FluentHttpClient 是一個REST API 異步調用 HTTP 客戶端,調用過程非常便捷,下面我們就來學習一下C#如何使用FluentHttpClient實現請求WebApi吧

寫在前面

FluentHttpClient 是一個REST API 異步調用 HTTP 客戶端，調用過程非常便捷，采用流式編程，可以將所有請求所需的參數一次性發(fā)送，并直接獲取序列化后的結果。

老規(guī)矩從NuGet上安裝該類庫：

這邊一定要認準是 Pathoschild 這家，千萬不要下錯，因為有類似關鍵詞的類庫。

代碼實現

 
using Pathoschild.Http.Client;
using System;
 
class Program
{
    static async Task Main(string[] args)
    {
        var client = new FluentClient("http://localhost:5000/");
        var items = await client.GetAsync("WeatherForecast")
            .WithHeader("User-Agent", "Tester")
            .WithArguments(new { page = 1, page_size = 10, target = "Day" })
            .As<List<WeatherForecast>>();
        //var items = await client.PostAsync("WeatherForecast").As<List<WeatherForecast>>();
        foreach (var item in items)
        {
            await Console.Out.WriteLineAsync($"Date: {item.Date.ToShortDateString()}, Summary: {item.Summary}");
        }
 
        Console.ReadLine();
    }
 
    public class WeatherForecast
    {
        public DateOnly Date { get; set; }
 
        public int TemperatureC { get; set; }
 
        public int TemperatureF { get; set; }
 
        public string? Summary { get; set; }
    }
}

WebApi這邊直接使用了官方的.NetCore WebApi模板項目，運行框架是.Net8.0，現在已經集成了Swagger，超級贊的，運行起來可以直接看到這樣的界面。

對應的控制器代碼如下：

    [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;
 
        public WeatherForecastController(ILogger<WeatherForecastController> logger)
        {
            _logger = logger;
        }
 
        [HttpGet(Name = "GetWeatherForecast")]
        [HttpPost(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();
        }
    }

運行起來：
