ASP.NET Web API 在 IIS 中发布时不起作用？

Question

I have built an ASP.NET Web API when I run or brows it from Visual Studio its work fine, but when I host it in IIS and try to browse it its not work and give me the following error:

HTTP 400 error It's not you, it's this link (it appears to be broken)

here where i publish my web service

the API method is

 [HttpGet]
    [Route("findall")]
    public HttpResponseMessage findAll()
    {
        try
        {
            var response = new HttpResponseMessage(HttpStatusCode.OK);
            response.Content = new StringContent(JsonConvert.SerializeObject(mde.Products.ToList()));
            response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");

            return response;

        }
        catch
        {
            return new HttpResponseMessage(HttpStatusCode.BadRequest);
        }
    }

I send the following request to it :

http://localhost:9810/api/product/findall

how can i fix this issue ?

Answer 1

Based on screenshot, you have deployed your application as virtual app on the Default Site. And /myserver is defined as virtual path. It means that your API root URL would be:

http://localhost:{IIS_PORT}/myserver/{YOUR_APP_ROUTES}

For default website port is 80; If URL from your post ( http://localhost:9810/api/product/findall ) is working on IIS-express correctly, try to invoke this URL for your IIS deployment:

http://localhost/myserver/api/product/findall

Answer 2

Excute this command in command prompt

%windir%\\Microsoft.NET\\Framework\\v4.0.21006\\aspnet_regiis.exe -i

for me its solved the issue
