How to use more than one parameter for HttpGet (MVC/WebAPI)

I need to change my WebApi (asp.net Core) controller to add one special GET action that accepts more than 1 parameter. Instead of the regular stuff:
        
        [HttpGet("{id}")]
        public string Get(int id)
        {
            //var result = rep.GetAccount(id);
            return "Regular way hit";
        }

Open in new window


I need to send in multiple parameters or a dto containing those parameters. So basically something like this:
        
[HttpGet("{dto}")]
        public string Get(AccountDTO dto)
        {
            //var result = rep.GetAccount(dto.AccountNumber, dto.AccountName, dto.BrokerName, dto.Symbol);
            return "Hit it";
        }

Open in new window


I can't figure out if this should be done by adding attributes to the HttpGet, or if I need a special route (and if so how to do that).

TIA!

Add the FromUri attribute to your parameter.

Hi! I tried that, but I'm unable to separate the different GET methods, unless I create a completely new route. So if I use any sort of parameterized call, It's always caught by this function:
http://localhost:5000/api/accounts/find/?AccountID=0&AccountNumber=123456&AccountName=DEV&BrokerNameTest%20broker&Symbol=GBPUSD

        [HttpGet("{accountid}")]
        public string Get(int AccountID)
        {
            var result = rep.GetAccountByID(AccountID);
            return "Hit single function";
        }

Open in new window

Even though the URL has "find" in it I never reach the intended action:
        [HttpGet("{dto}")]
        public string Find([FromUri]AccountDTO dto)
        {
            //var result = rep.GetAccount(dto.AccountID, dto.AccountNumber, dto.AccountName, dto.BrokerName, dto.Symbol);
            return "Hit dto function";
        }

Open in new window


If I add a completely new route I can make it work like this:
        [Route("[action]/{accountnumber}/{accountname}/{brokername}/{symbol}")]
        [HttpGet]
        public string Check(int AccountNumber, string AccountName, string BrokerName, string Symbol)
        {
            //http://localhost:5000/api/accounts/check/123456/DEV/Test%20broker/GBPUSD
            var result = rep.CheckAccount(AccountNumber, AccountName, BrokerName, Symbol);
            return "Hit Check function";
        }

This just looks all wrong to me.

I got one step further, by adding the route to my find function, I can finally reach both methods:
        [Route("[action]/{dto}")]
        [HttpGet("{dto}")]
        public string Find(int id, [FromUri]AccountDTO dto)
        {
            //var result = rep.GetAccount(dto.AccountID, dto.AccountNumber, dto.AccountName, dto.BrokerName, dto.Symbol);
            return "Hit dto function";
        }

        [HttpGet("{accountid}")]
        public string Get(int AccountID)
        {
            var result = rep.GetAccountByID(AccountID);
            return "Hit single function";
        }

Open in new window

http://localhost:5000/api/accounts/1 hits Get()
http://localhost:5000/api/accounts/find/1 hits Find()

Find can't translate the variables into a dto, but that probably only means I need to build a client that translates the dto into proper json. Can that be tested with Fiddler or Postman?

Ah, using Route instead of HttpGet. I knew there was a simple solution that I was forgetting. Thanks!
