看起来 ChatGPT 用的是 eventsteam

建立 WebSocket 连接：

• 使用提供的 wss_url 或者 fallback_wss_url 来建立 WebSocket 连接。
• 确保在建立连接时使用了正确的访问令牌（access_token）。

发送消息请求：

• 在建立连接后，发送你希望模型继续生成的消息请求。你需要将当前的对话 ID (conversation_id) 和父消息 ID (parent_message_id) 包含在请求中。

接收消息响应：

• 监听 WebSocket 连接，接收服务器发送的响应消息。
• 响应消息中应该包含实际的输出内容。
