用以下方法可以在页面内使用简码的方式调用DeepSeek对话框并进行对话

1.将以下代码添加到主题的functions.php文件中（记得替换你的API KEY）：

// 添加DeepSeek对话简码
add_shortcode('deepseek_chat', function(){
    wp_enqueue_script('deepseek-chat');
    
    return '<div class="deepseek-chat-container">
        <div class="chat-messages"></div>
        <div class="chat-input">
            <input type="text" placeholder="输入你的问题...">
            <button>发送</button>
        </div>
    </div>';
});

// 注册脚本
add_action('wp_enqueue_scripts', function(){
    wp_register_script('deepseek-chat', get_template_directory_uri().'/deepseek-chat.js', ['jquery'], '1.0', true);
    wp_localize_script('deepseek-chat', 'deepseek_vars', [
        'ajax_url' => admin_url('admin-ajax.php'),
        'nonce'    => wp_create_nonce('deepseek-nonce')
    ]);
});

// 处理API请求
add_action('wp_ajax_deepseek_chat', 'handle_deepseek_request');
add_action('wp_ajax_nopriv_deepseek_chat', 'handle_deepseek_request');

function handle_deepseek_request() {
    check_ajax_referer('deepseek-nonce', 'nonce');

    $api_key = 'your-api-key-here'; // 替换为你的API密钥
    $user_id = $_COOKIE['deepseek_session'] ?? uniqid();
    
    // 设置会话cookie（30分钟有效期）
    setcookie('deepseek_session', $user_id, time() + 1800, '/');

    // 获取或初始化对话历史
    $history = get_transient("deepseek_history_$user_id") ?: [];

    // 构建请求数据
    $messages = array_merge($history, [[
        'role' => 'user',
        'content' => sanitize_text_field($_POST['message'])
    ]]);

    $response = wp_remote_post('https://api.deepseek.com/v1/chat/completions', [
        'headers' => [
            'Content-Type'  => 'application/json',
            'Authorization' => 'Bearer '.$api_key
        ],
        'body' => json_encode([
            'model' => 'deepseek-chat',
            'messages' => $messages,
            'temperature' => 0.7
        ])
    ]);

    if (!is_wp_error($response)) {
        $body = json_decode($response['body'], true);
        $reply = $body['choices'][0]['message']['content'];
        
        // 更新对话历史（保留最近5轮对话）
        $updated_history = array_merge($messages, [[
            'role' => 'assistant',
            'content' => $reply
        ]]);
        
        if (count($updated_history) > 10) {
            $updated_history = array_slice($updated_history, -10);
        }
        
        set_transient("deepseek_history_$user_id", $updated_history, 1800);

        wp_send_json_success([
            'reply' => wp_kses_post($reply)
        ]);
    }

    wp_send_json_error(['error' => '请求失败，请重试']);
}

2.在主题目录中创建 deepseek-chat.js 文件：

jQuery(document).ready(function($) {
    $('.deepseek-chat-container').each(function() {
        const container = $(this);
        const messagesDiv = container.find('.chat-messages');
        const input = container.find('input');
        const button = container.find('button');

        function addMessage(content, isUser) {
            messagesDiv.append(`
                <div class="message ${isUser ? 'user' : 'bot'}">
                    ${content}
                </div>
            `);
            messagesDiv.scrollTop(messagesDiv[0].scrollHeight);
        }

        button.on('click', async function() {
            const message = input.val().trim();
            if (!message) return;

            addMessage(message, true);
            input.val('');
            
            try {
                const response = await $.ajax({
                    url: deepseek_vars.ajax_url,
                    type: 'POST',
                    data: {
                        action: 'deepseek_chat',
                        nonce: deepseek_vars.nonce,
                        message: message
                    }
                });

                if (response.success) {
                    addMessage(response.data.reply, false);
                }
            } catch (error) {
                addMessage('请求失败，请稍后再试', false);
            }
        });

        input.on('keypress', function(e) {
            if (e.which === 13) {
                button.click();
            }
        });
    });
});

3.添加CSS样式到主题的额外CSS设置中：

.deepseek-chat-container {
    max-width: 800px;
    margin: 20px auto;
    border: 1px solid #eee;
    border-radius: 8px;
    padding: 15px;
}

.chat-messages {
    height: 400px;
    overflow-y: auto;
    margin-bottom: 15px;
    padding: 10px;
    background: #f9f9f9;
    border-radius: 4px;
}

.message {
    margin: 10px 0;
    padding: 10px;
    border-radius: 4px;
    max-width: 80%;
}

.message.user {
    background: #e3f2fd;
    margin-left: auto;
}

.message.bot {
    background: #fff;
    border: 1px solid #eee;
}

.chat-input {
    display: flex;
    gap: 10px;
}

.chat-input input {
    flex: 1;
    padding: 8px;
    border: 1px solid #ddd;
    border-radius: 4px;
}

.chat-input button {
    padding: 8px 20px;
    background: #0073aa;
    color: white;
    border: none;
    border-radius: 4px;
    cursor: pointer;
}

4.创建页面

在新页面创建简码deepseek_chat

注意事项：

1. 上下文记忆基于WordPress Transient API实现，默认保留30分钟
2. 对话历史最多保留最近5轮（10条消息）对话
3. 需要申请并替换代码中的DeepSeek API密钥
