I'm trying to set up a scheduled task, but I think I must be missing some key concept. Here's what I've got so far.

In umbracoSettings.config, I've got the following:

  <scheduledTasks>
    <task log="true" alias="import-from-blogs" interval="60" url="http://localhost:49244/Umbraco/Api/BlogApi/Import" />
  </scheduledTasks>

Then, I've created an API Controller:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Umbraco.Web.WebApi;

namespace psclistens.Controllers
{
    public class BlogApiController : UmbracoApiController
    {
        public String Import()
        {
            return "foo";
        }
    }
}

When run Umbraco, I see this in the UmbracoTraceLog.txt file:

System.Net.ProtocolViolationException: Cannot send a content-body with this verb-type.
   at System.Net.HttpWebRequest.CheckProtocol(Boolean onRequestStream)
   at System.Net.HttpWebRequest.BeginGetRequestStream(AsyncCallback callback, Object state)

Any hints or suggestions would be appreciated.

I've tried a bunch of different stuff and I always get the same error. I'm beginning to suspect that scheduled tasks are broken in Umbraco 7. Can anyone confirm or deny this?

Have you tried the [AcceptVerbs("GET")] attribute in your api controller?

Hi,

i think Andrew is right. Try to add [HttpGet] to your method:
```
namespace psclistens.Controllers {

[System.Web.Http.HttpGet]
public class BlogApiController : UmbracoApiController
{
    public String Import()
    {
        return "foo";
    }
}
```
}

If it still won´t work, try call a normal url from the taskmanager, to check if it is broken or you have a problem in your api.

Best regards René

Hi,

I have tried above fix by adding "[System.Web.Http.HttpGet]" to API controller but it is still not working. Please suggest.

Thanks

Not sure if that was a typo on René's post - the [HttpGet] decorator needs to go above the method, not the class.
```
namespace psclistens.Controllers 
{
    public class BlogApiController : UmbracoApiController
    {
        [System.Web.Http.HttpGet]
        public String Import()
        {
            return "foo";
        }
    }
```
I don't know if this will fix your issue though.

Sorry, my mistake. Thank you Hywel!

@Sanjay, have you tried calling a normal url from scheduletask?

Hi Hywel,

Sorry my bad when I said on controller. I did try this above on method not controller but it didn't work. I am able to call the url in browser and it does work and perform the required task which proves the url is working fine. Also I tried a different url also which doesn't do anything but that is also not working and giving the same error

================ 2015-09-29 14:24:55,369 [135] ERROR Umbraco.Web.Scheduling.ScheduledTasks - [P6844/T104/D3] An error occurred calling web task for url: http://localhost:8080/enjoy System.Net.ProtocolViolationException: Cannot send a content-body with this verb-type.

===========================

I have seen some post where its said it is fixed in 7.3.0 RC but I want to stay of 7.2.8 version and want a fix. Please suggest.

Thanks Sanjay

Hi Sanjay,

do you have an Access-Control-Allow-Origin in your method? Maybe that could make it work.

HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");

Best René

Hi Rene,

Thanks for your reply but no luck with HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");

Do you think you can suggest something else to make it work please?

Thanks Sanjay
