Cognitive Face API返回Web应用程序没有结果 [英] Cognitive Face API returning No result from Web Application

问题描述

Hi Team，

我正在使用Microsoft Cognitive Face API实现人脸检测以验证此人并登录该应用程序。

I am using the Microsoft Cognitive Face API for implementing the Face Detection to Authenticate the person and login to the application.

为此，我正在创建一个PersonGroup并添加Person，然后添加Person of Face。培训人员小组等。

For that, I am creating a PersonGroup and add the Person and then Face of Person. Train Person group and so on.

我为此创建了一个WPF应用程序，一切正常。但实际的要求是我想在MVC Web应用程序中实现它。我在MVC Web应用程序中编写了相同的代码。

I have created a WPF application for this and everything works fine there. But the actual requirement is that I want to implement it in MVC Web Application. I have written the same code in MVC Web Application.

但是API没有返回任何内容而只是挂在Http请求调用上。这是我写的代码。

But there API is not returning anything and just hanged at the Http request call. Here is the code what I have written.

public class HttpClientHelper
    {
        HttpClient httpClient = new HttpClient();

        private const string subscriptionKey = "XXXXXXXXXXXXXXXXXXXXXXXXXX";

        private const string faceEndpoint = "https://southeastasia.api.cognitive.microsoft.com/face/v1.0/";

        public HttpClientHelper()
        {
            httpClient.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", subscriptionKey);
            httpClient.BaseAddress = new Uri(faceEndpoint);
        }

        public async Task<T> GetAsync<T>(string url)
        {
            var response = await httpClient.GetAsync(url);
            string contentString = await response.Content.ReadAsStringAsync();
            return JsonConvert.DeserializeObject<T>(contentString);
        }
    }


public static async Task CreatePersonGroup(UserGroup userGroup)
        {
            bool isGroupExists = false;
            PersonGroup personGroup;

            try
            {
                HttpClientHelper httpClientHelper = new HttpClientHelper();
                var response = httpClientHelper.GetAsync<PersonGroup>(string.Format("persongroups/{0}", userGroup.UserGroupId)).Result;

                personGroup = await faceClient.PersonGroup.GetAsync(userGroup.UserGroupId);
                userGroup.UserGroupId = personGroup.PersonGroupId;
                isGroupExists = true;
            }
            catch (APIErrorException ex)
            {
                if (ex.Body.Error.Code == "PersonGroupNotFound")
                    isGroupExists = false;
            }

            if (isGroupExists == false)
            {
                await faceClient.PersonGroup.CreateAsync(userGroup.UserGroupId, userGroup.Name);
            }
        }

它只是挂在httpClient上。 GetAsync（）方法调用并没有提前。而相同的东西在控制台应用程序和WPF应用程序中完全正常。 

It just gets hanged at httpClient.GetAsync() method call and does not move ahead. Whereas the same stuff works perfectly fine in a Console application and WPF Application. 

请帮助我。 

Kindly do help me. 

仅用于更新，当我从Web应用程序进行调用并在"度量标准"下监视它时在Azure门户中可用。它显示了"客户端错误"下的计数。当我从控制台应用程序拨打电话时，它会转到"成功
通话"。

Just For an update, When I am making a call from Web Application and Monitor it under "Metrics" available in Azure portal. It shows me the count under "Client Errors". And When I make a call from Console Application it goes to "Successful Calls".

那么请你帮我一下我该怎么办？检查此客户端错误是什么？如何获得有关此客户端错误的更多详细信息？

So can you please help me how can I check what this Client Error is? And How Can I get more details about this Client Error?
