【问题描述】：
好的，所以我尝试使用 Xamarin.Auth 在 Xamarin.iOS 上进行非常基本的身份验证，但出现错误：“应用程序配置不允许给定 URL。：一个或多个给定 URL 不可用应用程序的设置允许。它必须与网站 URL 或画布 URL 匹配，或者域必须是应用程序域之一的子域。"
我已经在谷歌上搜索了一段时间，看来您可能无法再将 Xam.Auth 用于 Facebook —— 这似乎不太可能......
这是我的示例代码（没有我的 FB 应用程序 ID）——您会注意到它实际上是 Xam 示例代码的副本：
using System;
using System.Collections.Generic;
using System.Json;
using System.Linq;
using System.Threading.Tasks;
using MonoTouch.Dialog;
#if __UNIFIED__
using Foundation;
using UIKit;
#else
using MonoTouch.Foundation;
using MonoTouch.UIKit;
#endif
namespace Xamarin.Auth.Sample.iOS
{
[Register ("AppDelegate")]
public partial class AppDelegate : UIApplicationDelegate
{
void LoginToFacebook (bool allowCancel)
{
var auth = new OAuth2Authenticator (
clientId: "SOME_ID",
scope: "",
authorizeUrl: new Uri ("https://m.facebook.com/dialog/oauth/"),
redirectUrl: new Uri ("http://www.facebook.com/connect/login_success.html"));
auth.AllowCancel = allowCancel;
// If authorization succeeds or is canceled, .Completed will be fired.
auth.Completed += (s, e) =>
{
// We presented the UI, so it's up to us to dismiss it.
dialog.DismissViewController (true, null);
if (!e.IsAuthenticated) {
facebookStatus.Caption = "Not authorized";
dialog.ReloadData();
return;
}
// Now that we're logged in, make a OAuth2 request to get the user's info.
var request = new OAuth2Request("GET", new Uri ("https://graph.facebook.com/me"), null, e.Account);
request.GetResponseAsync().ContinueWith (t => {
if (t.IsFaulted)
facebookStatus.Caption = "Error: " + t.Exception.InnerException.Message;
else if (t.IsCanceled)
facebookStatus.Caption = "Canceled";
else
{
var obj = JsonValue.Parse(t.Result.GetResponseText());
facebookStatus.Caption = "Logged in as " + obj["name"];
}
dialog.ReloadData();
}, uiScheduler);
};
UIViewController vc = auth.GetUI ();
dialog.PresentViewController (vc, true, null);
}
public override bool FinishedLaunching (UIApplication app, NSDictionary options)
{
facebook = new Section ("Facebook");
facebook.Add (new StyledStringElement("Log in", () => LoginToFacebook (true)));
facebook.Add (new StyledStringElement("Log in (no cancel)", () => LoginToFacebook (false)));
facebook.Add (facebookStatus = new StringElement (String.Empty));
dialog = new DialogViewController (new RootElement ("Xamarin.Auth Sample") {
facebook,
});
window = new UIWindow (UIScreen.MainScreen.Bounds);
window.RootViewController = new UINavigationController (dialog);
window.MakeKeyAndVisible ();
return true;
}
private readonly TaskScheduler uiScheduler =
TaskScheduler.FromCurrentSynchronizationContext();
UIWindow window;
DialogViewController dialog;
Section facebook;
StringElement facebookStatus;
// This is the main entry point of the application.
static void Main (string[] args)
{
UIApplication.Main (args, null, "AppDelegate");
}
}
}
【问题讨论】：
-
您是否已将 URL
"http://www.facebook.com/connect/login_success.html"作为有效的重定向 URL 添加到您在 Facebook 上的应用配置？我希望您拥有域中的 URL，这看起来像您从示例中复制的内容。 -
你是个天才，我觉得有点傻。这就是我这周熬夜太多的原因。谢谢克里斯！如果您愿意，请将您的回复作为答案，我很乐意接受。
