.net core 1.0 实现单点登录负载多服务器

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。
