Unknown web method When Making AJAX Call to WebMethod with ASP.NET












0















I'm kinda new to using AJAX call to a WebMethod. I feel my Web Method logic is but maybe someone could help out here. I do get an unknown web method error when I log the AJAX response to the console. Below is my Web method and AJAX call code.



$("#btnLogin").click(function () {
email = $("#txtEmailAddress").val();
password = $("#txtPassword").val();

//Create the login info object
var loginInfo = {};
//Set the object properties and value
loginInfo.Email = email;
loginInfo.Password = password;
//Make the ajax call
$.ajax({
type: "POST",
dataType: 'json',
url: '<%=ResolveUrl("identicate.aspx/ValidateUsersToken") %>',
data: '{loginInfo:' + JSON.stringify(loginInfo) + '}',
contentType: "application/json; charset=utf-8",
success: function (data) {
if (data.d == null || data.d == undefined)
{
alert("Username or password not correct = " + data.d);
console.log(data);
console.log(loginInfo);
console.log(this.url);
}
},
error: function (data) {
console.log(data);
console.log(loginInfo);
console.log(this.url);
alert(data.d);
}
});
});


And here's my web method



[WebMethod]
public static String ValidateUsersToken(iloginmodel loginInfo)
{
//Variable to hold the user email address
String email = string.Empty;
//Get the connection string from config file
String connectionString = iDbConfiguration.GetConnectionString();
//Create the command text
String commandText = "select Email, Password from VUser where Email = @Email & Password = @Password";
//Create database connection object and open it
using(SqlConnection loginConnection = new SqlConnection(connectionString))
{
//Set command paramters
SqlCommand loginCommand = new SqlCommand(commandText, loginConnection);
//Set command type to text
loginCommand.CommandType = System.Data.CommandType.Text;
//Add parameter to command
loginCommand.Parameters.AddWithValue("Email", loginInfo.Email);
loginCommand.Parameters.AddWithValue("@Password", loginInfo.Password);

//Open the database connection
try
{
loginConnection.Open();

SqlDataReader loginReader = loginCommand.ExecuteReader();
if(loginReader.HasRows)
{

HttpContext.Current.Response.Write(loginReader.ToString());

while (loginReader.Read())
{
if (loginReader.HasRows)
{
email = loginReader["Email"].ToString();
}
}
}
}
catch(SqlException sqlEx)
{
HttpContext.Current.Response.Write(sqlEx.Message);
}
finally
{
loginConnection.Close();
}

}
return email;
}

  • I have tried to reproduce your error but your code seem to work fine. Could you show what is getting logged inside your browser console.

  • Could you paste your <%@ Page diretive of your aspx page here.

  • It could be possible that the Page Directive at the top of the aspx page has been deleted accidentally. Please check.
