同步调用httpclienthandler不等待

Question

I do a call to the following, but I notice that if the webapi i'm calling takes longer than 41 seconds it will just return leading to a null value.

I tried setting the client.timeout setting but that did not seem to make a difference. What am I doing wrong?

        HttpClientHandler handler = new HttpClientHandler()
            {
                Credentials = credentials
            };            
        using (var client = new System.Net.Http.HttpClient(handler))
        {
            client.Timeout.Add(new TimeSpan(1, 0, 0));
            client.BaseAddress = new Uri(site.ToString());
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(
                new MediaTypeWithQualityHeaderValue("application/json"));
            try
            {
                string target = site.ToString() + apiPath + query;
                var response = client.GetAsync(target).Result;                   
                response.EnsureSuccessStatusCode();
                if (response.IsSuccessStatusCode)
                {
                    var result =                            
                        response.Content.ReadAsStringAsync().Result;
                    if (!String.IsNullOrEmpty(result))
                    {
                        return result;
                    }
                    else
                    {       
                        return null;
                    }
                }
                else
                {                 
                    return null;
                }
            }
            catch (Exception ex)
            {             
                return null;
            }
        }

This line:

client.Timeout.Add(new TimeSpan(1, 0, 0));

does nothing, because TimeSpan is immutable. It just returns a value, which you then don't use. I presume you instead want:

client.Timeout = new TimeSpan(1, 0, 0);
