Enviar Una OTP En Un Número De Móvil Registrado Usando C #

En este artículo, aprenderá a enviar una contraseña de un solo uso [OTP] a un número de teléfono móvil registrado mediante C # y asp.net.

Paso 1

Primero cree una página web en su Visual Studio y diseñela. El diseño se da a continuación,

<asp:Panel ID="pnl1" runat="server">
  <table>
    <tr>
      <td>Enter Your Mobile Number:</td>
      <td>
        <asp:TextBox ID="txtmobileNo" runat="server"></asp:TextBox>
      </td>
    </tr>
    <tr>
      <td></td>
      <td>
        <asp:Button ID="btnsendOtp" runat="server" Text="Send OTP" OnClick="btnsendOtp_Click" />
      </td>
    </tr>
  </table>
</asp:Panel>
<asp:Panel ID="pnl2" runat="server" Visible="false">
  <table>
    <tr>
      <td>Enter Your OTP:</td>
      <td>
        <asp:TextBox ID="txtverifyMobileNO" runat="server"></asp:TextBox>
      </td>
    </tr>
    <tr>
      <td></td>
      <td>
        <asp:Button ID="btnverify" runat="server" Text="Verify" OnClick="btnverify_Click" />
      </td>
    </tr>
  </table>
</asp:Panel>

Paso 2

Agregue el espacio de nombres debajo en la página .cs,

using System.Data.SqlClient;
using System.Data;
using System.Net;
using System.Web.ClientServices;
using System.Collections.Specialized;
using System.Configuration;

Paso 3

Para enviar OTP necesita la clave API. Registre sus datos en el enlace de abajo para API KEY y obtenga 10 SMS gratis.

https://www.textlocal.in/

Etapa 4

Después de registrarse correctamente, vaya a la opción de configuración y haga clic en API Key para generar la clave API

Paso 5

Haga clic en crear clave API y no es necesario ingresar la dirección IP y las notas, simplemente guárdelo.

Paso 6

Escriba el siguiente código en btnOtp_click 

protected void btnsendOtp_Click(object sender, EventArgs e) {
    pnl1.Visible = false;
    pnl2.Visible = true;
    Random random = new Random();
    int value = random.Next(1001, 9999);
    string destinationaddress = "+91" + txtmobileNo.Text;
    string message = "Your OTP is " + value + "(Send by R.R.Research and development founder is Ramesh Chandra)";
    string message1 = HttpUtility.UrlEncode(message);
    using(var wb = new WebClient()) {
        byte[] response = wb.UploadValues("https://api.textlocal.in/send/", new NameValueCollection() {
            {
                "apikey",
                "here is enter your API Key"
            }, {
                "numbers",
                destinationaddress
            }, {
                "message",
                message1
            }, {
                "sender",
                "TXTLCL"
            }
        });
        string result = System.Text.Encoding.UTF8.GetString(response);
        Session["OTP"] = value;
    }
}

Paso 6

Verifique su OTP. Escriba el siguiente código en el botón de verificación.

protected void btnverify_Click(object sender, EventArgs e) {
    if (txtverifyMobileNO.Text == Session["OTP"].ToString()) {
        pnl2.Visible = false;
        ScriptManager.RegisterStartupScript(this, typeof(string), "Message", "confirm('Your Mobilenumber has been verify sccessfully.');", true);
    } else {
        ScriptManager.RegisterStartupScript(this, typeof(string), "Message", "confirm('Your OTP is not correct please enter correct OTP');", true);
        pnl2.Visible = true;
    }
}

Paso 7

Ahora ejecuta el proyecto.

Producción

Paso 8

Después de ingresar el número de teléfono móvil y hacer clic en enviar OTP, el primer panel será falso y el segundo panel será verdadero.

Paso 9

Ingrese OTP y haga clic en el botón verificar, obtendrá el siguiente mensaje.

"Su número de teléfono móvil ha sido verificado correctamente".

How to Run C/C++ in Sublime Text?

C and C++ are the most powerful programming language in the world. Most of the super fast and complex libraries and algorithms are written in C or C++. Most powerful Kernel programs are also written in C. So, there is no way to skip it.

In programming competitions, most programmers prefer to write code in C or C++. Tourist is considered the worlds top programming contestant of all ages who write code in C++.

During programming competitions, programmers prefer to use a lightweight editor to focus on coding and algorithm designing. VimSublime Text, and Notepad++ are the most common editors for us. Apart from the competition, many software developers and professionals love to use Sublime Text just because of its flexibility.

I have discussed the steps we need to complete in this blog post before running a C/C++ code in Sublime Text. We will take the inputs from an input file and print outputs to an output file without using freopen file related functions in C/C++.

Dicey Issues in C/C++

If you are familiar with C/C++then you must have come across some unusual things and if you haven’t, then you are about to. The below codes are checked twice before adding, so feel free to share this article with your friends. The following displays some of the issues:

  1. Using multiple variables in the print function
  2. Comparing Signed integer with unsigned integer
  3. Putting a semicolon at the end of the loop statement
  4. C preprocessor doesn’t need a semicolon
  5. Size of the string matters
  6. Macros and equations aren’t good friends
  7. Never compare Floating data type with double data type
  8. Arrays have a boundary
  9. Character constants are different from string literals
  10. Difference between single(=) and double(==) equal signs.

The below code generates no error since a print function can take any number of inputs but creates a mismatch with the variables. The print function is used to display characters, strings, integers, float, octal, and hexadecimal values onto the output screen. The format specifier is used to display the value of a variable.

  1. %d indicates Integer Format Specifier
  2. %f indicates Float Format Specifier
  3. %c indicates Character Format Specifier
  4. %s indicates String Format Specifier
  5. %u indicates Unsigned Integer Format Specifier
  6. %ld indicates Long Int Format Specifier

A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a non-negative integer in the range [0 to 4294967295]. The signed integer is represented in twos-complement notation. In the below code the signed integer will be converted to the maximum unsigned integer then compared with the unsigned integer.
