我怎样才能得到ApiController的所有操作的列表 [英] How can I get the list of all actions of ApiController

问题描述

我试图用这个code，但它不工作（返回空列表）

  VAR controllerDescriptor =新ReflectedControllerDescriptor（控制器）;
ActionDescriptor [] =行动controllerDescriptor.GetCanonicalActions（）;
 

解决方案

摸索出如何获得ApiController方法签名，而不是控制。

 字符串项=;
        IEnumerable的＆LT;大会＆GT; 。组件= BuildManager.GetReferencedAssemblies（）演员LT;大会＆GT;（）;        的foreach（大会FoundAssembly的组件）
        {
            字符串的AssemblyName = FoundAssembly.FullName;
            IEnumerable的＆LT;＆所属类别GT;类型= FoundAssembly.DefinedTypes.Where（类型=＆GT;类型= NULL＆放大器;！＆安培; type.IsPublic和放大器;＆安培; type.IsClass和放大器;＆安培;！type.IsAbstract和放大器;＆安培; typeof运算（ApiController）.IsAssignableFrom（类型））;
            的foreach（所属类别ControllerType的类型）
            {
                System.Web.Http.Controllers.ApiControllerActionSelector ApiControllerSelection =新System.Web.Http.Controllers.ApiControllerActionSelector（）;
                System.Web.Http.Controllers.HttpControllerDescriptor ApiDescriptor =新System.Web.Http.Controllers.HttpControllerDescriptor（新System.Web.Http.HttpConfiguration（），ControllerType.Name，ControllerType）;
                ILookup＆LT;字符串，System.Web.Http.Controllers.HttpActionDescriptor＆GT; ApiMappings = ApiControllerSelection.GetActionMapping（ApiDescriptor）;                的foreach（VAR地图在ApiMappings）
                {
                    的foreach（在地图System.Web.Http.Controllers.HttpActionDescriptor操作）
                    {
                        项目+ =[控制器=+ ControllerType.Name +行动=+（（System.Web.Http.Controllers.ReflectedHttpActionDescriptor）（动作））的MethodInfo +];
                    }
                }
            }
        }
 

输出：

  [控制器= CarController行动= System.Net.Http.Htt presponseMessage登录（）]
[控制器= CarController行动=虚空MyCustomGet（）]
[控制器= CarController行动=虚空MyCustomPost（）]
[控制器= GenericControllerApi行动= System.Net.Http.Htt presponseMessage登录（）]
[控制器= Values​​Controller行动= System.String获取（）]
[控制器= Values​​Controller行动= System.String获取（Int32）已]
[控制器= Values​​Controller行动=虚空邮政（System.String）
[控制器= Values​​Controller行动=虚空认沽（的Int32，System.String）
[控制器= Values​​Controller行动=虚空删除（Int32）已]
[控制器= ODataMetadataController行动= Microsoft.Data.Edm.IEdmModel的getMetaData（）]
[控制器= ODataMetadataController行动= Microsoft.Data.OData.ODataWorkspace GetServiceDocument（）]
 

有一个额外的控制器ODataMetadataController我没有创造。由最初的创建项目可能增加。我还没有看过，看是否可以简化。

I tried to use this code, but it does not work (return empty list)

var controllerDescriptor = new ReflectedControllerDescriptor(controller);
ActionDescriptor[] actions = controllerDescriptor.GetCanonicalActions();

解决方案

Worked out how to get the ApiController method signatures instead of Controller.

        string Items = "";
        IEnumerable<Assembly> Assemblies = BuildManager.GetReferencedAssemblies().Cast<Assembly>();

        foreach (Assembly FoundAssembly in Assemblies)
        {
            string AssemblyName = FoundAssembly.FullName;
            IEnumerable<TypeInfo> Types = FoundAssembly.DefinedTypes.Where(type => type != null && type.IsPublic && type.IsClass && !type.IsAbstract && typeof(ApiController).IsAssignableFrom(type));
            foreach (TypeInfo ControllerType in Types)
            {
                System.Web.Http.Controllers.ApiControllerActionSelector ApiControllerSelection = new System.Web.Http.Controllers.ApiControllerActionSelector();
                System.Web.Http.Controllers.HttpControllerDescriptor ApiDescriptor = new System.Web.Http.Controllers.HttpControllerDescriptor(new System.Web.Http.HttpConfiguration(), ControllerType.Name, ControllerType);
                ILookup<string, System.Web.Http.Controllers.HttpActionDescriptor> ApiMappings = ApiControllerSelection.GetActionMapping(ApiDescriptor);

                foreach (var Maps in ApiMappings)
                {
                    foreach (System.Web.Http.Controllers.HttpActionDescriptor Actions in Maps)
                    {
                        Items += "[ controller=" + ControllerType.Name + " action=" + ((System.Web.Http.Controllers.ReflectedHttpActionDescriptor)(Actions)).MethodInfo + "]";
                    }
                }
            }
        }

Output:

[ controller=CarController action=System.Net.Http.HttpResponseMessage Login()]
[ controller=CarController action=Void MyCustomGet()]
[ controller=CarController action=Void MyCustomPost()]
[ controller=GenericControllerApi action=System.Net.Http.HttpResponseMessage Login()]
[ controller=ValuesController action=System.String Get()]
[ controller=ValuesController action=System.String Get(Int32)]
[ controller=ValuesController action=Void Post(System.String)]
[ controller=ValuesController action=Void Put(Int32, System.String)]
[ controller=ValuesController action=Void Delete(Int32)]
[ controller=ODataMetadataController action=Microsoft.Data.Edm.IEdmModel GetMetadata()]
[ controller=ODataMetadataController action=Microsoft.Data.OData.ODataWorkspace GetServiceDocument()]

There is an extra controller "ODataMetadataController" that I did not create. Possibly added by the initial project creation. I also have not looked to see if this could be simplified.
