lua语言 怎么将信息打印到界面
自己用代码写个打印信息到界面的函数，绑定到lua里，然后在lua里调用。
在Lua中运行print(os.date("%x", 906000490)),为什么输出是09/16/1998
你给的格式不对。
os.date ([format [, time]])
If format starts with '!', then the date is formatted in Coordinated Universal Time. After this optional character, if format is the string "*t", then date returns a table with the following fields: year (four digits), month (1--12), day (1--31), hour (0--23), min (0--59), sec (0--61), wday (weekday, Sunday is 1), yday (day of the year), and isdst (daylight saving flag, a boolean).
If format is not "*t", then date returns the date as a string, formatted according to the same rules as the C function strftime.
strftime的格式大致如下：
%a Abbreviated weekday name
%A Full weekday name
%b Abbreviated month name
%B Full month name
%c Date and time representation appropriate for locale
%d Day of month as decimal number (01 – 31)
%H Hour in 24-hour format (00 – 23)
%I Hour in 12-hour format (01 – 12)
%j Day of year as decimal number (001 – 366)
%m Month as decimal number (01 – 12)
%M Minute as decimal number (00 – 59)
%p Current locale's A.M./P.M. indicator for 12-hour clock
%S Second as decimal number (00 – 59)
%U Week of year as decimal number, with Sunday as first day of week (00 – 53)
%w Weekday as decimal number (0 – 6; Sunday is 0)
%W Week of year as decimal number, with Monday as first day of week (00 – 53)
%x Date representation for current locale
%X Time representation for current locale
%y Year without century, as decimal number (00 – 99)
%Y Year with century, as decimal number
%z, %Z Either the time-zone name or time zone abbreviation, depending on registry settings; no characters if time zone is unknown
%% Percent sign
Format code
%#c Long date and time representation, appropriate for current locale. For example: "Tuesday, March 14, 1995, 12:41:29".
%#x Long date representation, appropriate to current locale. For example: "Tuesday, March 14, 1995".
%#d, %#H, %#I, %#j, %#m, %#M, %#S, %#U, %#w, %#W, %#y, %#Y Remove leading zeros (if any).
怎么把如下php代码写成lua代码？
base64需要自己找个库调用一下，其他部分实现了，下面是代码
local function decode(str, skey)
str = str or ""
skey = skey or "cxphp"
local replaceStr = string.gsub(str, "O0O0O", "=")
replaceStr = string.gsub(replaceStr, "o000o", "+")
replaceStr = string.gsub(replaceStr, "oo00o", "/")
local strArr = {}
local replaceStrLen = string.len(replaceStr)
for pos = 1, replaceStrLen, 2 do
local posEnd = math.min(pos + 1, replaceStrLen)
strArr [#strArr + 1] = string.sub(replaceStr, pos, posEnd)
end
local strCount = #strArr
for key = 1, string.len(skey) do
local value = string.sub(skey, key, key)
print(key, value, strArr[key], string.sub(strArr[key], 2, 2))
if key = strCount and strArr[key] and string.sub(strArr[key], 2, 2) == value then
strArr[key] = string.sub(strArr[key], 1, 1)
end
end
local needToDecode = table.concat(strArr)
print(needToDecode)
-- TODO: find a lib base64_decode
end
