C#使用FluentHttpClient实现请求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:
调用结果
