电报漫游器API对于每个与漫游器联系的用户而言，chat_id是唯一的吗? [英] Telegram bot API is the chat_id unique for each user contacting the bot?

问题描述

我们正在将python API用于电报机器人，并且需要能够识别用户.

We are using python API for telegram bots and need to be able to identify the user.

每个连接机器人的用户的chat_id是否唯一?

Is the chat_id unique for each user connecting the bot?

我们可以相信chat_id是一致的吗?例如，相同的chat_id会告诉我们这是同一用户，并且与漫游器连接的每个用户都将拥有一个在会话之间保持一致的chat_id?

Can we trust the chat_id to be consistent? e.g same chat_id will tell us that this is the same user, and each user connecting with the bot will have one chat_id that is consistent between sessions?

谢谢

推荐答案

每个连接机器人的用户的chat_id是否唯一?

Is the chat_id unique for each user connecting the bot?

是

chat_id始终是唯一的. 如果同一用户向不同的漫游器发送消息，他们将始终使用其唯一的id来标识"自己.

chat_id will always be unique for each user connecting to your bot. If the same user sends messages to different bots, they will always 'identify' themselves with their unique id.

请记住，getUpdates显示用户ID和聊天中的ID.

Keep in mind that getUpdates shows the users id, and the id from the chat.

{
    "ok": true,
    "result": [
        {
            "update_id": 1234567,
            "message": {
                "message_id": 751,
                "from": {
                    "id": 12122121,                     <-- user.id
                    "is_bot": false,
                    "first_name": "Me",
                    "last_name": "&",
                    "username": "&&&&",
                    "language_code": "en"
                },
                "chat": {
                    "id": -104235244275,                <-- chat_id
                    "title": "Some group",
                    "type": "supergroup"
                },
                "date": 1579999999,
                "text": "Hi!"
            }
        }
    ]
}

根据这篇文章，即使将组转换为超级组，chat.id也不会更改

According to this post, that chat.id will not change, even if the group is converted to a supergroup

基于评论；私人/群组聊天示例的小范围内容

Based on comment; small overvieuw of private/group chat example

user_1 ---> bot_a     in private chat
{
    "message": {
        "from": {
            "id": 12345678          <-- id from user_1
        },
        "chat": {
            "id": 12345678,         <-- send from private chat, so chat is equals to user_id
        }
    }
}

user_2 ---> bot_a     in private chat
{
    "message": {
        "from": {
            "id": 9876543          <-- id from user_2
        },
        "chat": {
            "id": 9876543,         <-- send from private chat, so chat is equals to user_id
        }
    }
}

user_1 ---> bot_a     in group chat
{
    "message": {
        "from": {
            "id": 12345678         <-- id from user_1
        },
        "chat": {
            "id": 5646464,         <-- send from group chat, so id is from groupchat
        }
    }
}

user_2 ---> bot_a     in group chat
{
    "message": {
        "from": {
            "id": 9876543          <-- id from user_2
        },
        "chat": {
            "id": 5646464,         <-- send from group chat, so id is from groupchat
        }
    }
}
