不和谐机器人可以存储信息的地方在哪里[discord.py] [英] Where is the place that discord bots can store information [discord.py]

问题描述

我对 python 并不陌生，但对 discord.py 并不陌生.我试图通过 discord.py 手册，但没有找到可以在 discord 机器人上存储一些临时变量的位置.

I am not too new to python but new to discord.py. I have tried to go through the discord.py manual but did not find where I can store some temporary variable on a discord bot.

discord.py 手册:http://discordpy.readthedocs.io/en/最新/api.html

discord.py manual: http://discordpy.readthedocs.io/en/latest/api.html

例如，在 PHP SESSION 中，我们可以在 SESSION() 中存储信息.discord.py 有同样的东西吗?

For example, in PHP SESSION, we can store information on the SESSION(). Did discord.py has the same kind of things?

例如，如果我们有用户A"和用户B".A"将存储为A_Object"的对象，例如消息等.与B_Object"类似，但与A_Object"不同.在discord.py中，有没有这样的函数?

For example, if we have user "A" and user "B". "A" will be stored as an object of "A_Object", such as messages etc. Similar for "B_Object" but will be different from "A_Object". In discord.py, is there a function like that?

非常感谢您的帮助！

推荐答案

可以使用sqlite数据库.在你的定义里面写:

You can use sqlite database. Write inside your def:

# define database
import sqlite3
conn = sqlite3.connect("my_database.db")
cursor = conn.cursor()
# get stored object from database
sql = "SELECT * FROM my_table WHERE field_1=?"
cursor.execute(sql, [(value_1)])
data = cursor.fetchall()
# if object does not exist, create it
if len(data) == 0:
    sql = "INSERT INTO my_table VALUES (?, ?)"
    cursor.execute(sql, [(value_1), (value_2)])
# if stored object exist and we need update it
elif ...:
    sql = "UPDATE my_table SET field_2 = ? WHERE field_1 = ?"
    cursor.execute(sql, [(value_2), (value_1)])
else:
    # get data from first object
    value_of_field_1 = data[0][0]
    # get data from third object
    value_of_field_2 = data[2][1]
# close database connection
conn.commit()
conn.close()

my_database.db - 是一个 sqlite db 文件，应该与 bot 的 .py 文件存储在同一文件夹中.

my_database.db - is a sqlite db file and should be stored in sa same folder with bot's .py file.
