Вы можете посмотреть следующий фрагмент кода, который я тестировал на портале azure, Azure Function V2:
#r "Newtonsoft.Json"
using Newtonsoft.Json;
using System.Net;
using System.Net.Http.Headers;
public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
try
{
//Parse query parameter
log.LogInformation("C# HTTP trigger function processed a request.");
//Read Request Body
var content = await new StreamReader(req.Body).ReadToEndAsync();
//Extract Request Body and Parse To Class
UserAuthentication objUserInfo = JsonConvert.DeserializeObject<UserAuthentication>(content);
//Message Container
dynamic validationMessage;
//Validate required param
if (string.IsNullOrEmpty(objUserInfo.UserName.Trim()))
{
validationMessage = new OkObjectResult("User name is required!");
return (IActionResult)validationMessage;
}
if (string.IsNullOrEmpty(objUserInfo.Password.Trim()))
{
validationMessage = new OkObjectResult("Password is required!");
return (IActionResult)validationMessage;
}
// Authentication Token Request format
string tokenUrl = $"https://login.microsoftonline.com/common/oauth2/token";
var tokenRequest = new HttpRequestMessage(HttpMethod.Post, tokenUrl);
tokenRequest.Content = new FormUrlEncodedContent(new Dictionary<string, string>
{
["grant_type"] = "password",
["client_id"] = "YourApplicationId",
["client_secret"] = "YourApplicationPassword",
["resource"] = "https://graph.microsoft.com",
["username"] = "" + objUserInfo.UserName + "",
["password"] = "" + objUserInfo.Password + ""
});
// Request For Token Endpoint
using (var _client = new HttpClient())
{
var tokenResponse = await _client.SendAsync(tokenRequest);
AccessTokenClass objAccessToken = JsonConvert.DeserializeObject<AccessTokenClass>(await tokenResponse.Content.ReadAsStringAsync());
// When Token Request Null
if (objAccessToken.access_token == null)
{
validationMessage = new OkObjectResult("Invalid Authentication! Please Check Your Credentials And Try Again!");
return (IActionResult)validationMessage;
}
else
{
return new OkObjectResult(objAccessToken.access_token);
}
}
}
catch (Exception ex)
{
validationMessage = new OkObjectResult("Sorry something went wrong! Please check your given information and try again! {0}" + ex.Message);
return (IActionResult)validationMessage;
}
}
Класс, который я использовал: UserAuthentication Class
public class UserAuthentication
{
public string UserName { get; set; }
public string Password { get; set; }
}
public class AzureFunctionCreateUserClass
{
public string access_token { get; set; }
public string expires_in { get; set; }
public string token_type { get; set; }
public string resource { get; set; }
}
Примечание: Это пример портала azure, который я написал для функции azure. Поэтому попытайтесь бежать туда.
Надеюсь, это поможет.
