Question

编辑：PER Felipe的回答，我将webapiconfig中的代码更改为以下内容，并且效果很好 -

         config.Routes.MapHttpRoute( _
        name:="DefaultApi", _
        routeTemplate:="api/{controller}/{action}/{id}", _
        defaults:=New With {.id = RouteParameter.Optional} _
    )
    config.Routes.MapHttpRoute(name:="API Default", routeTemplate:="api/{controller}/{action}/{id}", defaults:=New With { _
.id = RouteParameter.[Optional] _

}）

我有一个带有4个功能的web api控制器 -

     <HttpGet> _
<ActionName("AllCerts")> _
Public Function GetCerts() As Object
    Dim LWCERTS As Array = objCert.GetCertificates
    Return LWCERTS
End Function


<HttpGet> _
<ActionName("MyCerts")> _
Public Function GetMyCert() As Object

    Dim lwMyCerts As Array = objCert.GetCertificates(Utilities.GetLogin())

    Return lwMyCerts

End Function

<HttpGet> _
<ActionName("GetValueDDA")> _
Public Function GetDDABanks()
    Dim objDDABankNum As New LucasEntities.Business.EF_DDA
    Dim lwDDABankNum As Array = objDDABankNum.GetDDABankJSON()

    Return lwDDABankNum

End Function
'' POST api/caapproval
<HttpPost> _
<ActionName("CertDtlsByID")> _
Public Function Post(value As CertDetailModel) As Object
    Dim objCertPosting As New LucasEntities.Business.EF_CertificatePosting
    Dim lwMyCertDetails As String = objCertPosting.GetBorrowingBaseAdvanceRequestJSON()

    Return lwMyCertDetails

End Function

在我的数据服务中，我有以下ajax调用 -

         var getallCertificates = function (CertificatesObservable) {
        var dataObservableArray = ko.observableArray([]);
        var newJ;
        $.ajax({
            type: "GET",
            dataType: "json",
            url: "/api/caapproval/AllCerts/",
            async: false,
            success: function (dataIn) {
                newJ = $.parseJSON(dataIn);

                CertificatesObservable([]);

                     dataIn.forEach(function (p) {
                        var certificate = new certificateModel(p.clientID, p.lwCertID, p.requestDate, p.userName, p.statusDescription, p.statusCode, p.statusDesc, p.ceoUserName, p.clientName, p.clientNumber, p.borrowBaseCount, p.advRequestCount, p.certType);
                        CertificatesObservable.push(certificate);
                    });
                    return CertificatesObservable(data);

            },
            error: function (error) {
                jsonValue = jQuery.parseJSON(error.responseText);
                //jError('An error has occurred while saving the new part source: ' + jsonValue, { TimeShown: 3000 });
            }

        });
        return CertificatesObservable(newJ);
    }

这是我的RouteConfig类 -

 Public Class RouteConfig
Public Shared Sub RegisterRoutes(ByVal routes As RouteCollection)
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}")


    routes.MapRoute( _
        name:="Default", _
        url:="{controller}/{action}/{id}", _
        defaults:=New With {.controller = "Home", .action = "Index", .id = UrlParameter.Optional} _
    )
End Sub

结束班

当我在控制器中放置断点时，我看到CertDtlsByID actionName下的Post函数始终运行，而不是AllCerts ActionName下的GetCerts。作为web api和路由的新手，我做错了什么导致总是调用“Post”方法？

当我直接在浏览器中运行网络API时，Chrome会显示以下错误 -

 Multiple actions were found that match the request: System.Object GetCerts() on type LucasNetApp.CAApprovalController System.Object GetMyCert() on type LucasNetApp.CAApprovalController System.Object GetDDABanks() on type LucasNetApp.CAApprovalController

在asp.net web api中，路由由WebApiConfig.cs文件夹上的App_Start文件控制。 ActionName属性不起作用，因为它是asp.net mvc的行为。

打开WebApiConfig.cs文件并尝试添加这些路由配置：

config.Routes.MapHttpRoute(name:="DefaultApiGet",
                           url:="api/{controller}",
                           defaults:=New With {.action = "Get"},
                           constraints:=new With {.httpMethod = new HttpMethodConstraint(HttpMethod.Get)})

config.Routes.MapHttpRoute(name:="DefaultApiWithAction",
                           url:="api/{controller}/{action}")

我不确定Vb.Net sintaxe，C#中的代码相同：

config.Routes.MapHttpRoute("DefaultApiGet",
                           "api/{controller}",
                           new {action = "Get"},
                           new {httpMethod = new HttpMethodConstraint(HttpMethod.Get)});

config.Routes.MapHttpRoute("DefaultApiWithAction",
                           "api/{controller}/{action}");

ajax调用总是在我的web api中使用相同的方法
