c# - ASP.NET Web API 操作路由不起作用

Question

我是 Web API 的新手，我知道 Web API 和 MVC 之间的区别之一是web API 使用HTTP 方法来选择按约定调用哪个方法。

Now I added an action parameter into my route, I think there's something went wrong to my knowledge, the route doesn't work.

这是我的 Controller ，主要问题是我只需要映射 SignIn 和 SignUp 方法。(其他 RestFul 方法工作正常。)

public class UsersController : ApiController
{
    private Model1Container db = new Model1Container();

    public IEnumerable<User> GetUsers()
    {
        return db.UserSet;
    }

    [HttpPost]
    public IHttpActionResult SignIn(string account, string password)
    {
        ...
    }

    [HttpPost]
    public IHttpActionResult SignUp(User user)
    {
        ...
    }

    public IHttpActionResult GetUser(int id)
    {
        ...
    }

    public IHttpActionResult PutUser(int id, User user)
    {
        ...
    }

    public IHttpActionResult DeleteUser(int id)
    {
        ...
    }

}

我什至尝试过为这两种方法在我的前两条路线上添加直接约束，

config.Routes.MapHttpRoute(
            name: "UsersSignIn",
            routeTemplate: "api/Users/SignIn",
            defaults: new { controller = "Users", action = "SignIn" }
        );

config.Routes.MapHttpRoute(
            name: "UsersSignUp",
            routeTemplate: "api/Users/SignUp",
            defaults: new { controller = "Users", action = "SignUp" }
        );

config.Routes.MapHttpRoute(
            name: "RestFulUser",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional },
            constraints: new { controller = "Users" }
        );

但结果是 [POST] "api/Users/SignUp" 和 "api/Users"可以映射到 SignUp 方法，但 "api/Users/SignIn" 总是不成功。

下面是关于我如何在 POSTMAN 中试用 API

请指出我错在哪里..

如果使用属性路由，您需要区分这两个路由。同样，一旦使用路由，它在 Controller 本身上就是全有或全无。您不能将它们与基于约定的路由混合使用。

[RoutePrefix("api/Users")]
public class UsersController : ApiController {
    private Model1Container db = new Model1Container();

    [HttpGet]
    [Route("")] //Matches GET api/Users
    public IEnumerable<User> GetUsers() {
        return db.UserSet;
    }

    [HttpPost]
    [Route("SignIn")] //Matches POST api/Users/SignIn
    public IHttpActionResult SignIn(string account, string password) {
        //...
    }

    [HttpPost]
    [Route("SignUp")] //Matches POST api/Users/SignUp
    public IHttpActionResult SignUp([FromBody]User user) {
        //...
    }

    [HttpGet]
    [Route("{id:int}")] //Matches GET api/Users/5
    public IHttpActionResult GetUser(int id) {
        //...
    }

    [HttpPut]
    [Route("{id:int}")] //Matches PUT api/Users/5
    public IHttpActionResult PutUser(int id,[FromBody]User user) {
        //...
    }

    [HttpDelete]
    [Route("{id:int}")] //Matches DELETE api/Users/5
    public IHttpActionResult DeleteUser(int id) {
        //...
    }
