API schema validation

[membphis]

the goal:

• code simplicity, we may add new feature to it
• open source and good performance
• pure Lua if possible

how about this:

-- JSON schema validation

old version which I designed, I think we can drop it.

local schema = {
    -- num1 = 0,
    num2 = "num",
    num3 = "int",
    -- num4 = {0, max = 100, min = 10},
    num5 = {"int", range={1, 10}, max = 10, min = 1, default = 2},
    -- str1 = "",
    str2 = "string",
    str3 = {"string", default = "a", max_len = 10, min_len = 1, dict = {"a", "b", "c"}},
    -- bool1 = true,
    bool2 = "bool",
    bool3 = {"bool", default = true},
    -- table1 = {},
    table2 = "table",
    table2 = "array",
    table2 = "hash",
    table3 = {"array", elements = {"int", dict={3, 4, 5}, max_len = 10, min_len = 1}},
    table4 = {"hash", elements = {
        -- sub schema
        num2 = "num",
        num3 = "int",
    }},
}

-- white mode: 只允许 schema 中描述定义的 key 值，不允许有任何多余
-- black mode: 允许出现 schema 描述之外的 key 存在
local conf = {
    sss = 1, -- 报错
}

Maybe you can try my https://github.com/tianchaijz/lua-resty-jsonschema validator.

https://github.com/Tencent/rapidjson/blob/master/example/schemavalidator/schemavalidator.cpp

This is also a good alternative.
