How to return access token as json result ?

Problem

How to return Access Token as json result ?

I work on asp.net core 2.2 from function below i generate access token

it is success generated as string but i need to generated as json

How to generate access token as json from function below ?

public string GenerateTokens(string userId)
{
var Claims = new Claim[]
{
new Claim(JwtRegisteredClaimNames.Sub,userId)
};
var signingkey = new
SymmetricSecurityKey(Encoding.UTF8.GetBytes("this is secret phrase"));
var SigningCredntials = new SigningCredentials(signingkey,
SecurityAlgorithms.HmacSha256);
var Jwt = new JwtSecurityToken();
var jsonu = new { id = userId };
Jwt.Payload["user"] = jsonu;
return new JwtSecurityTokenHandler().WriteToken(Jwt);
}

suppose i have more data return i need to return it

suupose i have two object i need to convert to json

can i do more ok (token),ok(result1)

public IActionResult PostUserLogins([FromBody] Users user)
{
string JsonResults = "";
int LoginStatus = _SecurityService.PostUserLogin(user.UserName, user.Password, out DataTable dtBranches, out string errorMessage);
if (LoginStatus == 0)
{
dynamic request_status = new JObject();
request_status.Status = "succeeded";
request_status.Code = 0;
request_status.Message = errorMessage;
// get list of Branches
List branchesList = new List();
for (int i = 0; i < dtBranches.Rows.Count; i++)
{
Branches branch = new Branches();
branch.BranchCode = Utilities.ObjectConverter.ConvertToInteger(dtBranches.Rows[i]["BranchCode"]);
branch.BranchName = Utilities.ObjectConverter.ConvertToString(dtBranches.Rows[i]["BranchAraName"]);
branchesList.Add(branch);
}
dynamic user_data = new JObject();
user_data.UserName = user.UserName;
user_data.LoginTime = DateTime.Now.ToString();
//user_data.Branches = new JArray(branchesList);
user_data.Branches = JToken.FromObject(branchesList);
dynamic AccessToken = _SecurityService.GenerateTokens(user.UserName, out object jwtcontent);
JObject Ocontent = (JObject)JToken.FromObject(jwtcontent);
dynamic AccessTokenPayload = new JObject();
AccessTokenPayload.payloaddata = Ocontent;
dynamic ResultSuccessLogin = new JObject();
ResultSuccessLogin.request_status = request_status;
ResultSuccessLogin.AccessToken = AccessToken;
//ResultSuccessLogin.payloaddata = AccessTokenPayload;
ResultSuccessLogin.user_data = user_data;
JsonResults = JsonConvert.SerializeObject(ResultSuccessLogin);
}
ublic string GenerateTokens(string userId,out object jwtcontent)
{
jwtcontent = new object();
// this is secret phrase
var Claims = new Claim[]
{
new Claim(JwtRegisteredClaimNames.Sub,userId)
};
var signingkey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("Engaz@2012"));
var SigningCredntials = new SigningCredentials(signingkey, SecurityAlgorithms.HmacSha256);
var Jwt = new JwtSecurityToken();
var jsonu = new { id = userId };
Jwt.Payload["user"] = jsonu;
jwtcontent = Jwt;
return new JwtSecurityTokenHandler().WriteToken(Jwt);
}

Hello Ahmed,

If you have multiple data return in API then can you use below example

public IActionResult PostUserLogins([FromBody] Users user)
{
...
...
var result = new { result1 = value1, result2 = value2 };
return Ok(result);
}

let me know if you have needed any other help.

Thanks

Hey, Use below libraries to decode the jwt token: https://github.com/jwt-dotnet/jwt
