没什么解释，直接贴代码

cnid.lua 这个不是重点

--verify cnidfunction verify_cnid(id)--校验位local verifymap = {1, 0, 88, 9, 8, 7, 6, 5, 4, 3, 2}--加权因子local factor = {7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2}--加权和local sum = 0local index = 1while index ~= 18 do --身份证长18位sum = sum + (id[index]) * factor[index]index = index + 1end--求模11local r = sum % 11if verifymap[r + 1] ==  id[18] thenreturn trueelsereturn falseendend
