I was able to get this working with `kiota`
kiota generate -d "{SERVER_URL}/webapi//swagger/docs/3" -o ".\api-v3" -l CSharp
As for the `IAccessTokenProvider`,
public async Task<string> GetToken(bool invalidateCache = false)
{
if (invalidateCache || this.expiresAt < DateTime.Now)
{
this.accessToken = "";
this.expiresAt = DateTime.MinValue;
string body;
using HttpRequestMessage request = new(HttpMethod.Post, new Uri(this.baseUri, "oauth2/token"))
{
Content = new StringContent("grant_type=client_credentials")
};
request.Content.Headers.ContentType = new("application/x-www-form-urlencoded");
string authPlain = $"{this.apiKey}:{this.apiSecret}";
byte[] authBytes = Encoding.GetEncoding("ISO-8859-1").GetBytes(authPlain);
string authEncoded = Convert.ToBase64String(authBytes);
request.Headers.Add("Authorization", $"Basic {authEncoded}");
using HttpResponseMessage response = await this.httpClient.SendAsync(request);
response.EnsureSuccessStatusCode();
body = await response.Content.ReadAsStringAsync();
string accessToken;
string tokenType;
int expiresIn;
try
{
JsonNode root = JsonNode.Parse(body)
?? throw new JsonException("Body is null");
accessToken = root["access_token"].GetValue<string>();
tokenType = root["token_type"].GetValue<string>();
expiresIn = root["expires_in"].GetValue<int>();
}
catch (JsonException)
{
throw;
}
catch (Exception ex)
{
throw new JsonException($"Error parsing JSON: {ex.Message}");
}
if (tokenType != "bearer")
throw new NotSupportedException($"Unexpected token type: {tokenType}");
this.accessToken = accessToken;
this.expiresAt = DateTime.Now.AddSeconds(expiresIn - 10);
}
return this.accessToken;
}
And this works wonderfully for v1 and v2 as well.
