WebAPI HTTPDelete method not found via request but found in Swagger

Question

I have API controller with method:

    [Route("campaigns")]
    [HttpDelete]
    public async Task<IHttpActionResult> Delete(string brandId,string campaignId)
    {
        try
        {
            var merchantId = CurrentUserInfo.GetMerchantId();
            await _service.DeleteAsync(merchantId, brandId, campaignId);
            return StatusCode(HttpStatusCode.NoContent);
        }
        catch (Exception e)
        {
            Log(e);
            return BadRequest(e.Message);
        }
    }

And from angularJS app I sending request:

 $http.delete(config.resourceNames.campaign, { params: { brandId: brandId, campaignId: campaignId } })
            .then(function (response) {
                return response;
            }, function (error) {
                return error;
            });

Config file:

 var resourceNames = {
    campaign: '/api/campaigns'
};

So the routing is valid. But the request always return 404 NOT FOUND .

I checked it via Swagger and that DELETE method is visible at the list but when I try to use it. It also return NOT FOUND .

Why this happing?

Edit:

While using "ISS Express" there is error 404 but when I switch to "Local ISS" the error change to 405 Method not allowed.

Answer 1

可能你需要写：

[Route("api/campaigns")]

Answer 2

I have run into this a couple of times. While I am not certain what the underlying cause is, I can say that naming routes has helped tremendously. Try this:

[Route("campaigns", Name = "delete-campaign")]
