首先用lua遍历目录：
1 function getDirs(path) 2 local s = {} 3 function attrdir(p) 4 for file in lfs.dir(p) do 5 if file ~= "." and file ~= ".." then 6 local f = p .. file 7 local attr = lfs.attributes (f) 8 if attr.mode == "directory" then 9 table.insert(s, f) 10 attrdir(f .. "/") 11 else 12 table.insert(s, f) 13 end 14 end 15 end 16 end 17 attrdir(path) 18 return s 19 end
然后将结果打包成JSON格式用于传递：
1 function string2JSON(path) 2 local s = getDirs(path) 3 local cjson = require("cjson") 4 local sJson = cjson.encode(s) 5 return sJson 6 end
最后用lwt后台输出到页面中：
1 require "httpd" 2 require "lfs" 3 4 request, args = ... 5 6 function getDirs(path) 7 local s = {} 8 function attrdir(p) 9 for file in lfs.dir(p) do 10 if file ~= "." and file ~= ".." then 11 local f = p .. file 12 local attr = lfs.attributes (f) 13 if attr.mode == "directory" then 14 table.insert(s, f) 15 attrdir(f .. "/") 16 else 17 table.insert(s, f) 18 end 19 end 20 end 21 end 22 attrdir(path) 23 return s 24 end 25 26 function string2JSON(path) 27 local s = getDirs(path) 28 local cjson = require("cjson") 29 local sJson = cjson.encode(s) 30 return sJson 31 end 32 33 httpd.set_content_type("text/plain") 34 httpd.write(string2JSON(request.filedir))
