如何使用 Azure Active Directory 设置 Ocelot Api 网关

Question

我遵循了 this 教程并设法将 api 与 Azure Active Directory 结合使用身份验证和授权。

不过我想从 Ocelot Api 网关后面使用 api。我可以使用具有自定义基本授权的 ocelot，但无法与 Azure Active Directory 一起使用。

我已经将 Ocelot api 网关 url 添加到我的 api 重定向 url 列表中。

我应该如何在 config.json 和 Ocelot Api 网关项目 StartUp.cs 中设置 ReRoutes 值？

任何帮助将不胜感激。

Answer 1

最终我可以。首先感谢 ocelot 库，因为它支持 Azure Active Directory 授权。

我假设您已经完成了 this 教程。

1-像往常一样创建一个ocelot api网关项目。

2-将Microsoft.Identity.Web class库添加到ocelot项目作为参考

3-添加ocelot.json，它应该像下面的

    {
  "ReRoutes": [

    {
      "DownstreamPathTemplate": "/api/{catchAll}",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "localhost",
          "Port": 44351
        }
      ],
      "UpstreamPathTemplate": "/to-do-service/api/{catchAll}",

      "AuthenticationOptions": {
        "AuthenticationProviderKey": "AzureADJwtBearer",
        "AllowedScopes": []
      }
    }

  ],
  "GlobalConfiguration": {
    "BaseUrl": "http://localhost:7070",
    "RequestIdKey": "OcRequestId",
    "AdministrationPath": "/administration"
  }
}

4-编辑 Program.cs 中的 CreateWebHostBuilder 方法，以便 ocelot.json 用作附加配置源。

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
             .ConfigureAppConfiguration((hostingContext, config) =>
             {
                 config.AddJsonFile("ocelot.json", false, false);
             })
                .UseStartup<Startup>();

5-编辑 Startup.cs 中的 ConfigureServices 和 Configure 方法，如下所示

public void ConfigureServices(IServiceCollection services)
        {
            services.AddProtectWebApiWithMicrosoftIdentityPlatformV2(Configuration); //this extension comes from Microsoft.Identity.Web class library

            services.AddOcelot(Configuration);
            //services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public async void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            await app.UseOcelot();
        }

6-最后但同样重要的是，您应该将 AzureAd 配置添加到 ocelot api 网关项目。（参考教程应该和ToDoListService一样）她你可以看到一个例子 appsettings.json .

{
  "AzureAd": {
    "Instance": "https://login.microsoftonline.com/",
    "ClientId": "client-id-guid-from-azure-ad",

    /*
      You need specify the TenantId only if you want to accept access tokens from a single tenant (line of business app)
      Otherwise you can leave them set to common
    */
    "Domain": "blablabla.onmicrosoft.com", // for instance contoso.onmicrosoft.com. Not used in the ASP.NET core template
    "TenantId": "tenant-id-guid-from-azure-ad" // A guid (Tenant ID = Directory ID) or 'common' or 'organizations' or 'consumers'
  },
  "Logging": {
    "LogLevel": {
      "Default": "Warning"
    }
  },
  "AllowedHosts": "*"

}

我希望这个回答能节省一些人的时间，让他们的生活更快乐:)

编码愉快！

Answer 2

我无法在 "Microsoft.Identity.Web" 库中使用它。我收到了很多错误，例如：

AuthenticationScheme：AzureADCookie 未通过身份验证...

-- 和--

签名验证失败...

相反，我设法获得了 Azure B2C 令牌验证以及范围，工作如下：

1) ConfigureServices 方法 (Startup.cs):

    services.AddAuthentication(options =>
            {
                options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; 
             })
           .AddJwtBearer(jwtOptions =>
           {
               jwtOptions.Authority = $"{Configuration["AzureAdB2C:Instance"]}/tfp/{Configuration["AzureAdB2C:TenantId"]}/{Configuration["AzureAdB2C:SignUpSignInPolicyId"]}";
               jwtOptions.Audience = Configuration["AzureAdB2C:ClientId"];
               jwtOptions.TokenValidationParameters.ValidateIssuer = true; 
               jwtOptions.TokenValidationParameters.ValidIssuer = $"{Configuration["AzureAdB2C:Instance"]}/{Configuration["AzureAdB2C:TenantId"]}/v2.0/"; 
           }); 

            // Map scp to scope claims instead of http://schemas.microsoft.com/identity/claims/scope to allow ocelot to read/verify them
            JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Remove("scp");
            JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Add("scp", "scope");


2) Ocelot re-routing configuration:

     {
      "DownstreamPathTemplate": "/{everything}",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "master-api",
          "Port": 5000
        }
      ],
      "UpstreamPathTemplate": "/master-api/{everything}",
      "UpstreamHttpMethod": [ "POST", "PUT", "GET", "DELETE" ],
      "ReRoutesCaseSensitive": false,
      "AuthenticationOptions": {
        "AuthenticationProviderKey": "Bearer",
        "AllowedScopes": [ "master" ]
      }
    }

3) Azure AD B2C 配置 (appsettings.json):

  "AzureAdB2C": {
    "Instance": "https://yourdomain.b2clogin.com",
    "TenantId": "{tenantId}",
    "SignUpSignInPolicyId": "your_signin_policy",
    "ClientId": "{clientId}"
  }

希望对您有所帮助！ :)
