KeenConveyance

1. Intro

A Asp.Net Core Controller service call RPC framework based on interface. 基于 interfaceAsp.Net Core Controller 服务调用RPC框架。

  • 服务端基于 Asp.Net CoreController. 支持所有标准的 Controller 功能, 如 FilterAuthenticationAuthorization等(*);
  • 客户端基于 Microsoft.Extensions.HttpSourceGenerator. 无运行时动态代码生成, 支持 Microsoft.Extensions.Http 丰富的拓展 (Polly链路追踪等);
  • 数据交换格式易拓展, 不局限于 Json, 可拓展为任意编码如: MemoryPackMessagePack 等;
  • 动态 Controller 选择. 支持选择指定类型注册为 Controller 并暴露 HttpAPI;
  • 基于约定的客户端代码生成. 不依赖类库共享;
  • 目标框架 net6.0+;

NOTE!!!

  • 虽然支持所有标准的 Controller 功能且执行其流程, 但框架并非按照 Controller 定义进行请求, 框架的请求中会忽略 [FromQuery][FromRoute] 等定义直接使用 ModelBinderBody 进行绑定;
    • 即: 如果请求由框架发起, 则依赖原始 HttpContext 信息的功能可能不能正常工作, 例如请求的 QueryPath 中不包含 Action 的信息;
  • 方法参数建议使用简单类型或 DTO: 除 CancellationToken 外, 客户端会将方法参数都序列化后传递给服务端,服务端从 Body 进行绑定, 对一些特殊的参数不支持如 IFormFile 等;
  • 框架对接口定义的 命名空间方法名称参数类型参数顺序 强依赖, 需要保证客户端与服务端接口定义一致;

2. 快速开始

2.1 服务端

  • 新建 Asp.Net Core Web API 项目, 并引用包:
<ItemGroup>
  <PackageReference Include="KeenConveyance.AspNetCore" Version="1.0.0-*" />
</ItemGroup>
  • 新建 IApplicationService 接口用于标记服务, 以便后续筛选 (非强制要求)
public interface IApplicationService
{ }
  • 配置 KeenConveyance 服务
services.AddKeenConveyance()
        .ConfigureService(options =>
        {
            //筛选所有派生自 IApplicationService 的类型作为 Controller
            options.ControllerSelectPredicate = typeInfo => typeInfo.IsAssignableTo(typeof(IApplicationService));
        });
  • 在请求管道中启用 KeenConveyance
// 在 MapControllers 之前 UseAuthorization 之后
app.UseKeenConveyance();
  • 定义服务接口并实现服务 (或使现有 Controller 派生自服务接口), 如:
public interface ISampleService : IApplicationService
{
    public Task<string> EchoAsync(string value, CancellationToken cancellationToken);
}

[Route("[controller]")]
public class SampleService : ISampleService
{
    [HttpGet]
    public Task<string> EchoAsync(string value, CancellationToken cancellationToken)
    {
        var echo = new string(value.AsEnumerable().Reverse().ToArray());
        return Task.FromResult(echo);
    }
}

2.2 客户端

  • 新建任意类型项目 (需要 DI 支持, 可能需要手动引入), 并引用包:
<ItemGroup>
  <PackageReference Include="KeenConveyance" Version="1.0.0-*" />
</ItemGroup>

Note: 项目直接引用而不要间接引用!

  • 配置 KeenConveyance 服务
services.AddKeenConveyance(options =>
        {
            //var xxxSerializer = 自定义的序列化器;
            //options.DefaultObjectSerializer = xxxSerializer; //设置默认序列化器
            //options.ObjectSerializers.Add(xxxSerializer); //添加到可用序列化器
        })
        .ConfigureClient(builder =>
        {
            //客户端全局配置
            builder.GlobalOptions(options =>
            {
                //options.ObjectSerializer = xxx;   //配置客户端全局使用的序列化器
                //options.HttpRequestMessageConstructor = xxx;  //配置客户端全局使用的HttpRequestMessage构造器
                //options.ServiceAddressProvider = xxx; //配置客户端全局使用的服务地址提供器
                //options.PrePreparePayloadData = true; //配置客户端请求时预准备请求数据,以确保Http请求包含有效的 Content-Length 头
                //options.BufferInitialCapacity = 1024; //配置客户端预准备请求数据时的Buffer初始化大小
            });

            //配置客户端
            //必须在此调用 BeginSetupClients 方法,并链式调用 AddClient 使用服务接口定义添加客户端, 并在最终调用 CompleteClientsSetup 方法
            builder.BeginSetupClients()
                   .AddClient<ISampleService>(httpClientBuilder =>
                   {
                       //配置服务地址
                       httpClientBuilder.ConfigureServiceAddress("http://127.0.0.1:5225");  //必须配置客户端的服务地址

                       // 在此进行 ISampleService 的 HttpClient 配置

                       httpClientBuilder.ConfigureOptions(options =>
                       {
                           //配置应用于当前客户端的配置
                       });
                   })
                   .CompleteClientsSetup();  //必须在最后调用 CompleteClientsSetup 方法,提示未找到此方法可尝试手动using当前项目的根命名空间
        });

至此已完成所有配置,从 DI 容器中直接获取 ISampleService 实例并调用方法即可


3. 自定义数据交换格式

框架默认使用 System.Text.Json 进行数据交换,通过实现自定义的 IObjectSerializer 来自定义数据交换格式;

  • 可参考测试代码对 MemoryPack 的支持;

其他

  • 客户端代码生成在当前项目的根命名空间下,提示未找到 CompleteClientsSetup 方法可以手动 using 当前项目的根命名空间进行尝试;
  • 生成的客户端代码都已标记为 partial 类型, 可声明对应的 partial 类,并重写方法来进行自定义操作, 服务的代理类型为格式为 {ServiceName}ProxyClient (如 ISampleService 的代理类型为 ISampleServiceProxyClient) :
     internal static partial class GeneratedClient
     {
         private partial class ISampleServiceProxyClient
         {
             public override Task<string> EchoAsync(string value, CancellationToken cancellationToken)
             {
                 //进行请求前后的自定义操作
                 return base.EchoAsync(value, cancellationToken);
             }
         }
     }
