如何使用 System.Net.Http.HttpClient 在 POST 后使用 AllowAutoRedirect

这是创建客户端和POST对象的代码。我的理解是，设置 AllowAutoRedirect = true 将使客户端能够遵循重定向然后执行 GET，我将能够反序列化所述对象。到目前为止，我的测试被证明是不成功的。我可能忽略了什么吗？

Web API 终结点：

public HttpResponseMessage Post([FromBody] Contact contact) {
    try {
        // Add user
        ...
        var msg = Request.CreateResponse(HttpStatusCode.Created);
        msg.Headers.Location = new Uri(Request.RequestUri + "/" + customer.Person.PersonID);
        return msg;
    } catch (ValidationException tve) {
        var apiError = new ApiResponseMessage { Message = "Invalid contact" };
        foreach (var message in FilterErrors(tve.Messages)) {
            if (message.Contains("required", StringComparison.OrdinalIgnoreCase)) {
                apiError.Errors.Add(new ApiErrorMessage {
                    Code = ErrorCode.RequiredPropertyNotProvided,
                    Message = message
                });
            } else {
                apiError.Errors.Add(new ApiErrorMessage {
                    Code = ErrorCode.PropertyNotValid,
                    Message = message
                });
            }
        }
        return Request.CreateResponse(HttpStatusCode.BadRequest, apiError);
    }
}

客户端代码：

public Contact Post(Contact contact)
{
    try
    {
        var handler = new HttpClientHandler { AllowAutoRedirect = true};
        using (var client = new HttpClient(handler))
        {
            client.BaseAddress = new Uri(APIServer);
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            client.DefaultRequestHeaders.Add("X-ApiKey", APIKey.ToString());
            var response = client.PostAsJsonAsync("v1/Contacts", contact).Result;
            if (response.IsSuccessStatusCode)
            {
                Log.DebugFormat("Post v1/Contacts => {0} ({1})", response.StatusCode, response.ReasonPhrase);
                var result = JsonConvert.DeserializeObject<Contact>(response.Content.ReadAsStringAsync().Result);
                // This object is null
            }
            else
            {
                Log.ErrorFormat("Post v1/Contacts => {0} ({1})", response.StatusCode, response.ReasonPhrase);    
                var result = JsonConvert.DeserializeObject<ApiMessageResponse>(
                        response.Content.ReadAsStringAsync().Result);                      
            }

        }
    }
    catch (Exception exception)
    {
        Log.Error(exception);
    }
    return null;
}

线鲨日志。

POST/v1/Contacts HTTP/1.1 （application/json）HTTP/1.1 201 已创建位置： http://api01.example.com/v1/Contacts/10135052

就是这样，据我所知，没有 GET（http://api01.example.com/v1/Contacts/10135052）。
