Asp.net mvc 如何使用ASP.NET MVC 5和OWIN获取Facebook的名字和姓氏值？
我知道提供了“姓名”字段，但我更愿意显式访问名字和姓氏。有人能帮忙吗？我仍在为ASP.Net MVC绞尽脑汁。在您的Startup.Auth.csAsp.net mvc 如何使用ASP.NET MVC 5和OWIN获取Facebook的名字和姓氏值？,asp.net-mvc,facebook,asp.net-mvc-5,owin,Asp.net Mvc,Facebook,Asp.net Mvc 5,Owin,我知道提供了“姓名”字段，但我更愿意显式访问名字和姓氏。有人能帮忙吗？我仍在为ASP.Net MVC绞尽脑汁。在您的Startup.Auth.csConfigureAuth（IAppBuilder应用程序）方法中，为Facebook设置以下内容： var x = new FacebookAuthenticationOptions(); x.Scope.Add("email"); x.AppId = "*"; x.AppSecret = "**";
ConfigureAuth（IAppBuilder应用程序）var x = new FacebookAuthenticationOptions();
x.Scope.Add("email");
x.AppId = "*";
x.AppSecret = "**";
x.Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = async context =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("FacebookAccessToken", context.AccessToken));
foreach (var claim in context.User)
{
var claimType = string.Format("urn:facebook:{0}", claim.Key);
string claimValue = claim.Value.ToString();
if (!context.Identity.HasClaim(claimType, claimValue))
context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Facebook"));
}
}
};
x.SignInAsAuthenticationType = DefaultAuthenticationTypes.ExternalCookie;
app.UseFacebookAuthentication(x);
/*
app.UseFacebookAuthentication(
appId: "*",
appSecret: "*");
* */
app.UseFacebookAuthentication(new FacebookAuthenticationOptions
{
AuthenticationType = "facebook",
Caption = "Login with Facebook",
SignInAsAuthenticationType = signInAsType,
AppId = ConfigurationManager.AppSettings["FacebookAppId"],
AppSecret = ConfigurationManager.AppSettings["FacebookAppSecret"],
Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = ctx =>
{
foreach (var claim in ctx.User)
{
var claimType = $"urn:facebook:{claim.Key}";
var claimValue = claim.Value.ToString();
if (!ctx.Identity.HasClaim(claim.Key, claimValue))
{
ctx.Identity.AddClaim(new Claim(claim.Key, claimValue));
}
}
return Task.FromResult(0);
}
}
});
var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
var firstNameClaim = loginInfo.ExternalIdentity.Claims.First(c => c.Type == "urn:facebook:first_name");
在facebook选项范围中添加名字和姓氏
var facebookOptions = new Microsoft.Owin.Security.Facebook.FacebookAuthenticationOptions()
{
AppId = "your app id",
AppSecret = "your app secret",
};
facebookOptions.Scope.Add("email");
facebookOptions.Scope.Add("first_name");
facebookOptions.Scope.Add("last_name");
return facebookOptions;
Facebook更改了其权限api。您可以在此处获得更多信息： 名称需要公共配置文件权限
var facebookAuthenticationOptions = new FacebookAuthenticationOptions()
{
AppId = "appId",
AppSecret = "key"
};
facebookAuthenticationOptions.Scope.Add("email");
facebookAuthenticationOptions.Scope.Add("public_profile");
app.UseFacebookAuthentication(facebookAuthenticationOptions);
var loginInfo = await authenticationManager.GetExternalLoginInfoAsync();
loginInfo.ExternalIdentity.Claims.First(c => c.Type == "urn:facebook:name")
HttpContext.GetOwinContext().Authentication;
不幸的是，由于Facebook使用API update 2.4更改了默认返回值，这种方法不再有效 现在看来，获得第一个_名称等的唯一方法是使用Facebook Graph API（） 我还在Katana项目网站上找到了解决这个问题的方法，并且已经提交了一个请求，但是还没有被合并
希望这能为某人节省一点时间；） 截至2017年，这是我的工作代码（感谢上面David Poxon的代码）。确保您已升级到Microsoft.Owin.Security.Facebook的3.1.0版 在Startup.Auth.cs（或在某些情况下为Startup.cs）中，放置以下代码：
app.UseFacebookAuthentication(new FacebookAuthenticationOptions()
{
AppId = "***",
AppSecret = "****",
BackchannelHttpHandler = new HttpClientHandler(),
UserInformationEndpoint = "https://graph.facebook.com/v2.8/me?fields=id,name,email,first_name,last_name",
Scope = { "email" },
Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = async context =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("FacebookAccessToken", context.AccessToken));
foreach (var claim in context.User)
{
var claimType = string.Format("urn:facebook:{0}", claim.Key);
string claimValue = claim.Value.ToString();
if (!context.Identity.HasClaim(claimType, claimValue))
context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Facebook"));
}
}
}
});
var firstName = loginInfo.ExternalIdentity.Claims.First(c => c.Type == "urn:facebook:first_name").Value;
app.UseFacebookAuthentication(new FacebookAuthenticationOptions()
{
AppId = "***",
AppSecret = "****",
BackchannelHttpHandler = new HttpClientHandler(),
UserInformationEndpoint = "https://graph.facebook.com/v2.8/me?fields=id,name,email,first_name,last_name",
Scope = { "email" },
Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = async context =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("FacebookAccessToken", context.AccessToken));
foreach (var claim in context.User)
{
var claimType = string.Format("urn:facebook:{0}", claim.Key);
string claimValue = claim.Value.ToString();
if (!context.Identity.HasClaim(claimType, claimValue))
context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Facebook"));
}
}
}
});
var firstName = loginInfo.ExternalIdentity.Claims.First(c => c.Type == "urn:facebook:first_name").Value;
同样，要获取姓氏，请使用上面的一行，并将
urn:facebook:first\u nameurn:facebook:last\u namefacebook已更改其Graph API在升级2.4中返回值的方式。现在，您需要显式指定要返回的所有字段
请参见以下注释：
Graph API在2.4版中的变化
在过去，来自Graph API调用的响应返回一组默认字段。为了减少有效负载大小并改善移动设备上的延迟
我们已经减少了为其返回的默认字段的数量
大多数图形API调用。在v2.4中，您需要声明性地列出
呼叫的响应字段
从facebook获取电子邮件、名字和姓氏：
首先，您需要安装nuget软件包
然后，在startup.Auth.cs中，更改Facebook身份验证的配置，如下所示：
app.UseFacebookAuthentication(new FacebookAuthenticationOptions
{
// put your AppId and AppSecret here. I am reading them from AppSettings
AppId = ConfigurationManager.AppSettings["FacebookAppId"],
AppSecret = ConfigurationManager.AppSettings["FacebookAppSecret"],
Scope = { "email" },
Provider = new FacebookAuthenticationProvider
{
OnAuthenticated = context =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("FacebookAccessToken", context.AccessToken));
return Task.FromResult(true);
}
}
});
// this is no longer needed
//app.UseFacebookAuthentication(
// appId: ConfigurationManager.AppSettings["FacebookAppId"],
// appSecret: ConfigurationManager.AppSettings["FacebookAppSecret"]);
最后，在AccountController中，将以下代码添加到
ExternalLoginCallback方法：
if (string.Equals(loginInfo.Login.LoginProvider, "facebook", StringComparison.CurrentCultureIgnoreCase))
{
var identity = AuthenticationManager.GetExternalIdentity(DefaultAuthenticationTypes.ExternalCookie);
var access_token = identity.FindFirstValue("FacebookAccessToken");
var fb = new FacebookClient(access_token);
// you need to specify all the fields that you want to get back
dynamic myInfo = fb.Get("/me?fields=email,first_name,last_name");
string email = myInfo.email;
string firstName = myInfo.first_name;
string lastName = myInfo.last_name;
}
请参阅以获取更多您可以获取的参数。从2019年1月起，我想确认如何执行此操作，并提供一些额外的位（根据答案的编写年份，存在许多相互冲突的信息！）。David和Waqas有最好的答案（IMO）。我使用的是MVC5、AsNetIdentity 2和IdentityServer 3
首先，您的Facebook身份提供商配置：
var x = new FacebookAuthenticationOptions();
x.Scope.Add("email");
x.AppId = "*";
x.AppSecret = "**";
x.Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = async context =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("FacebookAccessToken", context.AccessToken));
foreach (var claim in context.User)
{
var claimType = string.Format("urn:facebook:{0}", claim.Key);
string claimValue = claim.Value.ToString();
if (!context.Identity.HasClaim(claimType, claimValue))
context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Facebook"));
}
}
};
x.SignInAsAuthenticationType = DefaultAuthenticationTypes.ExternalCookie;
app.UseFacebookAuthentication(x);
/*
app.UseFacebookAuthentication(
appId: "*",
appSecret: "*");
* */
app.UseFacebookAuthentication(new FacebookAuthenticationOptions
{
AuthenticationType = "facebook",
Caption = "Login with Facebook",
SignInAsAuthenticationType = signInAsType,
AppId = ConfigurationManager.AppSettings["FacebookAppId"],
AppSecret = ConfigurationManager.AppSettings["FacebookAppSecret"],
Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = ctx =>
{
foreach (var claim in ctx.User)
{
var claimType = $"urn:facebook:{claim.Key}";
var claimValue = claim.Value.ToString();
if (!ctx.Identity.HasClaim(claim.Key, claimValue))
{
ctx.Identity.AddClaim(new Claim(claim.Key, claimValue));
}
}
return Task.FromResult(0);
}
}
});
与其他一些答案不同，这将额外请求的字段与默认情况下获得的字段相结合，并将urn:facebook:
从声明的前面去掉，以便与默认声明命名方案匹配
您不需要添加任何额外的范围
或字段
（至少，不需要添加姓名）。Microsoft.Owin.Security.Facebook
的4.1版已经为您实现了这一点。这个相关位：
public FacebookAuthenticationOptions()
: base(Constants.DefaultAuthenticationType)
{
Caption = Constants.DefaultAuthenticationType;
CallbackPath = new PathString("/signin-facebook");
AuthenticationMode = AuthenticationMode.Passive;
Scope = new List<string>();
BackchannelTimeout = TimeSpan.FromSeconds(60);
SendAppSecretProof = true;
_fields = new HashSet<string>();
CookieManager = new CookieManager();
AuthorizationEndpoint = Constants.AuthorizationEndpoint;
TokenEndpoint = Constants.TokenEndpoint;
UserInformationEndpoint = Constants.UserInformationEndpoint;
Scope.Add("public_profile");
Scope.Add("email");
Fields.Add("name");
Fields.Add("email");
Fields.Add("first_name");
Fields.Add("last_name");
}
希望这对别人有帮助 对于VB.NET开发人员，这是Startup.Auth.VB中的代码
Dim fb = New FacebookAuthenticationOptions()
fb.Scope.Add("email")
fb.AppId = "*"
fb.AppSecret = "*"
fb.Provider = New FacebookAuthenticationProvider() With
{
.OnAuthenticated = Async Function(context)
context.Identity.AddClaim(New System.Security.Claims.Claim("FacebookAccessToken", context.AccessToken))
For Each claim In context.User
Dim claimType = String.Format("urn:facebook:{0}", claim.Key)
Dim claimValue As String = claim.Value.ToString()
If Not context.Identity.HasClaim(claimType, claimValue) Then context.Identity.AddClaim(New System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Facebook"))
Next
End Function
}
fb.SignInAsAuthenticationType = DefaultAuthenticationTypes.ExternalCookie
app.UseFacebookAuthentication(fb)
名字和姓氏不是有效的作用域。您好，登录信息来自哪里？我们应该把这行代码放在哪里？嗨，我编辑了答案，如果还有什么遗漏，请告诉我。当心！这对我有用；我可以得到名字+姓氏。但是电子邮件总是null
。另外，你知道一种分别获取名字和姓氏的方法吗？对我来说，name、first_name和last_name是null
。对我来说是有效的-然后还有一项从提供者不可知的值中获取值的工作，我目前正在做类似于公共字符串FirstName{get{return chainValue（"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname“，//谷歌”urn:facebook:first_name”//facebook）；}}
