I am developing an application that is a short version of a web system, this system was developed in PHP. For the application, I am developing in Xamarin Forms, however via web api I am trying to make the login screen, but when entering any login or password it is logging in, and this could not happen, should log in only when entering the saved user data in the database. Down with my code:
Loginpage.xaml.Cs
public partial class LoginPage : TabbedPage
{
public LoginPage()
{
InitializeComponent();
NavigationPage.SetHasNavigationBar(this, false);
}
protected async void BtnLogin_Clicked(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(emailEntry.Text))
{
await DisplayAlert("Erro", "Digite um nome de usuário válido", "Aceitar");
emailEntry.Focus();
return;
}
if (string.IsNullOrEmpty(senhaEntry.Text))
{
await DisplayAlert("Erro", "Digite uma senha", "Aceitar");
emailEntry.Focus();
return;
}
this.logar();
App.Current.MainPage = new MainPageRoot();
}
private async void logar()
{
waitActivityIndicator.IsRunning = true;
var loginRequest = new LoginRequest
{
Usuario = emailEntry.Text,
Senha = senhaEntry.Text,
};
var JsonRequest = JsonConvert.SerializeObject(loginRequest);
var httpContent = new StringContent(JsonRequest);
var resp = string.Empty;
try
{
var client = new HttpClient();
client.BaseAddress = new Uri("http://ativoproject.ebasesistemas.com.br");
var url = "http://ativoproject.ebasesistemas.com.br/login.php";
var result = await client.PostAsync(url, httpContent);
if (!result.IsSuccessStatusCode)
{
await DisplayAlert("Erro", "Usuario ou senha incorretos", "Aceitar");
waitActivityIndicator.IsRunning = false;
return;
}
resp = await result.Content.ReadAsStringAsync();
}
catch (Exception ex)
{
await DisplayAlert("Erro", ex.Message, "Aceitar");
waitActivityIndicator.IsRunning = false;
return;
}
var user = JsonConvert.DeserializeObject<Colaborador>(resp);
waitActivityIndicator.IsRunning = false;
await DisplayAlert("Bem vindo","vc esta logado", "Aceitar");
}
}
Collaborator.Cs
public class Colaborador
{
public int ColaboradorID { get; set; }
public string Nome { get; set; }
public string UserName { get; set; }
public string Password { get; set; }
public bool Inativo { get; set; }
}
Loginrequest.Cs
class LoginRequest
{
public string Usuario { get; set; }
public string Senha { get; set; }
}
And this here is the system link on the web: http://ativoproject.ebasesistemas.com.br
I sort of understood, because I’m still a beginner in this language, you could show me an example of what you’re saying applied in my context?

@Wpfan To show in your scenario, I would need to know the structure of the response you get from the webservice to treat what we would be expecting, but I’ll try to include an example in the answer.
