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
