调用Volley时PHP 500内部服务器错误

我的Android应用程序中经常出现问题

基本上，我使用PHP和MYSQL数据库将用户注册并登录到我的应用程序中

注册很好。我能够连接到数据库并将新用户插入到表中，没有任何问题

我面临的问题是登录应用程序时。无论何时调用登录url，都会出现以下错误：

BasicNetwork.performRequest: Unexpected response code 500 for URL.

PHP Fatal error:  Call to undefined function checkHashSSA() in /xxx/xxx/xxx/xxx/UserFunctions.php on line 54

我尝试使用其他工具访问此url并手动发布参数，以消除错误可能来自我的应用程序代码的问题。事实上，我得到了一个

通用500内部服务器错误

。用这个工具也测试了注册URL，效果非常好

我的PHP类都调用同一个脚本来获取连接详细信息，因此这也没有问题，因为注册是有效的

下面是我的代码：

登录类：

    $password = $_POST['password'];

    $user = $db->getUserByEmailAndPassword($email, $password);
    $count = $db->getUserCount(); 

    if ($user != false) {
        $response["error"] = FALSE;
        $response["uid"] = $user["unique_id"];
        $response["user"]["name"] = $user["name"];

我找到了问题所在。 对于所有遇到非常严重错误500的人，请检查您的日志。我突然想到，在检查日志后，我发现从未使用过方法

checkhashSSHA（）

，这导致了以下错误：

BasicNetwork.performRequest: Unexpected response code 500 for URL.

PHP Fatal error:  Call to undefined function checkHashSSA() in /xxx/xxx/xxx/xxx/UserFunctions.php on line 54

因此，我添加了以下代码来解密密码：

public function getUserByEmailAndPassword($email, $password) {

    $stmt = $this->conn->prepare("SELECT * FROM users WHERE UserEmail = ?");

    $stmt->bind_param("s", $email);

    if ($stmt->execute()) {
        $user = $stmt->get_result()->fetch_assoc();
        $salt = $user['salt'];
        $userPassword = $user['UserPassword'];
        $hash = $this->checkhashSSHA($salt, $password);

        if ($userPassword == $hash) {
            return $user;
        }
        $stmt->close();
    } else {
        return NULL;
    }
}

这解决了我的错误

为了记录，此类错误的日志通常位于以下位置：

var/log/apache2/error.log

您可能需要对php.ini文件进行一些更改以记录这些错误

希望这能帮助有500个错误的人；）

500表示内部服务器错误。请检查服务器配置。500内部服务器错误还表示“代码中的某些错误或警告”。您是否检查过您的查询是否正确或连接文件“require_once”是否包含/DbConnect.php“；”没有错误吗？@riazhasan-服务器中没有任何错误。如果有，那么寄存器函数肯定不起作用。在评论之前，请阅读整个问题。@AjeetKumar-我在用于开发服务器端脚本的IDE上没有发现任何错误。请将代码放入try-catch语句中，然后发布结果
