对于一个项目，我们必须创建一个基本的登录系统。我正在尝试使用 REST 来管理我的整个页面。现在我相信我在这里遗漏或误解了一些关键概念，但我多年来一直试图弄清楚如何做到这一点。本练习不允许使用库，因此我无法使用 JQuery。
所以这是我的问题：我有一个 .js 文件，用于检查用户名长度和密码长度等......在这个 .js 文件中，我还有一个 ajax 函数，它将用户名和电子邮件发送到 PHP 以验证是否存在已经是使用 SQL 且具有该电子邮件或用户名的现有用户。
function checkUser()
{
var ajax = new Ajax(); // instantiates my external ajax class
var email = document.getElementById("newEmail").value;
var username = document.getElementById("newUserName").value
ajax.post("index.php?method=register&check=check", "newEmail=" + email + "&newUserName=" + username, callbackCatch)
}
function callbackCatch(param)
{
var responseMessages = JSON.parse(param.responseText);
emailMessage = responseMessages.emailMessage;
userNameMessage = responseMessages.userNameMessage;
userEmailIsOk = responseMessages.userEmailIsOk;
userNameIsOk = responseMessages.userNameIsOk;
release = true;
if((userEmailIsOk + userNameIsOk) != 2)
{
console.log(userEmailIsOk + userNameIsOk);
release = false;
}
updateMessageFields();
}
我得到一个 JSON 字符串，我对其进行解析，然后与我的表单值进行比较。当一切都找到后，我点击表单页面上的注册按钮，将所有字段发送回我的 php 文件。然而，似乎当我这样做时，每次都会以某种方式访问我的外部ajax类，并且我收到错误： NS_NOINTERFACE：组件没有请求的接口。
我假设因为每当我发帖时 AJAX 都会在后台运行，即使从我的表单中它也会尝试发回我的参数，在这种情况下这是不兼容的。
我不知道如何解决这个问题。我的 PHP 文件应该处理传输，如下所示：
require_once("../database/table.php");
班级测试{
private $SQLtable;
private $newEmail;
private $newPswrd;
private $newUserName;
private $newFullName;
public function test()
{
$this->SQLtable = new table();
$this->initClassVars();
$this->generateUserName();
$this->regUser();
}
function initClassVars()
{
if(isset($_POST["newPassword"]))
{
$this->newPswrd = $_POST["newPassword"];
}
if(isset($_POST['newUserName']))
{
$this->newUserName = $_POST['newUserName'];
}
if(isset($_POST["newEmail"]))
{
$this->newEmail = $_POST["newEmail"];
}
if(isset($_POST["newFullName"]))
{
$this->newFullName = $_POST["newFullName"];
}
}
function generateUserName()
{
if(isset($_POST["newFullName"]))
{
$suggestedUserName = str_replace(" ", "", $this->newFullName);
$this->newUserName = $suggestedUserName;
}
}
function regUser()
{
$this->SQLtable->registerUser($this->newEmail, $this->newPswrd, $this->newFullName, $this->newUserName);
$sessionKey = $this->genKey();
$this->SQLtable->authUser($this->newEmail, $this->newPswrd, $sessionKey);
header("location:Location:index.php?method=feed&key=$sessionKey&user=$this->newEmail");
exit;
}
function genKey($length = 16)
{
$options = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; //Range
$key = ""; //Empty holder for key
for($i = 0; $i < $length; $i++)
{
$code = rand(0, strlen($options) - 1);
$key .= $options[$code]; // Loops through as long as the $length is set and adds a random string char from $options to build a new key.
}
return $key;
}
}
正如你所看到的，我正在尝试使用 API 密钥来控制身份验证。我还没有让 cookie 与它一起工作，但在我弄清楚如何解决这个注册问题后，我会这样做。
抱歉，如果我不清楚。这是我在 stackoverflow 上的第一个问题，基本上我一生中从未写过一行代码，直到大约 8 个月前，所以请忍受我的新代码 :D。谢谢..
好的，这是 HTML 以及调用函数的位置：
这是我的表单 html 文件。当我一遍又一遍地使用它们时，文档类型和标题是单独添加的。
<body>
