We are at the stage of deploying a project to our client's test server but unfortunately, we are receiving 405 errors every time our application tries to make calls to any of the Web Api methods we have made available.
My WebApi calls are defined as follows:
public class TourController : ApiController
{
[HttpPost]
public JsonCollection RequestTours([FromBody] DateRequest request){
// Implementation goes here
}
[HttpPost]
public GroupTour RequestTour([FromBody] int request){
// Implementation goes here
}
}
My WebApi routing is as follows:
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
These calls work as defined when run locally though Visual Studio with no ammendments however, when we place them on our client's IIS test server we are consistently receiving 405 errors when calling the methods via AJAX (primary method) or via URL.
As suggested in other posts, we have tried defining the following in system.webServer:
<modules runAllManagedModulesForAllRequests="true" />
<handlers>
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
We have also tried adding the following to no avail:
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule"/> <!-- add this -->
</modules>
<handlers>
<remove name="WebDAV" />
...
</handlers>
We are currently at a loss as we have tried most of the suggestions offered on similar Stack Overflow posts around the same subject. Any help or suggestions on this issue would be greatly appreciated!
N.B.
Just for the record, my calling method via Javascript / JQuery is doing the following:
function populateInstances(date) {
var $container = $('#id-tour_4');
$.ajax({
url: '/api/tour/requesttours',
type: 'POST',
data: { Date: date },
dataType: 'json',
success: function (data) {
var htmlstring = '';
$container.empty();
if (data.Results.length > 0) {
for (var i = 0; i < data.Results.length; i++) {
htmlstring += '<div class="book-title">' + data.Results[i].Name + '</div>';
htmlstring += '<div class="tour_select_list_div">';
htmlstring += '<ul class="tour_select_list">';
for (var j = 0; j < data.Results[i].Instances.length; j++) {
htmlstring += '<li><label for="id-tour_4_' + j + '"><input id="id-tour_4_' + j + '" type="radio" value="' + data.Results[i].Instances[j].TourId + '" name="BookTour.Instance" data-availability="' + data.Results[i].Instances[j].Availability + '" data-adultprice="' + data.Results[i].Instances[j].AdultPrice + '" data-childprice="' + data.Results[i].Instances[j].ChildPrice + '">';
htmlstring += data.Results[i].Instances[j].StartTime + ' - ' + data.Results[i].Instances[j].Title + '</label></li>';
}
htmlstring += '</ul>';
htmlstring += '</div>';
}
} else {
htmlstring += 'There are no tours departing on this date';
}
$container.append(htmlstring);
}
});
}
