OWIN.WebApi WebApi层
OWIN.WebApi.Sv WebApi服务层，将要作为启动项！
1 using System.Web.Http;
2 using System.Web.Http.Dispatcher;
3 using System;
4 using System.Collections.Concurrent;
5 using System.Collections.Generic;
6 using System.Linq;
7 using System.Net;
8 using System.Net.Http;
9 using System.Web.Http.Controllers;
10
11 namespace OWIN.WebApi.config
12 {
13 public class WebApiApplication : System.Web.HttpApplication
14 {
15 protected void Application_Start()
16 {
17 //ignore the xml return it`s setting let json return only
18 GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
19 GlobalConfiguration.Configuration.Formatters.Remove(GlobalConfiguration.Configuration.Formatters.XmlFormatter);
20
21 GlobalConfiguration.Configuration.Services.Replace(typeof(IHttpControllerSelector),
22 new WebApiControllerSelector(GlobalConfiguration.Configuration));
23 }
24 }
25 /// <summary>
26 /// the WebApiControllerSelector
27 /// author:qixiao
28 /// time:2017-1-31 19:24:32
29 /// </summary>
30 public class WebApiControllerSelector : DefaultHttpControllerSelector
31 {
32 private const string NamespaceRouteVariableName = "Namespace";
33 private readonly HttpConfiguration _configuration;
34 private readonly Lazy<ConcurrentDictionary<string, Type>> _apiControllerCache;
35
36 public WebApiControllerSelector(HttpConfiguration configuration)
37 : base(configuration)
38 {
39 _configuration = configuration;
40 _apiControllerCache = new Lazy<ConcurrentDictionary<string, Type>>(
41 new Func<ConcurrentDictionary<string, Type>>(InitializeApiControllerCache));
42 }
43
44 private ConcurrentDictionary<string, Type> InitializeApiControllerCache()
45 {
46 IAssembliesResolver assembliesResolver = this._configuration.Services.GetAssembliesResolver();
47 var types = this._configuration.Services.GetHttpControllerTypeResolver()
48 .GetControllerTypes(assembliesResolver).ToDictionary(t => t.FullName, t => t);
49
50 return new ConcurrentDictionary<string, Type>(types);
51 }
52
53 public IEnumerable<string> GetControllerFullName(HttpRequestMessage request, string controllerName)
54 {
55 object namespaceName;
56 var data = request.GetRouteData();
57 IEnumerable<string> keys = _apiControllerCache.Value.ToDictionary<KeyValuePair<string, Type>, string, Type>(t => t.Key,
58 t => t.Value, StringComparer.CurrentCultureIgnoreCase).Keys.ToList();
59
60 if (!data.Values.TryGetValue(NamespaceRouteVariableName, out namespaceName))
61 {
62 return from k in keys
63 where k.EndsWith(string.Format(".{0}{1}", controllerName,
64 DefaultHttpControllerSelector.ControllerSuffix), StringComparison.CurrentCultureIgnoreCase)
65 select k;
66 }
67
68 string[] namespaces = (string[])namespaceName;
69 return from n in namespaces
70 join k in keys on string.Format("{0}.{1}{2}", n, controllerName,
71 DefaultHttpControllerSelector.ControllerSuffix).ToLower() equals k.ToLower()
72 select k;
73 }
74
75 public override HttpControllerDescriptor SelectController(HttpRequestMessage request)
76 {
77 Type type;
78 if (request == null)
79 {
80 throw new ArgumentNullException("request");
81 }
82 string controllerName = this.GetControllerName(request);
83 if (string.IsNullOrEmpty(controllerName))
84 {
85 throw new HttpResponseException(request.CreateErrorResponse(HttpStatusCode.NotFound,
86 string.Format("No route providing a controller name was found to match request URI ‘{0}‘", new object[] { request.RequestUri })));
87 }
88 IEnumerable<string> fullNames = GetControllerFullName(request, controllerName);
89 if (fullNames.Count() == 0)
90 {
91 throw new HttpResponseException(request.CreateErrorResponse(HttpStatusCode.NotFound,
92 string.Format("No route providing a controller name was found to match request URI ‘{0}‘", new object[] { request.RequestUri })));
93 }
94
95 if (this._apiControllerCache.Value.TryGetValue(fullNames.First(), out type))
96 {
97 return new HttpControllerDescriptor(_configuration, controllerName, type);
98 }
99 throw new HttpResponseException(request.CreateErrorResponse(HttpStatusCode.NotFound,
100 string.Format("No route providing a controller name was found to match request URI ‘{0}‘", new object[] { request.RequestUri })));
101 }
102 }
103 }
4、在OWIN.WebApi.Srv层里面新建AppStart.cs类，并且写如下代码：
1 using Microsoft.Owin.Hosting;
2 using System;
3 using Owin;
4 using System.Web.Http;
5 using System.Web.Http.Dispatcher;
6 using QX_Frame.App.WebApi.Extends;
7 using System.Web.Http.Cors;
8
9 namespace OWIN.WebApi.Srv
10 {
11 class AppStart
12 {
13 static void Main(string[] args)
14 {
15 //string baseAddress = "http://localhost:3999/"; //localhost visit
16 string baseAddress = "http://+:3999/"; //all internet environment visit
17 try
18 {
19 WebApp.Start<StartUp>(url: baseAddress);
20 Console.WriteLine("BaseIpAddress is " + baseAddress);
21 Console.WriteLine("\nApplication Started !");
22 }
23 catch (Exception ex)
24 {
25 Console.WriteLine(ex.ToString());
26 }
27
28 for (;;)
29 {
30 Console.ReadLine();
31 }
32 }
33 }
34 //the start up configuration
35 class StartUp
36 {
37 public void Configuration(IAppBuilder appBuilder)
38 {
39 HttpConfiguration config = new HttpConfiguration();
40
41 // Web API configuration and services
42 //跨域配置 //need reference from nuget
43 config.EnableCors(new EnableCorsAttribute("*", "*", "*"));
44 //enabing attribute routing
45 config.MapHttpAttributeRoutes();
46 // Web API Convention-based routing.
47 config.Routes.MapHttpRoute(
48 name: "DefaultApi",
49 routeTemplate: "api/{controller}/{id}",
50 defaults: new { id = RouteParameter.Optional },
51 namespaces: new string[] { "OWIN.WebApi" }
52 );
53 config.Services.Replace(typeof(IHttpControllerSelector), new OWIN.WebApi.config.WebApiControllerSelector(config));
54
55 //if config the global filter input there need not write the attributes
56 //config.Filters.Add(new App.Web.Filters.ExceptionAttribute_DG());
57
58 //new ClassRegisters(); //register ioc menbers
59
60 appBuilder.UseWebApi(config);
61 }
62 }
63 }
里面对地址进行了配置，当然可以根据需求自行配置，显示信息也进行了适当的展示，需要说明的一点是，我这里进行了跨域的配置，没有配置或者是不需要的请注释掉并忽略！
这里需要注意的是第53行，这里引用的是刚才的OWIN.WebApi层的Global.cs里面的类，请对照上述两段代码进行查找。
1 using QX_Frame.App.WebApi;
2 using QX_Frame.Helper_DG;
3 using System.Web.Http;
4
5 namespace OWIN.WebApi
6 {
7 /*
8 * author:qixiao
9 * time:2017-2-27 10:32:57
10 **/
11 public class Test1Controller:ApiController
12 {
13 //access http://localhost:3999/api/Test1 get method
14 public IHttpActionResult GetTest()
15 {
16 //throw new Exception_DG("login id , pwd", "argumets can not be null", 11111, 2222);
17 return Json(new { IsSuccess = true, Msg = "this is get method" });
18 }
19 //access http://localhost:3999/api/Test1 post method
20 public IHttpActionResult PostTest(dynamic queryData)
21 {
22 return Json(new { IsSuccess = true, Msg = "this is post method",Data=queryData });
23 }
24 //access http://localhost:3999/api/Test1 put method
25 public IHttpActionResult PutTest()
26 {
27 return Json(new { IsSuccess = true, Msg = "this is put method" });
28 }
29 //access http://localhost:3999/api/Test1 delete method
30 public IHttpActionResult DeleteTest()
31 {
32 return Json(new { IsSuccess = true, Msg = "this is delete method" });
33 }
34 }
35 }
这里我是用的是RESTFull风格的WebApi控制器接口。
然后我们可以进行试运行：
服务启动成功！
测试通过，我们可以尽情地探索后续开发步骤！
OWIN 自宿主模式WebApi项目，WebApi层作为单独类库供OWIN调用
