OAuthWebSecurity.VerifyAuthentication authcofig facebook 登录中的错误请求 (400)

Question

我正在从我的网站创建一个社交媒体登录，我已经创建了一个示例项目来检查它，但是 ExternalLoginCallback 操作无法正常工作并且

`   AuthenticationResult result = OAuthWebSecurity.VerifyAuthentication(Url.Action("ExternalLoginCallback", new { ReturnUrl = returnUrl }));`

抛出异常

The remote server returned an error: (400) Bad Request.

堆栈跟踪是

Source Error:

Line 219:        {
Line 220:             AuthenticationResult result = OAuthWebSecurity.VerifyAuthentication(Url.Action("ExternalLoginCallback", new { ReturnUrl = returnUrl }));
Line 221:           // AuthenticationResult result = null;// = OAuthWebSecurity.VerifyAuthentication(Url.Action("ExternalLoginCallback", new { ReturnUrl = returnUrl }));

  OAuthWebSecurity.RegisterFacebookClient(
                appId: ConfigurationManager.AppSettings["FBAPPID"],
                appSecret: ConfigurationManager.AppSettings["FBAPPSECRET"]);

我解决了这个问题。实际问题出在 FB 设置上，我在关闭它开始工作时不小心启用了本机或桌面应用程序选项
