This is my first time trying to use the WEB API in a project and am not having any success with it...
I keep getting 404 errors when I try and reach my api route in Fiddler.
I tried looking a lot on the web and even here at the following link, but there are so many combinations, that I'm not sure what would work.
HTTP 404 Page Not Found in Web Api hosted in IIS 7.5
If somebody can please help me with this to get the right settings I would really appreciate it.
Here is my code:

WebApiConfig.cs file:

using System.Web.Http;
namespace FuelTicketImageRetrievalSvc
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API configuration and services

config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
}
Global.asax.cs file:
using FuelTicketImageRetrieval;
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
namespace FuelTicketImageRetrievalSvc
{
public class WebApiApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
GlobalConfiguration.Configure(WebApiConfig.Register);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
}
}
Controller method that I'm trying to call. It's just a dummy method that simply returns null with no parameters. It's name is FuelTicketImageRetrievalController:
public string GetSpecificFuelTicket()
{
try
{
return null;
}
catch (Exception ex)
{
return null;
}
}
The name of my project is called FuelTicketImageRetrievalSvc. I have verified through the web settings in the project that IIS Express is being used and is set to
http://localhost:11581/
url path call.
http://localhost:11581/FuelTicketImageRetrievalSvc/api/GetSpecificFuelTicket
You don't need FuelTicketImageRetrievalSvc in uri, it should work simply with /api/...
that's what your route matches, having svc name there causes it to not match.
You need to add your controller in the path and remove your project
http://localhost:11581/api/FuelTicketImageRetrieval/GetSpecificFuelTicket
You remove the Controller part when referencing it - the /FuelTicketImageRetrieval/ is from the FuelTicketImageRetrievalController not the project. Web API will auto add the controller back on the name when looking for the correct class.
For a quick guaranteed run (and sometimes preferred approach), add HTTP action prefix and route attributes before your method:
[HttpGet]
[Route("api/Products/SpecificFuelTicket")]
public string GetSpecificFuelTicket()
{
try
{
return null;
}
catch (Exception ex)
{
return null;
}
}
Now, you can access it using URL:
http://localhost:xxxx/api/products/SpecificFuelTicket
Points to note:
HTTPGet ensures that only Get action is mapped to this method
Route value ensures a direct mapping to a URL. As REST standard, "Get", "Delete" etc.. are not used as prefix in URL. The HTTP action is used for that.
Some methods are automatically mapped to suitable URLs, but since your class name is "FuelTicketImageRetrievalController" and method name is "GetSpecificFuelTicket", it is not trivial.
Returning null is not an issue. it is returned serialized as "null".
For your another question to Charles, if you want to use URL "localhost:xxxx/api/GetSpecificFuelTicketAsync/6460194", and your method signature takes int, you can change the route prefix as following (again, not using "Get" in the route):
[HttpGet]
[Route("api/Products/SpecificFuelTicket/{value}")]
public string GetSpecificFuelTicket(int value)
{
try
{
return "Your ticket is " + value.ToString();
}
catch (Exception ex)
{
return null;
}
}
However, as Charles suggested, using "api/Products/SpecificFuelTicket?value=6460194" format is perhaps better. Any parameter name in the method is automatically mapped to similar name query parameter. So, your method'd look like:
[HttpGet]
[Route("api/Products/SpecificFuelTicket")]
public string GetSpecificFuelTicket(int value)
{
....
}
For, a detailed understanding of URL mapping and routing web-API, refer to link:

I originally had a 404 error when I added WebApi support to my Mvc solution.
My global.asax.cs contained the lines:
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
GlobalConfiguration.Configure(WebApiConfig.Register);
What I found is that when I changed he WebApiConfig line, so that the code block became:
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
it fixed my problem

default:
return Request.CreateErrorResponse(HttpStatusCode.NotFound, " value of gender is wrong");

what could be the reason?
Your code is fine. It's your url that is wrong:
http://localhost:61491/api/Employees/gender=female
I will give a quick solution as to what it should be, then give more details I highly recommend you read if you are learning APIs. Your URL should be:
http://localhost:61491/api/Employees?gender=female
With C# APIs you can send data in 3 possible ways:
Query Parameter
Route Parameter
In the Request Body
Query Parameters
This is the default type. Meaning if you don't specify the method it will always assume your inputs are query parameters. Not only that, but query parameters are by default optional and nullable. If you put in a null for a query parameter it will be assigned the default value.
Query parameters can be identified in a URL by the ? mark. Any data after that are query parameters and can be assigned in any order. For example:
MyUrl?Name=Jhon&Age=20&Sex=M
The & shows it's a split. The data above will map to the endpoint:
public HttpResponseMessage Get(string name, string sex, int age)
The paremeters can be in any order. It will map correctly.
Route Paremeters
These are queries taken directly from route. Adapting your request it will look like this:
/api/Employees/gender/female
And the endpoint itself will look as follow:
[HttpGet("gender/{sex}")]
public HttpResponseMessage Get([FromRoute] string sex) {...}
You can't by default use Route parameters, you will need to specify it is a route parameter by:
Putting the parameter in the route for the end point in brackets {}
Indicate with the [FromRoute] attribute that the api should use the route to get the attribute. By Default the route is required. You cannot use it as an optional parameter.
Body Parameters
This is simply you read the body of the request as a parameter. Good when you are posting or putting data Not going into too much detail but it will look as follow:
public HttpResponseMessage Get([FromBody] Model data) {...}
It is important to note that the [FromBody] parameters aren't compatible with Get requests.
Request Types
One important thing you will need to know is the request types. There are many but by default it will always be a Get request.
Your code:
public HttpResponseMessage Get(...) {...}
Is not a get reqest because you wrote GET. You can name that request whatever you like such as:
public HttpResponseMessage ThisIsMyPostRequest(...) {...}
But you will still be able to retrieve data using a GET request. The Specify what type of requests it is, you can add a http attribute tag:
[HttpGet]
public HttpResponseMessage MyGetFuncName(){...}
[HttpPost]
public HttpResponseMessage MyPostFuncName(){...}
[HttpPut]
public HttpResponseMessage MyPutFuncName(){...}
[HttpDelete]
public HttpResponseMessage MyDeleteFuncName(){...}
[HttpOptions]
public HttpResponseMessage MyOptionsFuncName(){...}
[HttpHead]
public HttpResponseMessage MyHeadFuncName(){...}
...
It is really that easy. The different HttpRequest mostly work the same. But there are a few differences. The most common used are GET, POST, PUT and DELETE.
This becomes usefull when say you want to use the same route but different functions. For example GET and DELETE can be on the same route:
/api/Employees/Byname?name=Jhon
but depending on the request type will either return the user or delete it.
Custom Routes
The last important and powerfull thing you will need to know is Routes. If I am not mistaken at the top of your controller page you have the following attribute:
[Route("[controller]")]
or
[Route("api/[controller]")]
What that function does is it ands a prefix to all of the requests on the controller. Now you can actually add this to individual functions as well. Meaning if you have multiple GET functions on a single page, this will be essential to keep it working properly. Example:
[Route("ByGenders")]
public HttpResponseMessage Get(string gender="All")
/api/Employees/ByGenders?gender=female
...
[Route("Byname")]
public HttpResponseMessage Get(string name)
/api/Employees/Byname?name=Jhon
But it can actually be combined with the HttpRequest attributes. Meaning the above will be equivalent to:
[HttpGet("ByGenders")]
public HttpResponseMessage Get(string gender="All")
[HttpGet("Byname")]
public HttpResponseMessage Get(string name)
Ofcourse you can put all of the above together into a unique endpoint with a lot of details. Below is a small example:
[HttpGet("GetWithParams/{requiredInput}")]
public IActionResult GetWithParams(
[FromRoute] string requiredInput,
[FromQuery] string optionalInput)
{
return Ok($"Required Input: {requiredInput} | Optional Input: {optionalInput}");
}
Or
[HttpPost("UserId/{id}")]
public IActionResult SubmitApplication(
[FromRoute] int id,
[FromBody] UserApplicationModel application)
{
return BadRequest();
}
Hello I have more than one project connecting to a certain DB that is CodeFirst Entity Framework.
All Projects are able to connect successfully except for one stubborn one.
The error I am getting is: Keyword not supported: 'port'
I have looked through countless stackoverflow questions, mysql forums, entity framework forums etc. including:
MappingException Edm.String not compatible with SqlServer.varbinary
Keyword not supported in MySQL's connection string
Keyword not supported: 'metadata' + MySQL
My connection string looks like:
server=myservername;port=3306;uid=myaccount;database=mydb;pwd=mypwd123
My db.cs file looks like:
public partial class MyDB : DbContext
{
public MyDB ()
: base("server=myservername;port=3306;uid=myaccount;database=mydb;pwd=mypwd123")
{
Logger.Trace("test123");
}

get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<MyItem>()
.Property(e => e.Content)
.IsUnicode(false);
}
}
When I remove the port:3306 from the connection string I get this:

The argument of the used base DbContext constructor is called nameOrConnectionString. Hence it supports a name of a connection string from the configuration file, or like in your case an actual connection string.
The problem with the later is that it doesn't allow specifying the provider name as with the former coming from the configuration, in which case EF uses the one specified in the defaultConnectionFactory configuration element, which in your case is System.Data.Entity.Infrastructure.SqlConnectionFactory, in other words - Sql Server, hence the port not supported exception.
There are several ways to fix the issue.
(A) Change the defaultConnectionFactory configuration:
<defaultConnectionFactory type="MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6"></defaultConnectionFactory>
(B) Use named configuration connection string and specify explicitly the provider:
<connectionStrings>
<add name="MyDB" providerName="MySql.Data.MySqlClient" connectionString="server=myservername;port=3306;uid=myaccount;database=mydb;pwd=mypwd123" />
</connectionStrings>
and change the constructor to
public MyDB()
{
// ...
}
or if the name is different than your DbContext derived class name:
public MyDB() : base(connection_string_name)
{
// ...
}
(C) Use DbConfigurationTypeAttribute:
[DbConfigurationType(typeof(MySql.Data.Entity.MySqlEFConfiguration))]
public class MyDB : DbContext
{
// ...
}
I had this problem whilst developing a Web Application on Core 2. I had to change the default database connection used from SqlServer to MySql in the Startup.cs file where the application is configured.
The error similar to the one listed above comes while working with ASP.net core and Database. The default database Provider with the ASP.net core is the SQL Server but, in case you are using a different provider for example, PostgreSQL and didn't correctly write or configure the DBContext code in the startup.cs
For example - Following code is written with an intent to connect to PostgresSQL then it will result in error ArgumentException: Keyword not supported: 'port'.
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
var connection = #"Server=localhost;Port=5432;Database=NewDB;User Id=xxxxx;Password=cr#aaaa;";
services.AddDbContext<BloggingContext>(options => options.UseSqlServer(connection));
// ...
}
And the reasons is user is trying to connect to PostgreSQL but did change the default Option UseSQLServer after configuring the PostgreSQL string.
To fix the issue change the option
options.UseSqlServer(connection)) -> options.UseNpgsql(connection))
I definitively solved the problem using the MySql Connector 8.0.x and following instructions on this link: https://davidsekar.com/asp-net/mysql-error-the-provider-did-not-return-a-providermanifesttoken.
in details:
Install MySql.Data.EntityFramework. Do not install Install MySql.Data.Entity!
Configure web.config / app.config in this way:
2.1. Change the <entityFramework> tag to <entityFramework codeConfigurationType="MySql.Data.EntityFramework.MySqlEFConfiguration, MySql.Data.EntityFramework">
2.2. Add/change the provider. It has to be: <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.EntityFramework" />
2.3. Connection string now can be server=myservername;port=3306;uid=myaccount;database=mydb;pwd=mypwd123
Open your DbContext's configuration class (if presente) and place the following code in it's constructor:
SetSqlGenerator("MySql.Data.MySqlClient" new MySql.Data.EntityFramework.MySqlMigrationSqlGenerator());
In my case, connection string with explicit port has to be delimited by ,.
E.g.: Data Source=123.45.123.45,1433;...
Sometimes it's the simplest thing. Mine was a copy-paste error when I missed the "Server=" at the beginning of the connection string.
Using Entity's visual designer I have created the most basic entity possible. I want to seed some sample data to a database I created which holds the schema for this basic entity on Azure. I want to use this db in an asp.net web form but when I go to seed the init data I get an SQL timeout error.
I am aware that when using entities Database.SetInitializer the seed operation is only called when the context is used so I forced the initialization. It seems to try yet I still get the timeout. I created a basic console application and wrote a test program to load some values into the table and it worked fine so I know it is not the connection to the DB, it is something to do with the Seeding.
Here is the actual error:
A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in EntityFramework.SqlServer.dll
An exception of type 'System.Data.SqlClient.SqlException' occurred in EntityFramework.SqlServer.dll but was not handled in user code
Additional information: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

I know this is an old question, but in case anyone stumbles here from Google... you need to increase your CommandTimeout to give Azure enough time to create the db.
There is an incredibly detailed StackOverlow answer explaining why here:
Timeout when setting up Entity Framework connecting to Azure
The gist of it is that you need to add a single line into your DbContext constructor:
public MyContext() : base("name=MyContext")
{
// three minute command timeout
this.Database.CommandTimeout = 180;
}
I am struggling to setup the httpErrors section correctly in my web.config to capture both ASP.NET MVC errors and IIS errors. I am getting 403 status codes and blank pages. I am testing with 404 errors by typing incorrect URLS and file names in the URL, for example:
www.mywebsite.com/test
www.mywebsite.com/test.html
I am using the latest version of ASP.NET MVC 5. This web application is running on IIS 7.5 with an application pool using integrated mode.
This is what my web.config looks like at the root of the application (this is all that I currently have):
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="webpages:Version" value="3.0.0.0"/>

My global.asax.cs file:
public class MvcApplication : HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RouteConfig.RegisterRoutes(RouteTable.Routes);
}
protected void Application_Error()
{
// Break point has been set here for testing purposes
}
protected void Application_EndRequest()
{
if (Context.Response.StatusCode == 404)
{
// Break point has been set here for testing purposes
}
}
}
My error controller:
public class ErrorController : Controller
{
public ActionResult Index()
{
// Break point has been set here for testing purposes
Response.StatusCode = 500;
return View();
}
public ActionResult Forbidden()
{
// Break point has been set here for testing purposes
Response.StatusCode = 403;
return View();
}
public ActionResult NotFound()
{
// Break point has been set here for testing purposes
Response.StatusCode = 404;
return View();
}
}
They have their corresponding views in the Views folder.
My break points are never hit in my error controller. I don't understand why? I have looked at many examples on Stackoverflow and this is how every suggests that I do it. When would the break points not be reached given my code? All that happens is a 403 error status and a BLANK white page. The break points in Application_Error() and Application_EndRequest() are hit, but not the break points in the error controller.
There is code that I can write in Application_Error() and Application_EndRequest() that lets me set the error controller and action method, but why do that if I can use the web.config? This should also work?
Man, you have mentioned statusCode as 404 then how can you expect as 200 OK ? :)
just remove Response.StatusCode = 404; line from action method
Bellow code should work
public ActionResult NotFound()
{
return View();
}
I'm deploy my MVC 3 application to a server and, after solve several issues related with missing MVC dlls (the server does not have MVC installed) it start to give a error:
Firefox "The page isn't redirecting properly"
Chrome "This webpage has a redirect loop"
IE "This page can't be displayed"
I found people saying that it is something cookie related, but I can't understand how to solve the problem.
I never see the default page whether.
I suspect there is a problem with my Global.asax file or my Web.Config.
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(
"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);
}
}
And there is a part of my Web.Config without AppSettings, connectionStrings and system.serviceModel:

<p>Password:<input type="password" name="pwd" /></p>

<input type="submit" value="Login" />

}
I try to deploy a dummie MVC application and it works! =/
Can you help me?
Thanks
There's probably a problem with your MVC installation. Make sure you install MVC correctly.
I'm guessing that your routes are not properly registered and thus if you go to your app's home page it will show you a 404. This gets picked up by this line in the web.config:
<error statusCode="404" redirect="/Error/PageNotFound" />
and redirects you to that page, which also throws a 404, redirecting you again to the same page, and so on and so on, causing the redirect loop.
For debugging purposes, you could comment out that line and check whether your routes are registered or not.
I discover that MVC runs a method called Initialize, in my BaseController, before any other:
protected override void Initialize(System.Web.Routing.RequestContext requestContext)
{
...
}
Inside that method I has a verification to know if user is authenticated and when not I do a Session.Abandon(); and a strange thing (I don't know why):
if (!requestContext.HttpContext.Request.CurrentExecutionFilePath.Equals("/MyWebSite/"))
Response.Redirect("~/", true);
It runs me into a infinite loop because the request page was MyNewWebsite insted MyWebSite...
Sorry and thank you for your patience
