strong int htm utf %x lsp pri last 顯示
local ntime = os.time
print(ntime)
ngx.header["Last-Modified:"] = os.date("%a, %d %b %Y %X GMT")
ngx.header["Content-Type"] = "text/html; charset=utf-8"
ngx.header["Cache-Control"] = "public"
ngx.header["Expires"] = os.date("%a, %d %b %Y %X GMT", os.time() + cdnCacheTime)
一、系統當前時間對應的時間戳
復制代碼代碼如下:local ntime = os.time
print(ntime)
二、格式化時間顯示，參考下表
常用於設置header等
ngx.header["Last-Modified:"] = os.date("%a, %d %b %Y %X GMT")
ngx.header["Content-Type"] = "text/html; charset=utf-8"
ngx.header["Cache-Control"] = "public"
ngx.header["Expires"] = os.date("%a, %d %b %Y %X GMT", os.time() + cdnCacheTime)
