Get route information on controller

In my response model, I have stuff like method and path of the route. Is there any classes or methods I can call to inject that into the function? Example

class FooController : ControllerBase {
  [HttpGet] // I know it's a get here, but not during runtime
  async Task<ActionResult<CoolioResponse>> Bar(
    // What to inject here? HttpContext?
  ) {
    
  }
}

class FooController : ControllerBase {
  [HttpGet] // I know it's a get here, but not during runtime
  async Task<ActionResult<CoolioResponse>> Bar(
    // What to inject here? HttpContext?
  ) {
    
  }
}

Not sure what you mean The method will be GET, as the attribute says The path will be what you define there

Sun「無用」OP•3mo ago

yes, but it's not in the code, I can't use it as a variable or return it to the user

Pobiega•3mo ago

yeah just look at HttpContext you dont need to inject it, its a property on the controllerbase

Sun「無用」OP•3mo ago

async Task<ActionResult<CoolioResponse>> Bar(
    // What to inject here? HttpContext?
) {
  return new CoolioResponse
  {
    Path = ??,
    Method = ??,
  };
}

async Task<ActionResult<CoolioResponse>> Bar(
    // What to inject here? HttpContext?
) {
  return new CoolioResponse
  {
    Path = ??,
    Method = ??,
  };
}

Like that

U can use nameof()

Angius•3mo ago

If that's the data you need to return nameof gets you the name of... the thing Does not give you the path So, no, you can't use nameof There's the UrlHelper class that has an .Action method, IIRC You give it the controller, the action method name, and it produces the path

I'm lost here, lol

Angius•3mo ago

I'm as lost as you, trying to figure out why you'd want to return "yes, this is a GET endpoint with a path of /foo/bar" from an endpoint handling a GET method at the path /foo/bar It's kinda obvious that calling GET /foo/bar will be... the GET method and the /foo/bar path

Sun「無用」OP•3mo ago

bc I just want the info, most users are kinda dumb :d

Angius•3mo ago

I've no clue why you'd want it

Pobiega•3mo ago

its all in HttpContext

Angius•3mo ago

It's like sending an email to [email protected] and getting a reply "you sent an email to [email protected]"

Sun「無用」OP•3mo ago

also I'm gonna do stuff like

[HttpPut]
[HttpPatch]
async Task meh ....

[HttpPut]
[HttpPatch]
async Task meh ....

Angius•3mo ago

Still, the user knows what they called If they called client.PostAsJsonAsync() they called a POST method No need to tell them "ah, yes, this was indeed a post request"

Sun「無用」OP•3mo ago

also I like problem response and it has it there :d

Angius•3mo ago

ProblemDetails does not return a request method

Sun「無用」OP•3mo ago

ProblemDetails doesn't work properly for me and it just looks incomplete, so I just did a

public record struct ProblemResponse<T>(
    HttpStatusCode StatusCode,
    string Title,
    string Method,
    string Path,
    T? Data,
    ApplicationError[] Errors
);

public record struct ProblemResponse<T>(
    HttpStatusCode StatusCode,
    string Title,
    string Method,
    string Path,
    T? Data,
    ApplicationError[] Errors
);

Status code that gets returned is the status code that gets returned...? Why even include that The method of the request is the method of the request

Pobiega•3mo ago

[HttpGet("anon")]
public ActionResult<MyHttpDto> AnonymousEndpoint()
{
    var method = HttpContext.Request.Method;
    var path = HttpContext.Request.Path.ToString();

    return new MyHttpDto(method, path);
}

[HttpGet("anon")]
public ActionResult<MyHttpDto> AnonymousEndpoint()
{
    var method = HttpContext.Request.Method;
    var path = HttpContext.Request.Path.ToString();

    return new MyHttpDto(method, path);
}

https://localhost:7089/test/anon

{
  "method": "GET",
  "path": "/test/anon"
}

{
  "method": "GET",
  "path": "/test/anon"
}

Sun「無用」OP•3mo ago

I've seen way too much code with people checking for status in the json, so I just do that by default now, lol

Angius•3mo ago

You call GET /foo/bar, get a 401 response with an error that says "you called /foo/bar with GET method and got a 401"

Pobiega•3mo ago

its all right there.

Angius•3mo ago

Makes zero sense to me No need to cater to half-brained bumbling idiots Fuck them seven ways to sunday and tell them to learn how to do shit properly I never cared about the 20 IQ Cro-Magnons trying to use my shit I recommend you don't either It's easier and more sane this way

Sun「無用」OP•3mo ago

thx

Angius•3mo ago

If they get a response with HTTP status code 403 and then wonder "uhhhh ugg got 503 but what the status code, ugg no get this" that's their problem

Sun「無用」OP•3mo ago

also btw, status is a property in the Problem RFC

Angius•3mo ago

I guess it does cater to the forementioned underdeveloped amoeabs, then Even it doesn't contain the request method and path, though

Sun「無用」OP•3mo ago

It has instance, which could be just the full path

Angius•3mo ago

Still not the method at least

Sun「無用」OP•3mo ago

welp, if I'm giving the status/path, then I should prolly complete the info, lol
