如何在ASP.NET Web API 2中更改已分配的路由

Question

请指出正确的问题，如果这是重复的。 我还没有找到可以解决我所表达内容的方法。

所以我有一个具有两条相同路线的控制器

// GET: api/UserPwordHints/5
[ResponseType(typeof(UserPwordHintsModels))]
public async Task<IHttpActionResult> GetUserPwordHintsModels(string id)

// PUT: api/UserPwordHints/5
[ResponseType(typeof(void))]
public async Task<IHttpActionResult> PutUserPwordHintsModels(string id, 
UserPwordHintsModels userPwordHintsModels)

唯一的区别是HTTP方法。 现在当我使用路线时，第二条路线称为

  // PUT: api/UserPwordHints/5

我的WebConfig.cs看起来像这样

config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

这是默认值。 通过对SO的搜索，我知道我添加了一个代码，该代码明确指示要使用的代码。 但是，它们都有相同的路线。 分辨使用哪种确切方法的最佳方法是什么？

编辑：使用GET方法仍会调用PUT方法并出现错误

cannot send a content-body with this verb-type post

EDIT2调用方法

GET_METHOD = "GET"
SendWebRequest(getPassWordHintURL, requestBody:=body, httpMethod:=GET_METHOD)


Private Function SendWebRequest(
                   requestUrl As String,
                   Optional requestBody As String = Nothing,
                   Optional httpMethod As String = "POST",
                   Optional bearerToken As String = Nothing) As String

        Dim responseFromServer

        httpReq = WebRequest.Create(requestUrl)
        httpReq.Proxy = Nothing
        httpReq.Method = httpMethod
        httpReq.ContentType = "application/json"

        If bearerToken IsNot Nothing Then
            httpReq.Headers.Add(HttpRequestHeader.Authorization, "Bearer " + bearerToken)
        End If

        httpReq.ContentLength = 0

        If requestBody IsNot Nothing Then
            Dim dataBytes = Encoding.UTF8.GetBytes(requestBody)
            httpReq.ContentLength = dataBytes.Length
            Dim stream = httpReq.GetRequestStream()
            stream.Write(dataBytes, 0, dataBytes.Length)
            stream.Close()
        End If

        Dim resp As WebResponse
        Try
            resp = httpReq.GetResponse()
            Dim dataStream = resp.GetResponseStream()
            Dim reader = New StreamReader(dataStream)
            ' Read the content.
            responseFromServer = reader.ReadToEnd()

            dataStream.Close()
        Catch ex As WebException
            Throw ex
        End Try

        Return responseFromServer
    End Function

为这两种方法定义的路由相同，但是方法的类型不同无需更改默认路由。

如果要调用GetUserPwordHintsModels() ，请使用route作为

   // GET: api/UserPwordHints/5
       ^^^^ See the difference

如果要调用PutUserPwordHintsModels() ，请使用route作为

 // PUT: api/UserPwordHints/5
    ^^^^ PUT and GET

您可以使用HTTPPut和HTTPGet批注装饰方法。 如同

// GET: api/UserPwordHints/5
[ResponseType(typeof(UserPwordHintsModels)), HTTPGet]
public async Task<IHttpActionResult> GetUserPwordHintsModels(string id)

// PUT: api/UserPwordHints/5
[ResponseType(typeof(void)), HTTPPut]
public async Task<IHttpActionResult> PutUserPwordHintsModels(string id, 
UserPwordHintsModels userPwordHintsModels)
