如何使用 Python 解析 LUA 表并推送到 SQL 数据库？

Question

我玩了一款名为 DCS（数字战斗模拟器）的游戏，并希望将游戏统计数据导出到数据库，然后在网页上使用 PHP 进行调用。 游戏将代码保存到 LUA 表中，示例数据如下所示...

类别显示飞机类型、空中时间、被击毙的飞机、飞机类型、被击杀的飞机总数、武器、武器类型、命中、击杀、射击、动作、损失、飞行员死亡、坠机、弹射、pvp、击杀、加入日期、最后加入，姓名等。

我正在寻求有关如何分离示例数据中的值的建议（一种通过 Python 将 LUA 表解析为 SQL 的方法）并将它们全部绑定到 UUID（唯一用户标识），如字符串“b396452018d20452”所示。

我目前用来加载所有这些数据的 Python 代码如下...

import mysql.connector

# Make connection to DB with below...
db = mysql.connector.connect(
    host="192.168.1.20",
    user="user",
    passwd="password",
    db="database"
)
# Declare cursor
cursor = db.cursor()
# Open file to be read and imported to table in "database" database
file = open(r"C:\Users\Username\Desktop\slmodstats.lua", "r", encoding='utf-8')
file_content = file.read()
file.close()

# Debug for me to see what the file content is...
print(file_content, "\n")

# Send data to table VALUES type LONGTEXT as one long string (proof of concept)
# Push all that was read and is now "%s" from prior string and set query...
query = "REPLACE INTO data VALUES (%s);"
# insert all data from "query" and file content as %s, push to db
cursor.execute(query, (file_content,))
# Commit changes and close...
db.commit()
db.close()

有没有什么方法可以更轻松地解析 LUA 表文件中的数据，将其过滤到与 UUID 相关的类别，在看到“-- end of stats”时结束解析，并推送到数据库以最终显示 PHP一个网页？

问了很多，我很抱歉，但我已经研究了一段时间，结果很少。 我认为我有一个不错的基础。

仅使用 Lua 解析文件怎么样？

#!/usr/bin/env lua
dofile("stat.data")
for k,v in pairs(stats) do
    -- generate a data format that can be easily parsed by your program
    -- e.g. json
end

然后您可以使用 pipe 或临时文件来连接两个程序
