Refit使用入门

前言

原文：Refit: The automatic type-safe REST library for .NET Core, Xamarin and .NET

百度翻译：Refit：适用于.NET Core、Xamarin和.NET的自动类型安全REST库

官方网站：https://github.com/reactiveui/refit

新建weapi项目并添加包Refit与Refit.HttpClientFactory

新建接口IGitHubApi.cs

using Refit;

namespace RefitDemo
{
    public interface IGitHubApi
    {
        [Get("/WeatherForecast")]
        Task<IEnumerable<WeatherForecast>> GetWeatherForecastList();
    }
}

修改Program.cs

builder.Services
    .AddRefitClient<IGitHubApi>()
    .ConfigureHttpClient(c => c.BaseAddress = new Uri("https://localhost:7159"));

这里的7159改成你的项目端口

修改WeatherForecastController.cs

using Microsoft.AspNetCore.Mvc;
using Refit;

namespace RefitDemo.Controllers
{
    [ApiController]
    [Route("[controller]")]
    public class WeatherForecastController : ControllerBase
    {
        private static readonly string[] Summaries = new[]
        {
            "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
        };

        private readonly ILogger<WeatherForecastController> _logger;
        private readonly IGitHubApi _gitHubApi;
        public WeatherForecastController(ILogger<WeatherForecastController> logger, IGitHubApi gitHubApi)
        {
            _logger = logger;
            _gitHubApi = gitHubApi;
        }

        [HttpGet(Name = "GetWeatherForecast")]
        public IEnumerable<WeatherForecast> Get()
        {
            return Enumerable.Range(1, 5).Select(index => new WeatherForecast
            {
                Date = DateOnly.FromDateTime(DateTime.Now.AddDays(index)),
                TemperatureC = Random.Shared.Next(-20, 55),
                Summary = Summaries[Random.Shared.Next(Summaries.Length)]
            })
            .ToArray();
        }

        [HttpPost(Name = "GetTest")]
        public async Task<IEnumerable<WeatherForecast>> GetTestAsync()
        {
            return await _gitHubApi.GetWeatherForecastList();
        }

        [HttpPost("GetTest1")]
        public async Task<IEnumerable<WeatherForecast>> GetTest1Async()
        {
            var gitHubApi = RestService.For<IGitHubApi>("https://localhost:7159");
            return await gitHubApi.GetWeatherForecastList();
        }
    }
}

这里代码就是这两种调用方式

        [HttpPost(Name = "GetTest")]
        public async Task<IEnumerable<WeatherForecast>> GetTestAsync()
        {
            return await _gitHubApi.GetWeatherForecastList();
        }

        [HttpPost("GetTest1")]
        public async Task<IEnumerable<WeatherForecast>> GetTest1Async()
        {
            var gitHubApi = RestService.For<IGitHubApi>("https://localhost:7159");
            return await gitHubApi.GetWeatherForecastList();
        }

后面两个api就是Refit的调用结果
