为什么我的Web API调用返回[否行动控制器“DPlatypus”该请求＆QUOT匹配上找到;?

本文介绍了为什么我的Web API调用返回[否行动控制器“DPlatypus”该请求＆QUOT匹配上找到;?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我试图创建一个集成和使用DI与温莎城堡最简单可行的ASP.NET Web API的应用程序。

我有一个工作程序是比较复杂的，我曾尝试以裸露的骨头从复制（尽量少，仍然有它的工作）。

工作的应用程序有这个URL（主页）：

的http：//本地主机：28642 /

输入此：

的http：// shannon2：28642 / API /部门/计数

......在我的浏览器返回我想要的数据，从部门总监。

然而，新/简单/非工作应用程序有这个URL（主页）：

的http：//本地主机：33181 /

...并进入这样的：

的http：//本地主机：33181 / API / DPlatypus / 4

...不回我想要的数据：

其实，这样的：

`HTTP：// shannon2：33181 / API / DPlatypus / 4`

......返回：

的错误的请求 - 无效的主机名HTTP错误400请求主机名无效。的

虽然URI previously所示（的http：//本地主机：33181 / API / DPlatypus / 4 ）返回：

此XML文件没有出现与之相关联的任何样式信息。文档树如下所示。＆LT;错误＆GT;＆LT;消息＆GT;没有HTTP资源发现，请求URI`'匹配的http：//本地主机：33181 / API / DPlatypus / 4'.`＆LT; /信息＆GT;＆LT; MessageDetail＆GT;没有采取任何控制器DPlatypus与请求匹配上找到。＆LT; / MessageDetail＆GT;＆LT; /错误＆GT;＆LT; / MessageDetail＆GT;＆LT; /错误＆GT;

但我的做的有应匹配的要求，即一个动作：

公共类DPlatypusController：ApiController{    私人只读IDPlatypusRepository _duckbillRepository;    公共DPlatypusController（IDPlatypusRepository duckbillRepository）    {        如果（duckbillRepository == NULL）        {            抛出新的ArgumentNullException（duckbillRepository为空）;        }        _duckbillRepository = duckbillRepository;    }    [路线（API / DPlatypus）]    公共字符串GetDPlatypusNameById（INT标识）    {        返回_duckbillRepository.Get（ID）;    }}

下面是仓库类：

公共类DPlatypusRepository：IDPlatypusRepository{    私人列表＆LT; D​​Platypus＆GT; platypi =新的List＆LT; D​​Platypus＆GT;（）;    私人INT _nextID = 1;    公共DPlatypusRepository（）    {        加入（新DPlatypus {名称=唐纳德}）;        加入（新DPlatypus {名称=勾勾}）;        加入（新DPlatypus {名称=侯佩岑}）;        加入（新DPlatypus {名称=Platypup}）;        加入（新DPlatypus {名称=Platypop}）;        加入（新DPlatypus {名称=Platymop}）;        加入（新DPlatypus {名称=Platydude}）;        加入（新DPlatypus {名称=Platydudette}）;    }    公共IEnumerable的＆LT; D​​Platypus＆GT;得到所有（）    {        返回platypi;    }    公共字符串GET（INT ID）    {        返回platypi.Find（P =＆GT; p.Id == ID）.Name点;    }    公共DPlatypus添加（DPlatypus鸭嘴兽）    {        如果（鸭嘴兽== NULL）        {            抛出新的ArgumentNullException（鸭嘴兽）;        }        platypus.Id = _nextID ++;        platypi.Add（鸭嘴兽）;        返回鸭嘴兽;    }}

我注册/在WindsorDependencyResolver.cs安装，我已经改变的Global.asax和WebApiConfig.cs，使它们就像工作程序，但...没有去。为什么会这样呢？

更新

有关M. Mimpen，这里是Global.asax中：

命名空间WebApplication4{    公共类WebApiApplication：System.Web.HttpApplication    {        私有静态IWindsorContainer _container;        保护无效的Application_Start（）        {            ConfigureWindsor（GlobalConfiguration.Configuration）;            GlobalConfiguration.Configure（C =＆GT; WebApiConfig.Register（C，_container））;            FilterConfig.RegisterGlobalFilters（GlobalFilters.Filters）;            RouteConfig.RegisterRoutes（RouteTable.Routes）;            BundleConfig.RegisterBundles（BundleTable.Bundles）;        }        公共静态无效ConfigureWindsor（HttpConfiguration配置）        {            _container =新WindsorContainer（）;            _container.Install（FromAssembly.This（））;            _container.Kernel.Resolver.AddSubResolver（新CollectionResolver（_​​container.Kernel，真实））;            VAR dependencyResolver =新WindsorDependencyResolver（_​​container）;            configuration.DependencyResolver = dependencyResolver;        }        保护无效Application_End（）        {            _container.Dispose（）;            base.Dispose（）;        }    }}

更新2

有关基兰Challa;现在我得到：

此XML文件没有出现与之相关联的任何样式信息。文档树如下所示。＆LT;错误＆GT;＆LT;消息＆GT;没有HTTP资源发现，请求URI相匹配的http：//本地主机：33181 / API / DPlatypus ID = 4'。＆LT; /信息＆GT;＆LT; MessageDetail＆GT;没有采取任何控制器DPlatypus与请求匹配上找到。＆LT; / MessageDetail＆GT;＆LT; /错误＆GT;

解决方案

更改操作的路径模板类似下面另有值 ID 将被从查询字符串的预期。即的http：//本地主机：33181 / API / DPlatypus ID = 4 会工作。所以，你需要修改你的模板。

[路线（API / DPlatypus /（编号））公共字符串GetDPlatypusNameById（INT标识）

I am trying to create the simplest possible ASP.NET Web API app that incorporates and uses DI with Castle Windsor.

I have a working app that is more complicated, and I have tried to copy the "bare bones" from it (as little as possible and still have it work).

The working app has this URL ("Home Page"):

localhost:28642/

Entering this:

shannon2:28642/api/Departments/Count

...in my browser returns the data I want, from the Departments Controller.

However, the new/simple/non-working app has this URL ("Home Page"):

localhost:33181/

...and entering this:

localhost:33181/api/DPlatypus/4

...does NOT return the data I want:

In fact, this:

`shannon2:33181/api/DPlatypus/4`

...returns:

Bad Request - Invalid Hostname HTTP Error 400. The request hostname is invalid.

While the URI previously shown (localhost:33181/api/DPlatypus/4) returns:

This XML file does not appear to have any style information associated with it. The document tree is shown below. <Error> <Message> No HTTP resource was found that matches the request URI `'localhost:33181/api/DPlatypus/4'.` </Message> <MessageDetail> No action was found on the controller 'DPlatypus' that matches the request. </MessageDetail> </Error> </MessageDetail> </Error>

But I do have an action that should match the request, namely:

public class DPlatypusController : ApiController { private readonly IDPlatypusRepository _duckbillRepository; public DPlatypusController(IDPlatypusRepository duckbillRepository) { if (duckbillRepository == null) { throw new ArgumentNullException("duckbillRepository is null"); } _duckbillRepository = duckbillRepository; } [Route("api/DPlatypus")] public string GetDPlatypusNameById(int Id) { return _duckbillRepository.Get(Id); } }

Here is the Repository class:

public class DPlatypusRepository : IDPlatypusRepository { private List<DPlatypus> platypi = new List<DPlatypus>(); private int _nextId = 1; public DPlatypusRepository() { Add(new DPlatypus { Name = "Donald" }); Add(new DPlatypus { Name = "GoGo" }); Add(new DPlatypus { Name = "Patty" }); Add(new DPlatypus { Name = "Platypup" }); Add(new DPlatypus { Name = "Platypop" }); Add(new DPlatypus { Name = "Platymop" }); Add(new DPlatypus { Name = "Platydude" }); Add(new DPlatypus { Name = "Platydudette" }); } public IEnumerable<DPlatypus> GetAll() { return platypi; } public String Get(int id) { return platypi.Find(p => p.Id == id).Name; } public DPlatypus Add(DPlatypus platypus) { if (platypus == null) { throw new ArgumentNullException("platypus"); } platypus.Id = _nextId++; platypi.Add(platypus); return platypus; } }

I am registering/installing in WindsorDependencyResolver.cs, I have altered Global.asax, and WebApiConfig.cs, so that they are just like the working app, yet...no go. Why might this be?

UPDATE

For M. Mimpen, here is Global.asax:

namespace WebApplication4 { public class WebApiApplication : System.Web.HttpApplication { private static IWindsorContainer _container; protected void Application_Start() { ConfigureWindsor(GlobalConfiguration.Configuration); GlobalConfiguration.Configure(c => WebApiConfig.Register(c, _container)); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); } public static void ConfigureWindsor(HttpConfiguration configuration) { _container = new WindsorContainer(); _container.Install(FromAssembly.This()); _container.Kernel.Resolver.AddSubResolver(new CollectionResolver(_container.Kernel, true)); var dependencyResolver = new WindsorDependencyResolver(_container); configuration.DependencyResolver = dependencyResolver; } protected void Application_End() { _container.Dispose(); base.Dispose(); } } }

UPDATE 2

For Kiran Challa; now I get:

This XML file does not appear to have any style information associated with it. The document tree is shown below. <Error> <Message> No HTTP resource was found that matches the request URI 'localhost:33181/api/DPlatypus?id=4'. </Message> <MessageDetail> No action was found on the controller 'DPlatypus' that matches the request. </MessageDetail> </Error>

解决方案

Change your action's route template like the following otherwise the value id would be expected from the query string. i.e localhost:33181/api/DPlatypus?id=4 would work. So you need to modify your template.

[Route("api/DPlatypus/{id}")] public string GetDPlatypusNameById(int Id)
