OwinのOAuthプロバイダーTwitterやマイクロソフト

Question

私はTwitterやマイクロソフトのためにnullを返す下の行に問題が生じています：

var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync(); 

これは以下のようにアカウントのコントローラである：スタートアップで

[AllowAnonymous] 
public async Task<ActionResult> ExternalLoginCallback(string returnUrl) 
{ 
    var loginInfo = await 
    AuthenticationManager.GetExternalLoginInfoAsync(); 

    if (loginInfo == null) 
    { 
     return RedirectToAction("Login"); 
    } 

    var result = await SignInManager.ExternalSignInAsync(loginInfo, false); 
    switch (result) 
    { 
     case SignInStatus.Success: 
      return RedirectToLocal(returnUrl); 
     case SignInStatus.LockedOut: 
      return View("Lockout"); 
     //case SignInStatus.RequiresVerification: 
     // return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = false }); 
     case SignInStatus.Failure: 
     default: 
      // If the user does not have an account, then prompt the user to create an account 
      ViewBag.ReturnUrl = returnUrl; 
      ViewBag.LoginProvider = loginInfo.Login.LoginProvider; 
      return View("ExternalLoginConfirmation", new AccountExternalLoginConfirmationViewModel { Email = loginInfo.Email }); 
    } 
} 

.auth.cs現在の設定は次のとおりです。

app.UseTwitterAuthentication(
    new TwitterAuthenticationOptions() 
    { 
     ConsumerKey = ConfigurationManager.AppSettings["TwitterAPIKey"], 
     ConsumerSecret = ConfigurationManager.AppSettings["TwitterAPISecret"], 

     Provider = new TwitterAuthenticationProvider() 
     { 
      OnAuthenticated = context => 
      { 
       context.Identity.AddClaim(new Claim("urn:tokens:twitter:accesstoken", context.AccessToken)); 
       context.Identity.AddClaim(new Claim("urn:tokens:twitter:accesstokensecret", 
        context.AccessTokenSecret)); 
       return Task.FromResult(true); 
      } 
     } 
    }); 

     app.UseMicrosoftAccountAuthentication(new MicrosoftAccountAuthenticationOptions() 
     { 
      ClientId = ConfigurationManager.AppSettings["MicrosoftAPIKey"], 
      ClientSecret = ConfigurationManager.AppSettings["MicrosoftAPISecret"], 
      // Scope = { "wl.basic", "wl.emails" }, 
      Provider = new MicrosoftAccountAuthenticationProvider() 
      { 
       OnAuthenticated = context => 
       { 
        context.Identity.AddClaim(new Claim("urn:microsoftaccount:access_token", context.AccessToken, "Microsoft")); 
        context.Identity.AddClaim(new Claim("urn:microsoft:email", context.Email)); 
        return Task.FromResult(true); 
       } 
      } 
     }); 

Scope = { "wl.basic"、 "wl.emails"}をMicrosoftAccountAuthenticationOptionsに追加します。しかし、これは悪い要求を返します。 twitterとmicrosoft loginでこの問題を解決する方法に関するアイデア。私はマイクロソフトのために使用しています

私のURLが リダイレクトURLです：https://localhost/signin-microsoft ログアウトURL：https://localhost/account/logout ホームページ：https://localhost

Twitterの ウェブサイト：https://127.0.0.1 コールバックURL：https://127.0.0.1/signin-twitter

私はライブで試してみましたまたライブにURLがあり、まだヌルになっています var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync（）;

これを試してみてください：

 

    var options = new TwitterAuthenticationOptions 
     { 
      SignInAsAuthenticationType = signInAsType, 
      ConsumerKey = "...", 
      ConsumerSecret = "...", 
      Provider = new TwitterAuthenticationProvider() 
      { 

       OnAuthenticated = async ctx => 
       { 


var manager = new OAuth.Manager(
         "-your-twitter-access-token-", 
         "-your-twitter-access-token-secret-", 
         ctx.AccessToken, 
         ctx.AccessTokenSecret); 
        var url = "https://api.twitter.com/1.1/account/verify_credentials.json"; 
        var authzHeader = manager.GenerateAuthzHeader(url, "GET"); 
        var request = (HttpWebRequest)WebRequest.Create(url); 
        request.Method = "GET"; 
        request.PreAuthenticate = true; 
        request.AllowWriteStreamBuffering = true; 
        request.Headers.Add("Authorization", authzHeader); 
        using (var response = (HttpWebResponse)request.GetResponse()) 
        { 
         if (response.StatusCode != HttpStatusCode.OK) 
          throw new Exception("NOK"); 
         var responseStream = response.GetResponseStream(); 

         var reader = new System.IO.StreamReader(responseStream); 
         var res = reader.ReadToEnd(); 
         Newtonsoft.Json.Linq.JObject data = (Newtonsoft.Json.Linq.JObject)JsonConvert.DeserializeObject(res); 

         var claims = new List<Claim>(); 

         claims.Add(new Claim(Core.Constants.ClaimTypes.RawData, ctx.Identity.Claims.ToJsonString())); 
         claims.Add(new Claim(Core.Constants.ClaimTypes.AccessToken, ctx.AccessToken)); 
         claims.Add(new Claim(Core.Constants.ClaimTypes.AccessTokenSecret, ctx.AccessTokenSecret)); 
         claims.Add(new Claim(Core.Constants.ClaimTypes.Subject, ctx.UserId)); 
         claims.Add(new Claim(Core.Constants.ClaimTypes.Name, data["name"].TokenString())); 
         claims.Add(new Claim(Core.Constants.ClaimTypes.Locale, GenerateLocale(data["lang"].TokenString()))); 
         claims.Add(new Claim(Core.Constants.ClaimTypes.ZoneInfo, GenerateZone(data["location"].TokenString(), data["time_zone"].TokenString()))); 
         claims.Add(new Claim(Core.Constants.ClaimTypes.WebSite, data["url"].TokenString())); 
         claims.Add(new Claim(Core.Constants.ClaimTypes.ProfileUrl, "https://twitter.com/" + ctx.ScreenName)); 
         claims.Add(new Claim(Core.Constants.ClaimTypes.Picture, data["profile_image_url"].TokenString())); 

         await PrepClaims(ctx.Identity, claims); 

        } 
       } 
      }
