cocos2dx lua中table与json互转

json字符串转table

json字符串

解析json

local str = [[{"done":[{"average":36.32,"id":5,"projectName":"???","state":1,"time":"2014-06-05","total":87.21},{"average":35.56,"id":3,"projectName":"???","state":1,"time":"2014-07-04","total":231.32},{"average":32.54,"id":2,"projectName":"???","state":1,"time":"2014-07-01","total":67.43}],"nodone":[{"average":14.4,"id":6,"projectName":"???","state":0,"time":"2014-07-07 ","total":43.21},{"average":12.44,"id":4,"projectName":"???","state":0,"time":"2014-07-05","total":34.21},{"average":13.31,"id":1,"projectName":"???","state":0,"time":"2014-07-05","total":27.32}]}
]]
local jstr = json.decode(str)
-- nodone project
table.foreach(jstr.nodone, function(key,var)
print(var.id.."-"..var.projectName.."-"..var.time.."-"..var.total.."-"..var.average.."-"..var.state)
end)
-- done project
table.foreach(jstr.done, function(key,var)
print(var.id.."-"..var.projectName.."-"..var.total.."-"..var.average.."-"..var.state)
end)

table转json字符串

local tb = {}
tb.aaa = "hello"
tb.bbb = "world"
tb.yang = true
tb.wilker = 123
tb.yun = 456.789
local str = json.encode(tb)
print(str)

打印结果：
