ABP微服务系列学习-搭建自己的微服务结构（三）

上一篇我们基础服务初步搭建完毕，接下来我们整一下认证和网关。

搭建认证服务

认证服务的话，ABP CLI生成的所有模板都包括了一个AuthServer。我们直接生成模板然后微调一下就可以直接用了。

abp new FunShow -t app --tiered

使用命令创建模板后，我们可以找到一个AuthServer。把项目移动到Apps目录下，然后我们开始改造一下这个项目。
首先修改项目文件的引用配置
修改EFCore项目引用为AdministrationService.EntityFrameworkCore和IdentityService.EntityFrameworkCore，
然后添加Shared.Localization和Shared.Hosting.AspNetCore项目引用，别的基本不用怎么修改，完整项目配置为：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <Import Project="..\..\..\..\common.props" />

  <PropertyGroup>
    <TargetFramework>net7.0</TargetFramework>
    <UserSecretsId>b83bc18b-a6ca-4e2d-a827-26ffaff35dce</UserSecretsId>
    <DockerDefaultTargetOS>Linux</DockerDefaultTargetOS>
    <DockerfileContext>..\..\..\..</DockerfileContext>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.DataProtection.StackExchangeRedis" Version="6.0.5" />
    <PackageReference Include="Microsoft.VisualStudio.Azure.Containers.Tools.Targets" Version="1.17.0" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Volo.Abp.Caching.StackExchangeRedis" Version="7.0.0" />
    <PackageReference Include="Volo.Abp.EventBus.RabbitMQ" Version="7.0.0" />
    <PackageReference Include="Volo.Abp.BackgroundJobs.RabbitMQ" Version="7.0.0" />
    <PackageReference Include="Volo.Abp.Account.Web.OpenIddict" Version="7.0.0" />
    <PackageReference Include="Volo.Abp.Account.Application" Version="7.0.0" />
    <PackageReference Include="Volo.Abp.Account.HttpApi" Version="7.0.0" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\..\..\..\services\administration\src\FunShow.AdministrationService.EntityFrameworkCore\FunShow.AdministrationService.EntityFrameworkCore.csproj" />
    <ProjectReference Include="..\..\..\..\services\identity\src\FunShow.IdentityService.EntityFrameworkCore\FunShow.IdentityService.EntityFrameworkCore.csproj" />
    <ProjectReference Include="..\..\..\..\shared\FunShow.Shared.Hosting.AspNetCore\FunShow.Shared.Hosting.AspNetCore.csproj" />
    <ProjectReference Include="..\..\..\..\shared\FunShow.Shared.Localization\FunShow.Shared.Localization.csproj" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Volo.Abp.AspNetCore.Mvc.UI.Theme.LeptonXLite" Version="2.0.0-*" />
  </ItemGroup>

  <ItemGroup>
    <Compile Remove="Logs\**" />
    <Content Remove="Logs\**" />
    <EmbeddedResource Remove="Logs\**" />
    <None Remove="Logs\**" />
  </ItemGroup>

</Project>

然后修改Program文件，主要是日志配置修改一下，别的不用改动

using System;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using FunShow.Shared.Hosting.AspNetCore;
using Serilog;

namespace FunShow.AuthServer;

public class Program
{
    public async static Task<int> Main(string[] args)
    {
        var assemblyName = typeof(Program).Assembly.GetName().Name;

        SerilogConfigurationHelper.Configure(assemblyName);

        try
        {
            Log.Information($"Starting {assemblyName}.");
            var builder = WebApplication.CreateBuilder(args);
            builder.Host
                .AddAppSettingsSecretsJson()
                .UseAutofac()
                .UseSerilog();
            await builder.AddApplicationAsync<FunShowAuthServerModule>();
            var app = builder.Build();
            await app.InitializeApplicationAsync();
            await app.RunAsync();
            return 0;
        }
        catch (Exception ex)
        {
            Log.Fatal(ex, $"{assemblyName} terminated unexpectedly!");
            return 1;
        }
        finally
        {
            Log.CloseAndFlush();
        }
    }
}

    }

    private void ConfigureSameSiteCookiePolicy(ServiceConfigurationContext context)
    {
    	context.Services.AddSameSiteCookiePolicy();
    }
}

最后修改配置文件

{
  "App": {
    "SelfUrl": "https://localhost:44322",
    "CorsOrigins": "http://localhost:4200,http://localhost:9527,https://localhost:44307,https://localhost:44325,https://localhost:44353,https://localhost:44367,https://localhost:44388,https://localhost:44381,https://localhost:44361",
    "RedirectAllowedUrls": "http://localhost:4200,https://localhost:44307,https://localhost:44321,http://localhost:9527"
  },
  "AuthServer": {
    "Authority": "https://localhost:44322",
    "RequireHttpsMetadata": "true",
    "SwaggerClientId": "WebGateway_Swagger"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "ConnectionStrings": {
    "AdministrationService": "Host=localhost;Port=5432;User ID=postgres;password=myPassw0rd;Pooling=true;Database=FunShow_Administration;",
    "IdentityService": "Host=localhost;Port=5432;User ID=postgres;password=myPassw0rd;Pooling=true;Database=FunShow_Identity;"
  },
  "StringEncryption": {
    "DefaultPassPhrase": "fCrJICTG3WoyissG"
  },
  "Redis": {
    "Configuration": "localhost:6379"
  },
  "RabbitMQ": {
    "Connections": {
      "Default": {
        "HostName": "localhost"
      }
    },
    "EventBus": {
      "ClientName": "FunShow_AuthServer",
      "ExchangeName": "FunShow"
    }
  },
  "ElasticSearch": {
    "Url": "http://localhost:9200"
  }
}

这样我们认证服务即修改完成。

搭建网关服务

网关服务我们直接新建一个空asp.net core项目。
然后只需要添加一个我们的Shared.Hosting.Gateways项目引用即可。

<Project Sdk="Microsoft.NET.Sdk.Web">

  <Import Project="..\..\..\..\common.props" />

  <PropertyGroup>
    <TargetFramework>net7.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <ProjectReference Include="..\..\..\..\shared\FunShow.Shared.Hosting.Gateways\FunShow.Shared.Hosting.Gateways.csproj" />
  </ItemGroup>

  <ItemGroup>
    <Compile Remove="Logs\**" />
    <Content Remove="Logs\**" />
    <EmbeddedResource Remove="Logs\**" />
    <None Remove="Logs\**" />
  </ItemGroup>

</Project>

修改Program.cs

using System;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using FunShow.Shared.Hosting.AspNetCore;
using Serilog;

namespace FunShow.WebGateway;

public class Program
{
    public async static Task<int> Main(string[] args)
    {
        var assemblyName = typeof(Program).Assembly.GetName().Name;

        SerilogConfigurationHelper.Configure(assemblyName);

        try
        {
            Log.Information($"Starting {assemblyName}.");
            var builder = WebApplication.CreateBuilder(args);
            builder.Host
                .AddAppSettingsSecretsJson()
                .AddYarpJson()
                .UseAutofac()
                .UseSerilog();
            await builder.AddApplicationAsync<FunShowWebGatewayModule>();
            var app = builder.Build();
            await app.InitializeApplicationAsync();
            await app.RunAsync();
            return 0;
        }
        catch (Exception ex)
        {
            Log.Fatal(ex, $"{assemblyName} terminated unexpectedly!");
            return 1;
        }
        finally
        {
            Log.CloseAndFlush();
        }
    }
}

这里和认证服务基本一致，就是多了一个AddYarpJson()来添加我们的yarp的配置文件。
在目录下新建yarp.json文件，添加我们的yarp配置内容。配置集群和路由如下：

{
  "ReverseProxy": {
    "Routes": {
      "Account Service": {
        "ClusterId": "accountCluster",
        "Match": {

        }
      },
      "Identity Service": {
        "ClusterId": "identityCluster",
        "Match": {
          "Path": "/api/identity/{**everything}"
        }
      },
      "Administration Service": {
        "ClusterId": "administrationCluster",
        "Match": {
          "Path": "/api/abp/{**everything}"
        }
      },
      "Logging Service": {
        "ClusterId": "loggingCluster",
        "Match": {
          "Path": "/api/LoggingService/{**everything}"
        }
      },
      "feature-management-route": {
        "ClusterId": "feature-management-cluster",
        "Match": {
          "Path": "/api/feature-management/{**everything}"
        }
      },
      "permission-management-route": {
        "ClusterId": "permission-management-cluster",
        "Match": {
          "Path": "/api/permission-management/{**everything}"
        }
      },
      "setting-management-route": {
        "ClusterId": "setting-management-cluster",
        "Match": {
          "Path": "/api/setting-management/{**everything}"
        }
      }
    },
    "Clusters": {
      "accountCluster": {
        "Destinations": {
          "destination1": {
            "Address": "https://localhost:44322"
          }
        }
      },
      "identityCluster": {
        "Destinations": {
          "destination1": {
            "Address": "https://localhost:44388"
          }
        }
      },
      "administrationCluster": {
        "Destinations": {
          "destination1": {
            "Address": "https://localhost:44367"
          }
        }
      },
      "loggingCluster": {
        "Destinations": {
          "destination1": {
            "Address": "https://localhost:45124"
          }
        }
      },
      "feature-management-cluster": {
        "Destinations": {
          "destination1": {
            "Address": "https://localhost:44367"
          }
        }
      },
      "permission-management-cluster": {
        "Destinations": {
          "destination1": {
            "Address": "https://localhost:44367"
          }
        }
      },
      "setting-management-cluster": {
        "Destinations": {
          "destination1": {
            "Address": "https://localhost:44367"
          }
        }
      }
    }
  }
}

在appsettings.json文件添加我们认证服务的地址

{
  "App": {
    "SelfUrl": "https://localhost:44325",
    "CorsOrigins": "http://localhost:4200,https://localhost:44307,http://localhost:9527"
  },
  "AuthServer": {
    "Authority": "https://localhost:44322",
    "RequireHttpsMetadata": "true",
    "SwaggerClientId": "WebGateway_Swagger"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "Redis": {
    "Configuration": "localhost:6379"
  },
  "ElasticSearch": {
    "Url": "http://localhost:9200"
  }
}

最后我们添加FunShowWebGatewayModule文件。配置我们yarp的服务。

UseSwaggerUIWithYarp是从我们Yarp配置文件中读取服务信息去构造swagger路由配置。
好了，到这我们认证服务和网关服务也搭建完毕，下一篇我们开始迁移数据库。
