aspnetboilerplate 递归实体查找内部 500 错误

Question

查询递归实体查找时出现以下错误。

错误:

{"message":"An error has occurred.","exceptionMessage":"There is an action GetCategories defined for api controller app/category but with a different HTTP Verb. Request verb is GET. It should be Post","exceptionType":"System.Web.HttpException","stackTrace":" at Abp.WebApi.Controllers.Dynamic.Selectors.AbpApiControllerActionSelector.GetActionDescriptorByActionName(HttpControllerContext controllerContext, DynamicApiControllerInfo controllerInfo, String actionName)\r\n at Abp.WebApi.Controllers.Dynamic.Selectors.AbpApiControllerActionSelector.SelectAction(HttpControllerContext controllerContext)\r\n at System.Web.Http.ApiController.ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken)\r\n at Castle.Proxies.DynamicApiController1Proxy_5.ExecuteAsync_callback(HttpControllerContext controllerContext, CancellationToken cancellationToken)\r\n at Castle.Proxies.Invocations.ApiController_ExecuteAsync_5.InvokeMethodOnTarget()\r\n at Castle.DynamicProxy.AbstractInvocation.Proceed()\r\n at Abp.WebApi.Controllers.Dynamic.Interceptors.AbpDynamicApiControllerInterceptor1.Intercept(IInvocation invocation)\r\n at Castle.DynamicProxy.AbstractInvocation.Proceed()\r\n at Castle.Proxies.DynamicApiController`1Proxy_5.ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken)\r\n at System.Web.Http.Dispatcher.HttpControllerDispatcher.d__1.MoveNext()"}

错误仅在我添加第一个具有 ParentId

的条目后发生

型号

     [Table("Categories")]
     public class Category : FullAuditedEntity
     {
        [Required]
        public string Name { get; set; }
        [Required]
        public string SharepointMapping { get; set; }
        public int? ParentId { get; set; }
        public Category Parent { get; set; }
       public List<Category> Children { get; set; }
     }

类别应用服务

  public ListResultDto<CategoryListDto> GetCategories(GetCategoriesInput input)
  {
    var categories = _categoryRepository
        .GetAll()
        .WhereIf(
            !input.Filter.IsNullOrEmpty(),
            p => p.Name.Contains(input.Filter) 
        )
        .OrderBy(p => p.Name)
        .ToList();

        return new ListResultDto<CategoryListDto>(categories.MapTo<List<CategoryListDto>>());
  }

CategoryListDto

[AutoMapFrom(typeof(Category))]
public class CategoryListDto : FullAuditedEntityDto
{
    public string Name { get; set; }
    public string SharepointMapping { get; set; }
    public int? ParentId { get; set; }
    public virtual Category Parent { get; set; }       
}

所有 WebApi 方法的默认 http-verb 是 POST。使用 POST.

提出您的请求

如果你不喜欢这个解决方案，你可以使用约定俗成的动词。对于常规动词，它会查找方法名称前缀并匹配相关的 http 动词。

GetCategories -> HTTP-GET
删除类别 -> HTTP-DELETE
更新类别 -> HTTP-PUT
创建类别 -> HTTP-POST

您可以使用 WithConventionalVerbs 方法，如下所示：

Configuration.Modules.AbpWebApi().DynamicApiControllerBuilder
    .ForAll<IApplicationService>(Assembly.GetAssembly(typeof(SimpleTaskSystemApplicationModule)), "tasksystem")
    .WithConventionalVerbs()
    .Build();
