這篇文章主要介紹了.net core 1.0 實現單點登錄負載多服務器的相關資料，非常不錯，具有參考借鑒價值，感興趣的朋友可以參考下

前言

.net core 出來有一時間了，這段時間也一直在做技術準備，目前想做一個單點登錄（SSO）系統，在這之前用.net時我用習慣了machineKey ,也順手在.net core 中嘗試了一上，結果發現不好使了，也不起作用，于是開始了網上學習。

實現方法

功夫不負有心人，網上高人還是多，在github.com上面ISSUES中也有人在討論此問題，于是找到代碼嘗試，結果實現了。

直接上代碼，我們需要先封裝一個XmlRepository，Key的格式如下：

<?xml version="1.0" encoding="utf-8"?>

<key id="cbb8a41a-9ca4-4a79-a1de-d39c4e307d75" version="1">

 <creationDate>2016-07-23T10:09:49.1888876Z</creationDate>

 <activationDate>2016-07-23T10:09:49.1388521Z</activationDate>

 <expirationDate>2116-10-21T10:09:49.1388521Z</expirationDate>

 <descriptor deserializerType="Microsoft.AspNetCore.DataProtection.AuthenticatedEncryption.ConfigurationModel.AuthenticatedEncryptorDescriptorDeserializer, Microsoft.AspNetCore.DataProtection, Version=1.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60">

  <descriptor>

   <encryption algorithm="AES_256_CBC" />

   <validation algorithm="HMACSHA256" />

   <masterKey p4:requiresEncryption="true" xmlns:p4="http://schemas.asp.net/2015/03/dataProtection">

    <!-- Warning: the key below is in an unencrypted form. -->

    <value>WYgZNh/3dOKRYJ1OAhVqs56pWPMHei15Uj44DPLWbYUiCpNVEBwqDfYAUq/4jBKYrNoUbaRkGY5o/NZ6a2NTwA==</value>

   </masterKey>

  </descriptor>

 </descriptor>

</key>

XmlRepository代碼：

public class CustomFileXmlRepository : IXmlRepository

  {

    private readonly string filePath = @"C:\keys\key.xml";

    public virtual IReadOnlyCollection<XElement> GetAllElements()

    {

      return GetAllElementsCore().ToList().AsReadOnly();

    }

    private IEnumerable<XElement> GetAllElementsCore()

    {

      yield return XElement.Load(filePath);

    }

    public virtual void StoreElement(XElement element, string friendlyName)

    {

      if (element == null)

      {

        throw new ArgumentNullException(nameof(element));

      }

      StoreElementCore(element, friendlyName);

    }

    private void StoreElementCore(XElement element, string filename)

    {

    }

  }

Startup代碼：

public class Startup

  {

    public Startup(IHostingEnvironment env)

    {

      var builder = new ConfigurationBuilder()

        .SetBasePath(env.ContentRootPath)

        .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)

        .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)

        .AddEnvironmentVariables();

      Configuration = builder.Build();

    }

    public IConfigurationRoot Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.

    public void ConfigureServices(IServiceCollection services)

    {

      services.AddSingleton<IXmlRepository, CustomFileXmlRepository>();

      services.AddDataProtection(configure =>

      {

        configure.ApplicationDiscriminator = "Htw.Web";

      });

      // Add framework services.

      services.AddMvc();

    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)

    {

      loggerFactory.AddConsole(Configuration.GetSection("Logging"));

      loggerFactory.AddDebug();

      if (env.IsDevelopment())

      {

        app.UseDeveloperExceptionPage();

        app.UseBrowserLink();

      }

      else

      {

        app.UseExceptionHandler("/Home/Error");

      }

      app.UseStaticFiles();

      app.UseCookieAuthentication(new CookieAuthenticationOptions()

      {

        AuthenticationScheme = CookieAuthenticationDefaults.AuthenticationScheme,

        LoginPath = new PathString("/Account/Unauthorized/"),

        AccessDeniedPath = new PathString("/Account/Forbidden/"),

        AutomaticAuthenticate = true,

        AutomaticChallenge = false,

        CookieHttpOnly = true,

        CookieName = "MyCookie",

        ExpireTimeSpan = TimeSpan.FromHours(2),

#if !DEBUG

        CookieDomain="h.cn",

#endif

        DataProtectionProvider = null

      });

      app.UseMvc(routes =>

      {

        routes.MapRoute(

          name: "default",

          template: "{controller=Home}/{action=Index}/{id?}");

      });

    }

  }

登錄代碼：

public async void Login()

  {

    if (!HttpContext.User.Identities.Any(identity => identity.IsAuthenticated))

    {

      var user = new ClaimsPrincipal(new ClaimsIdentity(new[] { new Claim(ClaimTypes.Name, "bob") }, CookieAuthenticationDefaults.AuthenticationScheme));

      await HttpContext.Authentication.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, user);

      HttpContext.Response.ContentType = "text/plain";

      await HttpContext.Response.WriteAsync("Hello First timer");

    }

    else

    {

      HttpContext.Response.ContentType = "text/plain";

      await HttpContext.Response.WriteAsync("Hello old timer");

    }

  }

注意

C:\keys\key.xml 這個文件路徑可以更改，還有就是也可用共享目錄或數據庫來實現統一管理到此可以登錄試一下。
