simple openresty/lua library to auto parse parameters

parse openresty request data with simple rules.

Example 1

local xschema = require "xschema"

local Req = {
    page       = xschema.Number({default = 1, min = 1}),
    pagesize   = xschema.Number({default = 10, min = 5, max = 50}),
    keyword    = xschema.String({nonil = true})
}

local req, err = xschema.HttpParse(Req, ngx.req)
print(req.keyword)

Example 2

local Req = {
    userid    = xschema.Number({nonil = true}),
    imgs      = xschema.Array({
                    url  = xschema.String({nonil = true}),
                    size = xschema.Number({nonil = true, min = 1})
                })
}

local req, err = xschema.HttpParse(Req, ngx.req)
print(req.userid)

Example 3

local Req = {
    types     = xschema.Number({default = 0, must_in = {0, 2, 4, 6}}),
    ids       = xschema.Array('number')    -- number array
}
