SyZero.Feign

SyZero 框架的声明式 HTTP 客户端模块，基于 Refit 实现类似 Spring Cloud OpenFeign 的功能。

📦 安装

dotnet add package SyZero.Feign

✨ 特性

  • 🚀 声明式调用 - 使用接口定义 HTTP 客户端
  • 💾 服务发现 - 集成服务注册与发现
  • 🔒 负载均衡 - 内置负载均衡支持
  • 🔄 gRPC 支持 - 同时支持 HTTP 和 gRPC 调用

🚀 快速开始

1. 配置 appsettings.json

{
  "Feign": {
    "Timeout": 30000,
    "RetryCount": 3
  }
}

2. 注册服务

// Program.cs
var builder = WebApplication.CreateBuilder(args);
// 添加SyZero
builder.AddSyZero();

// 注册服务方式1 - 使用默认配置
builder.Services.AddSyZeroFeign();

// 注册服务方式2 - 使用委托配置
builder.Services.AddSyZeroFeign(options =>
{
    options.Timeout = 30000;
    options.RetryCount = 3;
});

// 注册服务方式3 - 注册特定客户端
builder.Services.AddSyZeroFeign()
    .AddClient<IUserServiceClient>("user-service");

var app = builder.Build();
// 使用SyZero
app.UseSyZero();
app.Run();

3. 使用示例

[FeignClient("user-service")]
public interface IUserServiceClient
{
    [Get("/api/user/{id}")]
    Task<UserDto> GetUserAsync(long id);

    [Post("/api/user")]
    Task<UserDto> CreateUserAsync([Body] CreateUserInput input);
}

public class MyService
{
    private readonly IUserServiceClient _userClient;

    public MyService(IUserServiceClient userClient)
    {
        _userClient = userClient;
    }

    public async Task<UserDto> GetUserAsync(long id)
    {
        return await _userClient.GetUserAsync(id);
    }
}

📖 配置选项

属性 类型 默认值 说明
Timeout int 30000 请求超时时间（毫秒）
RetryCount int 3 重试次数
BaseUrl string "" 基础地址（不使用服务发现时）

📖 API 说明

FeignClient 特性

属性 说明
Name 服务名称（用于服务发现）
Url 固定地址（不使用服务发现）
FallbackType 降级处理类型

使用特性标记接口方法的 HTTP 方法和路径

🔧 高级用法

请求拦截器

builder.Services.AddSyZeroFeign()
    .AddInterceptor<AuthHeaderInterceptor>();

public class AuthHeaderInterceptor : IRequestInterceptor
{
    public Task InterceptAsync(HttpRequestMessage request)
    {
        request.Headers.Add("Authorization", "Bearer xxx");
        return Task.CompletedTask;
    }
}

gRPC 调用

[FeignClient("user-service", Protocol = Protocol.Grpc)]
public interface IUserGrpcClient
{
    Task<UserDto> GetUserAsync(long id);
}

⚠️ 注意事项

  1. 服务发现 - 使用服务名时需要配置服务发现组件
  2. 超时配置 - 根据业务合理配置超时时间
  3. 降级处理 - 建议实现 Fallback 以提高可用性
