我在开源项目中调试OWIN软件包升级时遇到了困难。简短的描述是,当我从v2.1升级时,使用外部登录会在新的v3版本中中断,并且在调试过程中我无法弄清有什么不同。请记住,我的代码没有任何变化,我只更新了OWIN组件(Microsoft.Owin和其他子命名空间中的包)。
它从以下表单开始:
<form action="/Forums/Authorization/ExternalLogin?ReturnUrl=http%3A%2F%2Flocalhost%3A1973%2FForums" method="post"><input name="__RequestVerificationToken" type="hidden" value="--verificationtoken--" /> <h2>External Logins</h2>
<p>
<button type="submit" id="Google" name="provider" value="Google" class="btn btn-primary">Google</button>
</p>
</form>
它发布到此方法:
https://github.com/POPWorldMedia/POPForums/blob/v13.0.0/PopForums/Controllers/AuthorizationController.cs
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult ExternalLogin(string provider, string returnUrl)
{
return new ChallengeResult(provider, Url.Action("ExternalLoginCallback", "Authorization", new { loginProvider = provider, ReturnUrl = returnUrl, area = "PopForums" }));
}
回调将在此处到达:
public async Task<ActionResult> ExternalLoginCallback(string loginProvider, string returnUrl)
{
var authentication = _owinContext.Authentication;
var authResult = await _externalAuthentication.GetAuthenticationResult(authentication);
if (authResult == null)
return RedirectToAction("Login", "Account", new { error = Resources.ExpiredLogin });
...
第二行称为:
https://github.com/POPWorldMedia/POPForums/blob/v13.0.0/PopForums/ExternalLogin/ExternalAuthentication.cs
public async Task<ExternalAuthenticationResult> GetAuthenticationResult(IAuthenticationManager authenticationManager)
{
var authResult = await authenticationManager.AuthenticateAsync(ExternalCookieName);
if (authResult == null)
return null;
...
AuthenticationManager可以是Google,Facebook等程序包中IAuthenticationManager的任何实现。问题在于它们都失败并返回空对象,因此应用程序无法登录用户。

我一直想知道我不了解的OWIN配置是否有所更改。记录在这里:https://github.com/POPWorldMedia/POPForums/blob/v13.0.0/PopForums/Configuration/PopForumsOwinStartup.cs
using System;
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.Cookies;
using Owin;
using PopForums.ExternalLogin;
using PopForums.Services;
using PopForums.Web;
namespace PopForums.Configuration
{
public class PopForumsOwinStartup
{
public void Configuration(IAppBuilder app)
{
var setupService = PopForumsActivation.ServiceLocator.GetInstance<ISetupService>();
if (!setupService.IsDatabaseSetup())
return;
var settings = PopForumsActivation.ServiceLocator.GetInstance<ISettingsManager>().Current;
app.SetDefaultSignInAsAuthenticationType(ExternalAuthentication.ExternalCookieName);
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = ExternalAuthentication.ExternalCookieName,
AuthenticationMode = AuthenticationMode.Passive,
CookieName = CookieAuthenticationDefaults.CookiePrefix + ExternalAuthentication.ExternalCookieName,
ExpireTimeSpan = TimeSpan.FromMinutes(60)
});
if (settings.UseTwitterLogin)
app.UseTwitterAuthentication(
consumerKey: settings.TwitterConsumerKey,
consumerSecret: settings.TwitterConsumerSecret);
if (settings.UseMicrosoftLogin)
app.UseMicrosoftAccountAuthentication(
clientId: settings.MicrosoftClientID,
clientSecret: settings.MicrosoftClientSecret);
if (settings.UseFacebookLogin)
app.UseFacebookAuthentication(
appId: settings.FacebookAppID,
appSecret: settings.FacebookAppSecret);
if (settings.UseGoogleLogin)
app.UseGoogleAuthentication(settings.GoogleClientId, settings.GoogleClientSecret);
}
}
}
有任何想法吗?
最佳答案
不确定这是否有帮助,但是如果您查看模板,请使用AuthenticationManager.ExternalLinkLoginInfoAsync()来检索OAuth回调上的结果。你能检查一下我吗
[AllowAnonymous]
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> ExternalLinkLogin(string provider) //Google,Twitter etc.
{
return new ChallengeResult(provider, Url.Action("ExternalLinkLoginCallback"), userId);
}
[AllowAnonymous]
[HttpGet]
public async Task<ActionResult> ExternalLinkLoginCallback()
{
// Handle external Login Callback
var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync(XsrfKey,userId);
if (loginInfo == null)
{
IdentitySignout(); // to be safe we log out
return RedirectToAction("Register", new {message = "Unable to authenticate with external login."});
}
...
IdentitySignIn(userId, userName, returnUrl);
}
而且看起来您的启动代码与默认模板略有不同。
您正在使用:
app.SetDefaultSignInAsAuthenticationType(ExternalAuthentication.ExternalCookieName);
默认模板使用的位置:
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
您可以在我的一篇博客文章的摘要中快速比较模板使用的内容:

听到这让您感到沮丧的消息令人非常沮丧-这些东西应该向后兼容-使用这样的核心系统组件破坏现有的代码是不正确的。
关于c# - 将OWIN从2.1更新到3.0.1会中断外部身份验证,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/28704700/
