環境：
vs2019 16.5.1
aspnetcore 3.1.1
fiddler
restsharp 106.10.1
說明：
要測試restsharp的功能，首先需要了解http傳參和下載上傳文件的原理，請參考：
c#：從http請求報文看http協議中參數傳遞的幾種方式
c#使用Http上傳下載文件
一、restsharp介紹
RestSharp是一個輕量的，不依賴任何第三方的組件或者類庫的Http的組件。RestSharp具體以下特性：
1、支持.NET 3.5+,Silverlight 4, Windows Phone 7, Mono, MonoTouch, Mono for Android, Compact Framework 3.5,.NET Core等
2、通過NuGet方便引入到任何項目 ( Install-Package restsharp )
3、可以自動反序列化XML和JSON
4、支持自定義的序列化與反序列化
5、自動檢測返回的內容類型
6、支持HTTP的GET, POST, PUT, HEAD, OPTIONS, DELETE等操作
7、可以上傳多文件
8、支持oAuth 1, oAuth 2, Basic, NTLM and Parameter-based Authenticators等授權驗證等
9、支持異步操作
10、極易上手並應用到任何項目中
以上是RestSharp的主要特點，通用它你可以很容易地用程序來處理一系列的網絡請求（GET, POST, PUT, HEAD, OPTIONS, DELETE），並得到返回結果。

二、首先准備webapi項目
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
namespace testweb.Controllers
{
[ApiController]
[Route("[controller]/[action]")]
public class TestController : ControllerBase
{
public async Task<IEnumerable<object>> TestGet()
{
return new object[] { new { Name = "小明", age = 20 }, new { Name = "小花", age = 18 } };
}
public async Task<IEnumerable<object>> TestPost()
{
return new object[] { new { Name = "post小明", age = 20 }, new { Name = "post小花", age = 18 } };
}
[HttpGet]
[HttpPost]
public async Task<string> TestUrlPara([FromQuery]string name, [FromQuery]int? age)
{
return $"hello {name},你{age}歲了!";
}
[HttpPost]
public async Task<string> TestPostUrlFormUrlencoded([FromForm]string name, [FromForm]int? age)
{
return $"hello {name},你{age}歲了!";
}
[HttpPost]
public async Task<string> TestPostUrlFormData([FromForm]string name, [FromForm]int? age)
{
return $"hello {name},你{age}歲了,你上傳了{Request.Form.Files.Count}個文件!";
}
[HttpPost]
public string TestBodyJson([FromBody]User user)
{
if (user == null) return "user is null.";
return Newtonsoft.Json.JsonConvert.SerializeObject(user);
}
[HttpGet]
public IActionResult TestDownLoad()
{
var filepath = @"C:\Users\AUAS\Pictures\百度下載圖片\timg.jpg";
FileStream fs = new FileStream(filepath, FileMode.Open);
return File(fs, "application/octet-stream", "test.png");
}
}
public class User
{
public string name { get; set; }
public int? id { get; set; }
}
}
三、開始測試restsharp發送各種類型http請求和下載文件
3.1 首先nuget包引入restsharp
3.2 直接看測試代碼
using RestSharp;
using System;
using System.IO;
namespace restsharpdemo
{
class Program
{
private static RestClient client = new RestClient("http://localhost:5000/");
static void Main(string[] args)
{
//TestGet();
//TestPost();
//TestUrlPara();
//TestPostUrlFormUrlencoded();
//TestPostUrlFormData();
//TestBodyJson();
//TestDownLoad();
Console.WriteLine("Hello World!");
Console.ReadLine();
}
/// <summary>
/// 測試下載文件
/// </summary>
private static void TestDownLoad()
{
string tempFile = Path.GetTempFileName();
using (var writer = File.OpenWrite(tempFile))
{
var req = new RestRequest("test/TestDownLoad", Method.GET);
req.ResponseWriter = responseStream =>
{
using (responseStream)
{
responseStream.CopyTo(writer);
}
};
var response = client.DownloadData(req);
}
}
/// <summary>
/// 測試傳遞application/json類型參數
/// </summary>
private static void TestBodyJson()
{
var req = new RestRequest("test/TestBodyJson", Method.POST);
req.AddJsonBody(new { name = "小花", id = 23 });
var res = client.Execute(req);
if (res.IsSuccessful)
{
Console.WriteLine($"成功:{res.Content}");
}
else
{
if (res.StatusCode == 0)
{
Console.WriteLine($"失敗:網絡錯誤:{res.ErrorMessage}");
}
else
{
Console.WriteLine($"失敗:{(int)res.StatusCode}-{res.StatusDescription}");
}
}
}
/// <summary>
/// 測試傳遞post multipart/form-data參數
/// </summary>
private static void TestPostUrlFormData()
{
var req = new RestRequest("test/TestPostUrlFormData", Method.POST);
req.AlwaysMultipartFormData = true;
req.AddParameter("name", "小明");
req.AddParameter("age", "20");
req.AddFile("file1", @"C:\Users\AUAS\Pictures\百度下載圖片\timg.jpg");
var res = client.Execute(req);
if (res.IsSuccessful)
{
Console.WriteLine($"成功:{res.Content}");
}
else
{
if (res.StatusCode == 0)
{
Console.WriteLine($"失敗:網絡錯誤:{res.ErrorMessage}");
}
else
{
Console.WriteLine($"失敗:{(int)res.StatusCode}-{res.StatusDescription}");
}
}
}
/// <summary>
/// 測試傳遞post application/x-www-form-urlencoded參數
/// </summary>
private static void TestPostUrlFormUrlencoded()
{
var req = new RestRequest("test/TestPostUrlFormUrlencoded", Method.POST);
//將參數編碼后加到url上
req.AddHeader("Content-Type", "application/x-www-form-urlencoded");
req.AddParameter("name", "小明");
req.AddParameter("age", "20");
var res = client.Execute(req);
if (res.IsSuccessful)
{
Console.WriteLine($"成功:{res.Content}");
}
else
{
if (res.StatusCode == 0)
{
Console.WriteLine($"失敗:網絡錯誤:{res.ErrorMessage}");
}
else
{
Console.WriteLine($"失敗:{(int)res.StatusCode}-{res.StatusDescription}");
}
}
}
/// <summary>
/// 測試傳遞url參數
/// </summary>
private static void TestUrlPara()
{
var req = new RestRequest("test/TestUrlPara", Method.GET);
req = new RestRequest("test/TestUrlPara", Method.POST);
//將參數編碼后加到url上
req.AddParameter("name", "小明");
req.AddParameter("age", "18");
var res = client.Get(req);
if (res.IsSuccessful)
{
Console.WriteLine($"成功:{res.Content}");
}
else
{
if (res.StatusCode == 0)
{
Console.WriteLine($"失敗:網絡錯誤:{res.ErrorMessage}");
}
else
{
Console.WriteLine($"失敗:{(int)res.StatusCode}-{res.StatusDescription}");
}
}
}
/// <summary>
/// 測試簡單post
/// </summary>
private static void TestPost()
{
var req = new RestRequest("test/testpost", Method.POST);
var res = client.Post(req);
if (res.IsSuccessful)
{
Console.WriteLine($"成功:{res.Content}");
}
else
{
if (res.StatusCode == 0)
{
Console.WriteLine($"失敗:網絡錯誤:{res.ErrorMessage}");
}
else
{
Console.WriteLine($"失敗:{(int)res.StatusCode}-{res.StatusDescription}");
}
}
}
/// <summary>
/// 測試簡單get
/// </summary>
private static void TestGet()
{
var req = new RestRequest("test/testget", Method.GET);
var res = client.Get(req);
if (res.IsSuccessful)
{
Console.WriteLine($"成功:{res.Content}");
}
else
{
if (res.StatusCode == 0)
{
Console.WriteLine($"失敗:網絡錯誤:{res.ErrorMessage}");
}
else
{
Console.WriteLine($"失敗:{(int)res.StatusCode}-{res.StatusDescription}");
}
}
}
}
}
