HttpGet Action不会被调用

Question

Startup.cs,锅炉板:

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

我有一个控制器类,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
    }
}

基本上我试图添加一个方法,Authenticate我拿a username和password.我设置了一个路由和一些HTTPGet参数.但无论我多么惹它(前往http://localhost:64880/api/members/authenticate/,作为一个例子),我无法得到我添加的Authenticate方法来调用.

我想这是一个路由的事情？

Answer 1

你正在混合路线.

假设您将控制器装饰[Route("api/Members")]为路径前缀,然后将操作装饰为[Route("api/members/authenticate/")],则该操作的结果路径将是api/Members/api/members/authenticate/.看看你试图打电话的区别？

通常,您希望对身份验证操作执行POST,以便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.您似乎正在使用属性路由,还混合了路由属性和http谓词属性的路由模板.

此外,这[Produces("application/json")]完全没有意义,因为JSON是默认值

[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();
    }

}
