.net core 1.0 实现单点登录负载多服务器

前端技术 2023/09/02 .NET

前言

　　.net core 出来有一时间了，这段时间也一直在做技术准备，目前想做一个单点登录（SSO）系统，在这之前用.net时我用习惯了machineKey ,也顺手在.net core 中尝试了一上，结果发现不好使了，也不起作用，于是开始了网上学习。

实现方法

　　功夫不负有心人，网上高人还是多，在github.com上面ISSUES中也有人在讨论此问题，于是找到代码尝试，结果实现了。

　　直接上代码，我们需要先封装一个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代码：

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代码：

 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?}\");
      });
    }
  }

登录代码：

  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 这个文件路径可以更改，还有就是也可用共享目录或数据库来实现统一管理

到此可以登录试一下。

以上所述是小编给大家介绍的.net core 1.0 实现单点登录负载多服务器的全部叙述，希望对大家有所帮助！
