這篇文章主要介紹了.net core 1.0 實(shí)現(xiàn)單點(diǎn)登錄負(fù)載多服務(wù)器的相關(guān)資料，非常不錯(cuò)，具有參考借鑒價(jià)值，感興趣的朋友可以參考下

前言

.net core 出來(lái)有一時(shí)間了，這段時(shí)間也一直在做技術(shù)準(zhǔn)備，目前想做一個(gè)單點(diǎn)登錄（SSO）系統(tǒng)，在這之前用.net時(shí)我用習(xí)慣了machineKey ,也順手在.net core 中嘗試了一上，結(jié)果發(fā)現(xiàn)不好使了，也不起作用，于是開(kāi)始了網(wǎng)上學(xué)習(xí)。

實(shí)現(xiàn)方法

功夫不負(fù)有心人，網(wǎng)上高人還是多，在github.com上面ISSUES中也有人在討論此問(wèn)題，于是找到代碼嘗試，結(jié)果實(shí)現(xiàn)了。

直接上代碼，我們需要先封裝一個(gè)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(gè)文件路徑可以更改，還有就是也可用共享目錄或數(shù)據(jù)庫(kù)來(lái)實(shí)現(xiàn)統(tǒng)一管理到此可以登錄試一下。

以上所述是小編給大家介紹的.net core 1.0 實(shí)現(xiàn)單點(diǎn)登錄負(fù)載多服務(wù)器的全部敘述，希望對(duì)大家有所幫助！
