HttpGet 操作不会被调用

Question

Startup.cs，样板：

app.UseMvc(routes =>
{
    routes.MapRoute(
        name: "default",
        template: "{controller=Home}/{action=Index}/{id?}");
});

我有一个控制器 class，MembersController。

[Produces("application/json")]
[Route("api/Members")]
public class MembersController : Controller
{
    [HttpGet("{email},{password}")]
    [Route("api/members/authenticate/")]
    public async void Authenticate(String email, String password)
    {
        ///the method that won't fire
    }


    // GET: api/Members/5
    [HttpGet("{id}")]
    public async Task<IActionResult> GetMember([FromRoute] int id)
    {
        ///the boiler plate method that gets called
    }
}

基本上我尝试添加一个方法，Authenticate，我在其中使用 username 和 password。我设置了一个路由和一些 HTTPGet 参数。但无论我如何处理它（例如前往 http://localhost:64880/api/members/authenticate/ ），我都无法调用添加的 Authenticate 方法。

我想这是一个路由的东西？

Answer 1

您正在混合路线。

鉴于您已将控制器装饰为 [Route("api/Members")] 作为路由前缀，然后将操作装饰为 [Route("api/members/authenticate/")]，该操作的最终路由将是 api/Members/api/members/authenticate/。看到您尝试调用的内容有何不同？

通常您会希望为身份验证操作执行 POST 以允许将参数发送到请求正文中的操作。

创建一个模型来保存数据

public class AuthModel {
    public string email { get; set; }
    public string password { get; set; }
}

接下来修复路线。您似乎在使用属性路由，还混合了路由属性和 http 动词属性的路由模板。

Also, that [Produces("application/json")] is completely pointless since JSON is the default

[Route("api/Members")]
public class MembersController : Controller {

    //Matches POST api/members/authenticate
    [HttpPost("authenticate")]
    public async Task<IActionResult> Authenticate([FromBody] AuthModel model) {
        String email = model.email;
        String password = model.password

        //fake async task
        await Task.Delay(1);

        return Ok();
    }

    // GET: api/Members/5
    [HttpGet("{id}")]
    public async Task<IActionResult> GetMember([FromRoute] int id) {
        ///the boiler plate method that gets called

        //fake async task
        await Task.Delay(1);

        return Ok();
    }

}
