C# 使用FluentHttpClient请求WebApi

写在前面

FluentHttpClient 是一个REST API 异步调用 HTTP 客户端，调用过程非常便捷，采用流式编程，可以将所有请求所需的参数一次性发送，并直接获取序列化后的结果。

老规矩从NuGet上安装该类库：

这边一定要认准是 Pathoschild 这家，千万不要下错，因为有类似关键词的类库。

代码实现


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这边直接使用了官方的.NetCore WebApi模板项目，运行框架是.Net8.0，现在已经集成了Swagger，超级赞的，运行起来可以直接看到这样的界面。

对应的控制器代码如下：

    [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();}}

运行起来：
