关于c＃：HttpClient PostAsync和SendAsync之间的区别

Difference between HttpClient PostAsync and SendAsync

在一个WPF前端的项目上工作，并尝试处理对HttpClient的异步调用，而我一直在四处寻找尝试使PostAsync正常工作，但是它通常似乎死锁，或者在即使有较大的超时值，后期响应也会超时，并且提琴手中的响应可见。

因此，过了一会儿，我决定尝试使用HttpClient上的其他方法，并且它们起作用了，请首先尝试。不知道为什么。

我一直使用awaits，asyncs和.ConfigureAwait(false)清理到WPF按钮(我认为)：

按键：

1
2

4

private async void Generate_Suite_BTN_Click(object sender, RoutedEventArgs e)
{
await suiteBuilder.SendStarWs().ConfigureAwait(false);
}

XmlDoc加载：

1

6

internal async Task SendStarWs()
{
var xmlDoc = new XmlDocument();
xmlDoc.Load("C:\\\\Temp\\\\file.xml");
await StarWSClient.SendStarMessage(xmlDoc).ConfigureAwait(false);
}

发信息：

1

private static readonly HttpClient Client = new HttpClient {MaxResponseContentBufferSize = 1000000};

public static async Task<STARResult> SendMessage(vars)
{
var response = await SendRequestAsync(url, contentNew, Client).ConfigureAwait(false);
return new STARResult(response, hash);
}

我会立即对我的端点调用" 500s"，这是我期望的：

var response = await SendRequestAsync(url, contentNew, Client).ConfigureAwait(false);

private static async Task<HttpResponseMessage> SendRequestAsync(string adaptiveUri, StringContent content, HttpClient httpClient)
{
HttpResponseMessage responseMessage = null;
try
{
responseMessage = await httpClient.SendAsync(new HttpRequestMessage(HttpMethod.Post, adaptiveUri)).ConfigureAwait(false);
}
catch (Exception ex)
{
if (responseMessage == null)
responseMessage = new HttpResponseMessage
{
StatusCode = HttpStatusCode.InternalServerError,
ReasonPhrase = $"SendRequestAsync failed: {ex.Message}"
};
}
return responseMessage;
}

Post变量返回TaskCancellationException，并带有超时消息，而不管超时值如何：

var response = await PostRequestAsync(url, contentNew, Client).ConfigureAwait(false);

private static async Task<HttpResponseMessage> PostRequestAsync(string adaptiveUri, StringContent content, HttpClient httpClient)
{
HttpResponseMessage responseMessage = null;
try
{
responseMessage = await httpClient.PostAsync(adaptiveUri, content).ConfigureAwait(false);
}
catch (Exception ex)
{
if (responseMessage == null)
responseMessage = new HttpResponseMessage
{
StatusCode = HttpStatusCode.InternalServerError,
ReasonPhrase = $"PostRequestAsync failed: {ex.Message}"
};
}
return responseMessage;
}

我的端点对其他软件的响应正常，因此我很确定端点是可靠的，我无法理解为何发送响应未被阻止时阻止了响应。
