使用SimpleMembership,您可以向外部身份验证提供程序按钮添加一个图标,如下所示:
SimpleMembership:
Dictionary<string, object> FacebooksocialData = new Dictionary<string, object>();
FacebooksocialData.Add("Icon", "/content/images/gui/loginFacebook.png");
OAuthWebSecurity.RegisterFacebookClient(
appId: "x",
appSecret: "x",
displayName: "Facebook",
extraData: FacebooksocialData);
然后在您的视图中显示如下:
@foreach (AuthenticationClientData p in Model)
{
<button class="externalLoginService" style="cursor:pointer;color:transparent;border:none;background:url(@p.ExtraData["Icon"]);width:94px;height:93px;margin-right:20px;" type="submit" name="provider" value="@p.AuthenticationClient.ProviderName" title="Log in with @p.DisplayName">@p.DisplayName</button>
}
ASP.NET标识(?):
app.UseFacebookAuthentication(
appId: "x",
appSecret: "x");
如何使用ASP.NET Identity(控制器和视图)实现相同的功能?

另一种方法:
采取了这个博客中的一些内容(使用zocial图标,但我发现那些是过度的 - 请参阅css文件,你会知道我的意思): http://www.beabigrockstar.com/pretty-social-login-buttons-for-asp-net-mvc-5/
并且这样做了:
Startup.Auth.cs
(没有额外的东西,只是MVC 5应用程序的标准默认内容)
app.UseFacebookAuthentication(appId: "x", appSecret: "x");
app.UseGoogleAuthentication();
CSS:
.socialLoginButton {
cursor:pointer;color:transparent;border:none;width:94px;height:93px;margin-right:20px;
}
.socialLoginButton.facebook {
background:url(/content/images/gui/loginFacebook.png);
}
.socialLoginButton.google {
background:url(/content/images/gui/loginGoogle.png);
}
查看:
<button type="submit" class="externalLoginService socialLoginButton @p.AuthenticationType.ToLower()" id="@p.AuthenticationType" name="provider" value="@p.AuthenticationType" title="Log in with @p.Caption">@p.AuthenticationType</button>
在上面的其他解决方案/答案中使用类而不是不那么优雅的样式属性。

您仍然可以执行类似的操作,基本上在Startup.Auth.cs中,您需要在启用身份验证提供程序时向AuthenticationDescription添加额外数据:
var desc = new AuthenticationDescription();
desc.Caption = "Google";
desc.AuthenticationType = "Google";
desc.Properties["Img"] = "<img>";
app.UseGoogleAuthentication(new GoogleAuthenticationOptions() { Description = desc });
然后在你的按钮中使用@ p.Properties [“Img”],就像你在_ExternalLoginListPartial视图中所做的那样
<legend>Use another service to log in.</legend>
<p>
@foreach (AuthenticationDescription p in loginProviders) {
<button type="submit" class="btn" id="@p.AuthenticationType" name="provider" value="@p.AuthenticationType" title="Log in using your @p.Caption account">@p.AuthenticationType</button>
}
</p>
