SECRET"),
        Scopes:       []string{"https://www.googleapis.com/auth/userinfo.email"},
        Endpoint:     google.Endpoint,
    }
}

func getUserInfo(state string, code string) ([]byte, error) {
    if state != oauthStateString {
        return nil, fmt.Errorf("Invalid oauth state")
    }

    token, err := googleOauthConfig.Exchange(oauth2.NoContext, code)
    if err != nil {
        return nil, fmt.Errorf("Code exchange failed: %s", err.Error())
    }

    res, err := http.Get(oauthGoogleURLAPI + token.AccessToken)
    if err != nil {
        return nil, fmt.Errorf("failed get info: %s", err.Error())
    }

    defer res.Body.Close()
    contents, err := ioutil.ReadAll(res.Body)
    if err != nil {
        return nil, fmt.Errorf("Failed reading response body: %s", err.Error())
    }

    return contents, nil
}

//CONTROLLER

//TestAuth route
func TestAuth(c echo.Context) error {
    return c.String(http.StatusOK, "Test routing auth FROM GOOGLE indonesia!")
}

//GoogleLogin login with google
func GoogleLogin(c echo.Context) error {
    url := googleOauthConfig.AuthCodeURL(oauthStateString)
    return c.Redirect(http.StatusOK, url)
}

//GoogleCallback callback after login with google
func GoogleCallback(c echo.Context) error {
    content, err := getUserInfo(c.FormValue("state"), c.FormValue("code"))
    if err != nil {
        fmt.Println(err.Error())
        return c.Redirect(http.StatusOK, "/")
    }

    return c.String(http.StatusOK, string(content))
}

我得到这样的错误：
