我正在尝试使用galang.org/x/oauth2包编写一个简单的程序.但我似乎无法交换访问令牌的代码.以下错误有点误导,因为它说已经使用了授权代码,但每次调用登录对话框时我都会看到一个新代码.我是Galang的新手,我可能会犯一个基本的错误,任何指针都会非常有用:)

    clientOptions, err = oauth2.New(
        oauth2.Client("xxxxxx", "22222222222222"),
        oauth2.RedirectURL("http://localhost:3000/auth/cb/fb2"),
        oauth2.Scope("public_profile", "email", "user_friends"),
        oauth2.Endpoint(
            "https://www.facebook.com/dialog/oauth",
            "https://graph.facebook.com/oauth/access_token",
        ),
    )

func handleFBSetupOauth(w http.ResponseWriter, r *http.Request) {
    url := clientOptions.AuthCodeURL("state", "online", "auto")
    fmt.Printf("Visit the URL for the auth dialog: %v", url)

    http.Redirect(w, r, url, http.StatusFound)
}

func handleFBOauthCB(w http.ResponseWriter, r *http.Request) (int, string) {
    var err error

    code := r.FormValue("code")
    if code == "" {
        return 500, "No code!"
    }

    fmt.Printf("code - %s", code)

    t, err := clientOptions.NewTransportFromCode(code)
    if err != nil {
        log.Fatal(err)
    } …

我是golang的新手,我正在尝试获得一个软件包,但是我遇到了一个奇怪的错误,似乎无法弄清楚问题是什么？
