【问题描述】：
我创建了一个认知服务人脸 API，但我的端点似乎无法正常工作。它没有给出地址内的位置。这被列为我的端点：https://kbob.cognitiveservices.azure.com/

const string subscriptionKey = "xxxx_VALUE_HIDDEN_xxxx";
const string uriBase = "https://kbob.cognitiveservices.azure.com/";
async public Task<emotions> MakeAnalysisRequest(byte[] imageData)
{
HttpClient client = new HttpClient();
// Request headers.
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", subscriptionKey);
// Request parameters. A third optional parameter is "details".
string requestParameters = "?returnFaceAttributes=emotion";
// Assemble the URI for the REST API Call.
string uri = uriBase + requestParameters;
HttpResponseMessage response;
// Request body. Posts a locally stored JPEG image.
//byte[] byteData = GetImageAsByteArray(imageFilePath);
using (ByteArrayContent content = new ByteArrayContent(imageData))
{
// This example uses content type "application/octet-stream".
// The other content types you can use are "application/json" and "multipart/form-data".
content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
// Execute the REST API call.
response = await client.PostAsync(uri, content);
// Get the JSON response.
string contentString = await response.Content.ReadAsStringAsync();
// Display the JSON response.
Console.WriteLine("\nResponse:\n");
//Console.WriteLine(JsonPrettyPrint(contentString));
// For that you will need to add reference to System.Runtime.Serialization
var jsonReader = JsonReaderWriterFactory.CreateJsonReader(Encoding.UTF8.GetBytes(contentString), new System.Xml.XmlDictionaryReaderQuotas());
// For that you will need to add reference to System.Xml and System.Xml.Linq
var root = XElement.Load(jsonReader);
Console.WriteLine(root.XPathSelectElement("//faceAttributes").Value);
Console.WriteLine(root.XPathSelectElement("//faceAttributes/emotion").Value);
Console.WriteLine(root.XPathSelectElement("//faceAttributes/emotion/anger").Value);

emos.sadness = decimal.Parse(root.XPathSelectElement("//faceAttributes/emotion/sadness").Value);

return emos;
}
}
}

【问题讨论】：
-
“它没有给出地址中的位置”是什么意思。 ?您能否添加更多实施细节？
-
我被告知它应该是“northcentralus.cognitiveservices.azure.com/face。或类似的东西。
-
当我在 Visual Studio 中使用它时，它会抛出一个似乎与端点有关的错误。
-
添加您的实施细节，以便我们提供帮助。有两种类型的端点：一种使用区域名称，另一种使用您提到的子域。两者都有效，您只需要根据您的实施方式传递正确的信息
-
@NicolasR 我可以附在某处吗？\
