如何将Web API添加到现有的ASP。NET MVC 4 Web应用程序项目?

我想增加一个ASP。NET Web API到ASP。NET MVC 4 Web应用程序项目，在Visual Studio 2012开发。我必须执行哪些步骤才能将功能正常的Web API添加到项目中?我知道我需要一个从ApiController派生的控制器，但这就是我所知道的全部。

如果我需要提供更多细节，请告诉我。

Open NuGet Package manager console and run PM> Install-Package Microsoft.AspNet.WebApi Add references to System.Web.Routing, System.Web.Net and System.Net.Http dlls if not there already Add the following class public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Web API routes config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); } } Add Application_Start method if not there already (in global.asax.cs file) protected void Application_Start() { //this should be line #1 in this method GlobalConfiguration.Configure(WebApiConfig.Register); } Right click controllers folder > add new item > web > Add Web API controller namespace <Your.NameSpace.Here> { public class VSController : ApiController { // GET api/<controller> : url to use => api/vs public string Get() { return "Hi from web api controller"; } } }

你可以从nuget安装如下图所示:

或者，在包管理器控制台中运行以下命令行:

Install-Package Microsoft.AspNet.WebApi

上述解决方案非常有效。如下图所示，我在选择项目模板时更倾向于选择Web API选项

注意:该解决方案适用于Visual Studio 2013或更高版本。最初的问题是在2012年提出的，现在是2016年，因此增加了Visual Studio 2013或更高版本的解决方案。

我也有同样的问题，解决方法很简单

右击soltion 安装Microsoft.ASP.NET.WebApi从“管理Nuget包Sulotion”

就是这样;)

在我的MVC 5项目中添加WebAPI。

Open NuGet Package manager console and run PM> Install-Package Microsoft.AspNet.WebApi Add references to System.Web.Routing, System.Web.Net and System.Net.Http dlls if not there already Right click controllers folder > add new item > web > Add Web API controller Web.config will be modified accordingly by VS Add Application_Start method if not there already protected void Application_Start() { //this should be line #1 in this method GlobalConfiguration.Configure(WebApiConfig.Register); } Add the following class (I added in global.asax.cs file) public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Web API routes config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); } } Modify web api method accordingly namespace <Your.NameSpace.Here> { public class VSController : ApiController { // GET api/<controller> : url to use => api/vs public string Get() { return "Hi from web api controller"; } // GET api/<controller>/5 : url to use => api/vs/5 public string Get(int id) { return (id + 1).ToString(); } } } Rebuild and test Build a simple html page <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script src="../<path_to_jquery>/jquery-1.9.1.min.js"></script> <script type="text/javascript"> var uri = '/api/vs'; $(document).ready(function () { $.getJSON(uri) .done(function (data) { alert('got: ' + data); }); $.ajax({ url: '/api/vs/5', async: true, success: function (data) { alert('seccess1'); var res = parseInt(data); alert('got res=' + res); } }); }); </script> </head> <body> .... </body> </html>
