我正在写一个Twitch WordPress状态插件，显示一个简单的图像，如果它的在线或离线，但我无法让它工作。下面是文件

<?php
/*
Plugin Name: Twitch Status - InvidiousAus
Description: Displays an image if the Twitch channel "invidiousaus" is online.
Author: Your Name
Version: 1.0
*/

function smfr_twitch_get_stream_status($channel) {
    $client_id = 'we57gvgtlmhqnmk44d3mcbc68rgrd1'; // Replace with your Twitch API Client ID

    $api_url = "https://api.twitch.tv/helix/streams?user_login={$channel}";
    $headers = array(
        'Client-ID' => $client_id,
    );

    $args = array(
        'headers' => $headers,
    );

    $response = wp_remote_get($api_url, $args);

    if (is_wp_error($response)) {
        return "Error fetching Twitch status.";
    }

    $response_code = wp_remote_retrieve_response_code($response);

    if ($response_code === 200) {
        $body = wp_remote_retrieve_body($response);
        $data = json_decode($body, true);
        if (!empty($data['data'])) {
            return 'online';
        }
    }

    return 'offline';
}

function smfr_twitch_status_fnc() {
    $channel = 'invidiousaus'; // Update to "invidiousaus"

    $stream_status = smfr_twitch_get_stream_status($channel);

    if ($stream_status === 'online') {
        // If the channel is live, show the "online" image
        $html = "<div class='smfr-twitch-status'><img src='" . plugin_dir_url(__FILE__) . "img/en_ligne.jpg'></div>";
    } else {
        // If the channel is offline, show the "offline" image
        $html = "<div class='smfr-twitch-status'><img src='" . plugin_dir_url(__FILE__) . "img/hors_ligne.jpg'></div>";
    }

    return $html;
}

function smfr_twitch_status_style() {
    // Register the stylesheet for the plugin (if needed)
    // wp_enqueue_style('smfr_twitch_status_style', plugin_dir_url(__FILE__) . 'style.css');
}
add_action('wp_enqueue_scripts', 'smfr_twitch_status_style');

add_shortcode('smfr_twitch_status', 'smfr_twitch_status_fnc');
