facebook - Xamarin.Auth iOS9 身份验证 SSL 错误

Question

我刚刚将 XCode 更新到 7.0 (7A220)，这会将我的模拟器带到 iOS9。

从那一刻起，我无法从模拟器成功执行任何 OAUTH 调用。我尝试了所有模型，从我的应用程序到“示例 Xamarin.Auth 应用程序”。

答案总是一样的:

“认证错误

发生 SSL 错误，无法与服务器建立安全连接"

代码是标准代码，我只更改了我的 AppID。相同的代码适用于同一应用程序的 Android 版本!

var auth = new OAuth2Authenticator (
            clientId: "my app 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);

IOS9模拟器可以上网，所以不是“连通性问题”。我也尝试使用 Facebook SDK，同样的错误。会不会是证书问题？

谢谢

要解决此问题，只需将这些行添加到您的 Info.plist 文件中:

<key>NSAppTransportSecurity</key>
  <dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSExceptionDomains</key>
<dict>
  <key>facebook.com</key>
  <dict>
    <key>NSIncludesSubdomains</key>
    <true/>
    <key>NSExceptionRequiresForwardSecrecy</key>
    <false/>
  </dict>
  <key>fbcdn.net</key>
  <dict>
    <key>NSIncludesSubdomains</key>
    <true/>
    <key>NSExceptionRequiresForwardSecrecy</key>
    <false/>
  </dict>
  <key>akamaihd.net</key>
  <dict>
    <key>NSIncludesSubdomains</key>
    <true/>
    <key>NSExceptionRequiresForwardSecrecy</key>
    <false/>
  </dict>
</dict>

如果您不关心域的额外规则，您可以简单地添加:

 <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict>

注意:您必须清理并重建项目才能看到它使用这些新设置运行!
