Nancy一個輕量級Web Framework。
最近我需要模擬http response，我需要快速建立一個http server，
透過谷哥發現Nancy符合我要的快速、輕量、簡單原則，
同時一些我需要的基本功能，如診斷儀表板、驗證、SSL..等一應俱全，
也支援DELETE, GET, HEAD, OPTIONS, POST, PUT and PATCH動詞，
不多說，馬上示範如何快速建立一個http Server。
先透過NG安裝
Install-Package Nancy.Hosting.Self
實務上我寫一隻Windows Service，但這裡我使用Console application示範。
class Program
{
string URL = "http://localhost";
int PORT =9487;
NancyHost _NancyHost;
public Program()
{
var uri = new Uri($"{URL}:{PORT}/");
//var hostConfiguration = new HostConfiguration();
_NancyHost = new NancyHost(uri);
}
private void Start()
{
_NancyHost.Start();
Console.WriteLine($"Started listennig.... {URL}:{PORT}");
Console.ReadKey();
_NancyHost.Stop();
}
static void Main(string[] args)
{
var p = new Program();
p.Start();
}
}
執行後你會看到Nancy啟動錯誤，這是因為權限問題，你可以透過CreateAutomatically自動保留URL，
或是使用Administrator啟動，另外就是手動建立註冊URL保留區。
netsh http add urlacl url="http://+:9487/" user="Everyone"
查看URL保留區: netsh http show urlacl
再次執行即可正常啟動Nancy
開啟browser輸入http://localhost:9487，即可看到http server返回404
撰寫Request
所有Request都必須繼承NancyModule，下面我建立post和Get兩個動詞。
public class TestModule : NancyModule
{
public TestModule()
{
Get["/"] = _ => "Hello Nancy from Get request";
Post["/"] = _ => "Hello Nancy from Post request";
}
}
Html、Htm、SSHtml測試
View:
Get["/Home"] = Post["/Home"] = parameters =>
{
var usersmodel = new List<User>();
usersmodel.Add(new User { Name = "rico" });
usersmodel.Add(new User { Name = "sherry" });
this.ViewBag.data = "From Nancy";
return View["Index.sshtml", usersmodel];
};
參數測試
Get["/User/{Name}"] = p =>
{
if (p.Name =="rico" )
return $"Admini user #{p.Name}!";
else
return $"Normal user #{p.Name}!";
};
Request Body傳送JSON格式測試
Post["/"] = _ =>
{
var Name = this.Request.Body;
var length = this.Request.Body.Length;
var data = new byte[length];
Name.Read(data, 0, (int)length);
var body = System.Text.Encoding.Default.GetString(data);
var requestPOCO = JsonConvert.DeserializeObject<User>(body);//Install-Package Nancy.Serialization.JsonNet
return $"Name:{requestPOCO.Name}#Age:{requestPOCO.Age}#IsAdmin:{requestPOCO.IsAdmin}";
};
Model Binding測試
Post["/"] = _ =>
{
var requestPOCO = this.Bind<User>();
return $"Name:{requestPOCO.Name}";
};
自訂header的response測試
Post["/Rico"] = _ =>
{
string jsonString = "{ Name: \"Rico\", Age: \"35\" }";
byte[] jsonBytes = Encoding.UTF8.GetBytes(jsonString);
return new Response()
{
StatusCode = HttpStatusCode.OK,
ContentType = "application/json",
ReasonPhrase = "Rico Customize",
Headers = new Dictionary<string, string>()
{
{ "Content-Type", "application/json" },
{ "X-Custom-Header", "I am Rico" }
},
Contents = c => c.Write(jsonBytes, 0, jsonBytes.Length)
};//Response.AsJson or Response.AsXml
};
忍不住說~~~Nancy好威
