Google OAuth Войти Проблемы в MVC 4 Применение

Question

я столкнулся такая же проблема, как упоминалось в AuthenticationResult.IsSuccessful started returning false for google

Я использую MVC 4 Web Api приложение и переходить на MVC 5 будет большое изменение. Кто-то другой сталкивается с той же проблемой?

Есть ли образцы для использования DotnetOpenAuth.OAuth2, чтобы я мог пропустить переход к DotnetOpenAuth.GoogleOAuth2 в приложении MVC 5.

Answer 1

В случае, если кто-то все-таки нужно использовать Google OpenID Connect в MVC 4 вот код:

В AuthConfig.cs пишут:

OAuthWebSecurity.RegisterClient(new GoogleCustomClient("YoutGoogleAPIKey", "GoogleSecret"), "Google", null); 

и класс GoogleCustomClient (основано на примере LinkedIn OAuth Я нашел):

using DotNetOpenAuth.AspNet; 
using DotNetOpenAuth.AspNet.Clients; 
using DotNetOpenAuth.OAuth; 
using System; 
using System.Collections.Generic; 
using System.IO; 
using System.Net; 
using System.Text; 
using System.Text.RegularExpressions; 
using System.Web; 
using System.Web.Script.Serialization; 


namespace MyProject.CustomProviders 
{ 
public class GoogleCustomClient : OAuth2Client 
{ 
    #region Constants and Fields 
    private const string AuthorizationEndpoint = "https://accounts.google.com/o/oauth2/auth"; 
    private const string TokenEndpoint = "https://accounts.google.com/o/oauth2/token"; 
    private readonly string _clientId; 
    private readonly string _clientSecret; 
    private string absoluteReturnUrl = string.Empty; 
    #endregion 

    public GoogleCustomClient(string clientId, string clientSecret) : base("Google") 
    { 
     this._clientId = clientId; 
     this._clientSecret = clientSecret; 
    } 

    protected override Uri GetServiceLoginUrl(Uri returnUrl) 
    { 
     StringBuilder serviceUrl = new StringBuilder(); 
     serviceUrl.AppendFormat("{0}?", AuthorizationEndpoint); 
     serviceUrl.Append("response_type=code"); 
     serviceUrl.AppendFormat("&client_id={0}", this._clientId); 
     serviceUrl.Append("&scope=email"); 
     absoluteReturnUrl = Regex.Match(returnUrl.ToString(), "https://(\\d|\\w|\\/|:|\\.){1,}").Value; 
     serviceUrl.AppendFormat("&redirect_uri={0}", Uri.EscapeDataString(absoluteReturnUrl)); 
     serviceUrl.AppendFormat("&state={0}", Regex.Match(returnUrl.AbsoluteUri, "(?<=__sid__=).*?($|&)", RegexOptions.IgnoreCase).Value); 
     return new Uri(serviceUrl.ToString()); 
    } 

    protected override IDictionary<string, string> GetUserData(string accessToken) 
    { 
     var request = WebRequest.Create("https://www.googleapis.com/oauth2/v1/userinfo?access_token=" + Uri.EscapeDataString(accessToken)); 

     string responseText = string.Empty; 
     using (var response = request.GetResponse()) 
     { 
      using (var responseStream = response.GetResponseStream()) 
      { 
       using (var reader = new StreamReader(responseStream, Encoding.UTF8)) 
       { 
        responseText = reader.ReadToEnd(); 
       } 
      } 
     } 
     Dictionary<string, string> userData = new Dictionary<string, string>(); 
     JavaScriptSerializer deserializer = new JavaScriptSerializer(); 
     Dictionary<string, string> responseData = deserializer.Deserialize<Dictionary<string, string>>(responseText); 
     userData.Add("id", responseData["id"]); 
     userData.Add("firstname", responseData["given_name"]); 
     userData.Add("lastname", responseData["family_name"]); 
     userData.Add("emailAddress", responseData["email"]); 
     userData.Add("picture", responseData["picture"]); 
     userData.Add("accesstoken", ""); 
     userData.Add("allData", responseText); 
     return userData; 
    } 

    protected override string QueryAccessToken(Uri returnUrl, string authorizationCode) 
    { 
     StringBuilder postData = new StringBuilder(); 
     postData.Append("grant_type=authorization_code"); 
     postData.AppendFormat("&code={0}", authorizationCode); 
     postData.AppendFormat("&redirect_uri={0}", absoluteReturnUrl.EndsWith(returnUrl.ToString(), StringComparison.OrdinalIgnoreCase) ? HttpUtility.UrlEncode(absoluteReturnUrl) : ""); 
     postData.AppendFormat("&client_id={0}", this._clientId); 
     postData.AppendFormat("&client_secret={0}", this._clientSecret); 

     string response = ""; 
     string accessToken = ""; 

     var webRequest = (HttpWebRequest)WebRequest.Create(TokenEndpoint); 

     webRequest.Method = "POST"; 
     webRequest.ContentType = "application/x-www-form-urlencoded"; 

     try 
     { 
      using (Stream s = webRequest.GetRequestStream()) 
      { 
       using (StreamWriter sw = new StreamWriter(s)) 
        sw.Write(postData.ToString()); 
      } 
      using (WebResponse webResponse = webRequest.GetResponse()) 
      { 
       using (StreamReader reader = new StreamReader(webResponse.GetResponseStream())) 
       { 
        response = reader.ReadToEnd(); 
       } 
      } 

      JavaScriptSerializer deserializer = new JavaScriptSerializer(); 
      var userData = deserializer.Deserialize<Dictionary<string, string>>(response); 
      accessToken = (string)userData["access_token"]; 
     } 
     catch (Exception) 
     { 
      return null; 
     } 

     return accessToken; 

    } 

    public override AuthenticationResult VerifyAuthentication(HttpContextBase context, Uri returnPageUrl) 
    { 

     string code = context.Request.QueryString["code"]; 
     if (string.IsNullOrEmpty(code)) 
     { 
      return AuthenticationResult.Failed; 
     } 

     string accessToken = this.QueryAccessToken(returnPageUrl, code); 
     if (accessToken == null) 
     { 
      return AuthenticationResult.Failed; 
     } 

     IDictionary<string, string> userData = this.GetUserData(accessToken); 
     if (userData == null) 
     { 
      return AuthenticationResult.Failed; 
     } 

     string email = userData["emailAddress"]; 
     string id = userData["id"]; 

     userData["accesstoken"] = accessToken; 

     return new AuthenticationResult(isSuccessful: true, provider: this.ProviderName, providerUserId: id, userName: email, extraData: userData); 
    } 
} 
} 

И по какой-то причине OAuthWebSecurity.VerifyAuthentication в функции «ExternalLoginCallback» не собирается в правый класс, так вот это работа вокруг:

AuthenticationResult result = ((GoogleCustomClient)OAuthWebSecurity.GetOAuthClientData("google").AuthenticationClient).VerifyAuthentication(this.HttpContext, uri);
