Question

我想在VCL中设置Cookie时指定到期日期。我现在有这样的事情：

add resp.http.Set-Cookie = "language=" + req.http.X-Language + "; path=/";

我知道我必须添加这样的东西：

Expires=Thu, 01 Jan 1970 00:00:00 GMT

Varnish中是否有内置函数允许我将过期日期动态设置为将来的任何内容？我一直在看他们的文档，但到目前为止没有运气。

非常感谢你。

Answer 1

更新 - 工作解决方案：

不确定此语法是否特定于Fastly，但我使用了time.add(now,1d)：

add resp.http.Set-Cookie = "language=" + req.http.X-Language + ";expires="+ time.add(now,1d) +"; path=/";

如果您使用Varnish 4，则应使用Cookie VMOD。来自文档：https://github.com/varnish/varnish-modules/blob/master/docs/vmod_cookie.rst

format_rfc1123

STRING format_rfc1123(TIME now, DURATION timedelta)
Description
Get a RFC1123 formatted date string suitable for inclusion in a Set-Cookie response header.

Care should be taken if the response has multiple Set-Cookie headers. In that case the header vmod should be used.

Example
sub vcl_deliver {
        # Set a userid cookie on the client that lives for 5 minutes.
        set resp.http.Set-Cookie = "userid=" + req.http.userid + "; Expires=" + cookie.format_rfc1123(now, 5m) + "; httpOnly";
}
