试图从VS2019中的控制台应用程序调用简单的POST API

Question

我正在尝试调用简单的POST API，以通过Console App创建Zendesk Ticket。我在VS2019中创建了C＃核心控制台应用程序，并粘贴了应该创建New Ticket的简单代码。代码可以在其他应用程序中工作，但在控制台应用程序中，该应用程序只是从调试中注销...电话永远不会过去...

using (var httpClient = new HttpClient())
            {
                using (var request = new HttpRequestMessage(new HttpMethod("POST"), "https://testhelp.zendesk.com/api/v2/tickets.json"))
                {
                    try
                    {
                        var base64authorization = Convert.ToBase64String(Encoding.ASCII.GetBytes("[email protected]:testPassword"));
                        request.Headers.TryAddWithoutValidation("Authorization", $"Basic {base64authorization}");

                        request.Content = new StringContent("{\"ticket\": {\"subject\": \"My first Ticket!\", \"comment\": { \"body\": \"The ticket is from API.\" }}}");
                        request.Content.Headers.ContentType = MediaTypeHeaderValue.Parse("application/json");
                        ServicePointManager.Expect100Continue = true;
                        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
                        HttpResponseMessage response = await httpClient.SendAsync(request).ConfigureAwait(false);
                        string content = await response.Content.ReadAsStringAsync().ConfigureAwait(false);
                        Console.WriteLine(response);
                    }
                    catch (Exception ex)
                    {
                        Console.WriteLine(ex);
                    }
                }
            }
        }

我想念的是什么？

我的猜测是，通过异步调用，您的程序在控制台版本中就已经结束了。

通过在主要方法中进行一次简单的等待即可解决？

 static void Main(string[] args)
    {
        var t = new Task(createTicket);
        t.Start();
        while(! t.IsCompleted) //IsCompleted is probably not robust enough but you can see if your call ever finishes this way
        {
            System.Threading.Thread.Sleep(100);
        }
    }

    async static void createTicket()
    {
        using (var httpClient = new HttpClient())
        {
            using (var request = new HttpRequestMessage(new HttpMethod("POST"), "https://testhelp.zendesk.com/api/v2/tickets.json"))
            {
                try
                {
                    var base64authorization = Convert.ToBase64String(Encoding.ASCII.GetBytes("[email protected]:testPassword"));
                    request.Headers.TryAddWithoutValidation("Authorization", $"Basic {base64authorization}");

                    request.Content = new StringContent("{\"ticket\": {\"subject\": \"My first Ticket!\", \"comment\": { \"body\": \"The ticket is from API.\" }}}");
                    request.Content.Headers.ContentType = MediaTypeHeaderValue.Parse("application/json");
                    ServicePointManager.Expect100Continue = true;
                    ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
                    HttpResponseMessage response = await httpClient.SendAsync(request).ConfigureAwait(false);
                    string content = await response.Content.ReadAsStringAsync().ConfigureAwait(false);
                    Console.WriteLine(response);
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex);
                }
            }
        }
    }
