lua -- encode and decode

json.encode将表格数据编码为 JSON 字符串。格式：jsonString = json.encode(表格对象)用法示例：local str = json.encode({a=1,b="ss",c={c1=1,c2=2},d={10,11},100})echo(str) -- {"a":1,"b":"ss","c":{"c1":1,"c2":2},"d":[10,11],"1":100}local str = json.encode({1,2,"3",{10,11}})echo(str) -- [1,2,"3",[10,11]]Note: table作为字典使用时，整型键值将被转换为字符串键值local str = json.encode({a=1,[5]=3})echo(str) -- {"a":1,"5":3}Note: table所有键值为整型时，会当作数组看待，空位将转化为nulllocal str = json.encode({[3]=2,[5]=3})echo(str) -- [null,null,2,null,3]~~json.decode将 JSON 字符串解码为表格对象。格式：table = json.decode(string)用法示例：local json = require("framework.shared.json")local tb = json.decode('{"a":1,"b":"ss","c":{"c1":1,"c2":2},"d":[10,11],"1":100}')dump(tb) --[[- "<var>" = {-     "1" = 100-     "a" = 1-     "b" = "ss"-     "c" = {-         "c1" = 1-         "c2" = 2-     }-     "d" = {-         1 = 10-         2 = 11-     }- }]]local tb = json.decode('[1,2,"3",[10,11]]')dump(tb) --[[- "<var>" = {-     1 = 1-     2 = 2-     3 = "3"-     4 = {-         1 = 10-         2 = 11-     }- }]]
