C# 使用RouteAttribute时无法提交表单，提交操作错误

以下是我的控制器操作：

HttpGet

// GET: ControllerName/Create
[Route("CreateDocument/{personId}")]
public ActionResult Create(int personId)
{
    var personDocumentation = new PersonDocumentation()
    {
        PersonId = pilotId
    };
    ViewBag.DocumentationTypeIdSelection = new SelectList(db.DocumentationTypes, "Id", "DocumentationTypeName");

    return View(personDocumentation);
}

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "Id,PersonId,DateReceived,DocumentationTypeId,Filepath")] PersonDocumentation personDocumentation)
{
    if (ModelState.IsValid)
    {
        if (Request.Files.Count > 0)
        {
            // performing stuff here
        }

        db.PersonDocumentations.Add(personDocumentation);
        db.SaveChanges();
        return RedirectToAction("Index", "PersonDocumentations", new {pilotId = personDocumentation.PilotId});
    }

    ViewBag.DocumentationTypeId = new SelectList(db.DocumentationTypes, "Id", "DocumentationTypeName", personDocumentation.DocumentationTypeId);
    return View(personDocumentation);
}

HttpPost

// GET: ControllerName/Create
[Route("CreateDocument/{personId}")]
public ActionResult Create(int personId)
{
    var personDocumentation = new PersonDocumentation()
    {
        PersonId = pilotId
    };
    ViewBag.DocumentationTypeIdSelection = new SelectList(db.DocumentationTypes, "Id", "DocumentationTypeName");

    return View(personDocumentation);
}

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "Id,PersonId,DateReceived,DocumentationTypeId,Filepath")] PersonDocumentation personDocumentation)
{
    if (ModelState.IsValid)
    {
        if (Request.Files.Count > 0)
        {
            // performing stuff here
        }

        db.PersonDocumentations.Add(personDocumentation);
        db.SaveChanges();
        return RedirectToAction("Index", "PersonDocumentations", new {pilotId = personDocumentation.PilotId});
    }

    ViewBag.DocumentationTypeId = new SelectList(db.DocumentationTypes, "Id", "DocumentationTypeName", personDocumentation.DocumentationTypeId);
    return View(personDocumentation);
}

查看/表单

@using (Html.BeginForm("Create", "PersonDocumentations", FormMethod.Post, new {enctype = "multipart/form-data" }))
{
    // Form stuff here

    <div class="form-group">
        <input type="submit" value="Create" class="btn btn-lg btn-success" />
    </div>
}

在我的查看页面上。。要获取HttpGet操作，我有一个按钮链接：

@Html.ActionLink("Create New Documentation", "Create", new {personId = Model.PersonId}, new {@class = "btn btn-info"})

但是，当我将鼠标悬停在按钮上时，我会看到左下角的链接：

http://localhost:xxxxx/CreateDocument?personId=4

这不应该是：

http://localhost:xxxxx/CreateDocument/4

当我从HttpPost操作中删除Route属性时，左下角的url显示为

http://localhost:xxxxx/CreateDocument/4

然后，当我点击按钮时，我收到404个错误：

Requested Url:  /CreateDocument


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

        routes.MapMvcAttributeRoutes();

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

您正在混合基于属性和约定的路由

如果在控制器上使用属性路由，则需要全力以赴。当使用多个动作时，还必须包括

[Http{Verb}]

，以进一步区分动作路由

public class PersonDocumentationsController : Controller {

    [HttpGet]
    public ActionResult Index() {
        //...
    }

    //GET CreateDocument/4
    [HttpGet]
    [Route("CreateDocument/{personId:int}")]
    public ActionResult Create(int personId) {
        //...
    }

    //POST CreateDocument/4
    [HttpPost]
    [Route("CreateDocument/{personId:int}")]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "Id,PersonId,DateReceived,DocumentationTypeId,Filepath")] PersonDocumentation personDocumentation) {
        //...
    }
}

这还假设没有

RoutePrefix

应用于控制器

所以现在你打电话的时候

@Html.BeginForm("Create", "PersonDocumentations", FormMethod.Post, new {enctype = "multipart/form-data" }))

在

PersonDocumentationsController.Create

视图中，它将映射到正确的操作

POST-CreateDocument/4

对于操作链接，还需要包括所需的控制器

@Html.ActionLink("Create New Documentation", "Create", "PersonDocumentations" , new {personId = Model.PersonId}, new {@class = "btn btn-info"})

应该映射到哪个

GEThttp://localhost:xxxxx/CreateDocument/4

参考

浏览器的网络是怎么说的，您实际发送了哪个HTTP方法？它说的是POST，但当我调试时，我会转到HttpGet

POST/CreateDocument/4

您是否尝试添加[HttpGet]动词以获取操作并查看？@user9405863我有，但随后它导致404个错误，说找不到

CreateDocument/4
