limit 是最大聊天数，由服务器发送到我的应用程序.offset_order 和 offset_chat_id 是什么?

@limit Maximum number of chats to be returned

推荐答案

(谷歌翻译)answer来自官方技术支持:

(Google translated) answer from official technical support:

聊天按降序排列一对 (offsetOrder, offsetChatId).offsetOrder - 用于聊天排序的参数，受控库.当Order相等时，chat按照ChatId的降序排序.第一个请求从头开始获取列表，需要传递非常大的offsetOrder，例如2^63 - 1.

Chats sorted in descending order a pair (offsetOrder, offsetChatId). offsetOrder - a parameter for sorting of chats, controlled library. When Order equality, chat to sort in descending order of ChatId. The first request to get a list from the beginning, you need to transfer very large offsetOrder, for example, 2 ^ 63 - 1.

如果 offsetOrder 是 2 ^ 63 - 1，offsetChatId 没有关系，你可以传 0.请求新的 GetChats (9223372036854775807L, 0, 10) 应该返回前 10 个会话.

if offsetOrder is 2 ^ 63 - 1, offsetChatId does not matter, you can pass 0. Request new GetChats (9223372036854775807L, 0, 10) should return the first 10 conversations.

需要将上次返回的chat.order chat.id传输到GetChats聊天以接收下一个聊天.另外值得记住的是，聊天的顺序是可以变化的，所以需要在获取结果GetChats的时候保留这些值.

It is necessary to transmit and chat.order chat.id last returned to the GetChats chat to receive next chats. It is also worth remembering that the order of chats can change, so you need to keep these values ​​at the time of obtaining the result GetChats.
