我想在wp(); 文件中的行wp-blog-header.php, 什么是正确的hook 在这里使用？

<?php
/**
 * Loads the WordPress environment and template.
 *
 * @package WordPress
 */

if ( !isset($wp_did_header) ) {

    $wp_did_header = true;

    // Load the WordPress library.
    require_once( dirname(__FILE__) . \'/wp-load.php\' );

    // Set up the WordPress query.
    wp();

    /********************************************
       I WANT TO RUN THE FUNCTION AT THIS POINT 
     ********************************************/

    // Load the theme template.
    require_once( ABSPATH . WPINC . \'/template-loader.php\' );

}

为什么我需要挂钩

我们正在迁移到一个新网站，我们必须关心旧的URL，所以我做了：

添加了以下内容rewrite 我们的规则NGINX 配置文件：

rewrite \\D+(\\/\\d+\\/\\D+)$ /index.php?redirect=$1 break;

此规则将添加一个额外参数redirect 到URL（旧URL），使用一个值，我将使用该值获取新的最终URL。

然后，我将运行以下代码从传入URL中获取该值，并通过查询映射每个值的2列表来获取最终URLredirect_from 具有最终URLredirect_to:

/**
 * 1. Check if the URL has a parameter [redirect]
 * 2. If NO, proceed to the next step
 * 3. If YES, then get that parameter value and look into [redirects] table
 * 4. If you found a row that has that value, then get the [redirect_to] value
 * 5. Redirect to that URL [redirect_to]
 */

if (isset($_GET[\'redirect\'])) {
    // Get the parameter value from the URL
    $redirect_from = $_GET[\'redirect\'];
    // Add the table prefix to the table name
    $table_name = $wpdb->prefix . \'redirects\';
    // The SQL query
    $query = "
        SELECT redirect_to
        FROM $table_name
        WHERE redirect_from = \'$redirect_from\';
    ";
    // Run the SQL query and get the results
    $result = $wpdb->get_results($query, OBJECT);

    // If there was a result then do the redirection and exit
    if (wp_redirect($result[0]->redirect_to)) {exit;}
}

Note:无法从旧URL获取新URL，以下是旧URL和新URL的示例：

    if (isset($_GET[\'redirect\'])) {

        $redirect_from = $_GET[\'redirect\'];
        // Add the table prefix to the table name

        // If there was a result then do the redirection and exit

    }
}
add_action( \'template_redirect\', \'wpse_331804_redirects\' );
