Question

我试图指出我的行动，基本上我有一个控制器有不同的方法，我想指向不同的方法，当我有一个名为create的方法时，一切运行良好，现在我有一个叫{{1从现在开始忽略最佳实践REST。因此，每当我需要指向createDocument它失败时，我就会得到这个（邮差）。

createDocument

我只是在我的控制器中有这个：

{
    "Message": "An error has occurred.",
    "ExceptionMessage": "Multiple actions were found that match the request: \r\nCreate on type server.Controllers.DocumentController\r\nCreateDocument on type server.Controllers.DocumentController",
    "ExceptionType": "System.InvalidOperationException",
    "StackTrace": "   at System.Web.Http.Controllers.ApiControllerActionSelector.ActionSelectorCacheItem.SelectAction(HttpControllerContext controllerContext)\r\n   at System.Web.Http.Controllers.ApiControllerActionSelector.SelectAction(HttpControllerContext controllerContext)\r\n   at System.Web.Http.ApiController.ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken)\r\n   at System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__1.MoveNext()"
}

它没有进入我试图调试它的控制器，我工作得很好的另一种方法输入没有问题。

public async Task<IHttpActionResult> CreateDocument([FromBody]List<DocumentDetails> details)
{
    return Ok(200);
}

我的路线配置如下：

public async Task<IHttpActionResult> Create([FromBody]AppDocument document)
        {

我怀疑它与我收到的参数有关，我收到了这样的jsonArray：

namespace server
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { action = "Index", id = UrlParameter.Optional }
            );
        }
    }
}

为此，我创建了2个模型，第一个具有简单列表

[
  {
    "key": "Table",
    "rows": 1,
    "cols": 1,
    "cells": 1
  },
  {
    "key": "Paragraph",
    "text": "asda",
    "fontSize": 14
  },
  {
    "key": "Paragraph",
    "text": "asda",
    "fontSize": 14
  },
  {
    "key": "Paragraph",
    "text": "asda",
    "fontSize": 14
  }
]

在列表元素中包含可能道具的第二个

namespace server.Models
{
    public class DocumentDetails
    {
        public int Id { get; set; }
        public List<DocumentAtributes> atributes { set; get; }
    }
}

更新WebApiConfig路由模板以识别路由模板中的操作名称，因为基于默认约定的路由模板通常为api/{controller}/{id}

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Attribute routing.
        config.MapHttpAttributeRoutes();

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

您还应该使用[HttpPost]属性更新操作。

public class DocumentController : ApiController {

    [HttpPost]
    public async Task<IHttpActionResult> CreateDocument([FromBody]List<DocumentDetails> details) {
        //...
    }

    [HttpPost]
    public async Task<IHttpActionResult> Create([FromBody]AppDocument document) {
        //...
    }
}

问题可能出在您调用api的js代码中。我相信你应该声明一个方法应该如何接收请求。

示例：

[HttpPost]
public async Task<IHttpActionResult> CreateDocument([FromBody]List<DocumentDetails> details)
{
    return Ok();
}

添加HttpPost属性使CreateDocument方法仅接收发布请求。
