ASP.net 核心如何映射 post 并将请求路由到 HTTP://site/area/controller

Question

我要映射我的 post 并向 URL http://site/area/controller 提出请求，我使用了 HttpPost 和 HttpPut 属性。

但是当我post数据到服务器时，它返回404 Not found。

我的代码：

public class ApplicationsController : Controller
{
    private readonly IApplicationService _applicationService;

    public ApplicationsController(IApplicationService applicationService)
    {
        _applicationService = applicationService;
    }

    [HttpGet]
    public async Task<IActionResult> Index(ApplicationQuery query)
    {
        var permissionNodes = await _applicationService.SelectePagedApplicationsAsync(query);
        ViewData["Query"] = query;
        return View(permissionNodes.Data);
    }

    [HttpPost("/Applications")]
    public async Task<IActionResult> Create(ApplicationViewModel model)
    {
        var app = Mapper.Map<Application>(model);
        var result = await _applicationService.CreateApplicationAsync(app);
        ViewData["ServiceResult"] = result;
        return View(nameof(Edit));
    }

    [HttpPut("/Applications")]
    public async Task<IActionResult> Update(ApplicationViewModel model)
    {
        var app = Mapper.Map<Application>(model);
        var result = await _applicationService.CreateApplicationAsync(app);
        ViewData["ServiceResult"] = result;
        return View(nameof(Edit));
    }

    [HttpGet]
    public async Task<IActionResult> Edit(long? id)
    {
        var result = await _applicationService.FindApplicationAsync(new ApplicationQuery
        {
            Id = id
        });
        var model = Mapper.Map<ApplicationViewModel>(result.Data);
        return View(model);
    }

让 MVC 将我的请求映射到我的操作的方法是什么？

您似乎缺少相关路由的令牌分配。

Token replacement in route templates ([controller], [action], [area])

For convenience, attribute routes support token replacement by enclosing a token in square-braces ([, ]). The tokens [action], [area], and [controller] will be replaced with the values of the action name, area name, and controller name from the action where the route is defined.

鉴于您希望将这些路由隔离到仅 POST 和 PUT 端点，因此相应地更新路由

public class ApplicationsController : Controller {

    //...code removed for brevity

    //Matches POST /{area}/applications
    [HttpPost("[area]/[controller]")]
    public async Task<IActionResult> Create([FromBody]ApplicationViewModel model) {
        //...code removed for brevity
    }

    //Matches PUT /{area}/applications
    [HttpPut("[area]/[controller]")]
    public async Task<IActionResult> Update([FromBody]ApplicationViewModel model) {
        //...code removed for brevity
    }

    //...code removed for brevity
}

以上还假设已经对区域进行了适当的配置
