How to get Auth code in api call post on ruby on rails app from wix api website?

I'm trying to developing a dashboard website for a wix application and I need to connect the website to the wix application.
I have a problem with an api (post) call. I have to fill in several information including the auth code that I don't know where to find.
Here is an image to illustrate the process :
I don't really know what is the wix app marker install, but for the authorization request I did this
$url_oauth = "https://www.wix.com/oauth/access"
response = RestClient::Request.execute(url: $url_oauth, method: :post, body:{grant_type: "authorization_code",client_id:"APP_ID", client_secret:"Secret_key", code:"{Can not find what is this value}"})
#data = JSON.parse(response)
render json: response
Here is the documentation :
Could you help how and where to find this Auth code ?
You will need to make an intermediate web service that will accept webhooks from WIX.
I'll show you the example of C# ASP.Net Core.
STEP 1:
We are waiting for a token from WIX and if it is received, we make a redirect.
private const string AppID = "";
private const string ApiKey = "";
private const string UrlAccess = "https://www.wix.com/oauth/access";
HttpGet("WaitToken")]
public ActionResult GetToken([FromQuery] string token = "")
{
try
{
if (string.IsNullOrWhiteSpace(token))
{
string message = "Your message";
ModelState.AddModelError("TokenNotCorrect", message);
return BadRequest(ModelState);
}
string paramUrl = #"https://your web service/OAuth/api/check/WaitAuthCode";
string urlRedirect = $#"https://www.wix.com/installer/install?token={token}&appId={AppID}&redirectUrl={paramUrl}";
return RedirectPermanent(urlRedirect);
}
catch (WebException ex)
{
ModelState.AddModelError("GetTokenException", ex.Message);
return BadRequest(ModelState);
}
}
STEP 2:
We are waiting for the Auth Code to be received, provided that the user has confirmed the installation of the application.
[HttpGet("WaitAuthCode")]
public async Task<ActionResult> GetAuthCodeAsync([FromQuery] string code = "", string state = "", string instanceId = "")
{
try
{
if (string.IsNullOrWhiteSpace(code))
{
string message = "your message";
ModelState.AddModelError("AuthCodeNotCorrect", message);
return BadRequest(ModelState);
}
var token = new Token(code);
if (!GetAccessToken(ref token))
return BadRequest("your message RefreshToken");
var tokenBase = new TokenBase
{
AppID = instanceId,
Token = token.RefreshToken
};
db.Tokens.Add(tokenBase);
if(await db.SaveChangesAsync() == 0)
return BadRequest("your message");
string urlRedirect = $"https://www.wix.com/installer/token-received?access_token={token.AccessToken}";
return RedirectPermanent(urlRedirect);
}
catch (WebException ex)
{
ModelState.AddModelError("GetAuthCodeException", ex.Message);
return BadRequest(ModelState);
}
}
The AuthCode is valid for 10 minutes, we send a request to receive a Refresh Token. This token must be kept at home, as it will be required in the future to obtain an Access Token.
private bool GetAccessToken(ref Token token)
{
try
{
string json = JsonConvert.SerializeObject(token, Formatting.Indented);
var client = new RestClient(UrlAccess);
var request = new RestRequest();
request.Method = Method.POST;
request.AddHeader("Content-Type", "application/json");
request.AddParameter(string.Empty, json, "application/json", ParameterType.RequestBody);
var response = client.Post(request);
if (response == null)
return false;
token = JsonConvert.DeserializeObject<Token>(response.Content);
if (string.IsNullOrWhiteSpace(token.RefreshToken))
return false;
return !string.IsNullOrWhiteSpace(token.AccessToken);
}
catch (Exception ex)
{
return false;
}
}
Getting an Access Token from a client application:
[HttpGet("WaitAccessToken")]
public async Task<ActionResult<string>> GetAccessToken([FromQuery] string instance = "", string apiKey = "")
{
string message;
var tokenBase = await db.Tokens.FirstOrDefaultAsync(x => x.AppID == instance);
if (tokenBase == null)
{
message = "Your message";
ModelState.AddModelError("AppIdNotFound", message);
return NotFound(ModelState);
}
var token = new Token
{
GrantType = "refresh_token",
RefreshToken = tokenBase.Token
};
if (!GetAccessToken(ref token))
{
message = $"Your message";
ModelState.AddModelError("NotCorrectAccessToken", message);
return BadRequest(ModelState);
}
return new ObjectResult(token.AccessToken);
}
Model Token:
public class Token
{
public Token() { }
public Token(string code) { Code = code; }
[JsonProperty("grant_type")]
public string GrantType { get; set; } = "authorization_code";
[JsonProperty("client_id")]
public string ClientID { get; set; } = "";
[JsonProperty("client_secret")]
public string ClientSecret { get; set; } = "";
[JsonProperty("code")]
public string Code { get; set; }
[JsonProperty("refresh_token", NullValueHandling = NullValueHandling.Ignore)]
public string RefreshToken { get; set; }
[JsonProperty("access_token", NullValueHandling = NullValueHandling.Ignore)]
public string AccessToken { get; set; }
}
Model Instance:
public class Instance
{
[JsonProperty("instanceId")]
public string InstanceId { get; set; }
[JsonProperty("appDefId")]
public string AppDefId { get; set; }
[JsonProperty("signDate")]
public DateTime SignDate { get; set; }
[JsonProperty("uid")]
public string Uid { get; set; }
[JsonProperty("permissions")]
public string Permissions { get; set; }
[JsonProperty("demoMode")]
public bool DemoMode { get; set; }
[JsonProperty("siteOwnerId")]
public string SiteOwnerId { get; set; }
[JsonProperty("siteMemberId")]
public string SiteMemberId { get; set; }
[JsonProperty("expirationDate")]
public DateTime ExpirationDate { get; set; }
[JsonProperty("loginAccountId")]
public string LoginAccountId { get; set; }
}
Don't forget that to get an Access Token, you will need the application ID on the site where it is installed.
[HttpGet("WixInfo")]
public ActionResult GetWixInfo([FromQuery] string instance = "")
{
try
{
string message;
var base64 = instance.Split(".");
if (base64.Length != 2)
{
message = "Your message";
ModelState.AddModelError("InstanceNotCorrect", message);
return BadRequest(ModelState);
}
var base64EncodedBytes = Convert.FromBase64String(base64[1]);
string json = Encoding.Default.GetString(base64EncodedBytes);
var info = JsonConvert.DeserializeObject<Instance>(json);
message = $"Your message.AppID: {info.InstanceId}";
return Ok(message);
}
catch (Exception ex)
{
ModelState.AddModelError("GetWixInfoException", ex.Message);
return BadRequest(ModelState);
}
}
When a WIX application is launched by a user, you can get the ID of the running application.

how to save a picker value to the web api using the mvvm properties in the command?

I have a xamarin forms application and would like to save some values ​​that I got from the picker via the web api. The objective is to save this value as well as the other properties in the web api that is linked to the sql server database, but I have issues in how to reference the value selected in the picker through mvvm. I can load the data from the picker but I just don't know how to save these values ​​by referencing the picker in mvvm.
UsuarioModel Class
This is the model class, it has the CodPerfil property which is the foreign key that should be stored in my web api database and must correspond to the value that will be selected in the picker.
public class UsuarioModel

I would be grateful if someone could help me.
thanks for the tips. what happened was that the viewmodel that was being binded in the Register.xaml.cs class was not the one that contained the Register command. I solve the 'problem' by replacing the viewmodel and it worked!

public RegisterPage()

Xamarin Forms consuming Web Service

I'm new in mobile apps and now developing an app with xamarin forms. There is a website which i developed with django (sqlite3 db), and now i'am trying to consume data from it and display in my mobile app in listvew. Any thoughts how to achieve it. I've tried this but it doesn't work. Should i use rest api?
public class LandingViewModel : INotifyPropertyChanged
{
private List<Dishes> _menuList { set; get; }
public List<Dishes> MenuList
{
get
{
return _menuList;
}
set
{
if(value != _menuList)
{
_menuList = value;
NotifyPropertyChanged();
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected void NotifyPropertyChanged([CallerMemberName] string propertyName = "")
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
public LandingViewModel()
{
GetDataAsync();
}
private async void GetDataAsync()
{
HttpClient client = new HttpClient();
var response = await client.GetAsync("https://mysite.ru/project/");
if (response.IsSuccessStatusCode)
{
var content = await response.Content.ReadAsStringAsync();
var menu = JsonConvert.DeserializeObject<List<Dishes>>(content);
MenuList = new List<Dishes>(menu);
}
}
models:
public class Dishes
{
public int id { get; set; }
public string description { get; set; }
public string image { get; set; }
public DateTime published { get; set; }
}
my database in django:
operations = [
migrations.CreateModel(
name='Post',
fields=[
('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
('description', models.TextField(blank=True)),
('image', models.ImageField(blank=True, upload_to='pictures/')),
('published', models.DateTimeField(verbose_name='publishing date')),
],
),
]
i solved the problem
in postgresql database allowed remote connection: in postgresql.conf replaced line listen_addresses = 'localhost' with listen_addresses = '*'
allowed tcp\ip connection on port 5432
in my web api established connection width db
NpgsqlConnection connection;
public string _name;
public string _description;
public string _image;
private readonly MenuContext _context;
public MenuController(MenuContext context)
{
_context = context;
string connectionString = "Server=server; Port=5432; User Id=user;

}
}
// GET: api/Menu

I am getting a reasonable loginResult. And PasswordSignInAsync method returns with success. At that point I conclude the sign in process is OK. But after when I check User.Identity. I see it is null. Same is valid for the SignInAsync method.All I wanna do is sign-in the user only using the remote services. Thank you all..
I solved the problem as given below:
Change the httpost login method in AccountController of Web.Mvc application as below
[HttpPost]
[UnitOfWork]
public virtual async Task<JsonResult> Login(LoginViewModel loginModel, string returnUrl = "", string returnUrlHash = "")
{
var claims = GetClaims(loginModel.UsernameOrEmailAddress, loginModel.Password);
if (claims == null)//giriş yapılamadı
{
return Json(new AjaxResponse { TargetUrl = "" });
}
else
{
var identity = new ClaimsIdentity(CookieAuthenticationDefaults.AuthenticationScheme, ClaimTypes.Name,
ClaimTypes.Role);
foreach (var claim in claims)
{
identity.AddClaim(new Claim(claim.type, claim.value));
}
//AbpSession.UserId=18;
//// Authenticate using the identity
//var principal = new ClaimsPrincipal(identity);
//await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal, new AuthenticationProperties { IsPersistent = true });
//bool chk = User.Identity.IsAuthenticated;
////bool bak = User.Identity.IsAuthenticated;
//bool bak2 = User.IsInRole("Admin");
//return RedirectToAction("Index", "Home");
await _signInManager.SignInAsync(identity, loginModel.RememberMe);
await UnitOfWorkManager.Current.SaveChangesAsync();
bool bak = User.Identity.IsAuthenticated;
var bakl = AbpSession.UserId;
}
returnUrl = NormalizeReturnUrl(returnUrl);
if (!string.IsNullOrWhiteSpace(returnUrlHash))
{
returnUrl = returnUrl + returnUrlHash;
}
return Json(new AjaxResponse { TargetUrl = returnUrl });
}
Create GetClaims method in AccountController of Web.Mvc application
protected List<ClaimRootObject> GetClaims(string UserName, string Password)
{
using (var client = new HttpClient())
{
string reqString = "http://localhost:21021/api/" + "TokenAuth/GetClaims/GetClaims?UserName=" + UserName + "&password=" + Password + "&TenantName=Default";
//string reqString = "http://localhost:81/api/TokenAuth/GetClaims/GetClaims?UserName=admin&password=123qwe&TenantName=TSEDergi";
HttpResponseMessage response = client.GetAsync(reqString).Result; // Blocking call!
if (response.IsSuccessStatusCode)
{
// Get the response
var JsonString = response.Content.ReadAsStringAsync();
// Deserialise the data (include the Newtonsoft JSON Nuget package if you don't already have it)
//List<Claim> deserialized = JsonConvert.DeserializeObject<List<Claim>>(JsonString.Result);
List<ClaimRootObject> deserialized = JsonConvert.DeserializeObject<List<ClaimRootObject>>(JsonString.Result);
if (deserialized != null)
{
return deserialized;
}
}
else
{
}
}
return null;
}
Create the required objects
public class ClaimRootObject
{
public string issuer { get; set; }
public string originalIssuer { get; set; }
public Properties properties { get; set; }
public Subject subject { get; set; }
public string type { get; set; }
public string value { get; set; }
public string valueType { get; set; }
}
public class Properties
{
}
public class Subject
{
public string authenticationType { get; set; }
public bool isAuthenticated { get; set; }
public object actor { get; set; }
public object bootstrapContext { get; set; }
public List claims { get; set; }
public object label { get; set; }
public string name { get; set; }
public string nameClaimType { get; set; }
public string roleClaimType { get; set; }
}
And last step, modify your startup class of Web.Mvc project to enable cookie authentication.
public IServiceProvider ConfigureServices(IServiceCollection services)
{
// MVC
services.AddMvc(
options => options.Filters.Add(new AutoValidateAntiforgeryTokenAttribute())
);
#region cookieAuthentication
services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie();
#endregion cookieAuthentication
IdentityRegistrar.Register(services);
AuthConfigurer.Configure(services, _appConfiguration);
services.AddScoped();
services.AddSignalR();
// Configure Abp and Dependency Injection
return services.AddAbp(
// Configure Log4Net logging
options => options.IocManager.IocContainer.AddFacility(
f => f.UseAbpLog4Net().WithConfig("log4net.config")
)
);
}
That's all. Then you can log in a user into the application using only remote services..

Prism Event Aggregator Not Working With Async/Await

I am working with prism in a client server app with sql server. I have a loading screen after login screen in which I've fetch the main data in async task for main windows and publish it and subscribe in main windows like customers, Users and etc. But the problem is that subscriber not updated. But If I sign out and sign in again then subscriber updated.
Subscriber not updated first time.
Here is the code of loading screen
public class StartPageViewModel : ViewModelBase
{
private readonly IUnitOfWork _unitOfWork;
private readonly IEventAggregator _eventAggregator;
private readonly IRegionManager _regionManager;
public List<Customer> Customers { get; set; }
private List<Models.User> Users { get; set; }
private List<Invoice> Invoices { get; set; }
public List<Vehicle> Vehicles { get; set; }
public List<Tax> Taxes { get; set; }
private Models.User _user;
private object _userId;
public StartPageViewModel(IRegionManager regionManager, Models.User user,
IUnitOfWork unitOfWork, IEventAggregator eventAggregator)
{
_regionManager = regionManager;
_user = user;
_unitOfWork = unitOfWork;
_eventAggregator = eventAggregator;
Customers = new List<Customer>();
Users = new List<Models.User>();
Invoices = new List<Invoice>();
Vehicles = new List<Vehicle>();
Taxes = new List<Tax>();
}
[OnCommand("InitializeStartPage")]
public async void InitializeStartPage()
{
if (!InternetCs.IsConnectedToInternet())
_regionManager.RequestNavigate(RegionNames.ShellRegion, "InternetConnection");
else
{
await Task.WhenAll(CheckUser(), Preloading()).ContinueWith(async(t, _) =>
{
_eventAggregator.GetEvent<AllCustomersEvent>().Publish(Customers);
_eventAggregator.GetEvent<AllInvoicesEvent>().Publish(Invoices);
_eventAggregator.GetEvent<CurrentUserEvent>().Publish(_user);
_eventAggregator.GetEvent<AllUsersEvent>().Publish(Users);
_eventAggregator.GetEvent<AllVehiclesEvent>().Publish(Vehicles);
_eventAggregator.GetEvent<AllTaxesEvent>().Publish(Taxes);
if (_user != null && _user.Status)
{
_user.LastLogin = DateTime.Now;
_user.LoginStatus = true;
_unitOfWork.UserRepository.Update(_user);
await _unitOfWork.SaveAsync();
_regionManager.RequestNavigate(RegionNames.MainContentRegion, "Home");
_regionManager.RequestNavigate(RegionNames.ShellRegion, "MainWindow");
}
else
{
_regionManager.RequestNavigate(RegionNames.ShellRegion, "LoginWindow");
}
}, null, TaskScheduler.FromCurrentSynchronizationContext());
}
}
private async Task<Models.User> CheckUser()
{
IsoStorage.Instance.TryGetValue("UserId", out _userId);
_user = await _unitOfWork.UserRepository.GetAsync((int)_userId);
return _user;
}
private async Task Preloading()
{
Customers = await _unitOfWork.CustomerRepository.GetAsync();
Invoices = await _unitOfWork.InvoiceRepository.GetAsync();
Users = await _unitOfWork.UserRepository.GetAsync();
Vehicles = await _unitOfWork.VehicleRepository.GetAsync();
Taxes = await _unitOfWork.TaxRepository.GetAsync();
}
}
and here is example subscriber
public AdminProfileViewModel(IEventAggregator eventAggregator)
{
Users = new List<Models.User>();
eventAggregator.GetEvent<AllUsersEvent>().Subscribe(AdminAllUsers, ThreadOption.PublisherThread);
}
private void AdminAllUsers(List<Models.User> obj)
{
Users = obj;
}
