如何在一个服务中创建多个client?

多线程 问题

避免使用全局解释器锁（GIL）：
如果你的程序是 CPU 密集型的，使用多线程可能不是最佳选择，因为 Python 的 GIL 会限制多线程的并行执行。

使用线程池的示例代码：

import threading
from concurrent.futures import ThreadPoolExecutor
import time

def client(app_key, app_secret):
    credential = dingtalk_stream.Credential(app_key, app_secret)
    client = dingtalk_stream.DingTalkStreamClient(credential)
    client.register_all_event_handler(MyEventHandler())
    client.register_callback_handler(dingtalk_stream.ChatbotMessage.TOPIC, MyCallbackHandler())
    client.start_forever()

def main():
    with ThreadPoolExecutor(max_workers=2) as executor:
        futures = [
            executor.submit(client, "xxx", "xxx"),
            executor.submit(client, "yyy", "yyy")
        ]
        # 等待所有线程完成
        for future in futures:
            future.result()

if __name__ == "__main__":
    main()
