I cannot figure out why I am getting a 404 for this request. I am pretty new to Web Api routing but I thought this was correct. Anyone have an idea of what the issue is. I have been on this for about an hour and a half. Thank you!
Routing Config:
public override void RegisterArea(AreaRegistrationContext context)
{
RouteTable.Routes.MapHttpRoute(
"japiClientOnboarding",
"japi/clientOnboarding/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
Controller Action:
[System.Web.Http.HttpPost]
public HttpResponseMessage createClientFromProspect(long prospectId)
{
........
}
My call via Postman:
Figured it out. Had to do with my parameter name not being "whitelisted" in our system. Very frustrating!

I can't reach any methods from my ApiController in anyway, the routing does appear if i try to reach it by a browser but no methods are shown.
My Controller:
namespace AgroRiego.Controllers
{
public class datacontrol : ApiController
{
[HttpGet, Route("api/get")]
public string Get([FromUri]string user, string pass)
{
string check = SQL.Reader("SELECT * FROM users WHERE username='" + user + "' AND password='" + pass + "'");
if (String.IsNullOrWhiteSpace(check))
{
return "error en credenciales";
}
DataTable horarios = SQL.table_read("SELECT * FROM horario_riego");
string json = Utils.ConvertDataTabletoJSON(horarios);
return json;
}
[HttpPost, Route("api/post")]
public void Post([FromBody]string value)
{
string i = value;
}
}
}
my global asax:
namespace AgroRiego
{
public class WebApiApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
GlobalConfiguration.Configure(WebApiConfig.Register);
}
}
}
and my webapiconfig:
namespace AgroRiego
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Configuración y servicios de API web
// Rutas de API web
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
}
i have more webforms inside the project (originally it was just html pages with serverside code, but i need to add a couple methods to retrieve and send data, help much appreciated!
EDIT1: i managed to reach HTTP 200 changing the URL but i can't reach the methods anyway (in debug mode it does not stop on the breakpoints) how can i route correctly the Api (so it is not Login.aspx) and how do i fix the methods reaching?
EDIT2: i read in documentation that i need this line in global:
RouteConfig.RegisterRoutes(RouteTable.Routes);
but im not using MVC does that matter? i tried reaching the routes with a brand new MVC Web Api and it yields "No Response"
use a routerprefix with your controller. So you access the URL as
http://localhost/routerprefix/router
HttpClient class can be use to send and receive HTTP requests and responses. Since you are trying to consume a WebApi from a aspx page, better way is to create a HttpClient instance
Below is a very simple implementation. Please check this url for further information
MSDN sample
HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync("http://localhost:49342/api/get");
if (response.IsSuccessStatusCode)
{
product = await response.Content.ReadAsAsync();
}
By the look of your set up, it seems correct
you have got:
config.MapHttpAttributeRoutes(); - setup the attribute route
config.Routes.MapHttpRoute( - setup the default route
GlobalConfiguration.Configure(WebApiConfig.Register); - to register at startup
so it should work.
I think the problem you are having is the way you are calling it
WebAPI routing work a little different to MVC
for example:
In you get method, the route is set as below
[HttpGet, Route("api/get")]
so you should call it {host}/api/get using a GET http method
in the screen shot, you are calling using {host}/api/get/Get - which would not have work, because no route would match
Same for your POST method
So give it another try and you should be able to reach it
The URL to add in the rest testing tool is
http://localhost:49342/api/get
Method type is GET
If you are calling this web api from aspx page use the httpClient class.
I am trying to catch 404 errors which are returned by the Asp.net Web API server.
However, Application_Error from inside Global.asax is not catching them.
Is there a way to handle these errors?
You might want to take a look at Handling HTTP 404 Error in ASP.NET Web API which has a step by step example
I know this is old, but I was also just looking for this, and found a very easy way that seems to work, so thought I'd add incase this can help someone else.
The solution I found, that works for me, is here. Also, this can be mixed with attribute routing (which I use).
So, in my (Owin) Startup class I just add something like..
public void Configuration(IAppBuilder app)
{
HttpConfiguration httpConfig = new HttpConfiguration();
//.. other config
app.UseWebApi(httpConfig);
//...
// The I added this to the end as suggested in the linked post
httpConfig.Routes.MapHttpRoute(
name: "ResourceNotFound",
routeTemplate: "{*uri}",
defaults: new { controller = "Default", uri = RouteParameter.Optional });
// ...
}
// Add the controller and any verbs we want to trap
public class DefaultController : ApiController
{
public IHttpActionResult Get(string uri)
{
return this.NotFound();
}
public HttpResponseMessage Post(string uri)
{
HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.NotFound, "I am not found");
return response;
}
}
Above you can then return any error object (in this example I am just returning a string "I am not found" for my POST.
I tried the xxyyzz (no named controller prefix) as suggested by #Catalin and this worked as well.
I am developing a website with ASP.net MVC3.
I have built it up and ran normally at local. Then when I deploy it with IIS 7.5, the site can display. All functionality works except the url is not changing when I switch in between actions and controllers(the url always shows "www.mysite.com" not "www.mysite.com/home/action"). Also, the title of pages are not shown. Instead of my slogan, it shows the domain url like www.mysite.com on the page title of browsers.
I followed the official deploy instruction of ASP.net with IIS.
Is there anyone knows what's the problem? Thanks in advance.
Here is my code for the Global.asax
public class MvcApplication : System.Web.HttpApplication
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleErrorAttribute());
}
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"ImageWall", // Route name
"ImageWall/{action}/{id}", // URL with parameters
new { controller = "ImageWall", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
}
}
Regards the title, in your views, do you use something like
ViewBag.Title = "Some Title"
In the HTML source of a page on your site, does the <title> element get populated? If not, then that could explain why you do not see the title.
Regards the url, can you post the code of your global.asax.cs file please (or global.asax.vb if you're using VB.NET). That is where route configuration can take place, so seeing that could help us explain why the url does not a show.
I have found the problem.
The problem is caused by the settings of Domain.com. As I am a fresher to deploy, I didn't set the "A Record" for all my domains. I just set the redirection to my IP.
I'm trying to figure out the madness behind the Web API routing.
When I try to post data like this:
curl -v -d "test" http://localhost:8088/services/SendData
I get a 404, and the following error message:
{"Message":"No HTTP resource was found that matches the request URI 'http://localhost:8088/services/SendData'.","MessageDetail":"No action was found on the controller 'Test' that matches the request."}
Here is the code for my test server.
public class TestController : ApiController
{
[HttpPost]
public void SendData(string data)
{
Console.WriteLine(data);
}
}
class Program
{
static void Main(string[] args)
{
var config = new HttpSelfHostConfiguration("http://localhost:8088");
config.Routes.MapHttpRoute(
name: "API Default",
routeTemplate:"services/SendData",
defaults: new { controller = "Test", action = "SendData"},
constraints: null);
using (var server = new HttpSelfHostServer(config))
{
server.OpenAsync().Wait();
Console.WriteLine("Press Enter to quit.");
Console.ReadLine();
}
}
}
More generally, why has the ASP.NET team decided to make the MapHttpRoute method so confusing. Why does it take two anonymous objects....how is anyone supposed to know what properties these objects actually need?
MSDN gives no help: http://msdn.microsoft.com/en-us/library/hh835483(v=vs.108).aspx
All the pain of a dynamically typed language without any of the benefit if you ask me...
Agree with you, it's a hell of a madness, you need to specify that the data parameter should be bound from the POST payload, since the Web API automatically assumes that it should be part of the query string (because it is a simple type):
public void SendData([FromBody] string data)
And to make the madness even worse you need to prepend the POST payload with = (yeah, that's not a typo, it's the equal sign):
curl -v -d "=test" http://localhost:8088/services/SendData
You could read more about the madness in this article.
Or stop the madness and try ServiceStack.
Use this signature and it will work every time.
public class TestController : ApiController
{
[HttpPost]
[ActionName("SendData")]
public HttpResponseMessage SendData(HttpRequestMessage request)
{
var data = request.Content.ReadAsStringAsync().Result;
Console.WriteLine(data);
}
}
Try with the following change,
public class TestController : ApiController
{
[HttpPost]
[ActionName("SendData")]
public void SendData(string data)
{
Console.WriteLine(data);
}
}
The ActionName attribute might fix the issue. Otherwise, you can also the name convention "Post"
public void Post(string data)
{
Console.WriteLine(data);
}
And send an Http Post directly to "services" without SendData.
I am working on a very simple application, using MVC2 Preview 1.
I have a controller named ContentController. My problem is that /Content/Index works correctly, but /Content/ returns a 404. I am running the application on the Studio Development Server.
Tested with RouteDebugger but /Content/ returns a 404, and does not display any debugging information.
I have not changed the routing code:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
This is my controller:
public class ContentController : Controller
{
IRepository _repo = new SimpleRepository("db", SimpleRepositoryOptions.RunMigrations);
public ActionResult Index()
{
var content = _repo.GetPaged<Content>(0, 20);
return View(content);
}
It's a shot in the dark, but do you have a directory named /Content/ as well?
/Content is a controller, which is basically just a collection of actions. ASP.NET MVC needs to know WHICH action you want to run, so by leaving out the action asp.net mvc doesn't know what action to return and gives a 404.
You can tell it a default either by adding a route:
eg:
routes.MapRoute("ContentDefault", "Content", new {controller = "Content", action = "Index"});
The attributes are defined as follows:
'ContentDefault`: Name of the Route (must be unique in your routing table)
Content: The URL segment (try changing this to 'Content/Much/Longer/URL' and then go to http://localhost/Content/Much/Longer/URL to see how this works)
new {controller=.., action=...}: which controller/action combo to run for this route.
You could also override HandleUnknownAction in your controller:
protected override void HandleUnknownAction(string actionName)
{
return RedirectToAction("index");
}
Oh and incidentally, an extra piece of advice about routing.... if you add something to the route in braces { } these will be passed to the action as an attribute.
e.g. /Content/Much/Longer/Url/{page}
so the URL http://localhost/Content/Much/Longer/Url/999
will pass the 999 into your action, as the page attribute
public ActionResult Index(int Page) { }
I love MVC - never going back to WebForms - this is how web development should be!
