将 Void 函数分配给 Auth 事件时出现编译错误

Question

我正在构建一个需要 Spotify 使用 ImplicitGrantAuth 对用户进行身份验证的应用程序。我已经在 Spotify 的 dev 上设置了我的应用程序并且有一个 ClientID。我正在为此应用程序使用 JohnnyCrazy/SpotifyAPI-NET。

API 可以找到隐式授权授权的文档 here.
可以找到 Spotify 的隐式授权流程文档 here.
原来的class for ImplicitGrantAuth可以找到 here.

代码片段：

static ImplicitGrantAuth auth;
static void Main(string[] args)
{
    //Create the auth object
    auth = new ImplicitGrantAuth()
    {
        //Your client Id
        ClientId = "XXXXXXXXXXXXXXXXXX", // example only
        //Set this to localhost if you want to use the built-in HTTP Server
        RedirectUri = "http://localhost",
        //How many permissions we need?
        Scope = Scope.UserReadPrivate,
    };
    //Start the internal http server
    auth.StartHttpServer();
    //When we got our response
    auth.OnResponseReceivedEvent += auth_OnResponseReceivedEvent; // <-- Error here!
    //Start
    auth.DoAuth();
}

static void auth_OnResponseReceivedEvent(Token token, string state, string error)
{
    //stop the http server
    auth.StopHttpServer();

    var spotify = new SpotifyWebAPI()
    {
        TokenType = token.TokenType,
        AccessToken = token.AccessToken
    };
    //We can now make calls with the token object
}

编译错误：

No overload for 'auth_OnResponseReceivedEvent' matches delegate 'SpotifyAPI.Web.Auth.ImplicitGrantAuth.OnResponseReceived'

我不确定我是否忽略了一些非常简单的东西，或者我是否需要特别添加一些东西。我对使用事件处理程序也很陌生。

您的 auth_OnResponseReceivedEvent 方法中的参数过多。 OnResponseReceived委托中没有string state参数：

public delegate void OnResponseReceived(Token token, String error);

public event OnResponseReceived OnResponseReceivedEvent;
