Question

As my title already explains I am building a small Twitter Clone for a school project and while i want to go to someones profile page if i click on the poster name.

<a asp-area="" asp-controller="Home" asp-action="Profile">@userController.GetUser(post.UserId).DisplayName</a><a asp-area="" asp-controller="Home" asp-action="Profile">@userController.GetUser(post.UserId).DisplayName</a>

This only gets me so far that i can get the logged in username id via url and looking at it's own profile. well nice but i need to be able to get to other profiles aswell

I've also tried this

<a asp-area="" asp-controller="Home" asp-action="Profile" asp-route-userId="@post.UserId">@userController.GetUser(post.UserId).DisplayName</a>

But everytime i do that my url routing is off it will be like this:

Profile/3c126298-32f8-471e-8597-69c71c333df8?userId=f5c01788-97d9-4426-881a-53469e8c44f8

And it immediatly errors ofcourse.

Does anybody know how I can resolve this issue because i've tried searching for it on the Interwebz but i dont know how to fomulate the question so im not getting any results

Controller code:

        [Route("Profile/{id}")]
        public IActionResult Profile(string userId)
        {
            return View(userId);
        }

Answer 1

问题是您的路线参数名称和操作参数名称不一致。您的路线中有{id}，但动作签名中还有userId。它们应命名相同。从技术上讲，如果您指定的是asp-route-id，而不是asp-route-userId，则路由是正确的：

<a asp-area="" asp-controller="Home" asp-action="Profile" asp-route-id="@post.UserId">@userController.GetUser(post.UserId).DisplayName</a>

这将为您提供一个网址，例如：

Profile/f5c01788-97d9-4426-881a-53469e8c44f8

但是，由于参数名称未对齐，因此userId将为空。
