UWP中的POST请求未发送

Question

我为 UWP 编写应用程序

我像这样从后端接收 json：

string url = "http://api.simplegames.com.ua/index.php/?wc_orders=all_orders";
{
    string jsonString;

    using (var httpClient = new System.Net.Http.HttpClient())
    {
        var stream = await httpClient.GetStreamAsync(url);
        StreamReader reader = new StreamReader(stream);
        jsonString = reader.ReadToEnd();
    }

    return jsonString;
}

我尝试像这样发送 POST 请求

OrdersList = new List<RootObject>(rootObjectData);
using (HttpClient httpClient = new HttpClient())
{
    httpClient.BaseAddress = new Uri(@"http://api.simplegames.com.ua");
    httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    httpClient.DefaultRequestHeaders.AcceptEncoding.Add(new StringWithQualityHeaderValue("utf-8"));

    string endpoint = @"/post_from_local.php";

    try
    {
        HttpContent content = new StringContent(JsonConvert.SerializeObject(OrdersList), Encoding.UTF8, "application/json");
        HttpResponseMessage response = await httpClient.PostAsync(endpoint, content);

        if (response.IsSuccessStatusCode)
        {
            string jsonResponse = await response.Content.ReadAsStringAsync();
            Debug.WriteLine(jsonResponse);
            //do something with json response here
        }
    }
    catch (Exception)
    {
        //Could not connect to server
        //Use more specific exception handling, this is just an example
    }
}

但是，后端开发人员说他看到空行，但没有收到数据。

感谢您的帮助。我的错误在哪里？

改变这一行：

var stream = await httpClient.GetStreamAsync(url);

到：

var stream = httpClient.GetStreamAsync(url).Result;
