Lua中的字符串到表 [英] String to Table in Lua
本文介绍了Lua中的字符串到表的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在使用LuaSocket和http.request调用一个远程PHP脚本,该脚本会生成Lua表并将其输出到浏览器.
I am using LuaSocket and http.request to call a remote PHP script that generates a Lua table and outputs it to the browser.
当我将http.request响应存储在变量中时,它是一个字符串,这使该表在我的Lua代码中不可用.
When I store the http.request response in a variable it's a string, which renders the table unusable in my Lua code.
例如:
eventData = http.request("http://www.example.com/events.php")
print( eventData )
--print outputs this "string", that is really a Lua table that PHP generated
months={
'January',
'February',
'March',
'April',
'May',
'June',
'July',
'August',
'September',
'October',
'November',
'December',
}
例如,如果我尝试调用months [4],则会出现尝试索引全局'months'(nil值)"的错误. 如何将该字符串转换为可用表?
If I try calling months[4], for example, it errors out with "attempt to index global 'months' (a nil value)". How can I cast that string as a usable table?
谢谢!
推荐答案
You can use loadstring to create a lua chunk that you can execute.
eventData = [[
months = {
'January',
'February',
'March',
'April',
'May',
'June',
'July',
'August',
'September',
'October',
'November',
'December',
}
]]
loadstring(eventData)()
if months then
print(table.concat(months, ", "))
end
