复制代码 代码如下:
local ntime = os.time
print(ntime)
二、格式化时间显示，参考下表
常用于设置header等
复制代码 代码如下:
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)
