标签: javascript php jquery ajax

当调用AJAX时,我总是会遇到这些错误:
net :: ERR_EMPTY_RESPONSE或net :: ERR_CONNECTION_RESET

我还尝试过不同的浏览器(Chrome和Edge),但它只适用于localhost。

感谢您的所有帮助和支持。

我的PHP代码(register.php):

    require_once 'mysql_conn.php';
    // username and password sent from form 
    $myUsername = mysqli_real_escape_string($db,$_POST['username']);
    $myPassword = mysqli_real_escape_string($db,$_POST['password']); 
    $myRepPassword = mysqli_real_escape_string($db,$_POST['rep_password']); 

    if($myPassword == $myRepPassword && strlen($myUsername) >= 3 && strlen($myPassword) >= 8)
    {
        $userCheck = "SELECT id FROM users WHERE username = '$myUsername'";
        $result = mysqli_query($db,$userCheck);
        $count = mysqli_num_rows($result);


        if($count > 0)
        {
           echo "This user already exists";
        }
        else
        {
            $sql = "INSERT INTO users (username, password) VALUES ('$myUsername', '$myPassword')";

            if ($db->query($sql) === TRUE) {
                echo "New record created successfully";
            } else {
                echo "Error: " . $sql . "<br>" . $db->error;
            }
            $db->close();
        }            
    }  
    else
    {
        echo "Please check the values you inserted";
    } 

和AJAX电话:

        $(function () {
            $('form').submit(function (e) {                      

                e.preventDefault();

                $.ajax({
                    type: 'POST',
                    url: 'register.php',                
                    data: {username:username, password:password, rep_password:rep_password},
                    success: function (data) {
                        errorHandling(data);
                    }
                });
            });
        });

我不知道怎么做,但我通过删除并重新创建register.php文件解决了这个问题
