如何解决用纯php更新wordpress但用户密码需要保持不变

我想将我的小网站更新为纯 PHP。但是，用户将尝试使用他们的旧密码登录。

但是，我不能再使用 wordpress 身份验证功能了。如何，我将能够做到这一点？

如何验证我的用户？我想，我需要弄清楚wordpress的散列和加盐过程。在哪里可以找到？

解决方法

WordPress 的默认散列机制是 MD5。并且用户数据存储在db中的wp_users表中。

因此，您首先要考虑的是如何存储当前网站（非 WordPress）的密码。如您所知，PHP 具有内置的 md5() 函数。

如果您以纯文本格式存储它（根本不推荐），那么您可以简单地遍历当前数据库中的这些密码并将它们插入到 wp_users 表中（在您的新 WordPress 站点中） )，将密码传递给 md5() 函数。

如果您以加密形式存储它，即。稍后可以解密（不推荐），然后您也可以遍历密码，解密它，然后像上面那样插入到 wp_users 表中。

但是如果您使用的是单向加密（散列），并且是 MD5，那么您可以立即将存储在当前数据库中的散列密码插入到 WordPress 数据库中，它应该可以工作！

但如果不是MD5，那将是一项艰巨的任务。在这种情况下，我建议在 WordPress db 中插入用户数据，并在 user_pass 字段中插入临时随机密码。然后向用户发送一封电子邮件，其中包含以编程方式重置密码的链接。 WordPress 有一个名为 get_password_reset_key() 的内置函数，您可以使用类似的方法发送它：https://wordpress.stackexchange.com/a/275269/60666

我找到了确切的解决方案，我一直在寻找。如果你遇到同样的问题，我把它放在这里。

我只想用我的 wordpress 网站哈希验证我的密码。给你！！

您想使用 Core PHP 来实现，对吗？这是给你的代码！首先你需要添加一个类： -> 只需从 wp-includes/class-phpass.php 复制它 -> 别担心。它是用核心 PHP 编写的。

class PasswordHash {
    var $itoa64;
    var $iteration_count_log2;
    var $portable_hashes;
    var $random_state;

    /**

     */
    function __construct( $iteration_count_log2,$portable_hashes )
    {
        $this->itoa64 = './0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';

        if ($iteration_count_log2 < 4 || $iteration_count_log2 > 31)
            $iteration_count_log2 = 8;
        $this->iteration_count_log2 = $iteration_count_log2;

        $this->portable_hashes = $portable_hashes;

        $this->random_state = microtime() . uniqid(rand(),TRUE); // removed getmypid() for compatibility reasons
    }

    /**
     * PHP4 constructor.
     */
    public function PasswordHash( $iteration_count_log2,$portable_hashes ) {
        self::__construct( $iteration_count_log2,$portable_hashes );
    }

        if (strlen($hash) == 34)
            return $hash;

        # Returning '*' on error is safe here,but would _not_ be safe
        # in a crypt(3)-like function used _both_ for generating new
        # hashes and for validating passwords against existing hashes.

        $hash = $this->crypt_private($password,$stored_hash);
        if ($hash[0] == '*')
            $hash = crypt($password,$stored_hash);

        return $hash === $stored_hash;
    }
}

你快完成了。

$password = 'binary1001';//password you want to verify

$hasher = new PasswordHash(8,TRUE);
$passnya = '$P$BFG8I1k171qgRKqZvj0K3tn3bBSrsW/';//hash of that password from wp db


// compare plain password with hashed password
if ($hasher->CheckPassword( $password,$passnya )){
    echo "MATCHED";
} else {
    echo "NO MATCHED";
}

我通过反复试验做到了这一点。现在，是时候进入正题了。快乐编码！！！
