Login enters directly via google

Question

Good morning! I used the google login API on a website page. It takes the information and works correctly, however, even without clicking the button, it already runs the js of google directly, without making it possible somehow to do the "singOut" of the system because whenever I go to the login page, it already automatically picks up the information and goes to the redirect page. Follow the code from the login page

<div class="g-signin2" data-onsuccess="onSignIn" data-theme="dark" style="width: 350px"></div>

                <script>
                    function onSignIn(googleUser) {
                        var profile = googleUser.getBasicProfile();
                        var userID = profile.getId();
                        var userName = profile.getName();
                        var userPicture = profile.getImageUrl();
                        var userEmail = profile.getEmail();
                        var userToken = googleUser.getAuthResponse().id_token;

                        //document.getElementById('msg').innerHTML = userEmail;
                        if(userEmail !== ''){
                            var dados = {
                                userID:userID,
                                userName:userName,
                                userPicture:userPicture,
                                userEmail:userEmail
                            };
                            $.post('validarLoginGoogle.php', dados, function(retorna){
                                    if(retorna=="1"){
                                            window.location.href = "http://calangoeventos.eu5.net/telas/telaInicial.php";
                                    }
                                    }else{
                                            window.location.href = "http://calangoeventos.eu5.net/telas/complementoCadastro.php";
                                    }
                            });
                        }
                    }
</script>

The purpose of the above code is to redirect the user to the home page if he has already accessed before and if not, redirect to the registration add-on screen And the code of my validarLoginGoogle.php

<?php
session_start();

include_once("../funcoes/integracaoBanco.php");
$email = filter_input(INPUT_POST, 'userEmail', FILTER_SANITIZE_STRING);
$name = filter_input(INPUT_POST, 'userName', FILTER_SANITIZE_STRING);

$result_usuario = "SELECT * FROM Usuario WHERE email='$email'";
$resultado_usuario = mysqli_query($conexao, $result_usuario);

//Econtrado usuario com esse e-mail
if(($resultado_usuario) AND ($resultado_usuario->num_rows != 0)){
        $user = mysqli_fetch_assoc($resultado_usuario);
        $_SESSION['usuarioLogado'] = $user;
        $result = 1;
    echo(json_encode($result));
}else{//Nenhum usuário encontrado
    $result = 2;
    echo(json_encode($result));
}

Here you are doing a validation that if Google data is validated and returns 1 goes to the

telaInicial.php( window.location.href = "http://calangoeventos.eu5.net/telas/telaInicial.php")

Do the validation by returning to the place you need, it’s quite simple

$.post('validarLoginGoogle.php', dados, function(retorna){
 if(retorna=="1"){
     window.location.href = "http://calangoeventos.eu5.net/telas/telaInicial.php";
 }else{
    window.location.href = "http://calangoeventos.eu5.net/telas/complementoCadastro.php";
   }
});

I also saw an error here, which may hinder its validation

$.post('validarLoginGoogle.php', dados, function(retorna){
                                    if(retorna=="1"){
                                            window.location.href = "http://calangoeventos.eu5.net/telas/telaInicial.php";
                                    }
                                    }else{
                                            window.location.href = "http://calangoeventos.eu5.net/telas/complementoCadastro.php";
                                    }
                            });

On line 4 there is a closure that in the case closes the if validation, not making it possible to pass the validation pro else
