多线程中ThreadPoolExecutor.map()中传递多个参数

    with concurrent.futures.ThreadPoolExecutor(max_threads) as executor:results = executor.map(get_captcha_image, ip_addrs, [img_url] * len(ip_addrs)) #要传入多个参数时，每个参数都得是固定相同长度的可迭代对象# 收集结果for result in results:print(result)if result != None and len(result) > 10000:print("最后"+str(result))return result#return '1212'
