lua遍历文件

看了不少人的，主要还是错误处理有点问题，不多说了

贴代码：

require "lfs"





function getpathes(rootpath, pathes)

    pathes = pathes or {}



    ret, files, iter = pcall(lfs.dir, rootpath)

    if ret == false then

        return pathes

    end

    for entry in files, iter do

        local next = false

        if entry ~= '.' and entry ~= '..' then

            local path = rootpath .. '/' .. entry

            local attr = lfs.attributes(path)

            if attr == nil then

                next = true

            end



            if next == false then 

                if attr.mode == 'directory' then

                    getpathes(path, pathes)

                else

                    table.insert(pathes, path)

                end

            end

        end

        next = false

    end

    return pathes

end



pathes = {}



getpathes("/", pathes)



for key, path in pairs(pathes) do

    print(key .. " " .. path)

end
