Microsoft Face API 1.0 Error Resource Not Found - azure

Question

I am working on a face recognition project with Microsoft Azure Cognitive services. Not quite sure why I am not able to correct my own JSON Malformed syntax I thought I nail this 6 months ago. I want to create a group name, so I call upon 'Person Group API' and everytime I follow MS example I get errors in my code however in the API testing Console no problems here is my code example borrow from MS site :
{ "error": { "code": "ResourceNotFound", "message": "The requested resource was not found." } }
and the code which is run in Console mode :
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
I am guess here but I think its my JSON is malformed again and I just don't know what I am doing wrong again this time. According to the site the field name that I require to send over to ms is 'name' : 'userData' is optional.

Answer 1

Faced the similar issue, after adding "/detect" in the uri the issue fixed.
See the below
var uri = "https://westus.api.cognitive.microsoft.com/face/v1.0/detect
Also make sure the subscription key is valid.

Your request url must specify a group ID in place of where you have {personGroupId}. Per the spec the group ID must be:
User-provided personGroupId as a string. The valid characters include
numbers, English letters in lower case, '-' and '_'. The maximum
length of the personGroupId is 64.
Furthermore, the http verb needs to PUT, whereas you've made a client.PostAsync request. So you'll need to change that to client.PutAsync.
Microsoft provides a client library for C# for the Face API where you can find working C# code.

In python, simply this worked for me.
