找不到Microsoft Face API 1.0错误资源

Question

我正在使用Microsoft Azure认知服务进行人脸识别项目。不太确定为什么我不能更正自己的JSON格式错误的语法，我以为6个月前就确定了这一点。我想创建一个组名，所以我调用“ Person Group API”，每次我遵循MS示例时，我的代码都会出错，但是在API测试控制台中，这没有问题，这是我从MS网站借来的代码示例：

 { "error": { "code": "ResourceNotFound", "message": "The requested resource was not found." } }

以及在控制台模式下运行的代码：

static async void CreateGroup()
        {
            string key1 = "YourKey"; 
             // azure the one should work 
            var client = new HttpClient();
            var queryString = HttpUtility.ParseQueryString(string.Empty);

            // Request headers
           client.DefaultRequestHeaders.Add
           ("Ocp-Apim-Subscription-Key", key1);

        var uri = "https://westus.api.cognitive.microsoft.com/face/v1.0/
        persongroups/{personGroupId}?" + queryString;

        HttpResponseMessage response;

        // Request body
        string groupname = "myfriends";

        string body = "{\"name\":\"" + groupname + ","+ "\"}";
        // Request body
        using (var content = new StringContent
        (body, Encoding.UTF8, "application/json"))
        {

            await client.PostAsync(uri, content)
                .ContinueWith(async responseTask =>
                {
                    var responseBody = await responseTask.Result
                    .Content.ReadAsStringAsync();
                    Console.ForegroundColor = ConsoleColor.Yellow;
                    Console.WriteLine("Response: {0}", responseBody);
                    Console.WriteLine("");

                    Console.WriteLine("Group Created.... ");
                    Console.WriteLine("Hit ENTER to exit...");
                    Console.ReadKey();
                });

            response = await client.PutAsync(uri, content);
            Console.WriteLine("what is this {0}", response.ToString());
            Console.ReadKey();

        }// end of using statement 


    }// end of CreateGroup
    #endregion

我想在这里，但我认为它的JSON再次格式错误，而我只是不知道这次我又在做什么错。根据站点，我需要发送给ms的字段名称'name' : 'userData'是可选的。

面对类似的问题，在uri中添加“ / detect”后，问题已解决。见下面

var uri = "https://westus.api.cognitive.microsoft.com/face/v1.0/detect

另外，请确保订阅密钥有效。
