使用OpenOAuthProvider
我在Visual Studio中创建了默认的ASP.NET项目模板，然后转到AuthConfig里面的App_Start文件夹。然后我取消注释以下行：
OpenAuth.AuthenticationClients.AddGoogle();
我按下了Google登录按钮：
当我点击Google按钮时，我收到此错误：
An exception of type 'DotNetOpenAuth.Messaging.ProtocolException'
occurred in DotNetOpenAuth.OpenId.RelyingParty.dll but was not handled in user code
Additional information: No OpenID endpoint found.

实际上这种实现（OpenId）是deprecated。如果可能，您应该更改为MVC5。在MVC5中，它非常straightforward。该解决方案仍然有效。如果您不能，则需要撰写此yourself或使用使用OAuth2与Google通信的第三方组件。有关已弃用功能的详细信息，请参阅this answer。

正如您在使用Web Form Application的聊天评论中提到的那样。点击Google的事件。
protected void lnkbtngplus_Click(object sender, EventArgs e)
{
try
{
var Googleurl = "https://accounts.google.com/o/oauth2/auth?response_type=code&redirect_uri=" + ConfigurationManager.AppSettings["googleplus_redirect_url"] + "&scope=googleapis.com/auth/…" + ConfigurationManager.AppSettings["googleplus_client_id"];
Session["loginWith"] = "google";
Response.Redirect(Googleurl);
}
catch (Exception ex)
{
Master.Messages(ex.Message);
}
}
在重定向网址上，您可以收集参数值，如下所示
try
{
var url = Request.Url.Query;
if (url != "")
{
string queryString = url.ToString();
char[] delimiterChars = { '=' };
string[] words = queryString.Split(delimiterChars);
string code = words[1];
SocialNetwork.GoogleUserOutputData json_data = SocialNetwork.Googlemethod(code);
String email = String.Empty;
String id = String.Empty;
email = json_data.email;
id = json_data.given_name;
if (email != null && email != "")
{
txtFname.Text = id;
txtemail.Text = email;
}
}
}
catch (Exception ex)
{
}
在 SocialNetwork类文件中，我有以下方法
#region Google
protected static string Parameters;
public static GoogleUserOutputData Googlemethod(string code)
{
GoogleUserOutputData serStatus1 = new GoogleUserOutputData();
string json_data = string.Empty;
if (code != null)
{
//get the access token
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("https://accounts.google.com/o/oauth2/token");
webRequest.Method = "POST";
Parameters = "code=" + code + "&client_id=" + googleplus_client_id + "&client_secret=" + googleplus_client_sceret + "&redirect_uri=" + googleplus_redirect_url + "&grant_type=authorization_code";
byte[] byteArray = Encoding.UTF8.GetBytes(Parameters);
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = byteArray.Length;
Stream postStream = webRequest.GetRequestStream();
// Add the post data to the web request
postStream.Write(byteArray, 0, byteArray.Length);
postStream.Close();
WebResponse response = webRequest.GetResponse();
postStream = response.GetResponseStream();
StreamReader reader = new StreamReader(postStream);
string responseFromServer = reader.ReadToEnd();
GooglePlusAccessToken serStatus = JsonConvert.DeserializeObject<GooglePlusAccessToken>(responseFromServer);//JsonConvert.DeserializeObject<GooglePlusAccessToken>(responseFromServer);
//GooglePlusAccessToken serStatus = new GooglePlusAccessToken();
if (serStatus != null)
{
string accessToken = string.Empty;
accessToken = serStatus.access_token;
if (!string.IsNullOrEmpty(accessToken))
{
using (var w = new WebClient())
{
json_data = w.DownloadString("https://www.googleapis.com/oauth2/v1/userinfo?access_token=" + accessToken);
serStatus1 = JsonConvert.DeserializeObject<GoogleUserOutputData>(json_data);
}
}
else
{ }
}
else
{ }
}
return serStatus1;
}
public class GoogleUserOutputData
{
public string id { get; set; }
public string name { get; set; }
public string given_name { get; set; }
public string email { get; set; }
public string picture { get; set; }
}
public class GooglePlusAccessToken
{
public string access_token { get; set; }
public string token_type { get; set; }
public int expires_in { get; set; }
public string id_token { get; set; }
public string refresh_token { get; set; }

您可能会通过添加以下代码来遗漏ConfigureAuth for Google身份验证：
app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
{
ClientId = "*****************.googleusercontent.com",
ClientSecret = "********************"
});
On Startup.Auth.cs
public void ConfigureAuth(IAppBuilder app)
{
// Configure the db context, user manager and signin manager to use a single instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider
// Configure the sign in cookie
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Account/Login"),
Provider = new CookieAuthenticationProvider
{
// Enables the application to validate the security stamp when the user logs in.
// This is a security feature which is used when you change a password or add an external login to your account.
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
validateInterval: TimeSpan.FromMinutes(30),
regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
}
});
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
// Enables the application to temporarily store user information when they are verifying the second factor in the two-factor authentication process.
app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));
// Enables the application to remember the second login verification factor such as phone or email.
// Once you check this option, your second step of verification during the login process will be remembered on the device where you logged in from.
// This is similar to the RememberMe option when you log in.
app.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);
// Uncomment the following lines to enable logging in with third party login providers
//app.UseMicrosoftAccountAuthentication(
// clientId: "",
// clientSecret: "");
//app.UseTwitterAuthentication(
// consumerKey: "",
// consumerSecret: "");
//app.UseFacebookAuthentication(
// appId: "",
// appSecret: "");
// The same with Facebook, Twitter, MicrosoftAccount
app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
{
ClientId = "*****************.googleusercontent.com",
ClientSecret = "********************"
});
