        "name": "on-line журнал РАЗНЫЕ ЛЮДИ",
        "id": "-2812448",
        "auId": "8911662942803793376",
        "email": "rl_journal",

    "isVip": false,
    "isCommunity": true,
    "isVideoChannel": false
}

您看到的数据在JSON format, you can convert it to a Python dictionary (dict) using the built-in json模块中，然后访问id键：

import json
from bs4 import BeautifulSoup

script_doc = """
<script data-mru-fragment="models/user/journal" type="text/plain">
    {
        "name": "on-line журнал РАЗНЫЕ ЛЮДИ",
        "id": "-2812448",
        "auId": "8911662942803793376",
        "email": "rl_journal",
        "dir": "/community/rl_journal/",
        "isVip": false,
        "isCommunity": true,
        "isVideoChannel": false
}</script>"""
soup = BeautifulSoup(script_doc, "html.parser")

json_data = json.loads(soup.find("script").string)
# With your example using `author_info`:
# json_data = json.loads(author_info.string)

输出：

>>> print(type(json_data))
<class 'dict'>

>>> print(json_data["id"])
-2812448
